Final answer:
The statement is False. The flexion-crossed-extension reflex is not related to the rate of locomotion.
Step-by-step explanation:
The flexion-crossed-extension reflex is not related to the rate of locomotion but rather pertains to a spinal reflex involved in response to a painful stimulus. When one leg experiences a noxious stimulus, it triggers a withdrawal reflex (flexion) in that leg, accompanied by an extension reflex in the opposite leg.
This coordinated response helps in withdrawing the affected limb while supporting the body's weight on the contralateral limb. It is a protective mechanism designed to swiftly respond to potential harm, showcasing the intricate reflex arcs within the spinal cord that contribute to motor coordination and injury avoidance. Hence, the statement is false.
