Foundations of General Physiology and Nerve-Muscle Biology

Understanding how the human body functions at a cellular level is the key to mastering complex medical and biological sciences. This comprehensive text-based course breaks down the fundamental mechanisms governing cellular transport, communication, and excitability. By working through this structured written guide, you will transition from memorizing isolated facts to deeply understanding the physical and chemical principles behind physiological processes. You will gain the conceptual framework required to analyze systemic physiology and clinical scenarios with confidence. What you will learn: Understand the mechanics of passive and active cellular transport processes; Explain the generation of resting membrane potentials and action potentials in excitable tissues; Analyze the physiological structure and function of nerve fibers and neuromuscular junctions; Master the molecular mechanisms of skeletal and smooth muscle contraction; Apply physiological principles to modern clinical concepts, including channelopathies and neuromuscular disorders. The course begins with essential terminology and foundational biophysical concepts before progressing systematically through nerve signaling, muscle excitation-contraction coupling, and modern clinical correlations. Designed specifically for beginners, pre-med students, and biology enthusiasts, this course requires no prior advanced medical background.
