Question

Explain the mechanism of reflex action.

Accepted Answer

To understand the mechanism of reflex action, we have to have an idea about the components involved in a reflex action. So there are five components involved in a reflex action: receptor (present in sense organ), afferent neuron, brain/spinal cord, efferent neuron, and effector organ (muscle or gland).

The mechanism of a reflex action is mentioned below.

The sensory nerve fibres bring sensory impulses from the receptor organ (sensory organ) to the organs of the central nervous system. The CNS interprets the information and send the response to the effector organs like muscles and glands via motor nerve fibres, resulting in an impulse travel path called the reflex arc.
