What is the first step in the muscle contraction process?

• A action potential releases calcium ions, so the synaptic vesical release Acetylcholine

• discharged calcium ties with troponin which pulls tropomyosin fibers out of the way uncovering the myosin authoritative locales on the actin fiber

• The action potential comes to the transverse tubules and causes the sarcoplasmic reticulum to discharge put away calcium ions into the sarcoplasm

_ is stacked in layers, in tightly packed cells, that creates a barrier for safety.
