second interosseous space. It also gives off from its convexity a 

 tarsal and a metatarsal branch. From the latter are given off two 

 interosseous branches for the two outer interosseous spaces.

Absence of the posterior tibial artery (right). 



In this dissection the popliteal artery is continued on in the leg 

 as a very large peroneal artery. A small branch, which may represent 

 the posterior tibial artery, arises at the level where the peroneal artery 

 is usually given off and runs downwards and inwards to terminate in 

 the deep aspect of the flexor longus digitorum muscle. The large 

 peroneal artery takes the usual course of an ordinary peroneal artery 

 to a point about half an inch above the ankle-joint. At this point it 

 gives off the anterior peroneal artery and then continues on to the sole 

 of the foot, dividing into internal -and external plantar arteries.

High radial artery (left). 



In this dissection the radial artery arises from the brachial artery 

 opposite the insertion of the coraco-brachialis muscle, and in its course 

 downwards lies on the biceps and brachialis anticus muscles. It 

 crosses the median nerve from without inwards. On passing below 

 the bicipital fascia it is joined by an anastomosis from the ulnar 

 artery.

High division of the great sciatic nerve. 



At the level of the lower border of the pyriformis muscle the 

 great sciatic nerve has already divided into two ; the upper division
