The frontal vein (supratrochlear vein) begins on the forehead in a venous plexus which communicates with the frontal branches of the superficial temporal vein.The veins converge to form a single trunk, which runs downward near the middle line of the forehead parallel with the vein of the opposite side.
Dural venous sinuses bordered by hard meninges (shown in blue) direct blood outflow from cerebral veins to the internal jugular vein at the base of skull. The veins of the brain, both the superficial veins and the deep venous system, empty into the dural venous sinuses, which carry blood back to the jugular vein and thence to the heart. In ...
The superficial temporal vein is a vein of the side of the head which collects venous blood from the region of the temple. [ 1 ] : 355 It arises from an anastomosing venous plexus on the side and top of the head.
primary exertional headache: throbbing, pulsatile pain which starts during or after exercising, lasting for 5 minutes to 24 hours. The mechanism behind these headaches is unclear, possibly due to straining causing veins in the head to dilate, causing pain.

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.
Extrinsic anomalies are structural changes near the Internal Jugular Vein (IJV) that can cause venous outflow obstruction. These changes can be due to bone pressure, artery pressure, enlarged lymph nodes, or an enlarged thyroid. These factors can squeeze the vein wall and block the blood flow.
