upper tendon stands out as a prominent ridge running obliquely downward and lateralward from the neighborhood of the public tubercle, and forming the medial border of the femoral triangle. The lower tendon of Adductor magnus can be distinctly felt as a short ridge extending downward between the Sartorius and Vastus medialis to the adductor tubercle. The adductores fill in the triangular space at the upper part of the thigh, between the femur and the pelvis, and to them is due the contour of the medial border of the thigh, the Gracilis contributing largely to the smoothness of the outline.
The Glutæus maximus(Fig. 1239) forms the full rounded outline of the buttock; it is more prominent behind, compressed in front, and ends at its tendinous insertion in a depression immediately behind the greater trochanter; its lower border crosses the gluteal fold obliquely downward and lateralward. The upper is part of Glutæus medius visible, but its lower part with Glutæus minimus and the external rotators are completely hidden. From beneath the lower margin of Glutæus maximus the hamstrings appear; at first they are narrow and not well-defined, but as they descend they become more prominent and eventually divide into two well-marked ridges formed by their tendons; these constitute the upper boundaries of the popliteal fossa. The tendon of Biceps femoris is a thick cord running to the head of
