WebFlexor reflexes are spinal polysynaptic reflexes that can be produced by trains of electrical stimuli delivered to cutaneous or mixed nerves. 1 The normal flexor reflex consists of two EMG components. The first component appears at a higher threshold. Webduring spinal reflexes, the brain is advised of activity and may do what? alter activity by facilitating or inhibiting reflexes why are stretch reflexes (type of spinal reflex) important? posture, balance and locomotion how are stretch reflexes initiated? tapping tendon or ligament stretching muscle stimulating muscle spindles
Web11) Spinal interneurons prevent muscle antagonists from interfering with an intended movement by A) initiating a crossed extensor reflex. B) initiating a stretch reflex. C) initiating a tendon reflex. D) the process of reciprocal inhibition. E) activating reverberating circuits. : D Section Title: Skeletal Muscle Reflexes Learning Outcome: 13.10 WebPathologic reflexes (eg, Babinski, rooting, grasp) are reversions to primitive responses and indicate loss of cortical inhibition. Other reflexes Clonus (rhythmic, rapid alternation of muscle contraction and relaxation caused by sudden, passive tendon stretching) testing is done by rapid dorsiflexion of the foot at the ankle.
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.
