The cardinal and cranial veins are among the most important veins that carry blood to the brain. They represent two branches of the internal jugular vein - cardinal and cranial.
The cardinal and cranial veins are continuations of the posterior cerebral vein, and they transport blood from the brain to the cranial cavity through the parietal and occipital regions. The anterior and posterior cardinal veins drain blood from the cerebellum (the part of the brain that is responsible for coordinating movements) and carry it to the back of the head. The cardinal vein also supplies blood to the temporal region, including hearing, taste, vision and smell.
The cranial vein, in turn, is a continuation of the anterior cardinal vein and contains blood drained from the middle of the head and lower jaw. It connects to the posterior vein of the ear, allowing blood to flow away from the hearing organ and preventing the accumulation of fluid and pressure. Thus, the cardinal and marginal veins are important for the health of the brain and the body as a whole.
