Crossed-extensor reflex prevents you from falling when you suddenly lift one foot off the ground in response to pain.
- A withdrawal reflex is the crossed extensor reflex. In the withdrawing limb, the extensors relax while the flexors contract, but in the other limb, the opposite happens.
- This can be seen, for instance, when someone steps on a nail; the affected leg pulls away, while the other leg bears the weight of the entire body.
- Contralateral means that the crossed extensor reflex takes place on the side of the body that is opposite from the stimulus.
- Afferent nerve fiber branches travel from the stimulated side of the body to the opposite side of the spinal cord to cause this response.
- They make connections with interneurons there, which then stimulate or inhibit alpha motor neurons to he muscles of the contralateral limb.
