Hearing receptors: Inside the ears there is a small structure known as cochlea which contains the organ of corti which further contains the hair cells [sensory cells] working as hearing receptors but research till date concludes that mammalian cochlear hair cells do not regenerate, either spontaneously or after damage.
Taste receptors: The small little bumbs present of our tongue are known as papillae whioch functions as taste receptors as they contain taste buds. Scientifically there taste buds die off and regenerate every few weeks.
Olfactory receptors: These receptors keep on replacing due to continuous differentiation of basal cells which develop and are capable of restablishing the connection with Central nervous system.
