• A____duction: (as if lowering from side) motion toward the center.
Cardiac Muscle
• It forms the wall of the __________________. These, too, are ______________________ muscles.
• Muscle Movements: functional name comes from the type of movement it permits.– Ex. Flexor: permits bending (flexion)– Adductor: movement toward axis (adduction)– Circumductor: allows a circular motion (circumduction)
• Muscle Growth: Develops when existing muscle fibers ________________________. – Strength and size differ among individuals because of
