As a psychiatric nurse practitioner, before you can recommend potential pharmacotherapeutics to address
a patient’s condition or disorder, you must understand the basic function and structure of the neuron and
central nervous system. For this Assignment, you will review and apply your understanding of
neuroanatomy by addressing a set of short answer prompts.
Review the Learning Resources for this week in preparation to complete this Assignment.
Reflect on the basic function and structure of the neuron in relation to the central nervous system.
Reflect on the inter-connectedness between neurons and the central nervous system, including the
pathway and distribution of electrical impulses.
Reflect on how neurons communicate with each other and review the concept of neuroplasticity.

Address the following Short Answer prompts for your Assignment. Be sure to include references to the
Learning Resources for this week.
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.
Answer the following (listing is acceptable for these questions):
What are the major components that make up the subcortical structures?
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?
In 3 or 4 sentences, explain how glia cells function in the central nervous system. Be specific and provide
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.
In 3–5 sentences, explain the concept of “neuroplasticity.” Be specific and provide examples.
