Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System

Explanation:

These receptors are located all over the body but some types of receptors are in specific areas of the body (e.g. taste receptors in the mouth).

Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System (i.e. the brain and spinal cord, sometimes referred to in the abbreviated form: C.N.S.). This is happens because peripheral nerves all connect to the spinal cord via the network of nerves within the nervous system.

The information so received by the C.N.S. is further transmitted by relay neurone(s) with the C.N.S.
