Joints and Muscle Tissue Study Guide

Joints, Muscles, and Muscle Tissue Study Guide

1. Be able to tell if an exercise I describe is eccentric or concentric, isotonic or isometric
2. Know the characteristic of skeletal vs. cardiac vs. smooth muscles from the first few pages of the chapter
3. Know the structural and functional classifications of joints, their characteristics, components and examples of each
4. Be able to compare and contrast the three general types of arthritis.
5. Know the connective tissue sheaths present in skeletal muscle, and what they surround.
6. What happens to the different regions/bands/zones/discs during a muscle contraction. For example: The I bands shorten when a muscle contracts.
7. What are t tubules? What do they do?
8. What is a motor unit?
9. Know the 4 properties of muscle tissue and what they do
10. What causes muscle fatigue
11. Know the three ATP production Pathways, when they are used, how they work, etc.
12. What is the difference between an intracapsular ligament and an extracapsular ligament, and what are some examples of each
13. Which muscle fibers would we expect to have a higher mitochondrial density
14. What does tropomyosin do? What does troponin do?
15. What is the size principle?
16. What chemical is released at the neuromuscular junction that triggers the formation of an end plate potential
17. Which joints are more likely to dislocate?
18. When would we expect the intracellular concentration of calcium to rise?
19. What is the fuel source for muscle contraction
20. At what length can muscle produce the greatest amount of tension (Answer: 80-120% of resting length)
21. What is the sarcomere?
22. Know how many degrees of freedom the different joint have. A joint has one degree of freedom for every axis it can rotate around
23. What covers the articular surfaces of joints
24. What planes do the different motions occur in
25. In what position are the knee and hip ligaments the tightest
26.  What is a muscle twitch?
27. Read the motor unit section
28. What are most joints of the limbs classified as?
29. What motions can each joint perform?
30. Read the fiber type section and adaptation to exercise section.
31. Be able to explain in depth how a stimulus from a motor neuron can ultimately produce a muscle contraction
