NERVES OF THE INFERIOR EXTREMITY.

outer side of the little toe, and the other divides so as to 

 supply the opposing sides of the little and the fourth toe. 

 The external plantar supplies the various muscles in its 

 course, as well as the integuments on the outer margin 

 and sole of the foot. 



PERONEAL NERVE, (Fig 263.) 



This nerve is the external popliteal, or second division 

 of the great sciatic. It descends, along with the tendon of 

 the biceps, to the head of the fibula, FIG. 264. 



where it divides into the anterior tibial 

 and external peroneal branches. Be- 

 fore this division it sends off two long 

 branches, called the external and in- 

 ternal peroneo-cutaneous nerve, the 

 former being distributed to the in- 

 teguments along the fibula, the latter 

 descending on the gastrocnemius, and 

 about the middle of the leg uniting 

 with the external saphenus or com- 

 municans tibiae. 



The anterior tibial nerve (Fig. 259) 

 descends in front of the interosseous 

 ligament, along with the anterior 

 tibial vessels, to the ankle, where it 

 passes under the annular ligament, 

 and is distributed to the muscles 

 and integuments on the dorsum of the foot and the two 

 first toes ; it supplies the various muscles in its course. 



The external peroneal or musculo-cutaneous nerve (Fig. 

 259) descends the leg between the peroneus longus and 

 extensor longus digitorum, and about the middle of the 



FIG. 264 represents the Plantar Nerves. 1 Posterior tibial. 2 Abductor 

 pollicis. 3 Flexor brevis digitorum. 4 4 Section of tendons of this latter 

 muscle. 5 5 Abductor minimi digiti. 6 Musculus accessorius. 7 External
