Right temporal bone, os temporale, from below. Facies inferior pyramidis (continued). Situated almost exactly in front of the fossa jugularis is a large round opening, the foramen caroticum externum, which forms the entrance to the canalis caroticus (for the a. carotis interna, plexus venosus caroticus internus; plexus caroticus internus). This canal is curved and passes obliquely from behind and lateral- ward, forward and medianward through the pyramid, and emerges near the apex by an irre- gular opening, the foramen caroticum internum, partly on the inferior and partly on the anterior surface. Near the external carotid foramen can he seen, in the canal, the small openings of the canaliculi car otic otympanici (for the r. caroticotympanicus a. carotis internae; nn. caroticotympanici), which pass upward to the middle ear. Between the external carotid foramen, the jugular fossa and the apertura externa canaliculi cochleae lies a small depression, the fossula petrosa (for the gangl. petrosum n. glossopharyngei) with a small opening, the apertura inferior canaliculi tympanici (for the a. tympanica inferior; n. tympanicus). Situated lateral ward and projecting downward and forward is the processus styloideus (for the lig. stylomandibulare; mm. stylohyoideus, styloglossus, stylopharyngeus), variously developed in different individuals. Just behind it lies the foramen stylomastoideum (for the a. and V. stylomastoidea; n. facialis). Closely attached to the styloid process in front is seen the vagina processus styloidei (0. T. vaginal process), the lowest portion of the pars tympanica.
