=====Stapes===== The stapes /ˈsteɪpiːz/ is a bone in the middle ear of humans and other mammals which is involved in the conduction of sound vibrations to the inner ear. The stirrup-shaped small bone is on and transmits these to the oval window, medially. The stapes is the smallest and lightest named bone in the human body, and is so-called because of its resemblance to a stirrup (Latin: Stapes). {{::mastoidectomy3.jpg|}} CT: [[Chorda tympani]]; I: [[Incus]]; JB: [[Jugular bulb]]; LSC: [[Lateral semicircular canal]]; M: [[Malleus]]; PSC: [[Posterior semicircular canal]]; S: [[Stape]]s; SM: [[Stapedius muscle]]; SSC: [[Superior semicircular canal]]; VIIms: mastoid segment of [[VII cranial nerve]]; VIIts: tympanic segment of VII cranial nerve.
