Presentation Transcript
slide1. Effect of various strength of stimuli on skeletal muscle contraction Dr. Jharashree.K. Sahoo
Assistant Professor<br>
slide2. Which property it proves? Presence of Motor Units in the muscle.
All or None Law<br>
slide4. Motor Unit The neuron, nerve fibers and muscle fibers supplied by the nerve fibers are called motor unit.
No. of muscle fibers in a motor unit varies inversely with the precise movement of the body part.
Muscles of hand, muscles concerned with eye movement--- 3-6 ms. Fibres /motor unit
Back and Leg muscles– 120-165ms. Fibres /motor unit<br>
slide6. All or None Law If the strength of stimulus is adequate the muscle fibres show the response --- All phenomenon
If the strength of stimulus is not adequate muscle fibres do not show any response at all---- None phenomenon
It is obeyed by the skeletal muscle by individual muscle fibre and cardiac muscle as a whole.<br>
slide7. Types of Stimuli Subminimal
Minimal
Submaximal
Maximal
Supra Maximal<br>
slide8. Effect of various strength of stimuli on skeletal muscle contraction<br>
slide9. Make
Break
Why Break stimulus is effective first than make?<br>
