 branch of the ])osterior tibial artery (fig. 379).

 digitorum, and through the interval between the middle and outer portions of the 

 plantar fascia, to the skin. 



(4) The anastomotic turn over the outer border of the foot, and anastomose 

 with the tarsal and metatarsal l^ranches of the dorsalis pedis (fig. 381). 



(5) The articular come off from the concavity of the arch, and, running back- 

 wards and upwards, are distributed to the articulations of the tarsus. They are

homologous to the recurrent branches of the deep palmar arch in the hand, and, 

 like the latter, are usually three in number. 



(6) The posterior perforating, also three in number, ascend through the 

 proximal end of the second, third, and fourth spaces, between the two heads of 

 the correspondingly named dorsal interosseous muscles, and communicate with the 

 proximal ends of the first, second, and third interosseous arteries (fig. 381). 



(7) The digital or plantar digital arteries are usually four in numl)er, and 

 are distributed to the inner and outer sides of the third, fourth, and fifth toes, 

 and to the outer side of the second toe. They are named first, second, third, and 

 fourth as they come off from the arch from without inwards, and not according to
