A
in the brain and spinal cord
B
in the brain only
C
in the spinal cord only
D
outside of the brain and spinal cord
Explanation: 

Detailed explanation-1: -Peripheral nerves reside outside your brain and spinal cord. They relay information between your brain and the rest of your body. The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.

Detailed explanation-2: -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.

Detailed explanation-3: -Your central nervous system includes two organs, your brain and spinal cord. Your peripheral nervous system is everything else and includes nerves that travel from your spinal cord and brain to supply your face and the rest of your body.

Detailed explanation-4: -The PNS is composed of nerves that are responsible for carrying signals between the central nervous system and the parts of the body that lie outside the CNS. This includes information from the senses, organs, and muscles. The axons of these nerve cells are bundled together and can be found throughout the body.

Detailed explanation-5: -There are two types of cell found in the peripheral nervous system. These are neurons and neuroglia. The neurons are the nerve cells, that generate and transmit nerve impulses. The neuroglial cells, also known as Schwann cells, provide support and insulation for the neurons.
