THE ENTAL PLANTAR NERVE, 



which lies ectad of the proximal end of the interosseus 

 muscles and within their substance, and crosses the foot 

 obliquely from the head , of the metatarsale of the fifth toe 

 toward the distal end of the metatarsale of the second. The 

 nerve trunk lies entad of the caudal border of the short flexor 

 and at the distal end of the second metatarsale (pollex want- 

 ing); it divides into a leash of four nerves, each of which 

 dichotomoses and innerves the interosseous muscles (M. int.); 

 slender filaments are given to the third layer of muscles. 

 The ental branch innerves the third and fourth lumbricales, 

 the three plantar interossei muscles, and the four muscles 

 which occupy the plantar arch of the metatarsalia — these 

 muscles have their origins at the proximal end of the meta- 

 tarsalia and insertion in the aponeurosis of the common ex- 

 tensor tendon and by a short tendon into the proximal end 

 of the proximal phalange. A portion of the muscle seems 

 to be equivalent to the dorsal interossei (anthropotomy ) , and 

 a portion is not satisfactorily homologized. The deep plantar 

 also innerves a muscle, which has its origin from the os 

 cuboides and crosses the plantar metatarsus obliquely and 

 inserts by a tendon upon the caudal surface of the proximal 

 phalange of the second toe, probably an adductor muscle. 



THE ECTAL PLANTAR NERVE 



bends around the tendon of the muscle, and, crossing its 

 ectal surface, lies entad of the tendon of the long flexor of 

 the second toe. At the distal end of the proximal segment 

 of the fifth toe it bifurcates, and can be traced to the pad of 

 the fourth and fifth toes. A slender filament is given to the 

 M. abductor minimus (Fig. M. ab. min.). 



N. PUDICUS (n. PUDENDUS). 



The pudic nerve (Pud.) has its ectal origin by two roots. 

 The sacral root is the largest of the terminal branches of the
