There are three types of
muscle in the human body: Skeletal, Cardiac, and Smooth muscle. Only
skeletal muscle is voluntary. Both skeletal and cardiac muscle are
striated, meaning that one can see alternating bands of light and dark.
Regardless, all muscle exhibits the following characteristics:
-
Excitability:
o
All are capable of responding to a stimulus.
-
Contractility:
o
All have the capacity to shorten and generate
force.
-
Extensibility:
o
All have the ability to be stretched.
-
Elasticity
o
All have the ability to return to resting
length after being stretched. |
