General anatomy of muscle fibres

  • Sarcolemma - the plasma membrane in muscle fibre

  • Muscle fibres are multinucleotide - Being exceptionally wide and long, muscle fibres (0r cells) need many nuclei to regulate the metabolic demands of contractile proteins (e.g. actin and myosin)

  • Sarcoplasm - The protein filled cytoplasm of muscle fibres
