9. When a muscle fiber is subjected to very frequent, continual stimuli
- It stops responding after a certain period.
- It goes into oxygen debt.
- It begins to twitch.

11. Which type(s) of muscle lacks striations?
- Skeletal only.
- Skeletal and cardiac.

A. Protein. B. Carbohydrate C. Lipid D. Nucleic Acid E. A and C
14. After the biceps brachia contract, how do they expand again?
- The nervous system tells it to expand to its full length.
- It relaxes and then expands naturally.
- Smooth muscle contracts, pulling it back to its full length.

24. Most of the lactic acid that has been built up when you exercise is
- Broken down and reused.
- Is distributed to the rest of your body.
- Stored as fat
- Used as a building block for proteins.
- All of the above.
25. The striations seen in some types of muscle tissues are due to
- Different amounts of myoglobin.
- Arrangement of proteins within cells.
- Arrangement of blood vessels in cells.
- Types of cell junctions.

- Skeletal muscle.
- Smooth muscle.
- Cardiac muscle
- Both cardiac and smooth muscle.
- None of the above.
27. Smooth muscle is found :
- Attached to bone.
- Lining hollow organs and body tubes.
- In the wall of the heart.
- Lining long bones.
- B and C
28. Myosin is found in
- Thick filaments. B.Thin filaments C.The sarcoplasmic reticulum D. A and C
29. The sliding filament theory of muscle contraction says:
- Actin filaments become shorter when they combine with myosin.
- Myosin rotates and has actin wrap around it.
- Friction is reduced between thin and thick filaments causing thick to move, inside the thin.
- Myosin filaments slide between the actin, making the muscle shorter.
- A neurotransmitter alters the arrangement of collagen fibers in the endostium, causing it to shrink.
30. Which of the following statements is false?
- Muscles convert mechanical into chemical energy
- Cardiac muscles are short, and web like
- Smooth muscles move food by squeezing the intestines like a tube of tooth paste.
- Skeletal muscles are multinucleated.
- Cardiac muscle never rests.
31. A sphincter is what sort of muscle?
- Skeletal.
- Nervous
- Cardiac
- Smooth
- Depends on where it s located.
33. Skeletal muscles are dependent on what to contract?
- Actin
- Myosin
- A nerve impulse
- Ions
- Protein
34. What happens to the cell membrane of muscle when it contracts?
- It actively pumps Sodium ions to a lower concentration.
- It allows Sodium ions to flow to a lower concentration ,
- It prevents Sodium from entering the cell,
- It polarizes and shortens
- A and C
35. All or none response refers to what
- Ability of a neuron to excite several muscles at once.
- Ability of several muscles to contract at once.
- All fibers within a muscle cell contracting at once or not contract at all.

B. Stabilizing body positions
C. Regulating organ volumes
D. Producing heat by shivering
- E. Breathing
