The tendon
Upper part of the radius. the muscle separates into four long tendons, which descend from the forearm to the palm through the canalis carpalis and then pass to the index, middle ring, and little fingers.
At the level of the body of the proximal phalanx, each tendon splits into two parts which separate to form a gap called the hiatus tendineus.
The tendon of the deep flexor passes through the gap and crosses the other tendons (chiasma tendinum), which then attach to the palmar surface of the base of the middle phalanx. Medical Billing Training will help you to do collections and also the pending amounts from the patients.
