A manual of anatomy . cruciate hga-ments and the menisci of the knee joint. The lateral condyleprojects well beyond the side of the shaft and presents a smalldorsolateral facet for articulation with the proximal extremity ofthe fibula. Ventrally the iliotibal band (tracMs iliotibialis) isattached, the tendon of the m. biceps femoris is inserted and themm. extensor digitorum longus and peroneus longus arise. Thedorsomedial margin of the medial condyle is grooved for the inser-tion of the m. semimembranosus. The tuberosity is slightly distalto the condyles; its proximal portion is covered by a bursa whilethe distal part receives the insertion of the ligamentum patellae. The shaft {corpus tibice) presents three surfaces and three proximal three-fourths is wedge-shaped (triangular in section) THE TIBIA 99 and its distal one-fourth is somewiiat flattened. Tiie medial surface,flat or convex, is extensive but mainly subcutaneous. On itsproximal portion the mm. gracilis and semitendinosus are Groove on internal malleolus Articular surface of malleolus Fig. 71.—The right tibia seen from infront. {Sobotta and McMurrich.) Inferior extremity Inferior arlicular surface Fig. 72.—The right tibia, seen frombehind. {Sobolta and McMurrich.) The proximal portion of the lateral surface is quite extensive andadords an extensive origin to the m. tibialis anterior; distally itturns and blends with the medial surface a sort of ventral is covered by the tendons of the mm. tibiaUs anterior, extensorhallucis proprius and the ext. digitorum communis. The dorsal lOO OSTEOLOGY surface is extensive and is usually convex proximally and flat convex portion is crossed by the oblique popliteal line proximalto which the m. popliteus is inserted; from the oblique line the arises. From the bulk of the remainder of the surface themm. tibialis posterior (laterally) and the flexor digitorum longus(medially) arise. The distal portion is merely co
