Organization and Control of Neural Function Case Study
This week, you will become familiar with the cells of the nervous system, the function of neurons, the excitable nature of neuronal cells, the classification scheme of neuronal fibers, electrical and chemical synapses, neurotransmitter classification, and neurotransmitters’ function as excitatory or inhibitory agents. You should pay attention to how neurotransmitter function is altered by other agents.
The first presentation covers the cells of the nervous system and examines neuronal physiology, including describing the movement of the electrical signal, presenting the classification scheme of neurons, detailing the role of synapses in transferring the electrical signal, and describing neurotransmitters in detail.
Learning Outcomes
At the end of this lesson, you will be able to:
Nervous System Cells
Distinguish between the functions of the neurons and neuroglial cells of the nervous system
Describe the structure and function of the three parts of a neuron
Describe the metabolic requirements of nervous tissue
Describe the three phases of an action potential and relate the functional importance of ion channels to the different phases
Characterize the role of excitatory and inhibitory postsynaptic potentials (IPSPs) as they relate to spatial and temporal summation of membrane potentials
Neuronal Synapses and Neurotransmitters
Describe a neural synapse, and be able to distinguish between axoaxonic, axiomatic, and axodendritic synapses
Describe how neurotransmitters are synthesized, stored, released, and inactivated

The material for this lesson is in the presentation titled Nervous System Physiology and Pathophysiology. This material presents the higher and lower organization of the nervous system. The purpose of this material is to make you aware of the morphology and roles of the various regions of the brain and spinal cord, as well as the protective mechanisms in the brain, i.e., meningeal tissue, cerebrospinal fluid, and the blood-brain barrier. In light of the fact that strokes are the third leading cause of death, you should be able to describe the blood supply to the brain.
Learning Outcomes
At the end of this lesson, you will be able to:
Nervous System Organization
Describe the general organizational scheme of the nervous system
Compare and contrast the functional areas of the brain
Brain Protective Mechanisms
Describe the role of the brain meningeal tissues and cerebrospinal fluid as protective mechanisms
Understand the critical role of the blood-brain barrier
Describe the blood supply to the brain
Neuronal Tracts
Define the terms afferent, efferent, ganglia, association neuron, cell column, and tract
Autonomic Nervous System
Compare the sensory and motor components of the autonomic nervous system with those of the CNS
Cranial Nerves and Reflexes
List the cranial nerves and the spinal cord segments
Understand the pathway involved in a reflex response
