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

As a psychiatric nurse practitioner, you will almost certainly encounter patients suffering from a variety of mental health issues. Not surprisingly, ensuring that your patients have access to the appropriate psychopharmacologic therapy is critical to their general health and well-being. The psychopharmacologic treatments you may propose for patients may have an impact on other mental health issues, necessitating more thought for favorable patient outcomes. You will evaluate and use your knowledge of psychopharmacologic therapy for people with numerous mental health conditions for this Assignment.
