receptors are the group of cells which help us to do function in response to stimulus .
ear - It help us the hear sound.
eyes - It help us to see things around us .
Reflexes are the immediate response and is done by spinal cord through nerve impulses. It help us to protect us from sudden accident .
There are two types of reflex arcs:the autonomic reflex arc, affecting inner organs, and the somatic reflex arc, affecting muscles. When a reflex arc consists of only two neurons, one sensory neuron, and one motor neuron, it is defined as monosynaptic.
