There are 600 skeletal muscles that, through contractility, extensibility, excitability, and elasticity, are responsible for the movement of the body.
 
  Describe how contractility, extensibility, excitability, and elasticity are involved in muscular movement of the body.

Question 2

The suffix for disease is -pathy.
 
  Indicate whether the statement is true or false

Answer to Question 1

Contractility allows muscles to change shape to become shorter and thicker.
With extensibility, living muscle cells can be stretched and extended. They become longer and thinner.
In excitability, muscles receive and respond to stimulation.
With elasticity, once the stretching force is removed, a living muscle cell returns to its original shape.

Answer to Question 2

TRUE
