1 Anatomy and Physiology Journal Ch 6

2 What are the three types of muscles? Skeletal Skeletal Cardiac Cardiac Smooth Smooth

3 Which muscle types are striated? Cardiac Cardiac Skeletal Skeletal

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

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

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

9 What is a muscle group that works with and assists the action of a prime mover? synergist synergist

10 What are the four abdominal muscles? rectus abdominis rectus abdominis external oblique external oblique internal oblique internal oblique transverse abdominis transverse abdominis
