Superficial Palmar Arch
The Superficial Palmar Arch (pronunciation: soo-PUR-fuh-shuhl PAHL-mahr ahrch) is an important anatomical structure in the human hand.
Etymology
The term "Superficial Palmar Arch" is derived from the Latin words 'superficialis' meaning 'on the surface', 'palma' meaning 'palm', and 'arcus' meaning 'arch'.
Anatomy
The Superficial Palmar Arch is formed primarily by the Ulnar artery, with a contribution from the Superficial palmar branch of the Radial artery. It is located in the Palm of the hand, superficial to the long flexor tendons, and it typically lies more distally than the Deep palmar arch.
Function
The Superficial Palmar Arch is responsible for supplying blood to the Common palmar digital arteries, which further divide into the Proper palmar digital arteries that supply the fingers and the medial part of the thumb.
