Fig. 204 Introduction K,rncledge of tlze structure and function of the body of healtlzy a11i111als is a basic prerequisite to 111aste1y of dinirnl and certain /He-clinical dimplines. The first stejJ is study of tlze body according to its scwral org((n systems, i. e., a dh ision of tlze body into its different parts for systematic and detailed 1 stur(J·. Hm,•e,·e1; systematic anatomy is only one asjJect of tlze study of Jmxtical anatomy for 1 1eteri11a- 1y jJmctice. Familiarity witlz both mutual interrelations/zips and positions of specific organs and structures is also essential. Tlzis synthesis of knowledge is the goal of students and teaclzers, and requires great efforts from both. TV/zile �rstematic anatomy ini'Oh es a great deal of memorization, tlze ability to 111e11tally 1 1isualize 1 a11ato111ic structures in dejJt/z is required in tlze study of topographic anatomy. DevelojJ111e11t of tlzis '�jXltia! jJercejJtion" in tlze student is tlze resjHmsibility of tlze anatomy teache1; to lze!p sujJp/y tlze best possible jJrejx1ratio11 for clinical studies. In tlze teaching of a11ato1II)\ tlzerefore, great emplzasis is jJ!aced 011 metlzodical and logical presentation of material. Here the Atlas. is intended to lze!p botlz tlze teaclzer and tlze student. Tlze jJractitioner occasionally encounters situatiom in which a review of topographic anato111y is needer/, but ,d1en a return to "tlzeo1y" would be naturally undesirable and time-co11sumi11g: /11 these sit11atiom, ,c,J1e11 a s11111mmy of jJertinent i11for111atio11 is wanted, the author hopes the Atlas 1oill be ,·aluable to the practitio11e1; and ab01 1e all to the surgeon and the internist, esjJecially since at present nu similar atlas is amilab!e. In tlze JnejX1ration of tlze Atlas, tlze author has taken into consideration the demands imposed by Jm1ctice of ,·eterinmy medicine. /11 selecting the material, howe1 1e1; he has considered it his duty to include a11i111als frequently neglected in other anatomy texts, i. e., sheejJ, goat, and swine. Tlze anato111ic differences between small and large m111inants are so great that tlzey cannot be summarized under tlze lzeading of small ruminants, as is the case in more co111prelze11sh e texts. 1 T/1(' Atlas is not intended to be a co111jJlete source for tlze study of 1 1eteri11my anatomy. Professional peojJle 111<()' find it too general in scojJe, students too detailed. Students in partiwlar should be aware tlzat tlze Atlas cannot be considered a rnbstitute for textbooks or handbooks (or other atlases), nor a substitute for the jJractica! study of dissected sjJecimens. Neither tlze best atlas nor the best textbook rnn rejJlace jJractirn! experience. The exact color and consistency as well as otlzer properties of the org((I/S and tissues cannot be exjJressed by tlze written word, nor reproduced pe,fectly in illustrations. In tlzis sense, m1 atlas has a limited use. Therefore less attention lzas been gil 1e11 to tlzose questions tlzat can be better studied in textbooks of systematic anatomy. Finally, it was impossible, for teclznical reasons, to jJresent all details in the drawings. This was especially true for some features whiclz could 9 hm·e been rejJresented only with loss of the gelleral view. In these cases, h6weve1� the reader call obtaill a cu1njJrehellsiz•e jJicture either by utilizing a series of drawillgs or by studying textbooks of :,ystenwtic anatomy. The needs o/ jJractitiollers ill applied anatomy 1•ary fro111 one discijJ!ine to the next: The surgeon's req11ire111ents ,t•i!l differ fro111 those of the internist or of the hygienist (e. g:, a 111eat insjxctor). It is understood that one j)l{blication cannot satisfy the demands of all. Howel'e1� the author hopes that the Atlas, in spite of these li111itations, will be a positfre contribution to the literature, and an aid to both the student and the jJrofessional Last, it must be e111phasized that an atlas should not be dogmatic. While the Atlas is quite inc!ushie in the J11aterial it />resents, the broad scale of indil'idual 1'(Jriations o/age and sjJecies dif/erences cannot be presented in a single work. All the figures, ,cith a few excejJtions, are origillal, drawn according to preparations made by the author using the rnsto/J/m)' anatomic 111ethods. When drawings are taken from other authors, ajJ­ pmjJriate credit is gh•en ill the Table of Contents. Fresh as well as fixed materials were used for the preparations, alld serial sections were prepared/ram frozen sjJecimens. Most figures, including later corrections, were jJrejxtred by the author himself; Mrs. L. Suttm•a, artist o/ the Department, heijxd u.:ith drawing of so111e preparations of bones, exteriors, and brains. T'ol11111e 1 o/ the Atlas 1c•as published in 1960, Volume 11 in /962 and Volume 111 in 1968, alld it has been translated into se,:eral languages. Despite deficiencies of which the author is aware, the Atlas has ajJj)({rent(v jJro,•ed a 1•aluable reference, judging jrolll the response to the first jJrinting and the number rl cujJies in use. Hozt1e1•e1; for this new edition, the J11aterial has been ujJdated in accordance 1cith the anatoJ11ic noJ11e11c!ature, NA. V., adopted in 1973. Where necessary, figures haz•e also been 1Nisecl, and the author has added se1•eral new topograjJhic and anatomic z·iews. Pr o f. Pe t e r Po p e s k o , D .M . V ., D r .Sc .
