A. Identify the structure indicated by the blue arrows.
B. It contains a structure that is important for propagation of action potential in the cardiac muscle. What is it known as?
A. Intercalated discs
B. Gap junctions
A. Identify the structure within the dotted area
B. Why does it stain pale when compared to cardiac muscle?
A. Purkinje fibers
B. Large, clear cytoplasm contains lots of glycogen and less protein so it stains lighter
