 evident a proximal subinguinal group along the line of the 

 inguinal ligament, immediately distal to the attachment of

FIG. 106. Superficial Dissection of the Proximal Part of the Front of the 

 Thigh. The fossa ovalis (O.T. saphenous opening), the superficial lymph 

 glands and vessels of the groin are displayed. The lymph vessels may 

 be recognised by their beaded appearance.

 extends for a short distance distally along the line of the 

 great saphenous vein. Both groups are separable into medial 

 and lateral parts.
