known as Scarpa's triangle. In this situation the beating of 

 the artery may be felt, and the circulation through the vessel 

 may be most easily controlled by pressure. 

 The popliteal artery, 



continuous with the fem- 



oral, is placed at the back 



of the knee ; just below 



the knee joint it divides 



into the anterior and 



posterior tibial arteries. 

 The posterior tibial ar- 



tery lies along the back 



of the leg, and extends 



from the bifurcation of 



the popliteal to the 



ankle, where it divides 



into the internal and 



external plantar arteries. 

 About an inch below 



the bifurcation of the 



popliteal, the posterior 



tibial gives off a large 



branch, the peroneal ar- 



tery. 



The anterior tibial ar- 



tery, the smaller of the 



two divisions of the 



popliteal trunk, extends 



along the front of the 



leg to the bend of the 



ankle, whence it is pro- 



longed into the foot 



under the name of the 



dorsal artery. This jgj?w ff f ,
