• Where are cardiac muscles located?

  In the walls of the heart
• What is the function of cardiac muscles?

  They help in the contraction of heart walls
• How do cardiac muscles differ from skeletal muscles?

  Cardiac muscles are involuntary in nature
• What is the role of fixator muscles?

  Stabilize the origin of the agonist muscle
• How do fixator muscles assist during movement?

  They stabilize one part of the body
• What are synergist muscles?

  Muscles that stabilize a joint during movement
• How do synergist muscles assist agonist muscles?

  They help the agonist muscle contract
