Crossed extensor reflex action prevents one from falling when your foot catches while walking.
Crossed extensor reflex:
- 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.
- 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 connect with interneurons there, which then stimulate or inhibit alpha motor neurons to the muscles of the opposing leg.
