Sartorius Muscle and Hunter's Adductor Canal (M. sartorius et 

 Canalis adductorius [Hunteri]). (Figs. 59 and 60.) 



Eemove the fascia lata from the distal two-thirds of the thigh, 

 leaving, however, the iliotibial band on the lateral surface. Clean 

 the M. sartorius carefully, watching for the nerves which are 

 near it or pass through it. Study its form, position, origin, in- 

 sertion, action, and innervation. Whence has it received its 

 name ? 



What is meant by " Hunter's canal' ' or the " adductor 

 canal" (canalis adductorius [Hunteri]) ! Note that it is the 

 continuation distalward of the lacuna vasorum. How is the

Cross-section of the right thigh through Hunter's canal, a little above the opening in the adductor 

 magnus muscle. Surface distal to the section. (After Toldt, Anat. Atlas, Wien, 1900, 2 Aufl., p. 641,

canal or tunnel formed? Study the constituents of the walls of 

 the canal. Cut through the fibrous expansion forming the ante- 

 rior wall of the adductor canal and study the contents of the 

 canal. How do the femoral vessels leave the canal to enter the 

 popliteal space? Describe the opening in the M. adductor mag- 

 nus (hiatus tendineus adductorius). At what point do the N. 

 saphenus and the A. genu suprema leave the canal? Study 1 

 lower part of the A. femoralis and its relations. Examine the 

 following branches: 



(a) Muscular rami (rami musculares). What muscles are supplied by 

 these?
