The flexor digitorum superficialis muscle ( Latin for "superficial finger flexor") or flexor digitorum sublimis muscle is a skeletal muscle and represents the middle layer of the flexors on the forearm . It is divided into four tendons that run through the carpal tunnel . They split into two reins just before their approaches. The tendons of the flexor digitorum profundus muscle run through the resulting gaps.
In humans, the muscle has two heads :
- Caput humeroulnare (humerus-ells-head)
- Caput radiale (spoke head)
function
The flexor digitorum superficialis muscle flexes the elbow , the hand in the wrist and the 2nd to 5th fingers to the middle phalanx.
