Basic skeletal anatomy

You are wrong about the wrist. The wrist is called carpus. And is made up of the carpal bones. Carpals bones are definitely NOT fingers. Fingers consist of phalanges, namely; distal, intermediate and proximal phalanges. (I know less about the ankle but the talus together with the tarsal bones is called the tarsus. Again; the tarsal bones are definitely NOT the toes...The toes like fingers consist of the following phalanx bones; distal, middle/intermediate and proximal. (both big toe and thumb do not have the intermediate phalanx)

PS: radio-ulna I believe is where the radio and ulna meet (not the arm and the hand) and is/can be situated both near the wrist as well as the elbow. It is simply where the two bones of the lower arm touch eachother.
