Question

Define 'reflex action' and how is reflex arc formed?​

Answer 1

A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus. A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.

In reflex actions, a reflex arc is formed by impulses from the receptor reaching the spinal cord and the appropriate reflex impulse then being sent to the muscles by the spinal cord. The impulse is not sent to the brain, to reduce response time.
