division of the fossa ; as a rule, the pulsations of the popliteal artery can be felt. 

 Deep to the semitendinosus is the fleshy semimembranosus, which bulges into the 

 space and overlaps the proximal part of the popliteal artery. Between the semi- 

 membranosus and the medial head of the gastrocnemius is the most important 

 bursa in the popliteal region ; it not infrequently becomes distended with fluid, 

 and then presents usually a more or less sausage-shaped outline ; according to 

 Holden, the bursa communicates with the cavity of the knee-joint in one subject 

 out of five. 



To map out the line of the popliteal vessels and the tibial nerve, draw a line

from a point a little medial to the proximal angle of the space to a point midway 

 between the condyles of the femur, and thence dis tally along the middle of the 

 space to the level of the distal part of the tuberosity of the tibia. The tibial nerve 

 lies immediately under cover of the deep fascia ; the artery is separated from the 

 popliteal surface of the femur by a quantity of fat. The popliteal lymph glands 

 lie deep to the popliteal fascia, one upon the tibial nerve, the others deeply in the 

 space (Leaf). 



THE FRONT OF THE THIGH. 



Between the front of the thigh and the abdomen is the fold of the groin, at the 

 bottom of which the inguinal ligament can be felt as a tense band, stretching from 

 the anterior superior spine of the ilium to the pubic tubercle. The anterior 

 superior spine looks directly forwards; comparative measurements of the inferior 

 extremities are made by stretching a tape from it to the tip of one or other of the 

 malleoli, care being taken that the pelvis is horizontal, and the limbs in corre- 

 sponding positions. The pubic tubercle is felt under the proximal and lateral part 

 of the mons Veneris and at a corresponding point in the male; between the 

 tubercle and the symphysis is the crest of the pubis, the two crests together
