How many bones are conterminous to the fifth

The fifth wrist bone [os trapezium], which we counted the first of the lower row, receives the capitulum of the first wrist bone in a depression carved in its upper surface, and being hollowed also on its outer side, it receives the head of the sixth bone. Thus the fifth bone is connected to two carpal bones, the first and the sixth. 44 In addition, it separately supports the first bone of the thumb [os metacarpale I] (A in figs. 1 and 2) as well.
