Expert Answer:

Reflex arc is the neural pathway involved in a reflex action.

A reflex arc usually consists of five elements; receptor, sensory neuron, an integration centre (e.g. an association neuron in the central nervous system; this may be absent in some reflex arcs), a motor neuron, and a muscle that acts as the effector.


A reflex action, also known as a reflex, is an involuntary (often) and instantaneous movement or action in response to a stimulus.
