Malleus

Monday, June 4, 2012

Located in the middle ear, the malleus is a tiny bone which has the shape of a hammer. It is one of three small bones which constitute the auditory ossicles, articulating with the incus (anvil). The acoustic vibrations, coming from the outer world through the outer ear, vibrate the tympanic membrane (eardrum), setting in motion the malleus which strikes or shakes the incus, passing these vibrating waves onto the stapes (stirrup), which is in contact with the fenestra ovalis (oval window). Malleus is the Latin word for hammer.
