Reflexes That Activate Muscles on the Opposite Side of the Body

Question

Reflexes that activate muscles on the opposite side of the body as the stimulus are called
A) contralateral.
B) ipsilateral.
C) monosynaptic.
D) involuntary.
E) polysynaptic.

Accepted Answer

Contralateral reflexes activate muscles on the opposite side of the body from the stimulus. This happens because the sensory information crosses over to the opposite side of the spinal cord before it reaches the motor neurons that control the muscles.
