4. An oscilloscope: a. Provides stimulus to a tested muscle b. Adds weight (load) to a tested muscle c. Measures a twitch response of a tested muscle d. A and C e. All of the above 5. At the point of muscle overload: a. Skeletal muscle contracts steadily (tetany) b. Skeletal muscle contracts and relaxes repeatedly c. Skeletal muscle does not contract at all 6. A skeletal muscle’s “threshold of stimulation”: a. Is determined by the lowest voltage stimulus needed to elicit a muscle twitch b. Varies with muscle type c. Is not altered by the application of muscle load d. B and C 7. In response to a stimulus, skeletal muscle fibers: a. Always contract to 25% of their potential ability b. Always contract to 50% of their potential ability c. Always contract 100% of their potential ability d. None of the above 8. Based upon your experimental data, which muscle type exhibited the lowest threshold of stimulation in all conditions tested? a. Lower forelimb muscle b. Upper forelimb muscle c. Calf muscle d. Thigh muscle 9. Based upon your experimental data, which muscle type(s) did not reach the point of muscle overload? a. Lower forelimb muscle b. Upper forelimb muscle c. Calf muscle d. Thigh muscle Title: Re: Lab 8 Post by: MedicLife on Jun 18, 2011 4 D
