Nervous System

  1. The nervous system comprises of the central nervous which is made up of the spinal cord, brain, and peripheral nervous system that are made up of nerves arising from the spinal cord to other body parts. Neuron is the basic unit of the nervous system. The neuron has parts that include nerves, cell body, nucleus, axons, and dendrites. Electrical impulse transmission such as sensation of pain comprises of an action potential that is generated in the brain or organ, action potential is transmitted to the neuron, axon where it is transformed into chemical signal, release of neurotransmitters that move through the synapse to the next dendrite where it is converted to electrical signal. The process repeats itself until the signal reaches the target organ where it is terminated.
  2. The major components of subcortical structures include the basal ganglia, cerebellum and thalamus. The parts of the subcortical structures that are involved in learning and memory include cerebellum, hippocampus, prefrontal cortex, and amygdala. The cerebellum plays a role in addiction. The neurotransmitters that are located in the nigra striatal region of the brain and play the role in motor control include acetylcholine and dopamine.
  3. Glia cells play the role of maintaining homeostasis in the central nervous system. The cells form myelin and support the neurons. Glia cells also protect neurons by insulating them from one another. The other roles of glia cells include removing dead neurons and killing any pathogens that target neurons (Camprodon & Roffman, 2016). An example of homeostatic role played by glia cells in the central nervous system is buffering the chemicals and ions that are detrimental to the neurons and forming myelin sheath for the neuron that regulates the internal environment of the neuron.
  4. Synapses are the part of the neurons that communicate with each other. Communication in neurons occurs in one direction. For example, when an action potential is generated in sensory muscle, the action potential moves from sensory neurons to the spinal cord where the information is relayed to the brain for processing. The direction of flow of information is terminated once the sensory information is acted upon in the brain through the initiation of a response.
  5. Neuroplasticity refers to the ability of the brain to change as well as adapt due to experience. Neuroplasticity exists in two types that include structural and functional neuroplasticity. Functional neuroplasticity is the ability of the brain to transfer its functions from a side of brain that is damaged to undamaged region while structural plasticity is the ability of the brain to transform its physical structure due to learning. Neuroplasticity is important because it enables learning, development of cognitive abilities, and recovery from conditions such as traumatic brain injuries (Camprodon & Roffman, 2016). An example of neuroplasticity is the restoration of motor functions that had been lost following traumatic brain injury or stroke.

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.

Next week, you will examine how neurotransmitters and receptor theory may impact the function of the central nervous system. You explore medication adherence and consider how it might impact a patient’s treatment goals.

Practicum – Upcoming Deadline

In the Nurse Practitioner programs of study (FNP, AGACNP, AGPCNP, and PMHNP) you are required to take several practicum courses. If you plan on taking a practicum course within the next two terms, you will need to submit your application via Meditrek .

For information on the practicum application process and deadlines, please visit the Field Experience: College of Nursing: Application Process – Graduate web page.

Please take the time to review the Appropriate Preceptors and Field Sites for your courses.

Please take the time to review the practicum manuals, FAQs, Webinars and any required forms on the Field Experience: College of Nursing: Student Resources and Manuals web page.

Next Week

Week 2

Week 1: Introduction to Neuroanatomy

The human brain is organized into the cerebral cortex, brainstem, subcortical structures, and the cerebellum. These anatomical structures are made of inter-connected elements that create distributed and highly inter-connected circuits. It is in these circuits where cognition, behavior, and affect are processed.

—Camprodon, J. A., & Roffman, J. L. (2016, p. 6)

By using a combination of psychotherapy and medication therapy, psychiatric nurse practitioners (PNP) are positioned to provide a very unique type of care to patients with psychiatric disorders. To be successful in this role, you must have a strong theoretical foundation in pathophysiology, psychopharmacology, and neuroscience. This foundation will help you assess, diagnose, and treat patients as you relate presenting symptoms to theoretical neuronal functioning.

This week, as you begin to study psychopharmacology, you will explore the basic functional unit of the nervous system, the neuron. You will review the structure of the neuron and you will examine the anatomy of the central nervous system and consider the functionality of the different structure and outward (phenotypic) expression of their activities. You will analyze these concepts as you complete your short answer assessment for this week.  Short Answer Assessment Assignment NURS 6630

Optional Discussion Forum: PMHNP Study Support Lounge
The PMHNP Study Support Lounge is offered throughout the course as a place of academic refuge, where you can ask questions, offer insights, and interact with your peers. Your Instructor may also weigh in to provide global feedback to the group based on trends, common problems, and common strengths in student posts.

As a peer, you are encouraged to provide constructive, helpful feedback to your peers. Advanced practice nurses always benefit from the feedback of others. Your Study Support Lounge posts may be procedural (“How do I attach a Kaltura video to a Discussion post?”), conceptual (“How does this relate to the other therapy approaches we have studied?”), or analytical (“What do these diagnostic results actually mean in the context of this specific patient case?”). Although not mandatory, this is an opportunity to interact and study together as you navigate the assignments, so you are highly encouraged to take part in this activity. Full participation in activities like these is a statistically significant predictor of success.
