Skeletal Muscle Microscopic Anatomy Chapter 10 Microscopic Anatomy Muscle fibers = muscle

cells: long and multinucleate Sarcolemma: cell membrane Sarcoplasm: cytoplasm; rich in oxygen-storing myoglobin protein Myofibrils: bundles

of contractile proteins; fill most of the cytoplasm; 100s to 1000s per cell Sarcomeres: the repeating functional unit of contraction in each myofibril

T tubules (transverse tubules): narrow tubes that are continuous with sarcolemma, conduct impulses Sarcoplasmic reticulum (smooth ER): stores Ca+ + (muscle contraction begins when stored Ca++

ions are released into sarcoplasm) Mitochondria: provide ATP for contraction Closer Look at Myofibril Composition thin filaments: actin (plus

tropomyosin & troponin) Fig. 10.5 thick filaments: myosin Sarcomere Structure

Z lines: the boundary between sarcomeres A band: overlap of thick (myosin) filaments & thin (actin) filaments I band: thin (actin) filaments only H zone: thick (myosin) filaments only
