THE NECTURUS 33 



Femoro-metatarsalis 



There are three muscles on the dorsal face of the foot. 

 The median of these is the femoro-metatarsalis. Note the 

 origin and follow the muscle to the insertions between the 

 metatarsals. Note how it is split to serve the tarsals. (A 

 deeper slip is seen with further dissection.) 



Extensor tibialis 



The anterior of the three muscles is a heavy structure. 

 To see this muscle it is necessary to remove the femoro* 

 metatarsalis from its origin. 



Extensor tibialis profundus 



With the removal of the femoro-metatarsalis this slip is 

 seen. Note the origin and insertion. 



Extensor fibularis 



It is completely covered by the deep slip of the femoro- 

 metatarsalis. With this dissected away it is plainly seen. 



Supinator 



This small muscle originates on the fibula, distal to the 

 extensors, and extends diagonally across the tibia. 



MUSCLES OF THE SOLES OF THE FEET 



Plantar superficialis 



This is a short, heavy muscle that originates on the 

 femur, extends distally and blends with the fascia of the 

 sole of the foot. Determine the origin, cut through at the 

 distal end of the muscle and deflect to see the muscular 

 elements underneath.
