product of extensive research and professional synthesis; any unauthorized use,
particularly for the training of generative artificial intelligence models or large language
models, is strictly prohibited unless specifically authorized in writing by the publisher.

This book is intended for use by medical professionals, students of the health sciences,
and researchers. While every effort has been made to ensure that the anatomical
descriptions and clinical correlations provided are accurate and reflect the current state
of medical knowledge at the time of publication, the nature of medical science is one of
constant evolution. The information contained herein should not be used as a substitute
for professional medical advice, diagnosis, or treatment. Neither the author nor the
publisher assumes any responsibility for errors or omissions in the text, nor for any
injury or damage to persons or property resulting from the application or use of any
information, methods, or instructions contained in this volume.

Readers are cautioned that anatomical variation is a fundamental characteristic of the
human species. While this atlas illustrates the "standard" or "most frequent" anatomical
configurations, clinical reality often presents significant deviations. Surgeons and
practitioners must rely on their clinical judgment and site-specific diagnostic imaging
when treating patients. The mention of specific pharmaceutical products or surgical
instruments does not imply endorsement by the author. Furthermore, all cadaveric
imagery and anatomical specimens depicted in this work have been sourced from
institutions adhering to the highest ethical standards of body donation and anatomical
study. We acknowledge with profound gratitude those individuals who, through the gift
of their bodies, have contributed to the advancement of medical education for future
generations.
