WebThe stretch reflex is a monosynaptic reflex that regulates muscle length through neuronal stimulation at the muscle spindle. The alpha motor neurons resist stretching by causing contraction, and the gamma motor neurons control the sensitivity of the reflex. The stretch and Golgi tendon reflexes work in tandem to control muscle length and tension.
