Esempi di utilizzo di ARTERIOLE in una frase

• Manifestations of these changes include Copper wire arterioles where the central light reflex occupies most of the width of the arteriole and Silver wire arterioles where the central light reflex occupies all of the width of the arteriole, and "arterio-venular (AV) nicking" or "AV nipping", due to venous constriction and banking.
• It is found between afferent arteriole and the thick ascending limb of the loop of Henle (distal straight tubule) of the same nephron.
• An arteriole is a small-diameter blood vessel in the microcirculation that extends and branches out from an artery and leads to capillaries.
• Histologically, glomus tumors are made up of an afferent arteriole, anastomotic vessel, and collecting venule.
• The pathogenesis of renovascular hypertension involves the narrowing of the arteries supplying the kidneys which causes a low perfusion pressure that is detected by the juxtaglomerular apparatus (via the macula densa cells, which act as baroreceptors; located on the afferent arteriole wall).
• As with the arteriole distribution, the veins follow the same pattern: the interlobular provide blood to the arcuate veins then back to the interlobar veins, which come to form the renal vein exiting the kidney for transfusion for blood.
• In the renal system, peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole, that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron.
• For cortical nephrons, a single network of capillaries, known as the peritubular capillaries, surrounds the entire renal tubule, whereas for juxtamedullary nephrons, the peritubular capillaries surround only the proximal and distal convoluted tubules, while another network branching from the efferent arteriole, known as the straight arterioles of kidney, surrounds the nephron loop (of Henle).
• Extraglomerular mesangial cells are part of the juxtaglomerular apparatus, along with the macula densa cells of the distal convoluted tubule and the juxtaglomerular cells of the afferent arteriole.
• Abundant cotton wool spots are also found in hypertensive retinopathy, including malignant hypertension, where the white patches are a result of a microvascular infarct, or a sudden occlusion of the arteriole.
• Arteriovenous nicking, also known as AV nicking, is the phenomenon where, on examination of the eye, a small artery (arteriole) is seen crossing a small vein (venule), which results in the compression of the vein with bulging on either side of the crossing.
• This is seen at right-angle crossing points, where the venule crosses the arteriole in a horseshoe shape.
