Anatomy and Physiology of the Nervous System: Introduction
1. What is the difference between anatomy and physiology?
Anatomy is the study of the structure of the body, while physiology focuses on
how the parts of the body function together.
2. The function of the nervous system is to integrate and control the other body
systems. Explain how the nervous system does this.
The nervous system integrates and controls the other body systems by receiving
information, processing it, and sending out signals to muscles and glands to
produce the desired response.
3. List the 2 parts of the nervous system.
The two parts of the nervous system are the central and peripheral nervous
systems.
4. How are the parts of the central nervous system protected?
The central nervous system is made of the brain and the spinal cord. The brain is
protected by the skull. The spinal cord is protected by vertebrae.

5. Collections of cell bodies inside the central nervous system are called _____,
and the collection of nerve axons in the central nervous system are called
_____.
Nuclei; tracts.
6. What is included in the peripheral nervous system?
The peripheral nervous system contains all nerves that are not within the brain
or spinal cord.
7. Collections of cell bodies inside the peripheral nervous system are called
_____, and the collection of nerve axons in the peripheral nervous system are
called _____.
Ganglia; nerves.
8. What are the 2 divisions of the peripheral nervous system?
The peripheral nervous system can be divided into the sensory and motor
divisions, also called the afferent division and efferent division.
9. Describe the movement of nerve impulses in the peripheral nervous system.
The peripheral nervous system receives messages called ‘impulses’ from the
afferent division and then passes impulses from the central nervous system
through the efferent division onto the muscles and glands.
10. What are the 2 divisions of the efferent division of the peripheral nervous
system?
The efferent division of the peripheral nervous system can also be divided into
the somatic nervous system and the autonomic nervous system.

11. What is controlled by the somatic and autonomic nervous systems?
The somatic system controls skeletal muscles, skin, and joints through
conscious control (generally). The autonomic nervous system controls the
glands and smooth muscles of internal organs without conscious control.
12. What are the 2 divisions of the autonomic nervous system?
The two divisions of the autonomic nervous system are the sympathetic and
parasympathetic nervous systems.
13. What is the function of the sympathetic nervous system?
The sympathetic nervous system comes into play when the body is going to be
moving vigorously such as in stress and emergencies.
14. What is the function of the parasympathetic nervous system?
The function of the parasympathetic nervous system is to operate for digestion
and conserve energy in moments where high levels of activity are not occurring.
