Document Summary
If bones independently move = more options for action. Joint located between radius, scaphoid and lunate: ligaments reinforce joint capsule. Ligaments of wrist (prevent excessive movement/bones from separating: palmar ulnocarpal ligament: from distal end of ulnar to lunate and triquetrum, radial = proximal row, ulnar = distal row, dorsal radiocarpal ligament: attached to proximal carpal row. Intrinsic = muscles start and end within hand. Joints of hand: each carpal bone will attach to adjacent ones or extend further. Intercarpal joint: carpal bones are bound by, small intercarpal ligaments (palmar and dorsal) 6-107: separates mid and proximal row of carpal bones. Joint cavity between carpal rows; separates rows: distal row = heavily attached to metacarpals, allows distal row to move freely on proximal row. Interosseous ligaments between radiocarpal (wrist; attaches radius to almost all of proximal row) joint and intercarpal joint.
