This section is from the book "Applied Anatomy: The Construction Of The Human Body", by Gwilym G. Davis. Also available from Amazon: Applied anatomy: The construction of the human body.
In this edition the general plan of the work has been retained. The text and illustrations have been carefully revised with many corrections and additions. The cuts have been made more accurate, ten have been entirely replaced and two new ones added. Our thanks are extended to our kindly critics who have aided us in making the book more accurate and useful.

It is not the object of this work to teach plain anatomical facts; its aim is to show the relation of structure to function, whether it is normal function or function disturbed or impaired by injury or disease. It is explanatory and utilitarian in character, and not encyclopedic. The bare facts of anatomy can be obtained from the systematic treatises, and they are here only briefly given in order to refresh the memory of the reader, who is supposed to be familiar to a certain extent with systematic anatomy. A person who has studied the subject only from a systematic standpoint cannot utilize and apply the knowledge so acquired unless he considers its relation to the various affections encountered in practice. He can study anatomy, but he will not see its application until it is pointed out to him. He may have studied the palmar fascia, but,.unless he is shown how its construction influences the course of pus originating beneath it, his anatomical knowledge is of little value. The inability to make any practical use of the facts or to see their application is the reason why anatomy is so frequently regarded as a dry, uninteresting study and too often designedly neglected.
In considering the subject, after a few general remarks on the part involved, the skeleton and muscles are briefly described, and thereby one is enabled to understand the surface anatomy, which immediately follows. Then comes a consideration of the various affections of the part, with such allusion to the nerves and vessels as is desirable to elucidate the subject. As the book is not intended to be a systematic treatise on anatomy, such anatomical facts as cannot be shown to be useful in practice are not mentioned. To give them here would make the volume too large, obscure its main object, and defeat its purpose.
As regards the anatomical nomenclature used, there is no system so generally accepted as to justify its exclusive adoption. In the desire, however, to aid in furthering the adoption of better anatomical terms, as much of the BNA terminology has been used, or included in parentheses, as a consideration of the subject from the standpoint of a general practitioner would allow.
Most of the illustrations are from original drawings of preparations made by the author and his assistants. Those derived from other sources are duly credited; if there has been any failure in this respect, it is unintentional.
The clinical material, except where otherwise stated, is from the author's own experience.
To the artist in charge, Mr. Erwin F. Faber, and to Mr. Herman Faber, who made a large number of the original sketches, my best thanks are due for their great skill, untiring energy, and most intelligent aid; their work speaks for itself.
I am under great obligations to many friends who have kindly rendered me their aid. Professor George A. Piersol has given me much valuable information and allowed me the unstinted use of his anatomical material; Dr. Astley P. C. Ashhurst made many of the dissections and aided in correcting and preparing the manuscript for the press; Dr. Frank D. Dickson did most of the proof-reading and prepared the index; Dr. T. Turner Thomas made many of the earlier preparations; and Dr. Henry Beates aided in the revision of the first portion of the manuscript. To these and others who have contributed to the formation of the book I desire to express my thanks.
To the hearty cooperation and unfailing generosity of my publishers is due the presentation of such an attractive volume. I asked them for nearly everything I could think of, and they gave me nearly everything I asked for.
In conclusion: this work is recognized as being far from complete, but it is intended to be suggestive rather than absolute. It is not designed so much to present facts as to furnish reasons, and it is hoped that it will appeal to the practising physician and surgeon as well as to the student.
