  • Four properties of muscles: Excitability, Contractility, Extensibility, Elasticity
  • Three types based on location: Skeletal, Visceral (Smooth), Cardiac
3

Structure of Skeletal Muscle

  • Muscle → Muscle bundles (fascicles) → Muscle fibers → Myofibrils → Myofilaments
  • Fascia: Collagenous connective tissue holding muscle bundles together
  • Muscle fiber is a syncytium (multinucleated) enclosed by sarcolemma
4

Molecular Structure of Muscle Proteins

  • Actin (thin filament): Made of F-actin (filamentous) which is polymer of G-actin (globular)
  • Tropomyosin runs along F-actin throughout its length
  • Troponin complex distributed at regular intervals on tropomyosin
