Lectures
Dear Students, all Lectures will be in Presence Form.
All online lectures will be available in the program MS Teams.
Team - Biophysics MF CU Bratislava (channel Lectures)
Spoken lectures will always be published at the beginning of the week according to the topics listed in the lecture schedule.
Schedule of the lectures
| 1. | Introduction to teaching. Transport processes – active and passive transport, diffusion (1st and 2nd Fick's law), osmosis, filtration, adsorption. Resting and action membrane potential - generation and propagation of action potential, myelinated vs. unmyelinated fiber, graded potential vs. action potential, heart action potentials. |
| 2. | Biomechanics of blood circulation - physical laws related to blood flow, pressures, flow rate, resistance, blood flow, elastic effect, pulse wave, blood pressure measurement (methods: auscultatory, oscillometric, ultrasound). |
| 3. | Electrical diagnostic methods (ECG, EEG, ECoG, ERG, EMG, EGG). |
| 4. | Radioactivity - laws, units, half-life (physical, biological, effective), natural and artificial radioactivity. Types of alpha, beta, and gamma decay. Interactions of ionising radiation with matter. |
| 5. | X-ray radiation. Biological effects of ionizing radiation, protection against ionizing radiation. Detectors of ionising radiation. |
| 6. | Laws of light propagation in an optical environment. Biophysics of visual perception. Optical and electron microscopy. |
| 7. | Sound and ultrasound – properties. Imaging using ultrasound. |
| 8. | Electromagnetic spectrum, non-ionizing radiation - light, infrared (Stefan-Boltzmann law, Wien displacement law). Electric current - direct current, alternating current, measurement, effects of current, safety (microshock, macroshock), faradic and galvanic currents. |
| 9. | Imaging methods in medicine (X-ray, CT, MR, PET, SPECT). |
| 10. | Fundamentals of mechanics (speed, acceleration, acting forces). Effects of mechanical and acoustic factors on the organism, sedimentation. |
| 11. | Biomechanics of movement, principle of lever, mechanical properties of tissues, Hooke's law. Biophysics of auditory perception. |
| 12. | Biomechanics of respiration - respiratory function, air flow - pressure gradient, respiratory resistances, retraction forces, surface tension, pneumothorax, alveolar pressure, interpleural pressure, diffusion rate, partial pressures, solubility of gases in the blood. Information about the exam. |
