NERVES 



1 Anterior crural. 



2 Branch of anterior crural to pectineus. 

 8 Internal cutaneous of anterior crural. 

 4 Middle cutaneous of anterior crural. 



6 Nerve to vastus internus. 



Internal or long saphenous. 



7 Nerve to rectus. 



8 Nerve to vastus externus. 



9 Twig from the last which accompanies 



h' and reaches the knee-joint. 



10 Nerve to crureus, also sending a twig 



to the vastus internus. 



11 Superficial division of obturator. 



12 Branch of superficial division which 



supplies the adductor longus; carries 

 with it (1C) the Ewig to the obturator 

 plexus. 



13 Branch of obturator to adductor brevis. 



14 Branch of obturator to gracilis. 



15 Deep division of obturator. 



16 Branch of superficial division of 



obturator which joins obturator or 

 subsartorial plexus, and is distri- 

 buted to skin, also giving a vaso- 

 motor twig to femoral artery. 



17 Branch of long saphenous which joina 



the obturator plexus. 



18 Ilio-inguinal nerve.
