Detailed explanation-1: -The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands. Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.

Detailed explanation-2: -Your peripheral nervous system (PNS) is one of two main parts of your body’s nervous system. Your PNS feeds information into your brain from most of your senses. It carries signals that allow you to move your muscles.

Detailed explanation-3: -The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord. These nerves form the communication network between the CNS and the body parts. The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.

Detailed explanation-4: -The peripheral nervous system contains both the autonomic and sensory-somatic nervous systems. The autonomic nervous system provides unconscious control over visceral functions and has two divisions: the sympathetic and parasympathetic nervous systems.

Detailed explanation-5: -Cranial nerves emerge from the cranium (brain/brainstem) whilst spinal nerves leave the CNS via the spinal cord. 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.
