go THE POCKET ANATOMY 



Anastomotic : (i) to pit of great trochanter (digital anas- 

 tomosis], supplies external rotators ; anas, gluteal, ascending 

 of internal circumflex, and (2) to crucial anastomosis; anas. 

 first perforating, internal and external circumflex. 



Articular : to capsule of hip-joint. 



THE GLUTEAL ARTERY. 



Largest branch of internal iliac, passes outwards between 

 lumbo-sacral cord and ist sacral nerve, escapes from pelvis 

 above pyriformis, divides immediately into superficial and 

 deep branches. 



Superficial branch : runs between the two larger glutei, sup- 

 plying gluteus maximus ; anas, sciatic and internal circumflex. 



Deep branch : goes between two smaller glutei, subdivides 

 into two : 



Superior division : goes to anterior superior iliac spine ; anas. 

 circumflex iliacs, ascending branches of external circumflex. 



Inferior division : supplies gluteal muscles, and descends to 

 great trochanter ; anas, external circumflex. 



Nutrient branch : enters hip-bone just as artery emerges 

 from pelvis. 



THE FEMORAL ARTERY. 



Extent. From Poupart's ligament to the opening in the 

 adductor magnus. 



Course. Thigh being abducted and rotated out, a line 

 drawn from point midway between symphysis pubis and 

 anterior superior iliac spine to most prominent part of in- 

 ternal condyle of femur, will in upper rd give course. 



Relations. Superficial in upper rd, being contained in 

 Scarpa's triangle, -more deeply placed in middle Jrd (Hunter's 

 canal). In first i^ inches is enclosed in femoral sheath. 



In front. Skin, superficial and deep fascia, internal cutane- 

 ous branch of anterior crural nerve, sartorius, long saphen- 

 ous nerve, aponeurotic arch over Hunter's canal. 



Behind. Psoas, prcfunda vessels, pectineus, adductor longus, 

 femoral vein (at lower part of Scarpa's triangle, and in 

 Hunter's canal), tendon of adductor magnus. 



Inner side. Femoral vein (in Scarpa's space), adductor 

 longus. 



Outer side. Sartorius (in Scarpa's space), vastus internus, 

 femoral vein gets to outer side near ending. 



Branches : 



Superficial epigastric : arises $ inch below Poupart's liga- 

 ment, ascends through the saphenous opening to abdominal
