what is relay neuron class 10

A relay neuron is a neuron in the central nervous system that connects a sensory neuron to a motor neuron and passes the nerve impulse between them. In Class 10 biology, it is also called an association neuron or interneuron.

Quick Scoop

• Location: brain and spinal cord, especially the spinal cord in reflex actions.

• Function: it relays signals from sensory neurons to motor neurons.

• Why important: it helps the body respond quickly without waiting for the brain in simple reflexes.

Class 10 style definition

A relay neuron is a nerve cell that links sensory and motor neurons and helps in transmitting signals inside the central nervous system.

Reflex arc example
