4. Define Epimysium & Endomysium
Connective tissue ensheathing the entire muscle.
Endomysium
Thin connective tissue investing each muscle cell.

5. Contrast Isotonic to Isometric.
Isotonic- Muscle shortens
Isometric- Muscle does not shorten even though tension increases

6. Describe anaerobic glycolysis.
No oxygen used
Fastest pathway to regenerate ATP
30-60 seconds

7. Explain the condition of skeletal muscle fatigue.
It is caused by insufficient intracellular quantities of ATP due to excessive consumption.

8. List the functions of the muscular system:
production of movement
maintenance of posture
stabilization of joints
generation of heat
