The withdrawal reflex (nociceptive flexion reflex or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. [1] The reflex rapidly coordinates the contractions of all the flexor muscles and the relaxations of the extensors in that limb causing sudden withdrawal from the potentially damaging stimulus. [2]
An example of this is when a person steps on a nail: The leg that is stepping on the nail pulls away, while the other leg takes the weight of the whole body. [ 4 ] The crossed extensor reflex is contralateral, meaning the reflex occurs on the opposite side of the body from the stimulus.

It acts as the strongest flexor of the hip. The iliopsoas muscle is supplied by the lumbar spinal nerves L1–L3 (psoas) and parts of the femoral nerve ...
