Module 2: Body Systems: Nervous

Introduction

This module reviews the anatomy and physiology of the nervous system and explores key neurotransmitters, receptors, and pharmacological agents that are used to treat conditions like pain, epilepsy, and depression. You'll learn about drug classes that affect nerve signaling, their mechanism of action, physiological effects, and side effects. Understanding these concepts is essential in healthcare due to the pivotal role of the nervous system in major bodily functions, such as breathing, thinking, and feeling.

Learning Objectives 

1. Identify the roles and mechanisms of neurotransmitter clearance processes (diffusion, reuptake, enzymatic degradation) in the nervous system.
2. Apply pharmacokinetic and pharmacodynamic principles to explain the effects of cholinergic and adrenergic agents on the nervous system.
3. Compare and contrast the pharmacology, therapeutic uses, and side effects of CNS stimulants and depressants, including their impact on neurotransmitter systems.
4. Evaluate the therapeutic applications and potential risks of opioid and non-opioid analgesics in pain management.
5. Discuss the mechanisms of action, benefits, and risks of antipsychotics and antidepressants in the treatment of mental health disorders.
