Fig. 15. Drawings of a reconstruction of the stapes in a 275 mm

(30 week) fetus (Wisconsin series 4) ; X 7: (a) the reconstruction entire, viewed from above (superior, or cranial, aspect); (b) the neck and adjacent portions of the crura, in lateral (tympanic) view; (c) the base of the ossicle seen in medial (vestibular) view.

The stapes has attained adult form; of the crura, now deeply channeled, the posterior is longer and larger (as); the base is flatter on the posterior than on the anterior margin (c) ; the head and neck are hollowed (b). In this fetal specimen, as in some adult ossicles, a ledge of bone partially closes the space of the neck toward the obturator foramen.
