Q5.C.Hair cells -They are the basic unit of hair cells
Explanation:They are two types inner and outer hair cells which have different roles for sensory transduction
Inner hair cells:These are primary sensory cells which cause generation of action potential
Ouer hair cells:These are cochlear amplifier,which cause the movement of basilar membrane and increases the amplitude and sharpness of sound
