WebDec 17, 2010 · Muscle stretch reflex (myotatic reflex) is the function of the muscle spindle. Whenever a muscle is stretched, the excited spindles cause reflex contraction of the same muscle and also the synergistic muscles. WebThrough this system the gamma motor neurons form an important muscle stretch reflex mechanism that acts in conjunction with the alpha motor neurons. This sensitivity to stretch provides fine compensations of muscle length and velocity and helps maintain muscle tone. WebJan 15, 2024 · The stretch reflex also prevents us from tearing our muscles.
