Detailed explanation-1: -Stepping on a piece of glass with the left foot will result in extension of the right leg to help maintain balance. This is an example of a(n) b. contralateral reflex. This is because the movement is occurring on the opposite side of the body as to where the stimulus occurs.
Detailed explanation-2: -Crossed Extensor Reflex The reflex occurs when the flexors in the withdrawing limb contract and the extensors relax, while in the other limb, the opposite occurs. An example of this is when a person steps on a nail, the leg that is stepping on the nail pulls away, while the other leg takes the weight of the whole body.
Detailed explanation-3: -The crossed extensor reflex or crossed extensor response or crossed extension reflex is a reflex in which the contralateral limb compensates for loss of support when the ipsilateral limb withdraws from painful stimulus in a withdrawal reflex.
Detailed explanation-4: -Pushing down hard on a sharp/unsafe object hurts more, but rapid flexion and extension of the opposite leg enables you to quickly transfer your body weight to the left foot and step away with the hurt right foot. This is the protective motor pattern of the Leg Cross Flexion-Extension Reflex.
