Question

Define reflex action. State it's significance.​

Answer 1

A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus.[1][2] A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain. The reflex is then an automatic response to a stimulus that does not receive or need conscious thought.[3]
