    • n stapes In zoology and anatomy, the inmost one of the three auditory ossicles of man and other mammals, situated in the tympanum, or middle ear. The stapes is connected on the one hand with the incus, and on the other with the fenestra ovalis, and is moved by a small muscle called the stapedius. The name is derived from the close resemblance in shape of the human stapes to a stirrup. In man the bone presents a head, with a little fossa for movable articulation with the orbicular incudal bone; a neck or constricted part; two branches, legs or crura; and an oval base or foot. This bone is morphologically one of the proximal elements of the hyoidean arch. The corresponding element in birds and reptiles is very differently shaped, and is sometimes called stapes, oftener columella. It is rod-like or columellar, with an expanded base fitting the fenestra ovalis, the other end usually showing a cross-bar. Parts of such a stapes are distinguished as mediostapedial, the main shaft; extrastapedial, the part beyond the cross-bar; infrastapedial, the lower arm of the cross-bar; and suprastapedial, the upper arm of the cross-bar—the last being supposed to represent the incus of mammals. Some of these parts may be wanting, or only represented by a ligament, or coalesced with a part of the mandibular arch. The stapes or columella furnishes the primitive actual or virtual connection of the hyoidean arch with the periotic capsule. See stapedial, columella, 3
