Primarily supporting Florida's tourism industry, this nickname references the great measure of sunshine that falls upon the state each year. The Alligator State This nickname grew from the number of alligators that lived in the streams and swamplands of Florida.
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.
Coordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels of the left/body/systemic and right/lungs/pulmonary circulatory systems. This complex mechanism illustrates systole of the heart.nother histological difference between cardiac muscle and skeletal muscle is that the T-tubules in the cardiac muscle are bigger and wider and track laterally to the Z-discs. There are fewer T-tubules in comparison with skeletal muscle.
