Physiology Unlocked: A Chapter-Wise MCQ Bank Based on Recommended Core Textbooks With Explanations and Page-Referenced Clarity

By Dr. Uthayasooriya Amarasena

Preface
In the evolving landscape of medical education, the need for clarity, compassion, and clinical relevance has never been greater. Physiology Unlocked was born from a simple yet profound question: How can we help students not just memorize physiology, but truly understand and apply it?
This book is a response to that question-a modular, chapter-wise MCQ bank meticulously aligned with Guyton & Hall, Ganong, and Sembulingam, the cornerstone texts of human physiology. Each question is crafted with care, not only to test knowledge but to deepen it. Explanations are concise yet illuminating, mnemonics are woven in to aid retention, and every item is ethically referenced to its source.
As an author and clinician, I have witnessed the transformative power of student-centered learning. This resource is designed to empower learners-whether preparing for exams, revising core concepts, or integrating physiology into clinical reasoning. It is also a tribute to the resilience and curiosity of Sri Lankan medical students, whose pursuit of excellence continues to inspire.
I extend my gratitude to the giants of physiology whose texts guide us, and to every student and teacher who believes that learning can be both rigorous and humane. May this book serve not only as a tool for success, but as a companion in your journey toward becoming a thoughtful, compassionate healer.
