Materials for auditory self-work.
4.1.List of study practical tasks necessary to perform at the practical class.
Materials and methods: vertical myograph, stimulator, irritating electrods, kymograph, universal stand, preparating instruments set, pipette, gauze napkin, Ringer’s solution.
Investigation object: frog.
Task 1. Isolated impulse conducting law (through nervous fibers).
The students must prepare the preparation of frog’s lower extremities with skin taking off and with 3 lower vertebras saving. You should ligatured each of nervous fibers at the place of sciatic nerve exit from the spine and to separate from the spine. Students must irritate every fibre of sciatic nerve one after another with weak electrical current, while observing different irritation phenomena at it.
Task 2. Two-sized conduction law.
Students must make frog’s extremity and preparated sciatic nerve so that not to hurt branchlets passing to the musculus quadriceps femoris and gastrocnemius muscle. One should irritate the nerve by electrical current near gastrocnemius muscle and observe the contraction both musculus quadriceps femoris and gastrocnemius muscle.
Task 3. Physiological integrity law.
Put the preparation on glass plate. To irritate the preparation nerve by electrical current. Frog’s leg is bended. To put the ligature on sciatic nerve. To irritate the nerve by electrical current again. The muscle doesn’t contract. If you attach the electrodes so that the ligature is between 2 electrodes the leg will be contracted. To repeat the examination but to use cotton wool tampon washed in novocain solution despite ligature.
Task 4. To study fatigue (tiredness) ability in synapse.
To prepare nervous-muscular preparation and to fix it into myograph. To irritate this preparation nerve with optimal frequency and force (voltage 1-5 V, frequency 50-100 Herz), to registrate myogram till tiredness becoming; to move electrodes to the muscle having increased the irritation force till optimum for tired muscle (10-20 V) and to continue to registrate myogram. The contraction altitude must get increased at it.
In conclusion: students must underline main synapses tiredness reasons and to mark that synapse is the most highly-tired structure in a whole central nervous system.
