The scaphoid and lunate
What are the five main ligaments of the wrist?
Capsular, Volar Radio carpal, Dorsal carpal, and collateral (radial and ulnar) ligaments
What are the intercarpal joints between the carpal bones of the wrist connected by?
Three forms of intercarpal ligaments: the four carpal bones in the proximal row, the distal row, and the carpals that connect the distal and proximal row.
What make up the intercarpal ligaments and what movement does it make?
