Arrange the following actions chronologically as contraction occurs.

*The T-tubules depolarize causing calcium to be released from the sarcoplasmic reticulum.

*Calcium is resequestered (taken up) into the sarcoplasmic reticulum.

*Tropomyosin moves exposing the actin active sites.

*The innervating alpha-motorneuron has an action potential.

*The binding of acetylcholine causes a skeletal sarcolemma to have an action potential.
