a.  
b.  
c.  
d.  

#### 21. Would you expect to find larger motor units in the postural muscles of the back or the muscles of the hand? Explain your answer.

#### 22. What conditions does excess post-exercise oxygen consumption help to correct?

#### 23. What are the two types of smooth muscle? How are they different? Give an example of each in the body.
