Discover a unique approach of combining descriptive anatomy with clinical information on the abdomen and pelvis of domestic mammals

King’s Applied Anatomy of the Abdomen and Pelvis of the Domestic Mammals delivers a thorough and accessible exploration of the abdominal and pelvic anatomy of domestic animals in a clinically relevant style.

Designed as a refresher for veterinary students beginning to engage in clinical procedures, the book uses clinical illustration to teach the essential principles of how the abdomen and pelvis of domestic mammals are constructed. It covers core topics such as: - Thorough introductions to the body wall, the mesenteries and ligaments of the abdomen and pelvis, and the gastrointestinal tract - Explorations of the liver and the pancreas, the spleen and abdominal lymphatics, and the biology of digestion - Practical discussions of the autonomic and somatic nerves of the abdomen and pelvis and the male and female reproductive organs - Treatments of laparotomy and diagnostic imaging of the abdomen and pelvis

Perfect for veterinary students studying anatomy, King’s Applied Anatomy of the Abdomen and Pelvis of the Domestic Mammals will also be useful to practicing veterinary practitioners, students of veterinary nursing, and people studying animal science and related disciplines.
