The muscle belly divides into 4 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.

Simply so, what tendons are in your hand?
extensor tendons – which run from the forearm, across the back of your hand to your fingers and thumb, allowing you to straighten your fingers and thumb. flexor tendons – which run from your forearm, through your wrist and across the palm of your hand, allowing you to bend your fingers.

- An open injury, such as a cut, on the palm side of your hand, often where the skin folds as the finger bends.
- An inability to bend one or more joints of your finger.
- Pain when your finger is bent.
- Tenderness along your finger on the palm side of your hand.

How many flexor tendons are in the hand and where do they attach?
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.

X-rays do NOT show tendons, ligaments, nerves, cartilage or blood vessels. X-rays typically show bones and joints, and may, at times, show the absence of skin (e.g. infection). If the patient's x-rays are normal, and the bone scan is positive in the area of pain, there is a strong possibility of a fracture.Can tendons grow back?

Dupuytren's contracture is an abnormal thickening and tightening of the normally elastic tissue beneath the skin of the palm and fingers.

When tendon damage occurs, movement may be seriously limited. The damaged area may feel weak or painful.What happens if a torn tendon is not repaired?
