The withdrawal reflex involves the activation of sensory neurons that stimulate motor neurons to withdraw the limb from a potentially harmful stimulus. The sciatic nerve is responsible for this reflex in the lower limb. Therefore, if baby Jackie is not exhibiting the withdrawal reflex, it is possible that her sciatic nerve has been damaged. The other nerves listed do not play a significant role in the withdrawal reflex.
