WebSince at the time of the muscle stretch its antagonist was contracting, in order to avoid damage it must be inhibited or tuned off in the reflex. So an additional connection through an interneuron sends an inhibitory pathway to the antagonist of the stretched muscle - this is called reciprocal inhibition. The Deep Tendon Reflex: (See Figure 13.16) WebThe 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 too much tension on ... cse shiseido

WebAlthough muscle tension is increasing during the contraction, the alpha motor neurons in the spinal cord that supply the muscle are inhibited. However, antagonistic muscles are … WebFeb 1, 2024 · In parallel, an inhibitory impulse is sent from the spinal cord to cause relaxation of the hamstring muscles, via a polysynaptic pathway. It is important to note that, even with the simplest of reflexes, there are multiple inhibitory and stimulatory influences that can affect the excitability of the motor neuron. WebThe myotatic reflex is initiated by the muscle threaded, not and Golgi strain organ.)
