Function Of Intercalated Discs In Cardiac Muscle

Desmosomes are other structures. Intercalated discs intercalated discs are small connections that join cardiac muscle cells cardiomyocytes to each other.

Intercalated Discs Anatomy Pictures And Information

Intercalated discs are microscopic identifying features of cardiac muscle.

Function of intercalated discs in cardiac muscle. Intercalated discs connect cardiac muscle cells. They are considered to be very important as they work as a connecting link between the two adjacent cardiac cells. Gap junctions inside the intercalated discs relay electrical impulses from one cardiac muscle cell to another.

Intercalated disc s are the major portal for cardiac cell to cell communication which is required for coordinated muscle contraction and maintenance of circulation. They occur at the z line of the sarcomere and can be visualized easily when observing a longitudinal section. The gap junctions promote diffusion of ions between cells and allow waves of depolarization to spread over the entire heart by passing from cell to cell.

These are found only in cardiac tissue. By contrast skeletal muscle consists of multinucleated muscle fibers and exhibit no intercalated discs. Their aim is to help a number of cardiac cells in contracting since when it is done the heart can function effectively so it is very much essential.

An intercalated disc forms connections between neighboring cells in the heart. These structures are highly specialized and enable the coordinated function of the heart cells known as myocytes to allow the heart to beat. Cardiac muscle fibers cells also are extensively branched and are connected to one another at their ends by intercalated discs.

Intercalated discs are known to be located inside the cardiac muscles. In human cardiovascular system. An intercalated disc allows the cardiac muscle cells to contract in a wave like pattern so that the heart can work as a pump.

Cardiac muscle consists of individual heart muscle cells connected by intercalated discs to work as a single functional organ or syncytium. Intercalated discs function purpose the primary role of the cross bands is to hold the adjacent cells together by providing sites of strong adhesion. Wall of the heart muscle cells unique junctions called intercalated discs gap junctions link the cells together and define their borders.

Intercalated discs support synchronized contraction of cardiac tissue.
