Malleus is hammer shaped ear ossicle found attached with tympanic membrane laterally and with incus bone medially. Organ of Corti exhibits hair cells which act as auditory receptors. Scala media is filled with endolymph whereas scala vestibuli and scala tympani are filled with perilymph. Vestibular apparatus maintains balance of the body.
