external definition

One of two element that constitute the basal row of carpals. It articulates proximally with the radius, mesially with the ulnare (or pars intermedia of the ulnare when the ulnare is fused to the intermedium) and distally with the centrale (also recognized by some authors as element Y). This element originates from one or two condensation centers. Occasionally it may fuse to carpal 5(4), the ulnare, or other elements.[AAO]

terminology notes

In reptiles, birds, and amphibians, this bone is instead commonly referred to as the radiale, because of its articulation with the radius[WP]
