👉 The term "atrabial" is used in medicine to refer to a specific type of blood vessel, also known as an arteriole or arteria. It's the primary blood vessel that carries oxygenated blood from the heart and other parts of the body to the rest of the body, including the brain. The arterial walls are lined with smooth muscle cells called smooth muscle cells (also known as myocytes), which help regulate blood flow in the arteries.
