Summary Introduction
Introduction: A membrane-bound structure called sarcoplasmic reticulum is a specialized, smooth endoplasmic reticulum that mainly functions in the regulation of calcium ions that are present in the striated muscle cells. Calcium is a mineral that is mostly found in teeth and bones and provides them strength.
