Independent Branches from Femoral Nerve 



seen are figured on the accompanying drawings, not ail, liowever, 

 being found on a single specimen. Although for the sake of reducing 

 the number of figures, it has been deemed advisable to represent the 

 right leg only, it is to be understood that the distribution to both 

 limbs is essentially the same. Moreover, while the actual number or 

 location of vascular filaments from any nerve or ultimately from any 



trunk, may vary to a con- 

 siderable extent in dif- 

 ferent individuals, yet 

 the general plan of dis- 

 tribution does not change. 

 The dissections which 

 form the basis of this 

 contribution do not deal with the vessels higher than 

 the inguinal ligament. The description will therefore 

 commence with the common femoral artery. I have 

 not found any filaments running directly to this vessel. 

 Its branches of bifurcation, the superficial and deep 

 femoral arteries and the medial and lateral circumflex 

 vessels, all derive their nerve supply, directly or 

 indirectly from the femoral nerve. As outlined in 

 figure 1, some of these twigs are independent; others 

 arise from muscular branches of the nerve, a case 

 in point being the filament represented passing to 

 the superficial femoral artery from 

 the nerve to the M. rectus femoris. 

 Figure 2 shows perhaps more clearly 

 the nerve distribution to this vessel, the 

 lower part of which frequently recei- 

 ves a twig from the saphenous nerve. 

 The popliteal artery derives its 

 supply in part directly from the 

 N. tibialis, but in addition receives 

 a branch in many cases from the azygos nerve. It has not been my 

 fortune to find a twig to this vessel from the N. obturatorius, but 

 that by no means negatives the existence in certain instances of such 

 a distribution. So far as my dissections go, the obturator nerve sup- 

 plied only the obturator vessels, and these through a continuous symp- 

 athetic plexus alone.
