Question

the flexor reflex
usually depends on cranial neurons.
prevents a muscle from overstretching.
prevents a muscle from rupturing its tendon.
is an example of a monosynaptic reflex.
moves a limb away from a painful stimulus.

Explanation:

The flexor reflex is a polysynaptic reflex (not monosynaptic) that occurs in response to a painful stimulus. It functions to move a limb away from the source of the painful stimulus. Cranial neurons are not usually involved in the flexor reflex (it is mainly a spinal reflex). The stretch reflex (not the flexor reflex) prevents a muscle from overstretching. The Golgi tendon reflex (not the flexor reflex) prevents a muscle from rupturing its tendon.

Answer:

moves a limb away from a painful stimulus.
