Components of reflex arc

The neural circuit for reflex is referred to as reflex arc. Five components commonly make up a reflex arc. They are the receptor organ, sensory (afferent) neurons, interneurons in spinal cord or brain, motor neurons (efferent) and an effector organ (muscle or glands).

Classification of reflex arcs

Neurons may combine to give at least five types of reflex arcs- Monosynaptic reflex arc and Polysynaptic arcs.

Monosynaptic reflex arc

There is a single synapse between sensory and motor neurons of the spinal cord (without interneuron) e.g Myotatic reflex.
