颅内静脉窦为接受来自脑实质、脑膜、迷路、颞骨、眶部以及颅骨板障等处血流之粗大集合静脉。此等静脉窦或在硬脑膜、大脑镰、小脑天幕的裂层之中,或在脑膜颅骨附着处,其中最大者为横窦,此静脉窦自枕内粗隆起,顺水平方向延伸至天幕后部附着处,折行向下,进入乳突内侧面的一个深弯沟,成为乙状窦,止于颈内静脉窦。它从海绵窦、岩骨、蝶骨体和枕骨引导血液至颈静脉球,由此垂直下行,是为颈内静脉。
Intracranial sinus to accept from the brain parenchyma, meninges, labyrinthine, temporal bone, orbital and skull plateau and other blood flow in the coarse collection of veins. The sinus or in dura mater, sickle, cerebellar rupture of the skull, or in the attachment of the skull, the largest of which is the transverse sinus, the sinuses from the occipital protuberance, along the horizontal extension to the sky behind Ministry of attachment, the line down, into the mastoid medial side of a deep curved ditch, into the sigmoid sinus, ending in the jugular vein. It guides the blood from the cavernous sinus, the petrous bone, the sphenoid body and the occipital bone to the jugular bulb, thus vertically downwards, for the jugular vein.
