4.1.List of study practical tasks necessary to perform at the practical class.
Materials and methods: vertical myograph, stimulator, irritating electrodes, kymograph, strand, preparation instruments set, gauze napkins, Ringer’s solution.
Investigatioin object: frog.
Task 1. Skeletal muscle contractions curves registration
To prepare nervous-muscular preparation, to fix it in myograph and to bring the electrodes from constant current electrofeeding source. To irritate the muscle with separate key blow and to registrate (write) separate muscular contraction curve. The velocity of kymograph drum must be maximal. Mark the separate muscular contraction phases and their duration.
Infused (incomplete) tetanus. Right after the separate muscular contraction curve the investigator performes 10-20 fast going one after another key closing and unclosing. As a result imperfect, incomplete summation of separate muscular contractions - infused (incomplete) tetanus – occurs.
Smooth (complete) tetatus. For its receiving the muscle must be irritated with high frequency – 50 oscillations per second. Electrods must be brought to the unconstant current electrical feeding and the key must be closed in course of 2-5 seconds.
To measure the altitude of single muscular contraction, infused and smooth tetanus curves received at equal stimulus force.
To glue the curves received into copy-books. To make the conclusions.
Task 2. Dynamometry
The investigated person is asked to sit on the chair and to stretch his arms forward and to pressure dynamometer maximally with a hand. Every hand muscular force should be estimated 3 times.
The results should be written in a copy-book.
