Synonyms Cardia, pericardium, epicardium, myocardium, endocardium Medical: Cor Pericardium Epicardium Myocardium Endocardium. The next and by far the thickest layer is the heart muscle (myocardium). It is the actual motor of the cardiovascular system. The muscles are separated from the blood only by a very thin layer of cells (endocardium), which is very smooth on … Heart
HistologyTissue The endocardium is a flat, unicellular layer that separates the chamber muscles from the blood. It corresponds functionally to the inner lining of the blood vessels (endothelium). Its function, preventing the formation of a blood clot (thrombus), is ensured by its special smooth surface and by the production of anticoagulants (nitrogen monoxide (NO), prostacyclin). … HistologyTissue | Heart
The bacterium Streptococcus mitis belongs to the viridans streptococci. Viridans streptococci are found predominantly in the mouth and throat. What is streptococcus mitis? Mitis bacteria are gram-positive and belong to the streptococcus bacterial genus. Streptococci are spherical bacteria that prefer to be arranged in chains. Gram-positive bacteria can be stained blue in the Gram stain. … Streptococcus Mitis: Infection, Transmission & Diseases
Papillary muscles are small conical, inwardly directed, muscle elevations of the ventricular muscles. They are connected by branching chordae to the edges of the leaflet valves, which act as passive check valves to regulate blood flow from the left atrium to the left and right ventricles. Immediately before the contraction phase of the ventricles, the … Papillary Muscle: Structure, Function & Diseases
The heart consists of different layers. The innermost layer is the endocardium. As the innermost layer, it comes into direct contact with the blood that flows through the heart. The endocardium (from inside to outside) contains the myocardium (the layer of the heart muscle) and the epicardium (the outer skin of the heart). The pericardium, … Endocardium
Diseases The inflammation of the inner skin of the heart is called endocarditis. Untreated, this disease is usually fatal, but nowadays it is easily treatable with antibiotics. Other diseases are Löffler’s endocarditis and endomyocardial fibrosis. Diagnostics Echocardiography is used to visualize the endocardium. This allows the heart valves in particular to be examined very well. … Diseases | Endocardium
Streptococcus sanguis are bacteria of the genus Streptococcus, which belong to the group of viridans streptococci and are a natural component of the human oral flora. The bacteria prevent the oral flora from being colonized by pathogenic bacteria and thus prevent caries, for example. If carried into the blood, however, the bacteria can cause inflammation … Streptococcus Sanguis: Infection, Transmission & Diseases
Anatomy The AV node, like the sinus node, is located in the right atrium. However, it lies further down, more precisely at the transition to the right ventricle and thus in Koch’s triangle. Just like the sinus node, the AV node does not consist of nerve cells, but of specialized heart muscle cells that have … AV node
