Veins of bones, nutritive or bony (from Latin os - bone, Greek νεώς κενὸς - thin bone) - are a branch of the lateral internal thoracic artery, namely its upper access.
The veins of this area are named by analogy with the veins of other parts of the body and the anatomical names of the surfaces or structures of bones. Therefore, they received the same name as the arteries.
The bony veins supply blood to the lateral parts of the occipital bone, the temporal and parietal bones of the skull from the deep parts of the venous system. In addition, they play a significant role in the metabolism within bones and provide nutrition to bone tissue. These veins also improve blood circulation in the lower jaw. Venous blood transports metabolic products, plasma proteins and other substances from bone tissue to other organs.
