Wrist Tendinitis Anatomy
To better understand wrist tendinitis, it helps to understand the anatomy of the wrist joint.
Tendons are strong bands of tissue that connect muscle to bone. Each end of a muscle attaches to a bone. The two bones come together to form a joint. When a muscle contracts, the tendons pull on the bones, resulting in movement of the joint. Tendons are strong, but they are subject to stress from overuse and injury.
Wrist tendon anatomy includes:
The wrist is made of 10 bones: 8 carpal bones and 2 forearm bones. The carpal bones include the scaphoid, lunate, trapezoid, trapezium, hamate, capitate, triquetrum, and pisiform. The forearm bones include the radius and ulna. Ligaments hold the bones together during movement.
