densa การใช้

• Together, the macula densa and juxtaglomerular cells comprise the juxtaglomerular complex.
• The lamina densa was formerly known as the basal lamina.
• The lamina densa is the central layer consisting of type IV collagen and laminin.
• The juxtaglomerular cells are also stimulated to release renin by signaling from the macula densa.
• The macula densa serves as the detector, while the glomerulus acts as the effector.
• Together, juxtaglomerular cells, extraglomerular mesangial cells and macula densa cells comprise the juxtaglomerular complex.
• D'Anjou and Bosc, with their densa, crisper texture hold up well when heated.
• If less Na + is sensed by the macula densa, renin release by juxtaglomerular cells is increased.
• This demonstrates the macula densa feedback, where compensatory mechanisms act in order to return GFR to normal.
• When there is a decrease in the sodium concentration, less sodium is reabsorbed in the macular densa cells.
• The point where DCT contacts the cortical thick ascending limb of the loop of Henle is called macula densa.
• The basal lamina is composed of 3 layers : lamina rara externa, lamina densa, and lamina rara interna.
• Among the multiple thick forms of hot chocolate served in Europe is the Italian " cioccolata densa ".
• However, unlike the lamina densa, the electron-dense zone adjacent to enamel show no signs of hemidesmosomes.
• The macula densa cell can also increase the blood pressure of the afferent arterioles by decreasing the synthesis of adenosine or ATP.
• Hence, a decrease in blood pressure results in less NaCl present at the distal tubule, where the macula densa is located.
• "Aspidotis densa " develops on crevices and exposed rocky outcrops in mossy cracks, overtime creeps to fill in every fissure.
• Oxygenating plants include anacharis ( Elodea densa ), parrot's feather ( Myriophyllum brasilienese ) and red hygrophilia ( Hygrophilia polysperma rubra ).
• Beta blockade, especially of the beta-1 receptor at the macula densa, inhibits renin release, thus decreasing the release of aldosterone.
• The macula densa does not regulate the dilation of the efferent arterioles and afferent arterioles do not dilate in response to increases in filtrate osmolarity.
