How to Research and Prepare for NURS 6630 Wk 1 Assignment: Short Answer Assessment 

 

Whether one passes or fails an academic assignment such as the Walden University  NURS 6630 Wk 1 Assignment: Short Answer Assessment  depends on the preparation done beforehand. The first thing to do once you receive an assignment is to quickly skim through the requirements. Once that is done, start going through the instructions one by one to clearly understand what the instructor wants. The most important thing here is to understand the required format—whether it is APA, MLA, Chicago, etc.

 

After understanding the requirements of the paper, the next phase is to gather relevant materials. The first place to start the research process is the weekly resources. Go through the resources provided in the instructions to determine which ones fit the assignment. After reviewing the provided resources, use the university library to search for additional resources. After gathering sufficient and necessary resources, you are now ready to start drafting your paper.

 

How to Write the Introduction for NURS 6630 Wk 1 Assignment: Short Answer Assessment 

 

The introduction for the Walden University  NURS 6630 Wk 1 Assignment: Short Answer Assessment  is where you tell the instructor what your paper will encompass. In three to four statements, highlight the important points that will form the basis of your paper. Here, you can include statistics to show the importance of the topic you will be discussing. At the end of the introduction, write a clear purpose statement outlining what exactly will be contained in the paper. This statement will start with “The purpose of this paper…” and then proceed to outline the various sections of the instructions.

 

How to Write the Body for NURS 6630 Wk 1 Assignment: Short Answer Assessment  

 

After the introduction, move into the main part of the NURS 6630 Wk 1 Assignment: Short Answer Assessment  assignment, which is the body. Given that the paper you will be writing is not experimental, the way you organize the headings and subheadings of your paper is critically important. In some cases, you might have to use more subheadings to properly organize the assignment. The organization will depend on the rubric provided. Carefully examine the rubric, as it will contain all the detailed requirements of the assignment. Sometimes, the rubric will have information that the normal instructions lack.

 

Another important factor to consider at this point is how to do citations. In-text citations are fundamental as they support the arguments and points you make in the paper. At this point, the resources gathered at the beginning will come in handy. Integrating the ideas of the authors with your own will ensure that you produce a comprehensive paper. Also, follow the given citation format. In most cases, APA 7 is the preferred format for nursing assignments.

 

How to Write the Conclusion for NURS 6630 Wk 1 Assignment: Short Answer Assessment 

 

After completing the main sections, write the conclusion of your paper. The conclusion is a summary of the main points you made in your paper. However, you need to rewrite the points and not simply copy and paste them. By restating the points from each subheading, you will provide a nuanced overview of the assignment to the reader.

 

How to Format the References List for NURS 6630 Wk 1 Assignment: Short Answer Assessment 

 

The very last part of your paper involves listing the sources used in your paper. These sources should be listed in alphabetical order and double-spaced.

Sample Answer for NURS 6630 Wk 1 Assignment: Short Answer Assessment

Anatomy of the neuron.

The neuron is mainly made up of soma, dendrites, and axon. According to Allen and Lyons (2018), soma acts as the neuron’s core while dendrites obtain synaptic inputs, and lastly, the axon, which resembles a tail-like structure, generates action potential action. As a result, the nerve impulse starts from the dendrite and then goes to soma and towards the axon. While at the axon, the synapse crosses towards the postsynaptic nerve cell after passing the nerve impulse, resulting in the action potential.Axon sizes varies length wise. For instance, when a myocardium experiences an electrical impulse, such impulse begins at the sinoatrial node within the right atrium towards the atrioventricular node, with the impulse traveling down to the conduction pathway through the HIS of  bundle aims to stimulate the two ventricles to pump blood to the body.

What are the major components that make up the subcortical structures?

  • The basal ganglia.
  • limbic structures
  • pituitary gland
  • Diencephalon

Which component plays a role in learning, memory, and addiction?

  • Dopamine

What are the two key neurotransmitters located in the nigra striatal region of the brain that play a major role in motor control?

The key neurotransmitters are;

  • Pars compacta (SNpc) that contain dopaminergic neurons
  • Pars Reticula (SNpr) contains gamma-aminobutyric acid-containing neurons (Lin et al., 2021)

How glia cells function in the central nervous system

Glia cells are commonly known as the non-neuronal cells within the peripheral and central nervous systems. The

NURS 6630 Wk 1 Assignment Short Answer Assessment
NURS 6630 Wk 1 Assignment Short Answer Assessment

main roles that glia cells have include protecting and supporting the neurons, forming myelin, and maintaining homeostasis (Allen & Lyons, 2018). Glia cells usually exist in three categories; microglial cells that protect the brain immune against diseases and injury, oligodendrocytes that supports the neuron’s axons within the brain, and astrocytes that control neurotransmitter levels within the synapse by controlling the ions concentration.

