Veins Brain Inferior

The cerebral veins are a system of veins that supply blood to the brain through the cerebral venous sinus, a capillary cavity between the main cerebral veins. The inferior cerebral veins, also known as the midbrain veins, are an important part of the cerebral venous system and are associated with poor circulation in the brain.

The inferior cerebral veins bring blood from the cerebral sinuses—the superficial and cavernous vessels—to the network of direct veins on the surface of the brain. Blood from these veins gradually flows into the straight sinus and then into the jugular vein. The inferior veins of the brain are often affected by head trauma or serious circulatory problems such as strokes or varicose veins.

The inferior cerebral venous sinus is also called the “sinus,” a terminology that associates it with the sinuses in the human cranial cavity, which is contained in the venous circulation in the region of the brain. Classification of the term "sinus" (sinus) from the Latin sinōris "in the form of a vein."

This leads to a lack of synchronous blood circulation in the brain system. The evolution of the venous system simplified blood flow during human development.

For some people who have insufficient blood flow to the sinus sinus, the superior vein cannot carry blood
