Unit 6:5 Muscular System Exam with
Complete Solutions
Excitability - ANS-Ability to respond to a stimulus.
Extensibility - ANS-Ability to be stretched.
Contractability - ANS-Ability to become short and thick.
Elasticity - ANS-Ability to return to its original shape.
Quadriceps femoris - ANS-Muscle on front of thigh that extends leg.
Muscle Spasms - ANS-Sudden, painful, involuntary muscle contractions.
