Muscles and Movements

Structure of muscles

• actin and myosin
• Vertebrate striated muscle
• Cardiac muscle

Energy for contraction

• Sliding filaments and the mechanisms of contraction.
• ATP and creatinine phosphate
• Troponin, tropomyosin and calcium

Initiation of contraction

• Muscle potentials

The sarcotubular system

• The sarcoplasmic reticulum

How muscles work, contraction

• Isometric contraction
• Isotonic contraction
