What is the function of the extensor digitorum?
As its name suggests, the main function of extensor digitorum is the extension of four medial fingers in metacarpophalangeal and proximal and distal interphalangeal joints. It's important to highlight that the action of this single muscle opposes the actions of two flexors of the fingers; flexor digitorum superficialis and flexor digitorum profundus. This muscle participates in the anatomy of the grip as it contributes to the opening of the hand and letting go of an object. As it crosses the wrist, the contraction of extensor digitorum participates in the extension of this joint.
Which compartment does the extensor digitorum occupy?
Along with extensor indicis, the tendons of extensor digitorum occupy the fourth extensor (dorsal) compar tment. In the dorsum of the hand the tendons of extensor digitorum run superficial to dorsal interossei muscles.
How many branches does the extendor digitorum have?
Extensor digitorum is vascularized by the branches of three different arteries;
Where does the Extensor Digitorum run?
Extensor digitorum runs from the lateral epicondyle of humerus to the medial four phalanges of the hand . In this way, it generates the pull for the extension of the four medial fingers in their metacarpophalangeal and both interphalangeal joints. Extensor digitorum also participates in the extension of the wrist.
Which nerve innervates the extendor digitorum?
Extensor digitorum is innervated by posterior interosseous nerve which is a continuation of a deep branch of radial nerve (root value C7 and C8).
Where does the muscle belly end?
At the approximately distal third of the forearm, the muscle belly ends in four tendons that enter the dorsum of the hand , passing deep to extensor retinaculum. In the hand, the tendons diverge towards the medial four fingers.
What is the proximal attachment of the extensor carpi radialis brevis
This tendon serves as a proximal attachment for extensor digiti minimi, extensor carpi radialis brevis and extensor carpi ulnaris muscles. From its origin, the muscle descends superficially down the posterior aspect of the forearm. At the approximately distal third of the forearm, the muscle belly ends in four tendons that enter the dorsum ...
Where does the digitorum run?
It runs through the fourth tendon compartment together with the extenso r digitorum, from where it projects into the dorsal aponeurosis of the index finger.
Where is the extensor digitorum communis?
The extensor digitorum indicis and extensor digititorum communis are within the 4th compartment.
Which tendons are in the flexor digitorum?
It contains tendons of the flexor digitorum superficialis and the flexor digitorum profundus, but not the flexor pollicis longus.
Which part of the body attaches to the supinator?
The upper third of the body of the bone attaches to the supinator, the flexor digitorum superficialis, and the flexor pollicis longus muscles.
Where does the digitorum run?

Where is the extensor digitorum communis?
The extensor digitorum indicis and extensor digititorum communis are within the 4th compartment.
Which tendons are in the flexor digitorum?
It contains tendons of the flexor digitorum superficialis and the flexor digitorum profundus, but not the flexor pollicis longus.
Which part of the body attaches to the supinator?
The upper third of the body of the bone attaches to the supinator, the flexor digitorum superficialis, and the flexor pollicis longus muscles.
Where does Flexor Digitorum superficialis originate?
Flexor digitorum superficialis arises at two origin points/heads: Humeroulnar head: as the name suggests, this head originates from both the medial epicondyle of humerus via the common flexor tendon, as well as the medial margin of the coronoid process of ulna.
What is the primary arterial blood supply to the Flexor Digitorum?
The primary arterial blood supply to the flexor digitorum superficialis is derived from the ulnar artery and its anterior recurrent branch. In addition to branches of the ulnar artery, the anterior and lateral surfaces of the muscle are supplied by branches of the radial artery; and its posterior surface also receives branches from the median artery.
Where does the split tendon of the flexor digitorum superficialis insert?

Where is the muscle belly located?
Its large muscular belly courses distally towards the wrist, where it splits into four tendons and attaches to the middle phalanges of the second through fifth digits of the hand. Due to their superficial location, these tendons can be easily palpated on the distal part of the forearm.
Where does the extensor digitorum muscle come from?
The extensor digitorum muscle arises from the lateral epicondyle of the humerus, by the common tendon; from the intermuscular septa between it and the adjacent muscles, and from the antebrachial fascia.
Which tendon is connected to the middle finger?
On the back of the hand, the tendons to the middle, ring, and little fingers are connected by two obliquely placed bands, one from the third tendon passing inferior and laterally to the second tendon, and the other passing from the same tendon inferior and medially to the fourth.
