Flexor digitorum (deltoid muscle): anatomy, innervation, functions
**Flexor digitorum** is a thick and short muscle that lies on the back of the hand from the base of the thumb to the tips of the fingers. It separates the distal and proximal phalanges of the finger, which are located in the posterior and anterior parts of the tendon, respectively.
It is most developed in humans (on the left), as well as in humans as a result of its evolutionary transformations. This adaptation has allowed him to more confidently operate the device, whether he is drawing and working on a typewriter or serving food.
The flexor of the fingers, the deep flexor, is a muscle located in the inner surface of the wrist and is responsible for the movement of the thumb and the phalanges of the index and middle fingers. It has a rich network of blood supply and nerves, so damage to it can cause serious problems with mobility and sensation. In this article we will look at the main functions and anatomical structure of the flexor digitorum profundus.
The flexor of the fingers - deep bend - is a muscular element of the inner covering of the hand. This name corresponds to its anatomical location - deep inside the organ. In human language the word is translated as “deep flexor.” Abbreviation - p. p.k.g. Anatomical purpose - the location of the muscle tissue of this organ is determined by its functions. As we have already said, the deep muscle layer is responsible for performing actions such as: 1. raising the thumb joint higher (when the hand is in a position above the knee); 2. bringing together the phalanges of the three thumbs; 3. performing the final movement of the large bone after the preceding phalanx (the higher the ascents and the lower the descents, nevertheless, the more correct and natural the appearance of the organs).
