Radiocarpal joint
Between radius and (scaphoid, lunate and triquentrum
Radius-ulna deviation
Mostly flexion and ulna deviation
Mid carpal joint
Btn proximal and distal carpal bone
Have gliding
Mostly extension and radius deviation
Arches of hand
Traverse( proximal[fixed] and distal [adaptive])

Improve grip
Responsible for security
Fibrous flexor sheath
MCP joint
Distal phalanges
Flexor pulley system
Annular ligament
Cruciate ligament
Increases Rom
Prevent bowsting
What happens to tendons in pulley lesion with muscle contraction
They moves away from the bone
