Objectives-2, BIO 2310, Muscle Tissue


1. List the characteristics and overall functions of muscle tissue.

2. Compare the location, microscopic appearance, nervous control, and functions of the 3 kinds of muscle tissue.

3. Define fascia, epimysium, perimysium, endomysium, fascicle, tendon, and aponeurosis.

4. Explain the relationship of blood vessels and nerves to skeletal muscle.

5. Describe the microstructure of skeletal muscle, including: sarcolemma, myofiber, myofibril, myofilament, A band, I band, Z line, sarcomere, actin, myosin, sarcoplasmic reticulum, tropomyosin, troponin, transverse (T) tubules, and terminal cisternae.

6. Describe the principal events associated with the sliding-filament theory.

7. Describe the structure and importance of a neuromuscular junction (motor end plate) and a motor unit. What is acetylcholine?

8. Describe why calcium regulates contraction.

9. Describe ATP sources for skeletal muscle contraction.

10. Describe restorative processes following strenuous exercise.

11. Describe the cause of muscle fatigue.

12. Describe the phases of contraction in a typical myogram of a twitch contraction.

13. Define the all-or-none principle of muscular contraction.

14. Explain how WHOLE muscle responses are graded contractions to meet the demands of the task at hand.

15. Define multiple motor unit summation, spatial summation, temporal summation, wave summation, incomplete tetanus, complete tetanus, treppe, asynchronous motor unit summation and muscle tone.

16. Contrast isometric and isotonic contractions.

17. Compare the structure and function of the 3 types of skeletal muscle fibers [slow, intermediate, fast].
