  • Porcine
  • We have recently documented the constitutive expression of arginase-I in porcine coronary arterioles and demonstrated its functional role in modulating coronary microvascular tone under physiological 12 and pathophysiological conditions. (ahajournals.org)
  • endothelial
  • Cyclooxygenase inhibition improves endothelial vasomotor dysfunction of visceral adipose arterioles in human obesity. (nih.gov)
  • Our findings suggest that cyclooxygenase-mediated vasoconstrictor prostanoids partly contribute to endothelial dysfunction of visceral adipose arterioles in human obesity. (nih.gov)
  • Coloured transmission electron micrograph (TEM) of a section through the wall of an arteriole, showing smooth muscle (brown), endothelial cells (green), and an inner and outer lamina (membrane, blue). (sciencephoto.com)
  • diameter
  • Arterioles are the smallests vessels of the arterial system, with a diameter of about 1/3 millimeter or smaller. (washington.edu)
  • Saunders and Knisely (63) found unagglutinated blood flowing at physiologic rates through terminal arterioles as narrow as, depending upon species, from 5 to 7.7 micra in diameter. (ebscohost.com)
  • Cells
  • Constricting the smooth muscle cells in the afferent arteriole, results in a reduced concentration of chloride at the MD. TGF can stabilizes the fluid and solute delivery into the distal portion of the loop of Henle and maintain the rate of filtration near its ideal value using these mechanisms. (wikipedia.org)
  • smaller
  • These arterioles get progressively smaller the more distanced they are from the heart , as most of the blood supply is required by the major organs positioned close to the heart and is provided by the [[arteries. (biology-online.org)
  • Simply
  • Simply put, the arterioles in people with FM are remaining too dilated, which the researchers say is causing the nerves to become overly sensitive. (prohealth.com)