Communication.

When the action potential or the electrical impulse gets to the presynaptic vesicles, it triggers neurotransmitters’ contents released from the neurons. These neurotransmitters then become responsible for transporting the signal through the synaptic gap toward the receptors’ sites in the postsynaptic cell (Allen & Lyons, 2018). Depending on the positivity or negativity of ions such as NA+ and K+ , the signal travels across various channels connecting the membrane until the synaptic transmission process is complete.

“Neuroplasticity”

The neuroplasticity concept refers to the brain’s ability to change, adapt, and modify to function and structure throughout an individual’s life while responding to their experiences and activity. According to Carey et al. (2019), neuroplasticity explains how neuropathways become reorganized when the brain registers new experiences. Consequently, through neuroplasticity, the brain nerve cells can easily compensate for brain diseases and injuries such as the impact that a stroke may cause. Another example of neuroplasticity occurs when memorizing and learning new information since the change occurs at the neural connections. Neuroplasticity is activity driven, will be lost if not used.

Sample Answer 2 for NURS 6630 Wk 1 Assignment: Short Answer Assessment

Neurons are information messengers with three main parts namely the cell body, axon, and the dendrites (Kringelbach et al., 2020). The cell body is made up of a nucleus and cytoplasm and produces protein required to construct other parts of the neuron. The axon, on the other hand, extends from the cell body and carries signals away from the cell body while the dendrites carry signals toward the cell body and have numerous synapses to receive the signal from nearby neurons. Upon stimulation, neurons transmit an electrical impulse that passes through the dendrite, to the cell body, axon, axon terminal, and finally, the stimulus is passed (Kringelbach et al., 2020). At the axonal terminal, the axon releases neurotransmitters that depolarize neighboring cells through synapses and by binding to the membrane of the dendrite.

Subcortical Structures

Other structures within the brain are subcortical structures that act as information hubs for the nervous system. Their main role is to relay and modulate information circulating in different areas of the brain. They include the basal ganglia, limbic structures, pituitary gland, and the diencephalon (Malinowski, 2019).

The limbic systems play a great role in learning and memory addiction.  The systems provide the anatomical substrate for emotions and motivated behaviors, including the circulatory for reward-related events and stress responses. Specifically, the hippocampus is used to mediate a cognitive/spatial form of memory. It controls learning and declarative memory which covers the memory of facts and events (Malinowski, 2019).  The dorsal striatum also helps in memory by mediating the stimulus-response habit memory. Addiction on the other hand is linked to the limbic system through the orbitofrontal cortex and anterior cingulate gyrus (Malinowski, 2019).

In line with motor control, the nigra striatal region offers two anatomically and functionally distinct portions knowns as the substantia nigra pars compacta and the substantia nigra pars reticulata.

Glial Cells

Other essential components in the central nervous system are the glial cells. They include the astrocytes whose role is to maintain the environment for neuronal signaling by controlling the level of neurotransmitters surrounding the synapses (Hirbec et al., 2020). Equally, oligodendrocytes wrap around the axons forming a protective layer called myelin sheath which enhances neuron signaling. The cells also include microglia, ependymal cells, and radial glial whose roles are clearing dead cells or removing harmful toxins, maintaining homeostasis, and regenerating neurons and other glial cells like astrocytes and oligodendrocytes respectively.

Neuron Communication

Neurons communicate with each other through synaptic transmission. A chemical synapse is registered at the axon terminal of the presynaptic neuron and the dendrite of the postsynaptic neuron (Malinowski, 2019). The dendrite picks up signals and passes the signals down to the axon, into the axon terminals, and into the synapses. The role of the chemical synapse is to transform the electrical signal in the presynaptic cell’s axon into a chemical signal and back into an electrical signal in the postsynaptic cell.

Neuroplasticity

Brain plasticity denotes the ability of the brain to reorganize itself and form new neural connections in response to extrinsic or intrinsic stimuli.  Through axonal sprouting, the undamaged axons develop new nerve endings and reconnect neurons with severed or injured links (Mateos-Aparicio & Rodríguez-Moreno, 2019). For instance, undamaged brain sites of stroke patients rewire themselves to take over functions of the damaged brain sites. Similarly, the undamaged axons sprout nerve endings that connect with other undamaged nerve cells to form new neural pathways (Mateos-Aparicio & Rodríguez-Moreno, 2019).   For example, exposing the brain to specific grammatical rules helps it process and develop language.

