Aim/objectives: to introduce students to the theory of electrical phenomena at the cell, organ and organism level, to
the possibilities of measuring and using these manifestations. A sub-objective is to enable students to experimentally verify the
This course builds on Anatomy and Physiology I and II and requires a basic
knowledge of the structure (anatomy) and function (physiology) of the following systems (excitable tissues): nervous, musculoskeletal, circulatory
(especially the heart).
The course deals with the problems of excitable tissues (nervous,
The course deals with the physiology of nervous tissue, muscle and glandular tissue and provides knowledge of the physiology of electrical processes at different levels: cell, tissue, organ, organism.
Conditions for the award of credit: attendance and reports from practical training, without the award of credit the student will not be admitted to the examination.
Examination: written test, questions include numerical problems or require a complex approach to solving. The number of questions is 20. 60 minutes are allotted for the test. Writing test with a minimum of 50%. Overall grade according to the ECTS classification table.
