Flexor digitorum profundus muscle

The flexor digitorum profundus (Latin for " deep finger flexors " ) is one of the skeletal muscles in the deep ( III.) Beugerschicht of the forearm. Just as the flexor digitorum superficialis he divides into four terminal tendons that run through the carpal tunnel. This draw around the center joints of the fingers by the aufgegabelten tendons of the flexor digitorum superficialis. They also serve the Musculi lumbricales as the origin.

In humans, the muscle arises exclusively to the ulna.

In the four-footed mammals of the muscle has three muscle origins, three heads:

  • Humeral head: originates at the medial epicondyle of the humerus
  • Caput radial: originates on the radius
  • Caput Ulna: originates on the ulna

Function
