Question
Chapter 12, Problem 30RQ
Summary Introduction
To determine: The reasons that influence the entry and release of Ca2+ ions in smooth muscle fibers.
Introduction: The sarcoplasmic reticulum is the modified form of the endoplasmic reticulum. The amount of SR in smooth muscle cells varies from one type of smooth muscle to another.
