What are the two main organs of the CNS?

The nervous system has two main parts:

• The central nervous system is made up of the brain and spinal cord.
• The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

How will you differentiate the central nervous system CNS and the peripheral nervous system PNS in terms of their functions?

The Central Nervous System (CNS) includes the brain and spinal cord. The Peripheral Nervous System (PNS) connects the CNS to other parts of the body, and is composed of nerves (bundles of neurons).

How will you differentiate the central nervous system CNS and the peripheral nervous system PNS?

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.

What is the difference between the CNS and the PNS quizlet?

the CNS is the control center, brain and spinal cord. The PNS is nerve fibers that carry information to and from the CNS. White matter is myelinated fibers and is in the inside of the brain and outside of spinal cord. You just studied 85 terms!
