Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Reflexes that activate muscles on the opposite side of the body as the stimulus are called ____
A
voluntary
B
monosynaptic
C
ipsilateral
D
contralateral
Explanation: 

Detailed explanation-1: -The crossed extensor reflex is contralateral, meaning the reflex occurs on the opposite side of the body from the stimulus. To produce this reflex, branches of the afferent nerve fibers cross from the stimulated side of the body to the contralateral side of the spinal cord.

Detailed explanation-2: -Crossed-Extensor Reflex. In this reflex, as withdrawal from the damaging stimulus occurs in the ipsilateral leg, extension occurs in the contralateral leg as a way of maintaining balance.

Detailed explanation-3: -As a result of activity in this circuitry, stimulation of nociceptive sensory fibers leads to excitation of ipsilateral flexor muscles and reciprocal inhibition of ipsilateral extensor muscles.

Detailed explanation-4: -Reflexes that involve cranial nerves such as accommodation reflex, gag reflex, glabellar reflex, jaw jerk reflex, pupillary light reflex, blink reflex, and vestibulo-ocular reflex.
