Chapter 12.3, Problem 30CC
Summary Introduction
To compare: The Ca2+ release channels in skeletal and smooth muscle sarcoplasmic reticulum.
Introduction: The cells present in the muscles are called muscle cells. The muscle cells contain a high concentration of Ca2+ ions. The role of these ions is to help in the contraction and relaxation of muscles. The muscles are divided into three types. These are smooth muscles, cardiac muscles, and skeletal muscles.

Discuss the similarities and differences by which Ca2+ activity is involved in initiating muscle contraction in skeletal versus smooth muscle fibers (hint: include Ca2+ sources, proteins it binds to, and signaling cascade it activates leading to contraction).
List the four primary signal transduction pathways in skeletal muscle.
Describe the regulation of smooth muscle contraction by intracellular calcium and how cross-bridge cycling is terminated when calcium decreases again.
