Peripheral nerve

Peripheral nerve

A Peripheral nerve is a type of nerve that is located outside of the brain and spinal cord. These nerves are responsible for carrying information between the central nervous system and the rest of the body. They are a key part of the peripheral nervous system, which also includes the autonomic nervous system and the enteric nervous system.

Structure

Peripheral nerves are composed of many different types of neurons, including sensory neurons, motor neurons, and interneurons. These neurons are bundled together in a protective sheath known as the myelin sheath, which helps to speed up the transmission of nerve impulses.

Function

The primary function of peripheral nerves is to transmit information between the central nervous system and the rest of the body. This includes both sensory information, such as touch and temperature, and motor information, such as movement and coordination.

Clinical significance

Damage to peripheral nerves can result in a variety of neurological disorders, including peripheral neuropathy, Guillain-Barré syndrome, and Charcot-Marie-Tooth disease. These conditions can cause symptoms such as pain, numbness, and weakness in the affected areas.
