Dorsal Surface. In the superficial fascia of the 

 dorsum of the foot the following nerves are found, viz. : 

 The terminations of the internal saphenous, along the in- 

 ner border; the branches of the musclo-cutaneous over 

 the greater part of the dorsum, and the short saphenous 

 nerve along the outer side of the little toe. Over the toes, 

 the integument is supplied as follows : The adjoining sides 

 of the great and second toes are supplied by the anterior 

 tibial ; the outer side of the little toe by the short saphe- 

 nous and the remaining toes by the musculo-cutaneous. 

 Anterior annular ligament. The vertical part has already 

 been described on page 366. The horizontal portion is 

 composed of bands of fascia arranged somewhat like the 

 letter Y. The base or body of the Y is attached to the os 

 calcis in front of the depression for the interosseous liga- 

 ment and splits to enclose the extensor longus digitorum 

 and the peroneus tertius along with their common syno- 

 vial membrane. At the inner border of these tendons the 

 upper branch, or limb, passes up towards the inner malleo- 

 lus, enclosing by a splitting of its fibres, the tibialis anticus 

 and its synovial sheath, but passing over the extensor 

 proprius hallucis, anterior tibial nerve and the bloodves- 

 sels. The other or lower limb passes downwards to the
