Intercalated discs are microscopic identifying features of cardiac muscle. Cardiac muscle consists of individual heart muscle cells (cardiomyocytes) connected by intercalated discs to work as a single functional organ or syncytium.hree types of cell junction make up an intercalated disc â fascia adherens, desmosomes and gap junctions. 1  Fascia adherens are anchoring sites for actin, and connect to the closest sarcomere. 2  Desmosomes stop separation during contraction by binding intermediate filaments, joining the cells together.
Muscular arteries distribute blood to the skeletal muscles and internal organs. The tunica media of the muscular arteries have a higher percentage of smooth muscles than connective tissue. Vasoconstriction and vasodilation of these vessels is controlled by the autonomic nervous system.ontraction of the smooth muscles of the media is called vasoconstriction and results in a decrease in the size of the lumen and a decrease in blood flow. Relaxation of the smooth muscles is vasodilation which has the opposite effects.
