Collecting Duct Cells ( CD) Principal cells are the main Na+ reabsorbing cells and the site of action of aldosterone, K+-sparing diuretics, and spironolactone. Type A and B intercalated cells make up the second cell type in the collecting duct epithelium. Type A intercalated cells mediate acid secretion and bicarbonate reabsorption.he collecting duct cells (CDCs) are highly water permeable and are a key component of the collecting duct, the last site where NaCl and water are reabsorbed in the kidney.

How can I keep hot food hot when transporting it? A good cooler does very well to insulate food and keep it warm. When I make pulled pork, I wrap the pork butts in foil, then towels, and keep them in a cooler. Upwards of four hours later, the butts are still hot, not just warm.irst things first, to keep the food hot you need to take into account two factors: thermal mass and heat conduction. Thermal mass is how much heat your food or its pot can retain.

Parathyroid chief cell Parathyroid chief cells are one of the two cell types of the parathyroid glands, along with oxyphil cells. The chief cells are much more prevalent in the parathyroid gland than the oxyphil cells. It is perceived that oxyphil cells may be derived from chief cells at puberty, as they are not present at birth like chief cells. Chief cells appear as a dark purple in an H&E stain, with the oxyphil cells staining as a lighter pink. They are polygonal in shape with a round nucleus.

Nephron Histology 1 Thin Loop of Henle. 2  Both the descending and ascending arms of the thin loop of Henle are histologically similar and are composed of a simple squamous epithelium. 3  These cells are not very metabolically active, consistent with the fact that they do not participate in any active transport of water or solutes. The end of the distal tubule continues into the collecting tubule that in turn merges with several other collecting tubules, thus forming a collecting duct. 2  The late distal tubule, collecting tubule, and collecting ducts form a unified functional segment referred to as the  Distal Tubule and Collecting Duct.

Juxtaglomerular apparatus The juxtaglomerular apparatus consists of three cell types. These are: 1  the macula densa, a part of the distal convoluted tubule of the same nephron. 2  juxtaglomerular cells, which secrete renin, specialized smooth muscle cells of the afferent arteriole, which supplies blood to the glomerulus.3  extraglomerular mesangial cells.t the point where the afferent arterioles enter the glomerulus and the efferent arteriole leaves it, the tubule of nephron touches the arterioles of the glomerulus from which it rose. At this location, which marks the start of distal convolution, there is a modified region of tubular epithelium called the Macula densa.

- In order to move this cerebrospinal fluid around the brain and spinal cord, ependymal cells also have little hairs, called cilia, that wave back and forth in the cerebrospinal fluid in order to help circulate it along. Microglia. The other type of glial cell found in your central nervous system is known as microglia.

- Mesonephros: 1  formed by corpuscles & tubules that develop caudal to pronephric region; form connections with existing pronephric duct (which is now called the mesonephric duct). 2  the embryonic kidney in reptiles, birds, & mammals. 3  the functional adult kidney in fish & amphibians (& sometimes called the opisthonephros). Glomeruli are masses of capillaries that (along with Bowman's capsule) 'filter' the blood-the first step in eliminating waste products from the blood. 2  Kidney tubules collect the glomerular filtrate & conduct it to a longitudinal duct.

What are the different types of cells in the kidney? The major cell of the distal tubule is a cell that contains the so-called thiazide-sensitive sodium chloride cotransporter (TSC). This cell is responsible for reabsorbing about 5% of the sodium filtered by the kidney each day. It is targeted by another type of drug (called thiazides) that treats high blood pressure.ike in other organs, cells of the kidney can be divided into cells that make up the functional part of the kidney (called the parenchyma) and cells that make up the connective tissue and supporting structure of the kidney (the stroma).

- The two general classes of nephrons are cortical nephrons and juxtamedullary nephrons, both of which are classified according to the length of their associated Loop of Henle and location of their renal corpuscle.he majority of nephrons are cortical. Cortical nephrons have a shorter loop of Henle compared to juxtamedullary nephrons. The longer loop of Henle in juxtamedullary nephrons create a hyperosmolar gradient that allows for the creation of concentrated urine.

Schwann cell Glial cells function to support neurons and in the PNS, also include satellite cells, olfactory ensheathing cells, enteric glia and glia that reside at sensory nerve endings, such as the Pacinian corpuscle. There are two types of Schwann cell, myelinating and nonmyelinating.n this sense, Schwann cells are the peripheral nervous system's analogues of the central nervous system 's oligodendrocytes. However, unlike oligodendrocytes, each myelinating Schwann cell provides insulation to only one axon (see image).

What are the different types of cells in the kidney? The collecting duct contains two cell types, called principal cells and intercalated cells. Principal cells are predominantly responsible for sodium reabsorption and potassium secretion in the kidney. This process is stimulated in the principal cells by the action of the hormone aldosterone.ike in other organs, cells of the kidney can be divided into cells that make up the functional part of the kidney (called the parenchyma) and cells that make up the connective tissue and supporting structure of the kidney (the stroma).

Kidney The proximal tubule then changes to squamous epithelium which passes down to the medulla and then loops back up to the cortex. There are highways of tubules called MEDULLARY RAYS that contain tubules passing to the medulla. The thin part of the nephron is called the LOOP of HENLE.ove into the medulla and find the tubules there. You should be able to distinguish the VASA RECTA by their content of blood cells. Also, the thin limbs and the thicker limbs of the LOOP of HENLE can be seen. Finally, the COLLECTING TUBULES are cuboidal and columnar.

Chapter 11 - The Cerebral Cortex There are several identifiable cell types in the cerebral cortex. The pyramidal cells are the main cell type within layers III and V. These cells can be extremely large in layer V of the motor cortex, giving rise to most corticobulbar and corticospinal fibers.The largest of these neurons are called Betz cells.eneral Organization. The cerebral cortex is the outer covering of gray matter over the hemispheres. This is typically 2- 3 mm thick, covering the gyri and sulci. Certain cortical regions have somewhat simpler functions, termed the primary cortices.