Sample Answer 3 for NURS 6630 Wk 1 Assignment: Short Answer Assessment

Short Answer Assessment   

  1. In 4 or 5 sentences, describe the anatomy of the basic unit of the nervous system, the neuron. Include each part of the neuron and a general overview of electrical impulse conduction, the pathway it travels, and the net result at the termination of the impulse. Be specific and provide examples.

According to Javaid et al. (2020), the human brain comprises over 100 billion distinct neurons. The neuron’s cell body harbors the nucleus and serves as the point of attachment for both the dendrites and axons of the neuron. The term “soma” is sometimes used to refer to the cell body, while axon clusters, commonly referred to as nerves in some contexts, can be found throughout the body in various locations. Neurons can interact with one another even when they are separated by large distances, which is made possible by the fact that they contain dendrites and axons. Furthermore, owing to the mechanism of electrical conduction intrinsic to neurons, nerve impulses can propagate at a remarkable pace, marked by a transient electrical oscillation that traverses from the neuronal soma, through its dendrites, and culminates at the terminal end of the axon.

  1. Answer the following (listing is acceptable for these questions):
    • What are the major components that make up subcortical structures?
      1. Basal ganglia: Pertains to a cluster of subcortical nuclei that are primarily accountable for regulating motor control (Wilfrid Jänig, 2022). Additionally, they play a crucial role in executive functions, motor learning, and emotional and behavioral regulation.
      2. Limbic structure: The limbic system is responsible for the regulation of motivation, mood, learning, and memory through its intricate network of structures and interconnected regions(Wilfrid Jänig, 2022). The interface between the subcortical structures and the cerebral cortex is located within the limbic system. The limbic system exerts its influence on the autonomic nervous system and the endocrine system
      3. Thalamic structures: The structure in question comprises four distinct components, namely the thalamus, epithalamus, subthalamus, and hypothalamus. Each of the aforementioned structures plays a crucial role in the survival and optimal operation of the human body (Wilfrid Jänig, 2022). Therefore, it is imperative to familiarize oneself with their anatomy.
      4. Cerebellar: The cerebellum is a neuroanatomical structure situated in the posterior cranial fossa, superior and posterior to the pontomedullary junction, where the spinal cord merges with the brainstem. The aforementioned structure is a significant subcortical entity that has an impact not only on motor function but also potentially on cognitive and emotional processes (Wilfrid Jänig, 2022).                
    • Which component plays a role in learning, memory, and addiction?

According to Wilfrid Janig (2022), the limbic structure contributes to the capacity of the human body to acquire new information and retain it. Furthermore, it assumes a crucial function in the control of cognitive attention and behaviors that are addictive.

    • What are the two key neurotransmitters located in the nigra striatal region of the brain that play a major role in motor control?
      1. Dopamine: While the activity of dopaminergic cells cannot directly dictate movements, a recent study conducted on humans has indicated that the consistent levels of dopamine present in the dorsal striatum may contribute to the facilitation of regular motion by encoding the sensitivity to the energy expenditure of a movement (Skelin et al., 2019). This implicit signal can be interpreted as a “motor motivational” cue.
      2. Gamma-aminobutyric acid (GABA): It is widely distributed throughout the nervous system and plays a crucial role in inhibiting the transmission of signals. It is essential for regulating movement, both in the cortex and subcortical regions of the brain.
  1. In 3 or 4 sentences, explain how glial cells function in the central nervous system. Be specific and provide examples.

The phrase “glial cells” may refer to several different kinds of glial cells, including astrocytes, Schwann cells, oligodendrocytes, and microglial cells all of which have a unique role in ensuring that the brain continues to operate normally (Yang & Zhou, 2019). Astrocytes are responsible for controlling blood flow, as well as supplying neurons with mitochondria and the components necessary to construct neurotransmitters, which are the driving force behind neuronal metabolism. Schwann cells play an essential role in the development, maintenance, functioning, and regeneration of peripheral nerves. Oligodendrocytes are chiefly accountable for the production and upkeep of the myelin sheath that envelops axons within the nervous system while microglia are enduring brain cells that govern brain maturation, the safeguarding of neural networks, and the recuperation from injuries.

  1. The synapse is an area between two neurons that allows for chemical communication. In 3 or 4 sentences, explain what part of the neurons are communicating with each other and in which direction does this communication occur? Be specific.

