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.
The intercalated discs also act as points of anchorage for the contractile proteins, and they contain important channels called GAP JUNCTIONS. These connect the cytoplasm of adjacent cardiac muscle fibres and permit the extremely rapid low-resistance spread of action potentials from one cell to another.itochondria are more numerous in cardiac muscle cells than in skeletal muscle, and the T-Tubules are continuous with the cell membrane. These carry action potentials into the cell interior and are well developed in the ventricles of the heart, but poorly developed in both atria.
