The term "arteria metacarpea dorsalis" refers to an anatomical structure found in the human body. It is derived from medical Latin, where "arteria" means artery, "metacarpea" refers to the metacarpal bones (the bones of the hand between the wrist and the fingers), and "dorsalis" signifies the dorsal side or the top surface.
The arteria metacarpea dorsalis is a specific artery located on the dorsum (back) of the hand. This artery arises from the radial artery, one of the main arteries in the forearm. The radial artery travels down the forearm and enters the hand, where it gives rise to the arteria metacarpea dorsalis.
Its primary function is to supply oxygenated blood to the surrounding tissues and structures on the back of the hand, including the metacarpal bones, tendons, muscles, ligaments, and skin. The arteria metacarpea dorsalis branches into smaller blood vessels to ensure an adequate blood supply and nourishment to these areas.
Understanding the anatomy and physiology of the arteria metacarpea dorsalis is vital for healthcare professionals, such as surgeons, anatomists, and radiologists. This knowledge helps in diagnosing and treating various conditions, such as traumatic injuries, arterial diseases, and malformations affecting the blood supply to the dorsal side of the hand.
