Human Anatomy, 3rd Edition
Human anatomy is a fascinating field that has many layers of complexity. The subject is difficult to teach, and students can often be overwhelmed by its massive amount of material. Our goal in writing Human Anatomy was to create a textbook that guides students on a clearly written and expertly illustrated beginner’s path through the human body. Across three editions, we have striven to make this book enjoyable to read, easy to understand, pedagogically efficient, and visually engaging. The following pages highlight the enhancements we’ve made to the third editionas well as the hallmark features that define this book.
What’s New in This Edition?
New research findings, shifting terminology, technological advancements, and the evolving needs of students and instructors in the classroom require textbook authors to continually monitor and revise their content. Throughout the third edition, changes have been made to incorporate the latest information, bring terminology up to date, and improve wording to make discussions easier for students to read and understand. In addition, we have implemented some simple pedagogical changes to facilitate easier referencing and coordination with supplemental resources.
■ Each chapter section begins with a set of numbered learning objectives.
■ All first- and second-level section headings are numbered to allow easier reference to specific areas of the book.
The following list is by no means exhaustive, but it highlights some of the changes made in each chapter.
1. A FIRST LOOK AT ANATOMY Changed figure 1.5 to an anterolateral view so the coronal plane is more obvious. Added a brief discussion on orienting sections right to left in the Clinical View on medical imaging.
2. THE CELL: BASIC UNIT OF STRUCTURE AND FUNCTION Clarified that simple diffusion can occur without a membrane. Updated figure 2.8 to show the endoplasmic reticulum is continuous with the nuclear membrane. Modified figure 2.9 (Golgi apparatus) to adjust the relative sizes of the receiving and shipping regions.
3. EMBRYOLOGY Updated the discussion regarding the acrosomal reaction to include most recent research information. Added a short description to the cleavage discussion regarding how the blastocyst leaves the zona pellucida.
4. TISSUE LEVEL OF ORGANIZATION Updated the discussion of the basement membrane and figure 4.1 to include three layers. New examples of apocrine secretion to mammary glands and ceruminous glands. Expanded the descriptions of hyaline and fibrocartilage. Updated the description of the synovial membrane. New micrographs and drawings of ciliated columnar epithelium, cardiac muscle, and smooth muscle.
5. INTEGUMENTARY SYSTEM New Clinical View describing several current surgical and laser treatments for aging skin. Added information on sensible and insensible perspiration; the transfer of melanosomes from melanocytes to keratinocytes via phagocytosis or exocytosis; the number of ceruminous glands in the external auditory meatus and the presence of lysozyme in cerumen; and hair stiffness. Updated the information about friction ridges and grip. Revised figure 5.7 (lines of cleavage) to clarify potential for gaping wounds with perpendicular versus parallel incisions. New micrograph of longitudinal section of hair (figure 5.9b) and expanded coverage of the hair growth cycle.
6. THE SKELETAL SYSTEM: CARTILAGE AND BONE Added the medullary cavity as a location of red bone marrow in children. Made the distinction between bone as organ and bone connective tissue. Reorganized bone fracture coverage to reflect the different classifications used in describing fractures. Reworked the fracture repair discussion.
7. THE SKELETAL SYSTEM: AXIAL SKELETON Rotated lateral views of skulls so photos and drawings are oriented in the Frankfort plane. Added new photos with improved contrast and detail for figures 7.4, 7.5b, 7.6, 7.7, 7.8, 7.13a, 7.13b, and table 7.4. Improved contrast of photos in figures 7.5a, 7.10, 7.12a, and 7.12b. Added information about how angles of vertebral facets contribute to different movements; size of vertebral foramen; and palpation of vertebra prominens.
8. THE SKELETAL SYSTEM: APPENDICULAR SKELETON Added new photos with improved contrast and detail for figures 8.9a, 8.9b, 8.11a, 8.13a, and 8.13d. Improved contrast of photos in figures 8.4a, 8.4d, 8.5a, and 8.5f.
9. THE SKELETAL SYSTEM: ARTICULATIONS Added Clinical View on joint replacement. Updated information on osteoarthritis.
10. THE MUSCULAR SYSTEM: MUSCLE TISSUE AND ORGANIZATION New analogy for sliding filament. Clarified role of ATP in powering muscle contraction and added concept of recruitment. Updated role of intermediate fibers.
11. THE MUSCULAR SYSTEM: AXIAL MUSCLES New Clinical View on congenital muscular torticollis. Clarified discussion of pelvic floor muscles.
12. THE MUSCULAR SYSTEM: APPENDICULAR MUSCLES Added Study Tip for rotator cuff muscles. Reorganized discussion of pectoral girdle muscles superficial to deep.
13. SURFACE ANATOMY Updated CPR Clinical View per current American Heart Association information. Added landmarks for posterior, superior iliac spine. Clarified landmark and clinical use of dorsalis pedis artery.
