Mesoscopic study on the bulbus venae jugularis superior

Abstract

Mesoscopic observations on the bulbus venae jugularis superior showed that the anterolateral wall is strongly joined to the vaginae conjuntivi of the nervi glossopharyngeus, vagus, accessorius, to the wall of the sinus petrosus inferior and to the fossa jugularis. The posteromedial wall is weakly attached to the incisura jugularis os occipitale. At the level of the inferior bony border of the foramen jugulare, the vascular wall is adhesive to the periosteum and is reinforced by fibrous septum which originate from the superior portion of the vagina carotica.
