Note that these two septa divide the thigh into two great 

 osteofascial compartments, one in front, the other behind. The 

 latter is further subdivided by a layer of fascia, sometimes called 

 the * ' posterior intermuscular septum. ' ' The further dissection 

 will reveal the following contents of these osteofascial compart- 

 ments. (Fig. 57.)

Cross-section of right thigh, a little above its middle. Surface distal to the cut. (After Toldt, 

 Anat. Atlas, Wien, 1900, 2 AufL, p. 640, Fig. 1020.) 



(1) In the anterior osteofascial compartment (in front, between the me- 



dial and lateral septa) the extensor muscles and the femoral nerve. 



(2) In the posterior osteofascial compartment (behind, between the medial 



and lateral septa), 



(a) Between the lateral and posterior septa, the flexor muscles and 



the great sciatic nerve. 



(b) Between the medial and posterior septa, the adductor muscles 



and the obturator nerve. 



Sheath for Femoral Vessels and Femoral Canal. 



Before proceeding to this dissection, the student should study 

 thoroughly, on a dry preparation of the pelvis with its ligaments, 

 the following : 



(a) Inguinal ligament of Poupart (Lig. inguinale [Pouparti]}. 



(b) Lacunar, ligament of Gimbernat (Lig. lacunare [Gimbernati] ). 



After this, divide the cornu superius of the margo falci- 

 formis of the fossa ovalis and carry the knife lateralward just
