Deep Palmar Arch

Friday, August 12, 2011

The deep palmar arch of arteries is formed mainly from the deep branch of the radial artery and the deep palmar branch of the ulnar artery (the superficial palmar arch is formed predominantly by the ulnar artery). Giving off to the palmar metacarpal arteries, the deep palmar arch is located on the metacarpal bones bases and on the interossei of the hand. The Deep palmar arch is covered in front by all the nerves, tendons, and muscles of the palm of the hand except by the interosseous muscles, which, together with the metacarpal bones, lie behind it.
