SURFACE MARKINGS 223 



abductor hallucis forms a fleshy pad along the inner border of 

 the foot. 



The dorsalis pedis artery is mapped out by a line drawn from a 

 point midway between the two malleoli (the termination of the 

 anterior tibial artery) to the hinder end of the first interosseaus 

 space. The internal saphenous vein and nerve lie between the 

 internal malleolus and the tendon of tibialis anticus ; the external 

 saphenous vein and nerve follow the tendon of peroneus brevis. 



The internal plantar vessels and nerves lie along a line drawn 

 from the under surface of the inner tuberosity of the os calcis to 

 the interval between the first and second toes. The external 

 plantar vessels and nerves are on a line drawn from the middle of 

 the under surface of the heel to the fourth toe; the course of 

 the plantar arch is mapped out by a line drawn across the sole 

 from the inner side of the base of the fifth metatarsal to the 

 hinder end of the first interosseous space.
