GAMMA MOTOR NEURON Meaning and
Definition
-
A gamma motor neuron is a specialized type of motor neuron found in the spinal cord that controls the contraction of muscle fibers in the intrafusal muscle fibers of the muscle spindle. It is named as such because the electrical activity generated by these neurons typically falls within a specific range of frequencies called the gamma band, typically between 30 and 120 Hz.
Gamma motor neurons work in conjunction with alpha motor neurons to maintain muscle tone and regulate muscle spindle sensitivity. Unlike alpha motor neurons, which innervate the extrafusal muscle fibers responsible for generating force and movement, gamma motor neurons innervate the intrafusal muscle fibers within the muscle spindle.
The muscle spindle is a sensory receptor that provides continuous feedback about the length and rate of change in length of muscles. By controlling the sensitivity of the muscle spindle, gamma motor neurons help regulate muscle tone and ensure precise muscle control during movement. When activated, gamma motor neurons cause the contraction of the intrafusal muscle fibers, which in turn stretches the sensory endings of the muscle spindle, resulting in increased sensitivity and enhanced proprioceptive feedback.
Overall, gamma motor neurons play a crucial role in motor control and proprioception, enabling the body to maintain posture, control movement, and accurately perceive the position of limbs and muscles in space.
