The Muscular System:Skeletal Muscle Tissue

The Muscular system of rules Skeletal heftiness builder Tissue interest in the characteristics of the three bodybuilder types Muscle Type Cardiac Shape of stall Skeletal branching chains of cells single, pertinacious cylindrical of nuclei 15 um in diamter, flyspeck Striations yes, has myofibrils and sarcomers Control in spontaneous 100 um In size, big Smooth single, spindle image cells 2-10 In diameter, medium yes, presences of myoflbrilsno presence of myofibrils and sarcomeres voluntary tendons What attaches musculuss to bone? 3. The whole muscle is serene of muscle cells (fibers) grouped in bundles called fascicles 4.Name the connexion tissue coverings surrounding the following whole muscle epimysium perimysium Fascicles endomysium Muscle cell 5. agree the following three terms with their definitions 2 Sarcolemma Sarcoplasmic reticulum Cytosol 6. endoplasmic reticulum in muscle cell 3 intracellular fluent around organelles plasma membrane of muscle cell Terminal cisternae T-tubules 2 troika 1 7. part of sarcolemmacarries action potentiality part of sarcoplasmic reticulumstores calcium ions Myofibrils comprise of contractile proteins calledName the devil types and what theyre composed of stretch filaments composed of protien actin protien myosin thick filaments 8. . microfilaments Arrangement of myofilaments. tumble the letter name of each caboodle Dark echo + A tintinnabulation Light band + band advert dickens definitions with each band contains just now sensitive filaments A contains specify by length of thick filament A defined 9. both thick and thin filaments as distance between devil thick filaments Z line (disc) defined by length of thick filament, A band the H regularises lies within the A band where the thick filaments are H zone 10.What happens to these areas during contraction? the z- lines move tightfitting Z line (disc) H zone the h zone will lesson in width during the contraction 11. Define these two terms th is is a thin or a fine band that is unconsolable and will cross over into the condense of the M line A band 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. consecrate the following components in order, from smallest to largest 6 fascicle 2 muscle myofibril 4 myofilament 5 muscle 1 muscle fiber.
