Chapter 10, Problem 7CP
Summary Introduction
To determine:
The region where the greatest concentration of Ca2+ is found in a resting skeletal muscle.
Introduction:
Skeletal muscle cells are cylindrical and long in shape and are multinucleated. They are mainly found attached to the bones with the help of tendons. The primary function of the skeletal muscle is in the movement and stabilization of the skeleton. These muscles help in insulation and also act as a protection for internal organs. These muscles are formed by the interlink age of actin and myosin filaments with proteins.
