====Metacarpals and Metatarsals====
The arrangement of the metatarsals are similar to those of the metacarpals in that they are rod shaped bones, numbered from I to V. The 1st is the most medial and is very small, the 3rd and 4th are the longest. The proximal base of each articulates with it's corresponding carpal bone and the adjacent metacarpal. The distal end is it's head, which is transversely cylindrical and articulates with the proximal phalanx. Metacarpals II - V possess a sagittal ridge on their palmar aspects.

====Phalanges====
* Proximal phalanx - of the main digits (II - V) they have a concave articular surface proximally. The palmar border has a groove to accomodate the articular surface of the metacarpus when the joint is fixed. The distal head has two convex areas seperated by a groove.
