Gamma motor neurons

A) are located in tendons.
B) transmit action potentials to skeletal muscle.
C) regulate the sensitivity of the muscle spindle.
D) enable the brain to perceive that a muscle has been stretched.
E) innervate the whole muscle.

Gamma Motor Neurons

Neurons that control the contraction of intrafusal muscle fibers in muscle spindles, helping to regulate muscle tone and sensitivity of stretch reflexes.

Muscle Spindle

A sensory receptor located within muscles that detects changes in muscle length, contributing to the sense of body position.

Action Potentials

Rapid and temporary changes in the electrical membrane potential of a cell, allowing for the transmission of nerve impulses along neurons.
