The supraorbital vein is a vein of the forehead. It communicates with the frontal branch of the superficial temporal vein. It passes through the supraorbital notch, and merges with the angular vein to form the superior ophthalmic vein. The supraorbital vein helps to drain blood from the forehead, eyebrow, and upper eyelid.
The danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. [1] [2]: 345–346 Due to the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infection from the nasal area to spread to the brain, causing cavernous sinus thrombosis, meningitis, or brain abscess.
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. The two veins are joined, at the root of the nose, by a transverse branch, called the nasal arch , which receives some small veins from the dorsum of the nose.
Pott's puffy tumor can be associated with cortical vein thrombosis, epidural abscess, subdural empyema, and brain abscess. The cause of vein thrombosis is explained by venous drainage of the frontal sinus, which occurs through diploic veins, which communicate with the dural venous plexus; septic thrombi can potentially evolve from foci within ...
Flow abnormalities in smaller veins known as reticular veins or feeder veins under the skin can also cause spider veins to form, thereby making a recurrence of spider veins in the treated area less likely. Factors that predispose to the development of varicose and telangiectatic leg veins include Age
Grasping the staff made their veins pop out a bit, making them easier to find while the barbers went all Sweeney Todd. Even back then, people knew there was a limit to bloodletting, so barbers ...
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 ...
If you’re an anime or manga fan, you may recognize this symbol as the veins popping out on the forehead of someone absolutely incandescent with rage. Send to that friend who’s been bugging you ...