When an action potential is generated at the chemical synapse, the neuron at the presynaptic cleft is stimulated, which results in the release of neurotransmitters, which are the molecules that are responsible for transporting information being propagated from the presynaptic gap to the postsynaptic cleft, which is where it is accepted by another cell. The dendrite of the receiving neuron is the one that is responsible for receiving the message from the axon terminal of the transmitting neuron. Because one axon may create synapses on a large number of postsynaptic cells, it can interact with a large number of cells (Stadelmann et al., 2019). As a consequence of this, a single neuron may receive information from the other neurons since it is capable of receiving millions of synaptic inputs from a wide variety of neurons that are responsible for transmitting presynaptic signals.

  1. In 3–5 sentences, explain the concept of “neuroplasticity.” Be specific and provide examples.

Neuroplasticity, commonly referred to aseither brain plasticityor neural plasticity, denotes a phenomenon wherein the brain encounters adaptive modifications in both functional and structural domains. The nervous system is capable of modifying its activity in response to both internal and external stimuli through the process of restoring its functions, pattern, or connections following events such as cerebrovascular incidents or traumatic brain injuries (Innocenti, 2022). These alterations may be helpful in that they lead to the regeneration of function after an injury, neutral in that there is no change, or pathologically detrimental with the resulting pathological consequences.The notion of neuroplasticity can be deconstructed into two primary mechanisms, which are functional reorganizationand collateral sprouting/neuronal regeneration.

Sample Answer 4 for NURS 6630 Wk 1 Assignment: Short Answer Assessment

Major Depressive Disorder

Mood disorders are the most common mental health illnesses encountered by populations. Major Depressive Disorder (MDD) is a type of mood disorder characterized by sadness or depressed mood, which is persistent for two weeks. Other symptoms of MDD include loss of interest in everyday activities, loss/gain of appetite, loss/gain of weight, lack of energy, feelings of guilt, low concentration, sleep disturbances, and sometimes suicidal thoughts. in most cases, MDD co-occurs with substance use disorder. Substance use can be the cause of depression or a consequence of the illness, which results from the maladaptive need to cope with the negative impact of the depression (Alsheikh et al., 2020). The presence of substance use disorder complicates the treatment of the underlying depression. The purpose of this assignment is to demonstrate knowledge of pharmacological treatment for patients with multiple mental health conditions.

Drug Therapy

The appropriate drug therapy for a patient with an alcoholism problem is Paroxetine, based on evidence for its effectiveness in treating social anxiety in patients with alcohol abuse problems (Gimeno et al., 2018). In general, alcohol use while taking antidepressants is not advisable because of the risk of drug-induced depression or exacerbating central nervous side effects such as drowsiness, confusion, and dizziness (Agabio et al., 2018). Some MDD drugs that are contraindicated with alcohol include Bupropion because of the risk of seizure and duloxetine due to the increased risk of liver damage. Finally, it takes 4 to 8 weeks for the remission of MDD symptoms.

  1. List 4 predictors of late-onset generalized anxiety disorder
  • Childhood issues such as parental loss/separation/inadequate support
  • History of parental mental illness
  • Poverty
  • Recent adverse life events (Welzel et al., 2021)
  1. List 4 potential neurobiology causes of psychotic major depression.
  • Default Mode Network (DMN) functional connectivity
  • Abnormalities in the subgenual cortex
  • Decreased gamma-Aminobutyric acid neurotransmission(Croarkin, 2018)
  • DMN hyperactivity
  1. Symptoms of an episode of major depression
  • Feelings of sadness or hopelessness
  • Irritability or anger outbursts
  • Sleep disturbances
  • Agitation or restlessness
  • Lack of energy
  • Trouble concentrating
  • Feelings of worthlessness
  1. Drugs that precipitate insomnia
  • Selective serotonin reuptake inhibitors example Zoloft (Xu et al., 2022)
  • Anticonvulsants for example Topiramate
  • Beta-agonists for example propranolol

Conclusion

MDD is a mood-based disorder characterized by episodes of extreme sadness, loss of energy or interest in activities, sleep disturbances and other symptoms that often last for two weeks. When MDD occurs in a person with a history of alcohol abuse, treatment becomes challenging because mixing antidepressants with alcohol can cause more damage, for example, further induce depression. Therefore, it is important to evaluate the risk and benefits of the antidepressant for every patient and closely monitor them to determine tolerability. Some antidepressant drugs are contraindicated in people with alcohol use disorder, for example, duloxetine and Bupropion because they can cause serious side effects such as seizures. Finally, people with MDD undergo an episode of depression characterized by sadness, loss of energy, sleep disturbances, agitation, restlessness, issues with appetite, and trouble concentrating.
