In this episode of Physiology Roundtable, we focus on one of the most critical aspects of cell function: the plasma membrane. Often underestimated, this dynamic structure governs transport, signaling, and homeostasis. Join us as we explore how gradients, ion channels, and membrane potentials shape everything from nerve impulses to nutrient absorption. 🎯 Learning Objectives: By the end of this episode, listeners will be able to: Describe the structure and function of the plasma membrane and its components. Explain how gradients and membrane potentials are established and maintained. Identify different types of membrane transport: passive, facilitated, active, and vesicular. Understand the physiological significance of ion channels and membrane excitability.

In this electrifying episode of Physiology Roundtable, we explore how cells generate, maintain, and propagate electrical signals — the basis for everything from heartbeat to brain function. Join us as we demystify membrane potentials, action potentials, and the exquisite timing that allows neurons and muscles to function in perfect synchrony. 🎯 Learning Objectives: By the end of this episode, listeners will be able to: Define resting membrane potential and describe how it is established and maintained. Describe the phases and ionic basis of an action potential. Understand how action potentials propagate along axons, including saltatory conduction. Recognize how electrophysiological principles apply to neural signaling, cardiac function, and muscle activation.

In this episode of Physiology Roundtable, we zoom in to the microscopic level to explore the cell — the fundamental unit of life and function. Join our hosts as they uncover how cells generate energy, communicate, transport materials, and maintain their internal environment. Whether it's ion pumps, membrane potentials, or intracellular signaling, this deep dive into cellular physiology lays the groundwork for understanding every system in the body. 🎯 Learning Objectives: By the end of this episode, listeners will be able to: Describe the structural and functional organization of a typical human cell. Explain how cells maintain homeostasis through membrane transport and organelle function. Understand the role of ATP, mitochondria, and metabolic pathways in cellular energy production. Identify key mechanisms of cell communication and signaling pathways.

In this inaugural episode of Physiology Roundtable, our trio of expert hosts lay the groundwork for the entire series by exploring what physiology truly is — beyond textbook definitions. With engaging insights, real-world analogies, and clinical relevance, we uncover how physiology serves as the dynamic language that connects all living systems. Whether you're new to the field or revisiting core concepts, this episode will orient you to the principles, scope, and central importance of physiology in understanding health and disease. 🎯 Learning Objectives: By the end of this episode, listeners will be able to: Define physiology and distinguish it from related disciplines like anatomy and biochemistry. Describe the hierarchical organization of the human body from molecules to organ systems. Understand the significance of homeostasis and control mechanisms. Recognize the integrative nature of physiology in health, adaptation, and disease.
