These tendons, along with those of flexor digitorum profundus, are enclosed by a common flexor sheath. The tendons attach to the anterior margins on the bases of the intermediate phalanges of the four fingers. These tendons have a split (Camper's Chiasm) at the end of them through which the tendons of flexor digitorum profundus pass.
The superficial muscles have their origin on the common flexor tendon. [2] The ulnar nerve and artery are also contained within this compartment. [2] The flexor digitorum superficialis lies in between the other four muscles of the superficial group and the three muscles of the deep group. This is why it is also classified as the intermediate ...
The deep flexor attaches to the distal phalanx, and the superficial flexor attaches to the middle phalanx. The flexors allow for the actual bending of the fingers. The thumb has one long flexor and a short flexor in the thenar muscle group.
the flexor digitorum profundus acting on the proximal and distal joints, and the flexor digitorum superficialis acting on the proximal joints mainly by the lumbricals and interossei, the long extensors having little or no action upon these joints thumb the flexor pollicis longus: the extensor pollicis longus

Annular and cruciform parts of fibrous sheath over (synovial) flexor tendon sheaths. Insertion of flexor digitorum profundus tendon. Insertion of flexor digitorum superficialis tendon. Midpalmar space (deep to flexor tendons and lumbrical muscles). 5th finger (synovial) tendinous sheath. Common flexor sheath (ulnar bursa). Hypothenar muscles.
It contains tendons of the flexor digitorum superficialis and the flexor digitorum profundus, but not the flexor pollicis longus. [2] The sheath which surrounds the flexor digitorum extends downward about halfway along the metacarpal bones, where it ends in blind diverticula around the tendons to the index, middle, and ring fingers.
For patients with low median nerve palsy, it has been shown that the flexor digitorum superficialis of the long and ring fingers or the wrist extensors best approximate the force and motion that is required to restore full thumb opposition and strength. This type of transfer is the preferred method for median nerve palsy when both strength and ...
