What does the superficial palmar artery 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.

What does the superficial palmar artery 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.
What artery supplies the superficial palmar arch?
the ulnar artery
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.
Is superficial palmar branch of radial artery?
The superficial palmar branch (SPB) of the radial artery (RA) is an important blood vessel in plastic surgery procedures of the hand. It is used as the axial artery in a free flap used for finger reconstruction. The occurrence of this arterial branch is variable, as well as its diameter and course.
What is palmaris brevis?
The palmaris brevis (PB) is a small muscle of variant morphology originating from the palmar aponeurosis to insert in the skin and fascia of the medial palm (Przystasz, 1977). The PB is uniquely innervated by the only motor component of the superficial branch of the ulnar nerve.
What is the arterial supply of the dorsum of the hand?
The radial, ulnar, and interosseous arteries provide the vascular supply of the hand and wrist. The perforators from these vessels form the basis of fasciocutaneous flaps from the forearm that are commonly used in the reconstruction of the hand. There are four dorsal metacarpal arteries.
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 is princeps Pollicis?
The princeps pollicis artery is a small muscular artery that branches from the deep palmar arch. This artery then ascends the thumb passing between two muscles. The princeps pollicis artery splits the oblique head of the adductor pollicis muscle and the first interosseous muscle.
Where M palmaris brevis is attached?
Palmaris brevis muscle is a thin, quadrilateral muscle, placed beneath the integument of the ulnar side of the hand….
| Palmaris brevis muscle | |
|---|---|
| Insertion | Palm |
| Artery | Palmar metacarpal artery |
| Nerve | Superficial branch of ulnar nerve |
Where is palmaris brevis attached to?
The palmaris brevis muscle is located on the ulnar aspect of the hand, superficial to the hypothenar muscle mass. When it contracts, it causes puckering of the skin on the ulnar border of the hand.
Where is innominate artery?
The brachiocephalic artery (or brachiocephalic trunk or innominate artery) is an artery of the mediastinum that supplies blood to the right arm and the head and neck.
How many palmar metacarpal arteries are there?
Anatomical terminology The palmar metacarpal arteries (volar metacarpal arteries, palmar interosseous arteries) are three or four arteries that arise from the convexity of the deep palmar arch.
Is the superficial palmar arch formed by the radial artery?
Introduction: The superficial palmar arch (SPA) is a major source of blood supply to much of the hand and is conventionally formed by the anastomosis of the ulnar artery with the superficial branch of the radial artery.
What is the superficial palmar branch used for?
The superficial palmar branch (SPB) of the radial artery (RA) is an important blood vessel in plastic surgery procedures of the hand. It is used as the axial artery in a free flap used for finger reconstruction.
How many palmar digital arteries are there in the thumb?
The superficial palmar branch of the radial artery gave off a proper palmar digital artery to the thumb, and two common palmar digital arteries, which supplied the thumb, index, and middle fingers. Apart from the presence of the incomplete SPA, persistent median arteries were also observed bilaterally in this cadaver.
What does the palmar digital artery anastomose with?
In the remainder, it anastomoses with the superficial palmar branch of the radial artery and the radialis indicis artery, forming a complete arch. The superficial palmar arch gives rise to the common palmar digital arteries. A separate branch provides a palmar digital artery to the lateral surface of the 5th digit 2.
