Now in its Ninth Edition, Essentials of Human Anatomy & Physiology continues to set the standard for short-course A&P texts with an enhanced media package, an updated art program, and new "active learning" features that help allied health students better visualize and understand the structure and function of the human body. Elaine Marieb's clear and friendly writing style emphasizes the relevance of anatomy and physiology to students' lives and careers. It clarifies concepts, defines key terms, and offers just the right balance of anatomy, physiology, and clinical coverage to make the content complete without being overwhelming. While many authors merely condense a two-semester text to meet a one-semester need, Elaine Marieb wrote this book specifically for the one-semester course and continues to carefully select a range of material that proves just right for the shorter course. New information on hot topics like DNA fingerprinting, contraception, stem cell research, and obesity draws students into the material, while a flexible topic structure allows instructors to choose a chapter sequence to meet virtually any need. Thoroughly updated, the Ninth Edition offers instructors three options for online course management, including myA&Pa -- a comprehensive, customizable resource site for accessing tutorials, quizzes, review exercises, and other helpful instructor resources. WebCT and BlackBoard are also available. The book also includes Essentials ofInteractive Physiology(R), a new Media Manager, and a companion website.
