Explanation:
Detailed explanation-1: -The crossed extensor reflex is a contralateral reflex that allows the body to compensate on one side for a stimulus on the other. For example, when one foot steps on a nail, the crossed extensor reflex shifts the body’s weight onto the other foot, protecting and withdrawing the foot on the nail.
Detailed explanation-2: -The crossed extensor reflex is a withdrawal reflex.
