Tissue Muscle Heart

Cardiac muscular tissue Abstract Cardiac muscular tissue is a wide layer of fascia, which is a continuation of the skeletal muscles to the ventricles of the heart. It is made of strong, smooth, fine fibers and often thickens over time, helping to maintain normal heart rhythm and reduce stress.

*Muscular cardiac tissue * or (t. muscularis striatus cardiaca) is a narrow layer of the endocardial fascia of the heart, which is located between the outer layer of the heart muscles (myocardium) and the fibrous membrane of the heart (epicardium). It serves to attach the heart to the sternum and rib cage, ensuring its stability and protection from external influences.

The muscle fibers in this area have a special structure, which makes them stronger and more elastic. That is why cardiac muscle tissue is an important element for the proper functioning of the heart and maintaining its normal rhythm. In addition, this layer of tissue helps reduce stress overload that occurs during physical activity. In general, cardiac muscle tissue performs an important function in the human body, so damage or disease can lead to serious consequences.

**T. musculis str. cardiaca** has the same fibril structure of the smooth muscle wall, only the smooth muscle cells are larger and more elastic, i.e. they do not react so strongly to activators of the autonomic nervous system. T. The cardiac muscle significantly increases its thickness during adolescence and is the main reason for the reverse development of the heart (its flattening). Outside the heart, the fibers end in terminal plates (facies terminalis), forming coelomic and other types of muscularis propria. The fibrous membrane, which is located in the thickness of the abdominal organs between the layers of the muscular layer, is called subfascia or fascia of the lesser omentum (f. epiplicae pancreaticae) or bru

The tissues of the heart and abdominal cavity are covered with fibrous tissue known as the aponeurosis. Beneath this tissue is muscle tissue known as cardiac muscle tissue.

The heart muscle is made up of several types of tissues that together ensure normal heart function. These tissues include a framework of collagen fibers,
