The nutrient artery (arteria nutricia, or central artery), usually accompanied by one or two nutrient veins, enters the bone through the nutrient foramen, runs obliquely through the cortex, sends branches upward and downward to the bone marrow, which ramify in the endosteum–the vascular membrane lining the medullary cavity–and give twigs to the adjoining canals.
The nutrient canal (foramen) is directed away from the growing end of bone. The growing ends of bones in upper limb are upper end of humerus and lower ends of radius and ulna. In lower limb, the lower end of femur and upper end of tibia are the growing ends. [1] The nutrient arteries along with nutrient veins pass through this
It supplies a perforating branch to both the lateral and anterior compartments of the leg; it also provides a nutrient artery to the fibula. Some sources claim that the fibular artery arises directly from the posterior tibial artery, but vascular and plastic surgeons note the clinical significance of the tibial-fibular trunk. [2]
Oxygen (bound to hemoglobin in red blood cells) is the most critical nutrient carried by the blood. In all arteries apart from the pulmonary artery, hemoglobin is highly saturated (95–100%) with oxygen. In all veins, apart from the pulmonary vein, the saturation of hemoglobin is about 75%.
The third perforating artery (a. perforans tertia) is given off below the Adductor brevis; it pierces the Adductor magnus, and divides into branches which supply the posterior femoral muscles; anastomosing above with the higher perforating arteries, and below with the terminal branches of the profunda and the muscular branches of the popliteal.
Coronary Artery Disease. Coronary artery disease, or coronary heart disease, is the most common type of heart disease. It occurs when fatty deposits called plaques build up in your arteries ...
Most vessels of the microcirculation are lined by flattened cells of the endothelium and many of them are surrounded by contractile cells called pericytes.The endothelium provides a smooth surface for the flow of blood and regulates the movement of water and dissolved materials in the interstitial plasma between the blood and the tissues.
For example, if you have an office in San Francisco, Los Angeles, New York, or another big city and it’s 100% office, you're going to have to pay higher wages and limit the number of people who ...
