Chapter 1: Overview of the Central and Peripheral Nervous Systems

Question 1

What are the two main systems of the nervous system?

Answer 1

The two main systems of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS).

Question 2

What does the central nervous system (CNS) consist of?

Answer 2

The central nervous system (CNS) consists of the brain and spinal cord.

Question 3

What are the functions of the central nervous system (CNS)?

Answer 3

responsible for processing and integrating sensory information, coordinating motor commands, and regulating higher cognitive functions.

Question 4

What does the peripheral nervous system (PNS) consist of?

Answer 4

The peripheral nervous system (PNS) consists of nerves and ganglia located outside the brain and spinal cord.

Question 5

What is the function of the peripheral nervous system (PNS)?

Answer 5

The peripheral nervous system (PNS) connects the central nervous system (CNS) to the rest of the body and carries sensory information from the body to the CNS and motor commands from the CNS to the muscles and glands.

Question 6

What structures make up the central nervous system (CNS)?

Answer 6

The central nervous system (CNS) is made up of the brain and spinal cord.

Question 7

What structures make up the peripheral nervous system (PNS)?

Answer 7

The peripheral nervous system (PNS) is made up of all the nerves and their ganglia (bundles of cell bodies) that do not stay entirely within the brain and spinal cord.

Question 8

How many pairs of cranial nerves are there in the peripheral nervous system (PNS)?

Answer 8

There are twelve pairs of cranial nerves in the peripheral nervous system (PNS) that contain neurons traveling to and from the brain.

Question 9

How many pairs of spinal nerves are there in the peripheral nervous system (PNS)?

Answer 9

There are 31 pairs of spinal nerves in the peripheral nervous system (PNS) that contain neurons traveling to and from the spinal cord.
