flexor reflex
Quick Summary
The flexor reflex is a protective withdrawal reflex that removes a limb from a noxious stimulus. It involves a minimum of two interneurons and three synapses within the central nervous system. This reflex is distinct from the stretch reflex, which has only one synapse between the afferent nerve fiber and the motor neuron. Flexor muscles are those that decrease the angle between bones at a joint, such as bending the elbow or knee.12

human nervous systemReciprocal innervationThe flexor and extensor reflexes are only two examples of the sequential ordering of muscular contraction and relaxation. Underlying this basic organization is the principle of reciprocal innervation—the contraction of one muscle or group of muscles with the relaxation of muscles that have the opposite function.…
