• soft tissue in most plants

• soft tissue in most animals

• cardiac

• skeletal

• hard dermal

• smooth

muscles` main job is helping bones

• TRUE

• FALSE

the ....... tissue is only found in one organ and helps in pumping blood

• cardiac

• smooth

• dermal

• each muscle work individually, contracting and relaxing whenever it can

• they work in pairs, relaxing and contracting at the same time

• they dont work

name the muscle tissue that works involuntary

which one is wrong

• cardiac tissue -----> heart

• smooth tissue --------> blood vessels and triceps

• skeletal tissue --------> biceps

• none is wrong

how does the sliding filament theory work

• thick and thin filaments slide over each other leading to a contract of muscles

• contracting muscles lead to thick and thin filaments sliding over each other

• contracting muscles lead to relaxing in the filaments

• changing appearance of cell leads to sliding of thick and thin filaments over each other

what are myosin and actin filaments

• myosin is the thin and actin is the thick filaments

• myosin is the thick and actin is the thin filaments

• both are thick filaments

• both are thin filaments

what are myofibrils

• 1000s of fibers

• 1000s of tissues

• 1000s of muscles

• 1000s of cells
