Extensor digiti minimi tendon: Positioned directly over the distal radioulnar joint. Extensor digiti minimi usually has double tendon [2] in the fifth compartment upon inserting onto the little finger Vaughn-Jackson syndrome: 6 Extensor carpi ulnaris tendon: The tendon runs within the groove of ulnar head Extension and adduction of wrist ...
Brevis moves the arm from ulnar abduction to its mid-position and flexes dorsally. Longus is a weak pronator in the flexed arm and a supinator in the outstretched arm. At the carpal joints longus acts in dorsiflexion with the extensor carpi ulnaris and in radial abduction with the flexor carpi radialis. These two muscles are called "fist ...
In the early stage of development, the extensor precursor divides into 3 layers namely, superficial layer, radial layer and deep layer. [5] [6] The superficial group develops to become the extensor digitorum communis, the extensor carpi ulnaris and the extensor digiti minimi. The radial layer forms the extensor carpi radialis longus, the ...
The intrinsic muscle groups are the thenar and hypothenar (little finger) muscles; the interossei muscles (four dorsally and three volarly) originating between the metacarpal bones; and the lumbrical muscles arising from the deep flexor (and which are special because they have no bony origin) to insert on the dorsal extensor hood mechanism.

The extensor carpi radialis longus (ECRL) has the most proximal origin of the extrinsic hand extensors. It originates just distal to the brachioradialis at the lateral supracondylar ridge of the humerus, the lateral intermuscular septum, and by a few fibers at the lateral epicondyle of the humerus. [1]
The extensor carpi ulnaris extends the wrist, but when acting alone inclines the hand toward the ulnar side; by its continued action it extends the elbow-joint. The muscle is a minor extensor of the carpus in carnivores, but has become a flexor in ungulates. In this case it would be described as ulnaris lateralis.
The lateral border (radial side) is a pair of parallel and intimate tendons, of the extensor pollicis brevis and the abductor pollicis longus. [2] Accordingly, the anatomical snuffbox is most visible, having a more pronounced concavity, during thumb extension .)
