The veins puncture the relevant dural sinus, piercing the arachnoid and dura mater as bridging veins that drain their contents into the sinus. [5] The deep venous system. The deep venous system is primarily composed of traditional veins inside the deep structures of the brain, which join behind the midbrain to form the great cerebral vein (vein ...
3D model of cerebral veins. In human anatomy, the cerebral veins are blood vessels in the cerebral circulation which drain blood from the cerebrum of the human brain.They are divisible into external (superficial cerebral veins) and internal (internal cerebral veins) groups according to the outer or inner parts of the hemispheres they drain into.
The dural venous sinuses (also called dural sinuses, cerebral sinuses, or cranial sinuses) are venous sinuses (channels) found between the periosteal and meningeal layers of dura mater in the brain. [ 1 ] [ 2 ] They receive blood from the cerebral veins , and cerebrospinal fluid (CSF) from the subarachnoid space via arachnoid granulations .
The superior cerebellar veins pass partly forward and medialward, across the superior cerebellar vermis.They end in the straight sinus, [1] and the internal cerebral veins, partly lateralward to the transverse and superior petrosal sinuses.
The superior thalamostriate vein or terminal vein commences in the groove between the corpus striatum and thalamus, receives numerous veins from both of these parts, and unites behind the crus of the fornix with the superior choroid vein to form each of the internal cerebral veins.
The stria terminalis (or terminal stria) is a structure in the brain consisting of a band of fibers running along the lateral margin of the ventricular surface of the thalamus. Serving as a major output pathway of the amygdala, the stria terminalis runs from its centromedial division to the ventromedial nucleus of the hypothalamus.
The falx cerebri is a strong, crescent-shaped sheet of dura mater lying in the sagittal plane between the two cerebral hemispheres. [3] It is one of four dural partitions of the brain along with the falx cerebelli, tentorium cerebelli, and diaphragma sellae; it is formed through invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.
The superior thalamic vein (Latin: vena superioris thalami), initially called by Benno Shlesinger in 1976 the principal thalamic vein (vena principalis thalami) or centro-medial thalamic vein (vena centro-medialis thalami), also called by Russian surgeon Pirogoff internal thalamic vein (vena interioris thalami) is the most prominent vein of the thalamus.
