Tendons are fibrous cords that are similar to a rope, attached to muscles and bone. The tendons that control movement in your hands, wrists and fingers run through your forearm. There are 6 tendons that help move your wrist. The wrist tendons are:
- Flexor carpi radialis: This tendon is one of two tendons that bend the wrist. It attaches to the base of the second and third hand bones. It also attaches to the trapezium, one of your wrist bones.
- Flexor carpi ulnaris: This is the other tendon that bends the wrist. It attaches to the pisiform, another wrist bone, and to the 5th hand bone.
- Palmaris longus tendon: This tendon is unique because only 3/4 of the population has it. For those who do have it, it can vary in size. It is, however, a tendon you can live without because it has very little function in the hand and wrist. This tendon is often used to repair other tendons since it serves such a small purpose.
