ABDOMINAL MUSCLES. 



The fascia lata of the thigh is connected with the external 

 or lower edge of Poupart's ligament, in its whole extent : this 

 is called the sartorial portion. 



— The fascia lata may here be considered as divided into two 

 layers : 1st, The sartorial. 2d, The pectineal which contin- 

 uous above and without, as seen in fig. 83, is reflected behind

the sheath of the vessels, and over the anterior surface of the 

 pectineus muscle up to the spine of the pubis. The sheath of 

 the femoral vessels is formed by an extension downwards of 

 the fascia trans versalis and fascia iliaca for about an inch and 

 a half between these layers of the fascia lata. — And there is

 part's ligament, 2, 2. The upper or sartorial portion of the fascia lata, attached 

 along the margin of the crest of the ilinm, and along Poupart's ligament, as far 

 as the spine of the os pubis (3). 4. The pubic or pectineal portion of the fascia 

 lata, continuous at 3 with the iliac portion, and passing outwards behind the 

 sheath of the femoral vessels to its outer border at 5, where it divides into two 

 layers ; one is continuous with the sheath of the psoas (6) and iliacus (7) ; the 

 other (8) is lost upon the capsule of fhe hip-joint (9). 10. The femoral nerve, 

 enclosed in the sheath of the psoas and iliacus, 11, Gimbernat's ligament. 

 12. The femoral ring, within the femoral sheath. 13. The femoral vein. 14. 

 The femoral artery : the two vessels and the ring are surrounded by the femo- 

 ral sheath, and thin septa are sent between the anterior and posterior wall of 

 the sheath, dividing the artery from ihc vein, and the vein from the femoral
