Hypertensive kidney disease this situation, the kidney supplied blood by the narrowed renal artery suffers from inadequate blood flow, which in turn causes the size of the kidneys to decrease. Other consequences include arterial stiffening, which involves a gradual breakdown of elastic fibers and intima (the innermost layer of a blood vessel) thickening. An alternative mechanism of hypertensive nephropathy is prolonged glomerular hypertension and hence glomerular hyperfiltration. These can occur simultaneously but not necessarily. The idea is that hypertension results in sclerosis of the glomeruli which ultimately means reduced kidney function. As a compensatory mechanism, the unaffected nephrons (specifically, the preglomerular arterioles) vasodilate
Ascending palatine artery upper border of the superior pharyngeal constrictor, supplies the soft palate and the palatine glands, anastomosing with its fellow of the opposite side and with the descending palatine branch of the maxillary artery; the other pierces the superior pharyngeal constrictor and supplies the palatine tonsil and auditory tube, anastomosing with the tonsillar branch of the facial artery and the ascending pharyngeal artery. Ascending palatine artery The ascending palatine artery is an artery in the head that branches off the facial artery and runs up the superior pharyngeal constrictor muscle. The ascending palatine artery arises close to the origin of the
