What are the 3 divisions of the PNS?
The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division. The afferent or sensory division transmits impulses from peripheral organs to the CNS.
What are the main divisions of the PNS?
The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system. The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities.
What does the PNS contain?
The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.
How many divisions are in the PNS?
The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system.
What are the 6 main components of the PNS?
Overview of the Peripheral Nervous System
| Components | Functions |
|---|---|
| *All the nerves in the body outside of the spinal cord and brain *Includes sensory cells, motor nerve cells, and somatic cells | *Connects the central nervous system to the parts of the body *Relays information and responses *Controls body functions |
What are the parts of the CNS and PNS?
The nervous system is comprised of two major parts, or subdivisions, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord. The PNS is a vast network of spinal and cranial nerves that are linked to the brain and the spinal cord.
What are the divisions of the PNS choose all that apply?
Divisions of the Peripheral Nervous System. The PNS is divided into two major systems, called the autonomic nervous system and the somatic (or sensory-somatic) nervous system. Both systems of the PNS interact with the CNS and include sensory and motor neurons, but they use different circuits of nerves and ganglia.

What are the components of CNS and PNS?
Definition, Parts and Function The CNS is made up of the brain and the spinal cord components. The PNS is all the nerves that branch out from the CNS components and extend to other parts of the body – to the sense organs, muscles, and glands. The PNS connects the CNS to the rest of the body.

What are the major components of the CNS and PNS?
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.
