The Muscular System:Skeletal Muscle Tissue

The Muscular System atrophied brawn-builder Tissue Fill in the characteristics of the third muscle types Muscle Type Cardiac Shape of prison cell Skeletal branching arrange of cells single, long cylindrical of nuclei 15 um in diamter, small Striations yes, has sarcostyles and sarcomers Control goaded 100 um In size, big Smooth single, spindle 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 whole muscle is compose of muscle cells (fibers) grouped in bundles called fascicles 4.Name the connective tissue coverings surrounding the succeeding(a) Whole muscle epimysium perimysium Fascicles endomysium Muscle cell 5. Match the following three terms with their definitions 2 Sarcolemma Sarcoplasmic reticulum Cytosol 6. endoplasmic reticulum in muscle cell 3 intracellular fluid around organelles plasma membrane of muscle cell Terminal cisternae T-tubules 2 Triad 1 7. part of sarcolemmacarries satisfy potential part of sarcoplasmic reticulumstores calcium ions Myofibrils consist of contractile proteins calledName the dickens types and what theyre composed of thin filaments composed of protien actin protien myosin dumb filaments 8. . microfilaments Arrangement of myofilaments. Give the earn name of each tidy sum Dark dance chevron + A band Light band + band Match twain definitions with each band contains only thin filaments A contains out grapevined 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 inside the A band where the thick filaments are H zone 10.What happens to these areas during concretion? 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 center of the M line A band and has striated fiber muscles are muscles that have two meaning(a) filaments, thin and thick. they lie in between Sarcomere bands 12. the two z- Organization of muscle. regulate the following components in order, from smallest to largest 6 fascicle 2 muscle myofibril 4 myofilament 5 muscle 1 muscle fiber.
