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
Medial plantar artery of the first three spaces. A superficial branch which supplies a plantar digital artery to the medial side of the 1st toe, and a deep branch which assists in supplying blood to the plantar metatarsal arteries. Medial plantar artery The medial plantar artery (internal plantar artery), much smaller than the lateral plantar artery, passes forward along the medial side of the foot. It is at first situated above the abductor hallucis, and then between it and the flexor digitorum brevis, both of which it supplies. At the base of the first metatarsal bone, where it is much diminished in size,
