Study Notes

Medical Physiology Book Editions

  • Multiple editions of the book are produced; each one improves from the last.
  • Readers' comments and suggestions help to better shape the book.
  • The current edition includes more flowcharts, tables, and diagrams for better understanding.
  • Chapters are updated based on input from teachers and colleagues.
  • The authors are continuously seeking ways to improve the book, relying on feedback.

Preface to the First Edition

  • The book aims to provide a simple introduction to medical physiology.
  • The book is designed for medical students, dental students, and allied health students.
  • It covers the basic principles of physiology for each body system.
  • Applied aspects of physiology are also included.
  • Diagrams are schematic for better understanding.
  • Each section has probable questions to help students prepare for exams.
  • Thorough reading of each section is advised.
  • Feedback and suggestions are highly valued.

Acknowledgements

  • Appreciation is expressed for the support of influential figures.
  • Acknowledgment to Late Mr NPV Ramasamy Udayar, Founder Chancellor, Sri Ramachandra Medical College and Research Institute.
  • Gratitude towards Sri VR Venkatachalam, Chancellor, for releasing the book.
  • Appreciation expressed for Dr TK Partha Sarathy, Vice-Chancellor, for attending the event.
  • Thanks to Mrs Radha Venkatachalam, Registrar and Administrative Director, for encouragement to faculty publications.
  • Appreciation is expressed for Dr Sylvia Walter, Professor Emeritus, for inspiration and helpful modifications to the script.
  • Special thanks are extended to Dr V Srinivasan, former Professor and Head of the Physiology Department, for his enthusiasm, encouragement, and suggestions.
  • Acknowledgment to fellow teachers and professors for comments and suggestions.
  • Deep gratitude for students at Sri Ramachandra Medical College and MR Medical College for their input in creating the book.

Additional Information

  • The book covers different body systems, including the coronary, cerebral, and splanchnic circulations, as well as capillary, skeletal muscle, cutaneous circulation, and fetal circulation.
  • Sections on hemorrhage, circulatory shock, exercise adjustment, the respiratory system, pulmonary circulation, respiration mechanics, and pulmonary function tests are included.

General Physiology

  • Cell Structure: The cell membrane is a three-layered structure with lipid and protein components.
  • Different models (including Danielli–Davson) explain the membrane composition.
  • The cell consists of a cell body, nucleus, and cytoplasm.
  • Nucleus: A double-layered nuclear membrane separates the nucleoplasm from the cytoplasm. It contains chromatin, packed into nucleosomes that condense to form chromosomes during cell division. The nucleus controls cell division and is found in most cells in the body.
  • Cytoplasm: Contains components and organelles
  • Microfilaments: Actin and myosin are protein components of microfilaments.
