Medical Physiology: Objectives and Multiple Choice Questions, Second Edition defines explicitly what students should be able to accomplish at the end of a one-year course in human physiology and related biochemistry. The book contains sets of objectives, which outlines the factual knowledge required in a way that should encourage self-study, critical appraisal, and the use of many sources of information. The text presents outlines of topics on basic chemical, physical, biochemical, and physiological concepts. It also provides learning objectives for cell biochemistry, body fluids, connective and support tissue, excitable tissue, nutrition, thermoregulation, and the nervous system. A set of multiple choice questions is found at the end of each section to test the student's knowledge. Medical students, physiotherapy students, occupational therapy students, nursing students and students in related medical sciences will find the book very useful.
