Cardiomyocytes - Everything You Need to Know

Dive into a comprehensive 33-minute video lecture on cardiomyocytes, covering everything from basic concepts to advanced physiological processes. Explore the three main types of cardiac muscle cells - pacemaker, contractile, and endocrine - and their unique functions within the heart. Understand the intricacies of the heart's conduction system, including the roles of the SA node, AV node, and Purkinje fibers. Compare and contrast the action potentials of pacemaker and contractile cells, examining each phase in detail. Learn about the electrical conduction pathway, refractory periods, and key properties of cardiomyocytes such as automaticity and the all-or-none law. Gain insights into cardiac physiology through a structured syllabus, preparing you for a quiz to reinforce your understanding of this crucial aspect of cardiovascular function.
