Question

What is Reflex Action? Explain its mechanism with diagram.

Answer 1

A reflex arc is a simple nervous pathway which is responsible for the sudden reaction known as the reflex action. The afferent/sensory neurons are present in the receptor organ which receive the stimulus. The neuron transmits the sensory information from receptor organ to the spinal cord. The CNS integrate the incoming information and signal is relayed to motor/efferent neurons. The motor pathway transmits the signal from motor neurons to the effector organs (muscles and glands etc).
