This book presents a unique combination of important viva questions and answers of all the three subjects (Anatomy, Physiology and Biochemistry) taught in the first professional examinations. Its unique presentation in the form of three-column format, adequately equipped with appropriate illustrations would make it an interesting reading for the students. The students must, however, remember that the book is in no way a replacement for standard textbooks in anatomy, physiology and biochemistry. Nothing can be a replacement for a standard textbook in a particular subject, which would help clarify the various concepts and fundamentals. The students must remember that “the mouth speaks only those what the mind knows”, so nothing can be replacement for a sound and effective examination preparation. Strong foundation in these three basic subjects goes a long way in the development of an undergraduate student into a full fledged doctor. Thus, the students must try to grasp all the important concepts before they start reading this book. This book is meant only for the aid and assistance to the first professional examination and for removing all the fears from the students’ mind.
