Muscle Contraction and Movement

Match the following types of muscles with their control mechanism:

Voluntary muscles = Perform voluntary contractions and relaxations Involuntary muscles = Perform involuntary contractions

Match the following actions with the appropriate muscle movement:

Bending the elbow = Brain instructs the triceps muscle to contract Straightening the arm = Brain signals the triceps muscle to relax

Match the following characteristics with the types of muscles:

Voluntary muscles = Work in coordinated groups with other muscles Involuntary muscles = Controlled by autonomic nervous system

Match the following with their locations in the body:
