This reflex begins inside the muscle spindle of the muscle, which detects both the amount and rate of muscle stretch.
WebGolgi tendon reflex. The Golgi tendon reflex [1] (also called inverse stretch reflex, autogenic inhibition, [2] tendon reflex [3] ) is an inhibitory effect on the muscle resulting from the muscle tension stimulating Golgi tendon organs (GTO) of the muscle, and hence it is self-induced. The reflex arc is a negative feedback mechanism preventing ... WebIn somatic reflexes, the effector is skeletal muscle. In autonomic (visceral) reflexes, the effector is smooth or cardiac muscle, or a gland. A reflex arc.
