This new edition of an established textbook for medical students has been thoroughly updated and redesigned to include high yield learning tools and aids. The new edition also includes extensively revised coverage of developmental aspects and physiological variations due to age and gender. In addition, some important topics which usually receive scant attention in textbooks of physiology, such as ergonomics, the pineal gland and space physiology, have been given comprehensive treatment in new chapters. Most topics include self assessment material.
