Function The arteria vertebralis supplies the brain and parts of the spinal cord with oxygen-rich blood. Especially cerebellum, brain stem and occipital lobe are supplied by the arteria vertebralis (see anatomy). An important function of the arteria vertebralis only becomes relevant in the case of a specific clinical picture. If a patient suffers from the … Function | Vertebral artery
Arteria vertebralis Dissection The dissection of an artery refers to the splitting of the inner vessel wall (intima). As a result, bleeding can occur between the intima and the media (middle vessel wall). This leads to a constriction (stenosis) or, in the worst case, to complete closure of the vessel with circulatory problems in the … Arteria vertebralis Dissection | Vertebral artery
Synonyms in a broader sense Aorta, main artery, aorta, body aorta Medical: thoracic aorta, abdominal aorta English: aorta Definition The aorta is the largest blood vessel in the body and is also called the aorta. It is divided into four sections. With a total length of about 35 – 40 cm it has a diameter … The aorta
Function of the aorta The heart pumps blood into the aorta in pulses. This pulsatile blood flow must be converted into a continuous flow to supply the body. While the aorta stretches well, especially near the heart, due to the high proportion of elastic fibres in the fine tissue when the blood is expelled from … Function of the aorta | The aorta
Histology and tissue (microscopy) Histologically there are three layers: 1. intima: The intima is the innermost layer of the aorta and consists of the endothelium and a subendothelial layer. On a basal lamina there are unicellular layers of so-called endothelial cells, which have a negative charge at the tip (apical) due to a glycocalyx (sugar … Histology and tissue (microscopy) | The aorta
What is an aortic prosthesis? Just as there are prostheses for joints or entire extremities, there are also prostheses for the aorta, which allow normal blood circulation. The vascular or tubular prosthesis, also known as a tubular prosthesis, is usually made of plastic, such as polyethylene terephthalate, and is inserted into the part of the … What is an aortic prosthesis? | The aorta
Synonyms artery, artery, pulsating artery, vein, blood vessel, vessel English: artery Introduction According to the microscopic building material predominant in the middle layer (tunica media) of the artery, two types of arteries can be distinguished Arteries of the elastic type are mainly the large arteries near the heart. These include the main artery (aorta) and … Types of arteries
Blocking arteries (Arteria convolutae) Blocking arteries can reduce the width of the vessel so much that little or no blood can flow through the vessel. This allows the blood supply to various organs to be regulated. This regulation of the artery is of particular importance in the human body for the sexual organs, as well … Blocking arteries (Arteria convolutae) | Types of arteries
femoral artery, femoral artery, femoral artery Definition The femoral artery is the main vessel for supplying the lower extremity with oxygen-rich blood. It has a diameter of about 1cm in healthy persons (deviations or differences between the sexes can occur) and gives off numerous branches in its course. Course of the leg artery The femoral … Leg artery
Constriction and occlusion of the leg artery Constrictions or blockages in the area of the aorta can occur suddenly (acute) or over a longer period of time (chronic). Behind the popularly known “shop window disease” or “smoker’s leg” is a chronic narrowing or occlusion of the aorta. This vascular disease belongs to the complex of … Constriction and occlusion of the leg artery | Leg artery
Aneurysm of the leg artery An aneurysm is a pathological vasodilatation of an artery that leads to an excessive increase in the diameter of the vessel. An aneurysm can be congenital or acquired. The most important risk factor for the development of an aneurysm is arteriosclerosis. This in turn is mainly caused by overweight, high … Aneurysm of the leg artery | Leg artery
What is the aortic root? The aortic root is a small section of our main artery (aorta). The aorta starts at the heart and then moves through the chest and abdomen via an arch where it supplies blood to various organs. The aortic root is the first section of the ascending aorta, which is only … Aortic Root
