troponin
tropomyosin
actin
myosin
Calcium is stored in the ___.
sarcoplasm
sarcolemma
sarcoplasmic reticulum
transverse tubules

Label the types of muscle tissue
Smooth
Skeletal
Cardiac
Label the parts of the thin filament
Actin
Tropomyosin
Troponin complex
What is being released from the axon which will help stimulate an action potential that travels along the sarcolemma and into the transvers (T) tubules?
Calcium
Estrogen
Epinephrine
Acetylcholine (neurotransmitter)
The binding of calcium to troponin signals tropomyosin to do what?
What creates the powerstroke in a muscle contraction?
Elongation of the sarcomere
Sliding of thin actin over the thick myosin filaments
After the powerstroke, the actin-myosin cross-bridge remains intact until an ____ binds to the myosin head. After this, the myosin will detach from actin.
