The Peripheral Nervous System consists of:

• A. The entire network of nerves located outside the CNS that transmits information to and from the CNS.
• B. Nerves located exclusively within the brain.
• C. A network of nerves only within the spinal cord.
• D. Nerves that regulate the endocrine glands.

Answer: (A)

The peripheral nervous system consists of the entire network of nerves located outside the central nervous system that transmits information to and from the CNS. It includes all the nerves that branch from the brain and spinal cord to reach muscles, skin, and organs, letting us sense the world and act in it. It also contains the somatic part, handling voluntary movements and conscious sensations, and the autonomic part, which regulates involuntary functions such as heartbeat and gland activity. The other statements aren’t correct because nerves inside the brain and the spinal cord are part of the central nervous system, not the peripheral. And while autonomic nerves influence glands, the peripheral nervous system is not limited to endocrine regulation—it's the broader network connecting the CNS to the rest of the body.
