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.
cardiac muscle cells also have intercalated discs that allow for rapid propagation of impulses. skeletal muscles contract much faster than cardiac muscle cells and also have a shorter refractory period. as a result of a longer refractory period, cardiac muscle cells cannot show wave summation and tetany.ardiac muscle cells also have intercalated discs that allow for rapid propagation of impulses. skeletal muscles contract much faster than cardiac muscle cells and also have a shorter refractory period. as a result of a longer refractory period, cardiac muscle cells cannot show wave summation and tetany.
