the Nervous System
After completing this lesson, you should be able to:
- Identify definitions of a neuron, nerve tissue, neuroglia,
cell body, axon, dendrite, and synapse.
- Identify the components of a neuron including the
characteristics and functions of each.
- Identify the types of neurons according to structure and
function.
- Identify the steps in the sequence of nerve impulse
transmission.
- Identify the locations of the major components of the
central nervous system.
- Identify the characteristics and functions of the major
components of the central nervous system.

About this Course
The central nervous system (CNS) is one of the
two principal divisions of the body's nervous system. The nervous system is the body's
communication network and control center. Consisting of the brain and the spinal cord,
the CNS is the control center for the entire nervous system. All the sensations of
the body are relayed to the central nervous system. All nerve impulses that cause muscles
to contract and glands to secrete come from the central nervous system.
This course deals with the anatomy and
physiology of the central nervous system, physical assessment of the central nervous
system, central nervous system diseases and disorders, seizures, and central nervous
system trauma. It is a suitable foundation course in the central nervous system for
technologists and professionals in the medical arts. |
