What is Flexor Digitorum Superficialis?
Flexor Digitorum Superficialis is the muscles contained in the front section of the forearm located on the palms of the arm. Of the eight found muscles, five are considered a superficial layer or near the skin and three are in a deep layer or near the bone. Because this muscle is so deep in the surface layer, it is sometimes classified as a transitional muscle of the forearm and is a flexor of four fingers and wrists. The forearm, Flexor Digitorum superficialis have two heads or sections, and therefore two points of origin. Humeroulnar's head, sometimes considered two separate heads, originated in the media epicondyle humerus, one of the two rounded bone protrusions at the base of the humerus at the top, as well as on the coronoid process of the ulna found at the top of the ulna bone in the forearm just below the elbow. Both are located on the middle side of the arm, closest to the body when the palm is facing forward. Its radial head comes from the front surface of the bone of the radius in the forearm, just below the elbow.
of these points of origin Flexor Digitorum Superficialis runs down the front forearm and forms four tendons - one for each of the four fingers - which passes through the tunnel of the carpal tunnel. The carpal tunnel is a narrow channel between the carpal bones in the wrist, through which these and several other tendons, as well as the middle nerve, to achieve their attachment in their hand. After passing through the carpal tunnel tunnel, these specific tendons are attached to the bases of the middle bones of Phalang in four fingers on their front sides. The main feature of Flexor Digitorum Superficialis is the twisting of the fingers inside towards the palm at the large joint in the middle of the fingers, the proximal interphalangal joint. Other forearm flexors also help when the wrist ripple when the fingers are first curled in.
As Flexor Digitorum Superficialis is involved in forearm flexion and has tendons in the carpal tunnel, excessive use of this muscle can contribute to the syndromecarpal tunnel. Recurrent tension on the tendons of these muscles, where they pass through the carpal tunnel, as in the bending of wrists and fingers to write on the keyboard, can cause swelling, inflammation and subsequent enlargement of these tissues. Such tendon enlargement can lead to the compression of the middle nerve, which also passes through the carpal tunnel and shakes the hand, and subsequent pain, armor and numbness associated with this condition.
