The vertebral vein is formed in the suboccipital triangle, from numerous small tributaries which spring from the internal vertebral venous plexuses and issue from the vertebral canal above the posterior arch of the atlas. ... The Deep Cervical Vein (posterior vertebral or posterior deep cervical vein) accompanies its artery between the Semispinales capitis and colli. ... The diploic veins are found in the skull, and drain the diploic space. ... The cerebral veins are divisible into external and internal (internal cerebral veins) groups according as they drain the outer surfaces or the inner parts of the hemispheres. ... The Superior Cerebral Veins, eight to twelve in number, drain the superior, lateral, and medial surfaces of the hemispheres, and are mainly lodged in the sulci between the gyri, but some run across the gyri. ... The middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere, and, running along the lateral cerebral fissure, ends in the cavernous or the sphenoparietal sinus. ... The Inferior Cerebral Veins, of small size, drain the under surfaces of the hemispheres. ... The basal vein is formed at the anterior perforated substance by the union of (a) a small anterior cerebral vein which accompanies the anterior cerebral artery, (b) the deep middle cerebral vein (deep Sylvian vein), which receives tributaries from the insula and neighboring gyri, and runs in the lower part... The internal cerebral veins (veins of Galen; deep cerebral veins) drain the deep parts of the hemisphere and are two in number; each is formed near the interventricular foramen by the union of the terminal and choroid veins. ... The vein of Galen (VG), also known as the great cerebral vein, is one of the large blood vessels in the skull draining the cerebrum (brain). ... The superior cerebellar veins pass partly forward and medialward, across the superior vermis, to end in the straight sinus and the internal cerebral veins, partly lateralward to the transverse and superior petrosal sinuses. ... The inferior cerebellar veins are of large size, end in the transverse, superior petrosal, and occipital sinuses. ... The dural venous sinuses (also called dural sinuses or cerebral sinuses) are venous channels found between layers of dura mater in the brain. ... The superior sagittal sinus lies within the superior border of the falx cerebri, a two-layered dural structure separating the two cerebral hemispheres. ... The inferior sagittal sinus courses along the inferior border of the falx cerebri, superior to the corpus callosum. ... The straight sinus lies in the falx cerebri superior to the tentorium cerebelli, a bilayer of dura mater superior to the cerebellum. ... For the transverse pericardial sinus, see pericardial sinus. ... Each sigmoid sinus begins beneath the temporal bone and follows a tortuous course to the jugular foramen, at which point the sinus becomes continuous with the internal jugular vein. ... The petrosquamous sinus, when present, runs backward along the junction of the squama and petrous portion of the temporal, and opens into the transverse sinus. ... The occipital sinus courses through falx cerebelli, inferior to the straight sinus. ... The superior sagittal sinus, straight sinus, and occipital sinus connect at a series of channels that comprise the confluence of sinuses, which is found beneath the occipital protuberance of the skull. ... The cavernous sinus is a large channel of venous blood creating a sinus cavity bordered by the sphenoid bone and the temporal bone of the skull. ... The cavernous sinus receives the superior ophthalmic vein through the superior orbital fissure, some of the cerebral veins, and also the small sphenoparietal sinus, which courses along the under surface of the small wing of the sphenoid. ... The outer layer of the choroid (lamina vasculosa) consists, in part, of the larger branches of the short ciliary arteries which run forward between the veins, before they bend inward to end in the capillaries, but is formed principally of veins, named, from their arrangement, the vorticose veins. ...

The Inferior Ophthalmic Vein begins in a venous net-work at the forepart of the floor and medial wall of the orbit; it receives some veins from the Rectus inferior, Obliquus inferior, lacrimal sac and eyelids, runs backward in the lower part of the orbit and divides into two branches. ... The intercavernous sinuses are two in number, an anterior and a posterior, and connect the two cavernous sinuses across the middle line. ... The superior petrosal sinuses (or greater petrosal veins) deliver blood to the transverse sinuses, while the inferior petrosal sinuses deliver blood directly to the internal jugular veins or indirectly via the sigmoid sinuses. ... The basilar plexus (transverse or basilar sinus) consists of several interlacing venous channels between the layers of the dura mater over the basilar part of the occipital bone, and serves to connect the two inferior petrosal sinuses. ... The emissary veins are valveless veins which normally drain the intracranial venous sinuses to veins on the outside of the skull. ... The veins of the vestibule and semicircular canals accompany the arteries, and, receiving those of the cochlea at the base of the modiolus, unite to form the internal auditory veins (or veins of labyrinth) which end in the posterior part of the superior petrosal sinus or in the transverse sinus. ...
