Dissection of the tibialis anterior muscle (TA). (a) Anterior view of the right TA (the tendon was cut at the ankle joint level). (b) The distal ends of the tibial attachment of the anterior and posterior fibers of the TA are shown. The distal part of the TA was turned over. The dotted curve shows the anterior border of the tibia. (c) and (d) Enlarged images of the white solid and dashed squares of (b), respectively. The black and white arrowheads indicate the most distal attachment points of the anterior and posterior fibers of the TA to the tibia. LM, lateral malleolus; MC, medial condyle; MM, medial malleolus; TA, tibialis anterior; TT, tibial tuberosity
