What is extensor digiti mini?
Extensor Digiti mini is the muscle of the rear forearm that puts on the back of the hand. The long and narrow shape extends just above the elbow to the base of a small finger. This muscle is considered to be an outer extensor of the hand, which means that the body of the muscle is located in the hand, but in the forearm, only its tendon exceeds the joint of the wrist. As the name suggests, extensor digiti mini is responsible for expanding or straightening a small finger. A common extensor tendon is a tendon that attaches several muscles of the back section of the forearm to the lateral epicondyle. When the arm is on the side and the palm is forward, this muscle is located on the side or inch side of the ARM, only on the outside of the elbow. Extensor Digiti mini starts together with Extensor Digitorum Communis, Extensor Carpi Radialis Brevis and Extensor Carpi Ulnaris muscles, all extensors of wrists and fingers.
hence muscle extensor digiti mini runs slightlyIt is obliquely down to the center of the back of the forearm and creates a small tendon just before crossing the wrist joint. This tendon goes back to the distal Radiouln joint, where the bones of the radius and the ulna in the forearm are closer to the wrist, and then passes under the dorsal carpal ligament and curvature towards the finger. The back carpal ligament is a wide, zone ligament that horizontally wraps the wrist and holds all the tendons entering the hand together.
When the tendon of the extensor digiti mini passes through the hand, it is divided into two parallel tendons, together with the first phalanx -bone, the closest of the three small bones form a small finger. Just before they inserted on Falang, a small part of the tendon of the extensor digitorum communis of the muscles, known as the extensor expansion, which exceeds obliquely just below the ring to get closer. Together they are attached to the base of the first phalanx on the dorsal or back. This place of attachment means that any contraction of extensorDigiti mini is pulled up and backwards on a small finger and extends the entire number of the rear.
