It may also come to the aid of learners of allied medical sciences. Significant features of this book: Topics presented in a lucid language as-introduction, functional anatomy, elaboration of concepts and clinical/applied/pathophysiology. Numerous heads and subheads along with highlighted important terms to assist memorisation of topics and effective presentation during examination. Novel methods of explanation for easy understanding of complex principles and topics such as—Ionic Equilibrium and Resting Membrane Potential, CNS, Yoga etc. Highlighted coloured boxes for clinical/applied/pathophysiology and current advances. 670 coloured figures (illustrations, images, photographs, flow charts) and 137 tables (almost one figure/table in every page!) to make the text clearly understandable and more meaningful. Many unique illustrations and tables that have not appeared ‘….in any textbook so far’. ‘At a Glance’ at the beginning and ‘Recap’ at the end of each chapter. Coloured boxes providing nuggets of information, tit-bits, snippets, notes, thought-provoking riddles and facts connected to human physiology. Question bank with short notes/essay-type questions and MCQs (with answers) to assist the student in self assessment.
