The term peripheral nervous system (PNS) refers to any part of the nervous system that lies outside of the brain and spinal cord. The CNS is separate from the

Each system contains afferent and efferent components. The afferent arm consists of sensory (or afferent) neurons running from receptors for stimuli to the CNS. 2021-02-21 · The peripheral nervous system (PNS) is the network of nerves that send information from all parts of the body to the brain and spinal cord, a group called the central nervous system (CNS).

The Peripheral Nervous System (PNS) connects the CNS to other parts of the body, and is composed of nerves ( Peripheral Nervous System : Example Question #1.

The Peripheral Nervous System . The peripheral system (PNS) is composed of nerves that extend outside of the central nervous system. The nerves and nerve networks that make up the PNS are actually bundles of axons from neuron cells. The nerve bundles can be relatively small or large enough to be easily seen by the human eye.

peripheral nervous system The part of the nervous system in vertebrate animals that lies outside of the brain and spinal cord (central nervous system). It includes the nerves that extend to the limbs and many sense organs. Compare central nervous system. The peripheral nervous system branches outside of the central nervous system and is comprised of nerves and neurons that transmit information to and from the brain. It is further divided into two parts called the somatic nervous system and the autonomic nervous system . Peripheral nerves send messages from your brain and spinal cord to the rest of your body, helping you do things such as sensing that your feet are cold and moving your muscles so that you can walk. Made of fibers called axons that are insulated by surrounding tissues, peripheral nerves are fragile and easily damaged.
