. Bensley's Practical anatomy of the rabbit : an elementary laboratory text-book in mammalian anatomy. Rabbits -- Anatomy. 18G ANATOMY OF THE RABBIT m-so. stylomastoid foramen lies between the latter and the external acoustic meatus. The petrous portion, as viewed from its medial surface, is roughly oblong; it is placed obliquely with reference to the basi- occipital and basisphenoid. The parafloccular fossa occupies its posterodorsal portion, and extends into the substance of the bone, forming a much larger depression than is indicated by the diameter of its rim. The related dorsal margin of the bone is occupied by a groove which leads into a canal at its posterior margin. It indicates the position of the lateral portion of the transverse sinus of the dura mater. The ventral, thicker portion of the bone, enclosing the apertures of the internal acoustic meatus and the facial canal, is also that lodging the vestibulum and cochlea of the internal ear. A small aperture at its anteroventral angle, visible only when the petrotympanic is freed from its connections, represents the hiatus canalis facialis of the human skull. It transmits the great super- ficial petrosal nerve, a branch of the facial nerve passing to the sphenopalatine ganglion. The tympanic surface of the petrous portion is described be- low in connection with the struc- tures of the tympanic cavity. The tympanic portion forms the spherical, expanded, shell- like, tympanic bulla, which con- tains in its interior the tympanic cavity, and is continuous dorsally with the bony enclosure of the external acoustic meatus. The boundary between the two is indicated externally by a shallow oblique groove, the position of which indicates roughly that of the tympanic membrane within. The medioventral margin of the bone is articulated with the basioccipital, but the swollen portion is separated from the latter by a broad groove terminating 7n-ae. Fig. 90.
