Fig. 275. — Ventral view of skinned frog showing superficial muscles on the 

 animal's right and deeper muscles on the left. Some connective tissue and the 

 m.ylohyoideus have been cut away on both sides, and on the left the following 

 muscles have been removed wholly or in part : geniohyoideus ; depressor 

 mandibularis ; deltoideus ; dorsalis scapulae ; pectorales anterior medius and 

 posterior ; extensor cruris ; sartorius ; gracilis ; semimembranosus. The 

 adductor femoris and semitendinosus have been reflected. Exposed or nearly 

 exposed bone and cartilage are shown by mechanical stippling. — From Saunders 

 and Manton, A Manual of Practical Vertebrate Morphology, 2nd edition.
