The cavernous sinus (or lateral sellar compartment), within the human head, is a large collection of thin-walled veins〔Jonathan Dutton. Atlas of Clinical and Surgical Orbital Anatomy, 2011.ch1〕 creating a cavity bordered by the temporal bone of the skull and the sphenoid bone, lateral to the sella turcica. Relations : Superiorly : optic tract, optic chiasma, internal carotid artery Inferiorly : greater wing of sphenoid bone Medially : sella turcica and sphenoidal air sinus Laterally : temporal lobe with uncus Anteriorly : superior orbital fissure Posteriorly : apex of petrous temporal bone Structures within lateral wall : - Oculomotor nerve - Ophthalmic nerve - Trochlear nerve - Maxillary nerve - Trigeminal ganglion Structures passing through medial aspect : -Abducent nerve & Internal carotid artery Tributaries Superior ophthalmic vein Inferior ophthalmic vein Superficial middle cerebral vein Inferior cerebral vein Sphenoparietal sinus ==Structure== The sinus may be joined by several anastomoses across the midline. The cavernous sinus receives blood via the superior and inferior ophthalmic veins through the superior orbital fissure and from superficial cortical veins, and is connected to the basilar plexus of veins posteriorly. The internal carotid artery (carotid siphon), and cranial nerves III, IV, V (branches V1 and V2) and VI all pass through this blood filled space. Infection from the face may reach the cavernous sinus through its many anastomotic connections, with severe consequences. The cavernous sinus drains by two larger channels, the superior and inferior petrosal sinuses, ultimately into the internal jugular vein via the sigmoid sinus. Also drains with emissary vein to pterygoid plexus. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「cavernous sinus」の詳細全文を読む スポンサード リンク
