Which reflex requires gamma motor neurons to set the length

Which reflex requires gamma motor neurons to set the length of the muscle? flexor reflex stretch reflex crossed-extensor reflex tendon reflex

Solution

Stretch Reflex

Stretch Reflex is also a myotatic reflex. firing rate of sensory axons encode change in muscle length relative to \'set\' length. STRETCH RECEPTORS are muscle spindles responsible for changes in muscle length. The extrafusal fibers are either shortened (by contraction) or lengthened (by stretch). Stretch reflex of gamma motor neuron sets the length of the muscle.
