34 THE NECTURUS 



Plantaris profundus 



With the deflection of the superficial plantar, this large 

 muscle is seen extending diagonally across the foot. Note 

 the relation of this muscle to the superficial slip. 



Cut through the plantaris profundus and identify the 

 two muscles that are seen extending under it. 



FlBULARIS TARSALIA 



This is a small, thin muscle that originates on the fibula 

 and is inserted on the tarsalia. Locate the points on the 

 skeleton of the foot. 



Pronator 



A large, triangular muscle extends from the fibula, to 

 the tibia and serves as a pronator. 



Some of the smaller muscles of the foot and toes have 

 been omitted. 



After the other organs have been studied and drawn, 

 remove the pelvic girdle and study the musculature that 

 belongs strictly to this structure. This will give the con- 

 nections between the girdle and skeleton and between the 

 girdle and legs.

 of this muscle is apparent extending to the midline of the
