Most textbooks and atlases of human anatomy describe only a few cases of variations in the ’normal’ human population, or of anomalies of the muscles. These variations and anomalies are also often excluded from the curricula in colleges of medicine and dentistry in the U.S.A. and in many other countries. However, it is known that each person within the ’normal’ population has at least a few muscle variations, and there are millions of individuals born globally every year with muscle anomalies. It is highly likely that during their careers, almost all medical professionals working with any aspect related to muscles - including muscle physiology, gross anatomy, physiotherapy, surgery - will be faced with at least a few cases of muscle variations and/or anomalies. There are therefore crucial gaps of knowledge between what teachers of medical and dentistry schools teach, what students learn, what textbooks and atlases show, and the reality that medical professionals will face in practice during their careers. This is the first textbook and anatomical atlas to address this topic in a holistic way by: 1) providing a comparative evolutionary context for the existence of variations and defects in humans, 2) summarizing the major types of variations and anomalies found in the skeletal muscles of humans, and 3) including schematic figures for an easy visualization of these variations and anomalies. The book is therefore of interest to students, instructors, professors, researchers from fields such as biological anthropology, comparative anatomy, functional morphology, zoology, and evolutionary and developmental biology, and health practitioners.Key Features1 –2 –3 –4 –5 –Related Titles
