Answer 2

Answer:

A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus.Reflex action is a rapid, automatic action carried out without the intervention of the will of the animal. It is independent of the will of the animal.

The path taken by the nerve impulses in a reflex is called a reflex arc. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the reflex action occurs.
