LO2: know The structure and functions of the muscular system
Content and assessment criteria
• Types of muscle tissue
• Basic structure of skeletal muscle
• Name and location of skeletal muscles
• Function of muscle
• Muscle contraction and action
• Skeletal muscle fibre types and their characteristics
The muscular system is the system responsible for creating movement and motion and maintaining
posture.
Muscle Function
• Movement;
• Heat production;
• Muscle contraction;
• Sliding filament theory (actin, myosin, sarcomere, troponin, tropomyosin, calcium, ions, ATPase)
• Skeletal muscle roles (antagonistic pairs, fixators, synergists)
Types of muscle tissue
● Cardiac (myocardium), e.g. the heart.
● Smooth e.g. the digestive system.
