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.
Intercalated discs Definition. These are transverse bands that separate the adjacent ends in cardiac muscle fibers. Normally these structures appear as stained irregular lines at 90 degrees to the striped sarcomeric pattern.ntercalated discs Description. The cross-bands contain the following components that act as cell-cell junctions: 1  Fascia adherens: These are majorly the anchoring regions for actin. 2  Once attached, the thin filaments of actin bind to the sarcomeres of the cardiac muscles.
