Ligaments lateral Function?

Function? Ligaments ant. & post. Palmar carpal ligaments Dorsal carpal ligaments c Figure 1a.(a) Schematic shows the palmar carpal ligaments (frontal view). 1 = radioscaphocapitate (RSC) ligament, 2 = radiolunotriquetral (RLT) (long radiolunate) ligament, 3 = radioscapholunate ligament, 4 = palmar ulnotriquetral ligament, 5 = ulnolunate ligament, 6 = proximal and distal bands of the palmar scaphotriquetral ligament. The thick black line along the distal surface of the ulna represents the palmar radioulnar ligament. (b) Schematic shows the dorsal carpal ligaments (frontal view). 7 = dorsal scaphotriquetral ligament, 8 = dorsal radiotriquetral ligament, 9 = dorsal ulnotriquetral ligament, 10 = radial collateral ligament. Thick black line represents the dorsal radioulnar ligament. c Function?
