Full Answer
Flexor tendons run from the forearm to the ends of the fingers across the palm side of the hand. They control the ability to bend fingers down to the palm (for example to make a fist, grip, or pinch objects). When these tendons are cut or injured, it can be impossible to bend the fingers or thumb.
Flexor digitorum profundus (FDP) tendons They run down the forearm and within the carpal tunnel. The four tendons glide in sheaths along the hand and fingers and insert into the fingertip bone. These tendons run closer to the bone compared to the rest of the flexors in the hand and fingers.
The flexor tendons are strong smooth cords that connect the muscles of the forearm to the bones in the fingers and thumb. There are two to each finger and one for the thumb (See diagram). The tendons run inside tunnels at the wrist and in the fingers, and they bend your fingers in the manner of a bicycle brake cable.

The flexor digitorum superficialis [FDS] and flexor digitorum profundus [FDP]) originate proximally in the forearm, at the medial epicondyle of the elbow. They, along with flexor pollicis longus (FPL) and the median nerve, travel through the carpal tunnel at the wrist and enter the palmar surface of the hand.

If you bend it down and hold it for me I can prove that FDP is not having any action there because it is completely slack at the DI p joint.
Flexor tenolysis is a surgical procedure used to remove adhesions that inhibit active flexion of digits. [1, 2, 3] Normal active tendon function requires that flexor tendons be able to glide smoothly within their tendon sheath.
flexor tendons, nine long tendons which pass from the forearm through the carpal tunnel of the wrist. They diverge in the palm, where two go to each finger (one attaches at the DP and one at the MCP) and one goes to the thumb.
Zone I is distal to the FDS insertion, zone II between the FDS insertion and beginning of A1, zone III in the palm, zone IV under the transverse carpal ligament, and zone V proximal (Verdan C: Primary repair of flexor tendons.
