Gross Anatomy of Skeletal Muscle Muscle fiber Endomysium Fascicle Perimysium Epimysium Deep facia

Connective Tissue Sheaths Endomysium Perimysium Epimysium Collagen fibers of all 3 layers come together at each end of muscle to form a tendon or aponeurosis.

Microscopic Muscle Fiber Anatomy Sarcolemma - ‘cell membrane’ Sarcoplasm - ‘cytoplasm’ Myoglobin** Transverse tubules Sarcoplasmic Reticulum Myofibrils A band I band

Myofibril Myofilaments Two types Actin (+ 2) filaments (thin filaments) Myosin filaments (thick filaments)

Sarcomere Between 2 Z-discs Contractile Unit Sarcomere + sarcomere + sarcomere = myofibril A band

I bands

Z lines Sarcomere

Actin and Myosin Filaments

Myosin (Thick) Filament 1 protein Generates tension

Actin (Thin) Filament Three proteins Actin (contractile) Troponin (lock) Tropomyosin (door)

axon T tubules myofibrils sarcomere plasma membrane
