Question

what is the difference between reflex action and reflex arc ?​

Answer 1

A reflex arc defines the pathway by which a reflex travels—from the stimulus to sensory neuron to motor neuron to reflex muscle movement.

A reflex action, also known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus. When a person accidentally touches a hot object, they automatically their hand away without thinking. A reflex does not require any thought input
