The term peripheral nerve refers to which of the following?

• A. Central nervous system
• B. Nerve root
• C. Ganglion
• D. Peripheral nerve

Answer: (D)

A peripheral nerve is a bundle of nerve fibers that lies outside the brain and spinal cord, forming the conduit that carries motor commands and sensory information between the central nervous system and the rest of the body. It’s made of many axons wrapped in connective tissue and includes both sensory and motor fibers. The central nervous system refers to the brain and spinal cord, not peripheral nerves. A nerve root is the initial portion that exits the spinal cord and is only a part of the pathway, not the whole nerve. A ganglion is a cluster of neuron cell bodies along a nerve, not the nerve itself. So the term peripheral nerve precisely describes the actual nerve bundle functioning in the periphery.
