The lecture on cell membrane potentials is a fundamental topic in physiology and biochemistry. The Hodgkin-Huxley model is a mathematical model that describes the ionic currents that flow across the membrane of a neuron. The model is based on the idea that the membrane potential is determined by the movement of ions, such as sodium and potassium, across the membrane.The change in membrane potential can be described by the following equation: where is the change in membrane potential, is the resting membrane potential, and is the membrane potential at a given time.The gas equation, which describes the movement of ions across the membrane, is given by: where is the flux of ions, is the initial concentration of ions, is the Boltzmann constant, is the temperature, is the concentration of ions, and is the charge of the ions.The Theorell equation, which describes the distribution of ions across the membrane, is given by: where is the sum of the transmembrane potentials.The Nernst equation, which describes the relationship between the membrane potential and the concentration of ions, is given by: where is the resting membrane potential, is the concentration of ions at the membrane, and is the Henry constant.Overall, the lecture on cell membrane potentials provides a comprehensive understanding of the mechanisms that govern the movement of ions across the membrane and the resulting changes in membrane potential.
