MEDICAL PHYSIOLOGY

Detailed explanation-1: -Efferent neurons, also called motor neurons, are the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system in order to initiate an action. In other words, they are the neurons that tell your body to perform an action, such as removing your hand from a hot pan.

Detailed explanation-2: -The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division.

Detailed explanation-3: -Motor neurons are also known as efferent neurons, meaning they carry information from the CNS to muscles, and other peripheral systems such as organs and glands.

Detailed explanation-4: -Overall, motor neurons (or motoneurons) comprise various tightly controlled, complex circuits throughout the body that allows for both voluntary and involuntary movements through the innervation of effector muscles and glands. The upper and lower motor neurons form a two-neuron circuit.

Detailed explanation-5: -Motor nerves act as efferent nerves which carry information out from the CNS to muscles, as opposed to afferent nerves (also called sensory nerves), which transfer signals from sensory receptors in the periphery to the CNS.
