Anatomy. 692 THE VASCULAR SYSTEMS Boundaries.—The popliteal space is a lozenge-shaped space, widest at the back part of the knee-joint, and deepest above the articular end of the femur. It is bounded externaMy, above the joint, by the Biceps, and below the joint by the Plantaris and external head of the Gastroc- nemius. Internally, above the joint, by the Semimembranosus, Semitendinosus, Gracilis, and Sartorius; below the joint, by the inner head of the Gastrocnemius. Above, it is limited by the apposition of the inner and outer Hamstring muscles; below, by

Anatomy. 692 THE VASCULAR SYSTEMS Boundaries.—The popliteal space is a lozenge-shaped space, widest at the back part of the knee-joint, and deepest above the articular end of the femur. It is bounded externaMy, above the joint, by the Biceps, and below the joint by the Plantaris and external head of the Gastroc- nemius. Internally, above the joint, by the Semimembranosus, Semitendinosus, Gracilis, and Sartorius; below the joint, by the inner head of the Gastrocnemius. Above, it is limited by the apposition of the inner and outer Hamstring muscles; below, by the junction of the two heads of the Gas- trocnemius. The floor is formed by the lower part of the posterior surface of the shaft of the femur, the posterior ligament of the knee-joint, the upper end of the tibia, and the fascia covering the Popliteus muscle, and the space is covered in by the fascia lata. Contents.—It contains the popliteal vessels and their branches, together with the termi- nation of the external saphenous vein, the internal and external popliteal nerves and some of their branches, the lower extremity of the small sciatic nerve, the articular branch from the obturator nerve, a few small lymph nodes, and a considerable quantity of loose adipose tissue. Position of Contained Parts.—The in- ternal popliteal nerve descends in the middle line of the space lying superficial and cross- ing the artery from without inward. The external popliteal nerve descends on the outer side of the upper part of the space, lying close to the tendon of the Biceps muscle. More deeply at the bottom of the space are the popliteal vessels, the vein lying superficial to the artery, to which it is closely united by dense areolar tissue; it is a thick- walled vessel, and lies at first to the outer side of the artery, and then crosses it to gain the inner side below; sometimes the vein is double, the artery lying between the two venae comites, which are usua'ly connected ? by short t
