I have traced them in relation with several, and I haveno doubt that they exist in connexion with all the superficial arteries. They seem to bethe direct monitors to the artery of the presence or approach of danger. 459 e it lies Fig. 186/. PERONEAL NERVE. the posterior tibial vessels to enter the sole of the foot, wherin the interspace between the abductor pollicisand flexor brevis digitorqm; it then enters thesheath of the latter muscle, and divides oppo-site the bases of the metatarsal bones intothree digital branches; one to supply the ad-joining sides of the great and second toe; thesecond the adjoining sides of the second andthird toe; and the third the correspondingsides of the third and fourth toes. This dis-tribution is precisely similar to that of the di-gital branches of the median nerve. In its course the internal plantar nerve givesoil* cutaneous branches to the integument ofthe inner side and sole of the foot; muscularbranches to the muscles forming the inner andmiddle group of the sole; a digital branch tothe inner border of the great toe; and arti-cular branches to the articulations of the tarsaland metatarsal bones.
