Where does superficial palmar arch supply?

Where does superficial palmar arch supply?

The main function of the superficial palmar arch is to provide blood supply to the phalanges, metacarpophalangeal and interphalangeal joints of digits 2-4. It does so via its three branches called the common palmar digital arteries. This article will discuss the anatomy and function of the superficial palmar arch.

Which arteries are superficial and deep palmar arches?

The deep palmar arch (deep volar arch) is an arterial network found in the palm. It is usually primarily formed from the terminal part of the radial artery. The ulnar artery also contributes through an anastomosis. This is in contrast to the superficial palmar arch, which is formed predominantly by the ulnar artery.

What forms superficial palmar arterial arch?

Anatomical Parts The superficial palmar arch (superficial volar arch; arcus volaris superficialis) is formed by the ulnar artery, and is usually completed by a branch from the a. volaris indicis radialis, but sometimes by the superficial volar or by a branch from the a. princeps pollicis of the radial artery.

How many palmar arches are there?

Hand has derived its arterial supply, from two anastomotic arches, superficial and deep palmar arches which are formed between two main arteries of forearm i.e. radial, ulnar and their branches, in the palm.

What is the function of the superficial palmar arch?

The superficial palmar venous arch is located in the hand, and assists in draining oxygen-depleted blood from the hand and the common palmar digital veins within the fingers. From there, blood drains through the arch and up the ulnar vein.

What does the deep palmar arch supply?

The main function of the deep palmar arch is to provide blood supply for the bones, joints and deep muscles of the hand. These muscles include: adductor pollicis, dorsal interossei, palmar interossei, and lumbrical muscles. Additionally, it supplies the radiocarpal joint via its recurrent branches.

What muscles does the deep palmar arch supply?

How is deep palmar arch formed?

The deep palmar arch (arcus volaris profundus; deep palmar arch) is formed by the anastomosis of the terminal part of the radial artery with the deep pallmar branch of the ulnar.

What is a superficial palmar arch?

The superficial palmar arch originates as the terminal branch of the ulnar artery, distal to the flexor retinaculum 1. It is located superficial to the long flexor tendons of the digits and deep to the palmar aponeurosis. The superficial palmar arch travels distally, then laterally across the metacarpals.

What is a complete palmar arch?

: either of two loops of blood vessels in the palm of the hand: a : a deeply situated transverse artery that is composed of the terminal part of the radial artery joined to a branch of the ulnar artery and that supplies principally the deep muscles of the hand, thumb, and index finger.

What does deep palmar arch supply?

What are common palmar digital arteries?

Three common palmar digital arteries arise from the convexity of the superficial palmar arch and proceed distally on the second, third, and fourth lumbricales muscles. Alternative names for these arteries are: common volar digital arteries, ulnar metacarpal arteries, arteriae digitales palmares communes, or aa.
