Dorsal artery. — The line of this is from the centre of the ankle-joint to the 

 upper part of the first interosseous space. On its inner side is the tendon of the 

 extensor proprius hallucis; on its outer, the innermost tendon of the extensor 

 longus digitorum. It is crossed by the innermost tendon of the extensor brevis. 

 The origin of this muscle should be marked on the outer and fore part of the 

 calcaneum.

Cutaneous nerves (figs. 764, 770). — The sites of these, numerous on the 

 dorsum of the foot, are as follows: — The musculo-cutaneous nerve, having 

 l)erforated the fascia in the lower third of the leg, divides into two chief branches, 

 inner and outer, which supply all the toes save the outer part of the little, and 

 the adjacent sides of the first and second. The anterior tibial l)ecomes cutaneous 

 in the first space, and is distributed to the contiguous sides of the above-mentioned 

 toes. Tlie external saphenous nerve runs with its vein below the malleolus, 

 and supplies all the outer l)ordi'r of the foot and the outer side of the little toe. 

 The internal saphenous nerve, coursing with its vein in front of the internal
