The five senses of the human body are:
Taste: its receptors are chemoreceptors located in the tongue, named taste buds
Smell: its receptors are also chemoreceptors, located in the nose, named Olfactory receptors
Hearing: cochlea are tonoreceptors which feels the vibrations in the air that produces the sound and transmit it to the brain
Touch: its receptors are terminal nerves mechanoreceptors, located everywhere in the body
Sight: The retina contains photoreceptors which transmit the nerves impulses to the brain
