Question

With the help of a neat and labelled diagram, describe reflex arc.

Answer 1

A reflex arc is the pathway of transmission of nerve impulse which controls the nerve action. Sensory receptors receive the stimulus from the organs and conveys is to the central nervous system by sensory neuron. Interneuron carries the impulse from one neurone to the other. The stimulus is converted to the response by the brain which is carried to the effector by the motor neuron.
