Chapter 9 Muscle Structure and Physiology 
 
 

Chapter 9:  Muscles

 

Test Concepts and Key Objectives
1.  Muscle function

2.  Compare and contrast:  skeletal, cardiac, smooth

3.  Muscle anatomy:  muscle, fascicle, muscle fiber, myofibril, sarcomere, myofilaments (some labeling of diagrams)

4.  Neuromuscular junction (acetylcholine, little on action potential Na, K pump (to be covered with nervous system), effect on sarcoplasmic reticulum)

5.  Muscle metabolism:  ATP production (creatine phosphate, glycolysis, cellular respiration)

6.  Muscle fiber types (red, white) differences

7.  Muscle tone, isotonic contractions, isometric contractions 

 

Writing Prompt

1.  Essay on Test and option on Final:  Big Essay (take time, make outline) 

Explain the sliding filament theory of contraction when thin filaments slide over thick filaments to produce active shortening of muscle fiber.  Terms to include but not necessarily all terms (actin, myosin, troponin, tropomyosin, calcium ions, ATP, ADP, Pi (inorganic phosphate), cross bridges)

2.  Make a comparative chart for the three different types of muscle tissue:
  Striated or not Voluntary or Involuntary Where found
skeletal      
smooth      
cardiac      

3.  What are five functions of the muscular system?

4.  Label the parts of the sliding filament model.  See website below
