ANATOMY

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: -The PNS includes the peripheral nerves, neuromuscular junctions, cranial nerves, and spinal nerves. This system also carries information to and from the central nervous system. The peripheral nervous system (PNS) is made up of two divisions: the somatic nervous system and the autonomic system.

Detailed explanation-4: -There are 12 pairs of cranial nerves and 31 spinal nerve pairs, giving a total of 43 paired nerves forming the basis of the peripheral nervous system.

Detailed explanation-5: -The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord. The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.
