what do we call a reflex that causes an effect on the opposite side of the body?
ipsilateral
contralateral
monosynaptic
visceral

Explanation:

First Question (about muscle reflex)

• Tendon reflex (also called Golgi tendon reflex) responds to muscle tension by causing the muscle to relax and lengthen to prevent injury from excessive tension.
• Flexor reflex is for withdrawing from a painful stimulus (flexing muscles).
• Crossed - extensor reflex coordinates movements on opposite sides of the body (e.g., when one leg flexes, the other extends).
• Plantar reflex is a response to stimulation of the sole, related to foot movement and neurological testing. So the correct answer for the first question is the tendon reflex option.

• Ipsilateral reflexes have effects on the same side of the body as the stimulus.
• Contralateral reflexes have effects on the opposite side of the body from the stimulus.
• Monosynaptic refers to a reflex arc with one synapse (e.g., knee - jerk reflex).
• Visceral reflexes involve internal organs. So a reflex with an effect on the opposite side is contralateral.

Answer:

A. tendon reflex
