FEMORAL VEIN 167 



and at the ankle lies between it and the outermost tendon of 

 extensor longus digitorum. The artery is accompanied by venaa 

 comites. 



Branches. 1. Muscular to adjacent parts. 



2. Cutaneous to skin of front of leg. 



3. Internal malleolar anastomoses with posterior 



tibial. 



4. External malleolar anastomoses with peroneal. 

 Dorsalis Pedis artery is the direct continuation of the anterior 



tibial artery from the front of the ankle-joint to the posterior 

 extremity of the first interosseous space, where it anastomoses 

 with the external plantar artery to form the plantar arch. It 

 lies on, successively, anterior ligament of the ankle-joint, head 

 of the astragalus, navicular bone, inter cuneiform ligaments. 



It is covered by skin and fascia and the lower part of the 

 anterior annular ligament. 



The internal terminal branch of the anterior tibial nerve lies 

 on the outer side of the artery, between it and the extensor 

 brevis digitorum. 



The tendon of extensor proprius hallucis lies on the inner side, 



Branches. 1. Cutaneous to skin of dorsum of foot. 



2. Dorsalis hallucis runs on first interosseus muscle and sup- 

 pies first and second toes. 



3. Metatarsal arises just before termination of artery, and, 

 running outwards, gives off branches to supply the digital clefts, 



Veins of the Lower Limb. 



The veins of the lower limb are arranged in a similar manner 

 to those of the upper limb, in two groups superficial and deep. 



The Deep veins consist of venge comites accompanying all the 

 arteries in the leg, which unite to form the Popliteal vein at the 

 lower border of popliteus. The popliteal vein passes upwards 

 through the popliteal space, at first on the inner side of the 

 artery and above on the outer side ; it then passes through the 

 opening in adductor magnus and becomes the femoral vein. 



The Femoral vein is the direct continuation of the popliteal 

 vein. It ascends through Hunter's canal and Scarpa's triangle,
