Action potential.2. Propagation of nervous impulse. 3. Mechanism of generation and propagation of action potential. 4. Telegraph equation. 5. Reliability factor. Break - 10 minutes Learning and teaching methods: - analysis and discussing of main and control questions; - solving of standard and situational problems; - testing; - correction of mistakes. Methods of the control of formed at classes competencies: - checking of the solution of standard and situational problems; - opinions exchanging at the studying of educational material; - testing on a computer (a student has to give the answers for test questions that contain minimal knowledge and skills – main definitions, theoretical questions of the theme). Students’ independent work - 25 minutes · Explain the context and find the ways of solving the problems. · Transform the formula and convert the unit of physical quantities to the International System of Units. · To find the ways of solution of given problems Problems: 1. At what distance х in unmyelinated nervous fiber the transmembrane potential difference 2. Transmembrane potential difference in unmyelinated nervous fiber decreases in two times at 3. Calculate the diameter D of axon if the electrical resistivity of the unit of membrane thickness is 4. In the place of unmyelinated nervous fiber transmembrane potential difference is
