Ulnar Artery
By : Sedra MuhammedIntroduction:
The ulnar artery (alongside the radial artery) provides vascular supply to the forearm and hand (both muscles and bones), it has six branches and arises at the cubital fossa and corsses through the medial side of the forearm,
It ends in the medial part of the hand as the Superficial palmar arch.
Along its course it’s accompanied by the ulnar veins.
The ulnar nerve lies medial to the ulnar artery.
It ends in the medial part of the hand as the Superficial palmar arch.
Along its course it’s accompanied by the ulnar veins.
The ulnar nerve lies medial to the ulnar artery.
Origin:
It arises from the brachial artery as the largest terminal branch, at the level of cubital fossa ( where the brachialis muscle lies beneath it).
Course:
• After rising it passes inferomedially then it continues inferiorly on the medial aspect of the forearm.
The following structures lie above the Ulnar artery:
- Biciptal aponeurosis.
- Flexor digitorum superficialis m.
- Flexor carpi radialis m.
- Pronator teres m.
- Palmaris longus m.
- Median n.
- Biciptal aponeurosis.
- Flexor digitorum superficialis m.
- Flexor carpi radialis m.
- Pronator teres m.
- Palmaris longus m.
- Median n.
the Ulnar artery lies superficial to the following muscles:
- Flexor digitorum profundus.
- Brachialis.
- Flexor digitorum profundus.
- Brachialis.
• As it travels downward in the forearm it passes between Flexor digitorum superficialis and Flexor carpi ulnaris.
• It enters the hand superficial to the Flexor retinaculum through Guyon’s canal with The Ulnar nerve
It gives a deep branch which goes on to form the deep palmar arch,
Then the ulnar artery continues superficialy to form the superficial palmar arch.
Then the ulnar artery continues superficialy to form the superficial palmar arch.
Branches:
The Ulnar artery gives six branches,
They can be remembered by the following mnemonic:
Anatomical Pictures Can Definitely Deeply Please.
1. Anterior ulnar recurrent.
2. Posterior ulnar recurrent.
3. Common interosseous.
4. Dorsal carpal branch.
5. Deep palmar branch.
6. Palmar carpal branch.
