The basal podial region, which is nearly typical in some reptiles, 

 tirodeles (Fig. 421), and man, consists of three rows of bones: a proximal 

 of three bones, a radiale or tibiale on the anterior side, an ulnare or 

 fibulare on the other, and an intermedium (not shown in the figure) be- 

 tween them. The distal row now consists of five carpales or tarsales 

 numbered from the anterior side. 



The third row is composed of one or two centrales between the other 

 rows. The metapodials (Metacarpals and Metatarsals) and the digits,
