INTRODUCTION A comprehensive knowledge regarding the innervation and disposition of various nerves supplying the appendages in ox, sheep, goat, pig and horse is essential from a com parative anatomical standpoint and for the sake of "applied" or "practical" anatomy, in order to satisfactorily accomplish various nerve "blocks and to perform satisfactory surgery. A specific knowledge about the nerve supply to a particular region may, in turn, aid in the diagnosis of the area of involvement when certain nerves are affected by fracture, trauma, tumor, etc. Diseases of the feet of livestock often impair their utility and cause economic loss to the farmer, and indirectly to the country. Therefore, this investigation has both academic and practical application. Moreover, the pig and small ruminants (e.g. sheep and goat) are frequently used as experimental animals in various research institutions around the country and abroad. How ever, very little information to date is available in the literature, especially in English, on the nerve supply .to the appendages of the pig and small and large ruminants. There are few references to the innervation of the digital regions in the goat, although it has been assumed that possibly there is no significant difference in the pattern of distribution of nerves in these regions than those of 2 the ox and sheep. Thus, in order to obtain detailed in formation in this area and for a better understanding of the domestic species differences, if any, this investigation has been undertaken. Within the framework of the present investigation, the innervation of the forearm or "antebrachium" and foot or "manus" of the forelimb and leg or "crus" and foot or "pes" of the hind limb has been studied. At times, information regarding the origin of some nerves supplying these regions has been included in the observations to present a more comprehensive picture. For all practical purposes, the Nomina Anatomlca Veterinaria (Pars prima) approved by the International Commission on Veterinary Anatomical Nomenclature (I.C.V.A.N.) in 1963, was used for the nomenclature of the muscles and, whenever possible, the Nomina Anatomlca (1955) was used for the nomenclature of the nerves. 3 II. REVIEW OF LITERATURE A. Innervation of the Forearm and Foot of Domestic Animals 1. Ox a. ^ ulnaris From the ulnar nerve arises the N. cutaneus antebrachii caudalis s. proprius, soon after its separation from the N. medianus. Reimers (1925b) and Schreiber (1956a) state that the caudal cutaneous nerve of the forearm immediately divides into a cranial and a caudal twig. The Ramus cranialis lies on the medial side of the forearm and is covered by the M. pectoralis transversus, appears within the proximal third under the fascia, runs distally and somewhat on the volar surface, and ends at the level of the carpus.
