THE FROG'H SKELETON 



\:\ 



The skeleton of the leg consists of (1) a thigh bone or fctnur, 

 (2) a lower leg bone, the tibio-fitula, formed by the united tibia 

 (great toe side) and fibula (outer side), {'.i) an ankle region 

 including the tarsal bones, two long proximal elements, and three 

 imperfectly ossified elements forming a distal row, (4) five 

 metatarsal bones, and (5) five toes, or digits the segments of which 

 are called phalanges. Note the rudimentary sixth digit, the pre- 

 hallnx, on the inner side of the first toe. 



After demonstrating to the instructor all the parts of the skele- 

 ton mentioned in the preceding paragraphs, label the same parts 

 on the proper plates.
