Scope note

  • Motor neurons which activate the contractile regions of intrafusal SKELETAL MUSCLE FIBERS, thus adjusting the sensitivity of the MUSCLE SPINDLES to stretch. Gamma motor neurons may be "static" or "dynamic" according to which aspect of responsiveness (or which fiber types) they regulate. The alpha and gamma motor neurons are often activated together (alpha gamma coactivation) which allows the spindles to contribute to the control of movement trajectories despite changes in muscle length.

History note

  • 91(79); was see under MOTOR NEURONS 1979-90; was MOTOR NEURONS, GAMMA EFFERENT see under MOTOR NEURONS 1975-78
