UNIT OBJECTIVES

After completing this unit, you should be able to:

  • Name the major differences between the three types of muscles
  • Name the major parts of a skeletal muscle fiber and describe the function of each part
  • Explain the functions of myosin and actin in the muscle contraction
  • Explain how oxygen debt develops and how a muscle may become fatigued
  • Explain what is meant when muscles are called prime movers, antagonists, or synergists
  • Describe the types of movements that occur at freely movable joints
  • Identify and describe the location of the major skeletal muscles of each body region
  • Identify muscular diseases, causes and symptoms
  • State the meanings of the prefixes, suffixes and root words of this unit

Get Body Smart

Click on the web address above and work through the various muscle tutorials. You may have to substitute some of the names we used in class for the ones on the diagram. Be sure to click on the muscle parts that you wish to identify.

STUDY TIPS

  • Learn the muscles in respect to the bones. Many have the same names or words that are similar to the bones.
  • Study your notes early. Don't wait until the last minute to get the terms straight in your head. It will only make learning the muscle names more difficult.
  • As in any unit, be sure to read the chapter, go over the outline and objectives, and check your knowledge by doing the quiz at the end.
  • Learn the diagrams at home and then compare them to the models at school. Don't try to learn all of the muscles in the ONE class period.

TEST QUESTIONS WHAT TO STUDY
1-38 Matching muscular terminology Notes and muscular lab
40-60 Muscle function Muscle Lab
61-70 Body Movements Review your body movement lab from skeletal system
20 pts. Constructed Response Prefixes, Suffixes and Root words; how a muscle contracts; thinking skills

 

TEST REFLECTION

  1. How did you do on this test in comparison to the skeletal test?
  2. Why do you think it was easier to study the muscles than the bones?
  3. What study skills have you begun to develop that you did not have before?
  4. What study skills do you still have to develop?
