The hand has high blood circulation. The arteries of the hand are ending portion of the ulnar and radial arteries which, respectively in each hand after going inside the palm create superficial and deep palmar arterial arches.
The superficial palmar arch is formed predominantly by the ulnar artery, with a contribution from the superficial palmar branch of the radial artery. However, in some individuals the contribution from the radial artery might be absent, and instead anastomoses with either the princeps pollicis artery, the radialis indicis artery, or the median artery, the former two of which are branches from the radial artery.
Alternative names for this arterial arch are: superficial volar arch superficial ulnar arch arcus palmaris superficialis arcus volaris superficialis
