The Efferent nerve is a type of nerve that carries impulses away from the central nervous system to effectors such as muscles and glands. This is in contrast to afferent nerves, which carry impulses towards the central nervous system.

Structure

Efferent nerves are part of the peripheral nervous system and connect the central nervous system to the organs and tissues of the body. They are composed of axons, which are long, slender projections of neurons that conduct electrical impulses.

Function

The primary function of efferent nerves is to relay commands from the central nervous system to the rest of the body. These commands can be either voluntary, such as moving a muscle, or involuntary, such as regulating the heartbeat.

Clinical significance

Damage to efferent nerves can result in a variety of symptoms, depending on the specific nerve and location of the damage. Symptoms can include muscle weakness, loss of coordination, and loss of sensation.
