The Muscular System:Skeletal Muscle Tissue

The brawny System penurious Muscle Tissue Fill in the characteristics of the tierce muscularity types Muscle Type Cardiac Shape of cell Skeletal branching chains of cells single, long cylindrical of nuclei 15 um in diamter, atrophied Striations yes, has myofibrils and sarcomers Control involuntary 100 um In size, big Smooth single, bower shape cells 2-10 In diameter, medium yes, presences of myoflbrilsno presence of myofibrils and sarcomeres voluntary tendons What attaches muscles to bone? 3. The consentient muscle is composed of muscle cells (fibers) grouped in bundles called fascicles 4.Name the connective waver coverings surrounding the following Whole muscle epimysium perimysium Fascicles endomysium Muscle cell 5. suffer the following three terms with their definitions 2 Sarcolemma Sarcoplasmic reticulum Cytosol 6. endoplasmic reticulum in muscle cell 3 intracellular fluid around organelles plasm membrane of muscle cell Terminal cisternae T-tubules 2 Triad 1 7. part of sarcolemmacarries action potential part of sarcoplasmic reticulumstores calcium ions Myofibrils rest of contractile proteins calledName the ii types and what theyre composed of thin filaments composed of protien actin protien myosin slow filaments 8. . microfilaments formation of myofilaments. Give the letter name of each round Dark pot + A band Light band + band Match dickens definitions with each band contains only thin filaments A contains defined by length of thick filament A defined 9. both thick and thin filaments as distance between two thick filaments Z line (disc) defined by length of thick filament, A band the H zones lies within the A band where the thick filaments are H zone 10.What happens to these areas during abridgement? the z- lines move close Z line (disc) H zone the h zone will lesson in width during the contraction 11. Define these two terms this is a thin or a fine band that is dark and will cross over into the ca-ca-to doe with of the M line A b and and has striated fiber muscles are muscles that have two important filaments, thin and thick. they lie in between Sarcomere bands 12. the two z- Organization of muscle. Put the following components in order, from smallest to largest 6 fascicle 2 muscle myofibril 4 myofilament 5 muscle 1 muscle fiber.
