	Glomerulus (olfaction) - Wikipedia, the free encyclopedia
		The glomerulus (plural glomeruli) in olfaction is a structure in the olfactory bulb.
		It is made up of a globular tangle of axons from the olfactory receptor neurons in the olfactory epithelium and dendrites from the mitral cells, tufted cells, and other cell types.
		The glomerulus is the basic unit in the odor map of the olfactory bulb.

	Urinary System Information (Site not responding. Last check: 2007-10-21)
		Filtration of the blood occurs in the renal corpuscle between the Bowman's capsule and glomerulus.
		In this nonselective process, fluid and tiny particles in the glomerulus pass from the blood into the Bowman's capsule and renal tubules.
		The path from the renal artery to the glomerulus runs as follows: lobar artery, interlobar artery, arcuate artery, interlobular artery, and afferent arterioles.

		It is invaginated by a tuft of capillaries at the vascular pole of the glomerulus.
		You should be able to identify the vascular pole of a good glomerulus by the attachment of the capillary tuft to the wall of the glomerulus.
		At the point of contact with the glomerulus, the distal tubule is always in close contact with the endothelial cells of the efferent and afferent arterioles of the glomerulus.

		A given glomerulus thus reflects the molecular receptive range of the receptor expressed by the population of sensory neurons that projects to it.
		An advantage of the insect for this kind of study lies in stimulus control; puffs of different durations, concentrations and repetition rates can be controlled precisely, simulating the way a moth normally follows an odor plume, which is to sense changes in the frequency of the intermittent odor plumes emitted.
		The similarity of the bursts extends to the timing of the individual impulses, which is key, because it means that the synchronous impulses sum to amplify the strengths of the individual responses.

	Glomerulus definition - Medical Dictionary definitions of popular medical terms
		In the kidney, a tiny ball-shaped structure composed of capillary blood vessels actively involved in the filtration of the blood to form urine.
		The glomerulus is one of the key structures that make up the nephron, the functional unit of the kidney.
		"Glomerulus" is the diminutive of the Latin "glomus" meaning "ball of yarn." It is literally a "little ball of yarn." Plural: glomeruli.

	Renal Physiology (Site not responding. Last check: 2007-10-21)
		A renal tubule extends from Bowman's capsule to the collecting tubule and is sectioned into: the Proximal convoluted tubule, the Loop of Henle (with descending and ascending limbs) and the Distal convoluted tubule, which connects with the collecting tubules (which run down through medulla of the kidney and join the calyces).
		Circulation: renal artery to afferent arterioles to glomerulus to efferent arterioles to peritubular capillaries
		There is a 20 mm Hg pressure gradient, between the pressure in the glomerulus and Bowman's capsule, which causes fluid to flow out of the blood (in the glomerulus) and into Bowman's capsule.

	Searle Scholar Profile : Jing Wang (2005)
		Each receptor neuron expresses just one receptor gene and neurons expressing the same receptor gene converge with high accuracy onto a single glomerulus in the olfactory bulb, establishing the notion that the olfactory system employs spatial segregation of sensory input to encode the quality of odors.
		By comparing odor responses of sensory neuron axons and dendrites of projection neurons (PNs) in the same glomerulus with the expression of G-CaMP in only one cell type, we found similar odor-evoked activity in both pre- and postsynaptic cells, which suggests that activity in PNs derives mainly from their cognate sensory neurons.
		By expressing G-CaMP in all neurons, we identified the V glomerulus as the only region in the antennal lobe that shows response to CO, which elicits innate avoidance behavior in the T-maze paradigm.

		The central filtration device is the "glomerulus." While the glomerulus is the central part of the filtration apparatus, it is really not the only part.
		Bowman's capsule forms a tight seal around the glomerulus such that all of the fluid being filtered out of the glomerulus is caught in the capsular space.
		The glomerulus is a high pressure capillary network and is the renal structure responsible for filtration of plasma.

		A comprehensive view of the physiological antioxidant- oxidant balance in the glomerulus and proximal tubule would aid in the understanding of oxygen radical-induced injury in glomerular and tubulo-interstitial disease.
		The relevance of the observed differences to pathophysiological states remains to be determined, but a greater susceptibility of the glomerulus to oxidant stress and tissue damage might be anticipated.

		Researchers believe such particles could carry therapeutic genes to the glomerulus, a tiny cluster of capillaries within the kidney that filters toxins from the blood.
		Previous work by these researchers showed that a 16-micrometer particle is the right size to lodge in the glomerulus of a rat.
		While the architecture of the glomerulus allows the filter to withstand some degree of blood vessel blockage – it is a mass of interconnected capillaries – other organs, such as the heart, don’t have the same sort of network.

	Local inhibition modulates odor-evoked synchronization of glomerulus-specific output neurons - Nature Neuroscience (Site not responding. Last check: 2007-10-21)
		PNs that branched in the same glomerulus and were activated by the same pheromone component also showed the strongest coincident responses to each odor pulse.
		Glomerulus-specific PN pairs were also inhibited by the pheromone component that selectively activated PNs in the neighboring glomerulus, and about 70% of all intraglomerular pairs showed increased synchronization when stimulated with a mixture of the two odorants.
		Thus, when two adjacent glomeruli receive their inputs simultaneously, the temporal tuning of output from each glomerulus is enhanced by reciprocal and inhibitory interglomerular interactions.

	Bio 336 Practice Final Exam
		The efferent arteriole that exits the glomerulus of the nephron gives rise to a second capillary network called the 1 that weaves around the proximal convoluted tubule, loop of Henle, and the distal convoluted tubule.
		Inside the capillary walls of the glomeruli (plural of glomerulus), there is a net pressure gradient of 20 hydrostatic (blood) pressure forcing fluid through the capillary walls; this is called the 3 and it is uniform over the entire length of the glomerular capillary network.
		The blood leaving the glomerulus (not filtered) goes through the efferent arteriole and enters the 13.

		Since the glomerulus works by filtration it's not surprising that it has a relatively high blood pressure for a capillary.
		Because the simple squamous of the glomerulus has holes, the only real barrier to fluid flow is the basement membrane found between the cells of the glomerulus and the cells of the capsule.
		The blood pressure in the glomerulus is higher than osmotic pressure in the capsule and the backpressure of the filtrate.

	Ole Sonne: Nyrefysiologi
		Blod tilføres det enkelte nefron (tegningen) gennem den afferente arteriole, løber gennem glomerulus (et hårkarsnøgle) og ud gennem den efferente arteriole.
		En medvirkende årsag til denne proces er det øgede kolloidosmotiske tryk i plasma i de peritubulære kapillærer, som blev skabt ved ultrafiltratdannelsen i glomerulus.
		Derfor vil der være en glomerulotubulær balance: jo mere, der udfilreres, des højere kolloidosmotisk tryk i det plasma, som forlader glomerulus og går til de peritubulære kapillærer, og dermed des større "sugeevne" i papilinterstitset, og dermed jo mere væske kan fjernes og gøre plads til noget nyt, som reabsorberes.

	Hypertension Online Slides - glomerulus, macrophage, glomerular hypertension
		The nephron, comprised of the glomerulus (shown in the scanning electron photomicrograph on the top left and in the center of the light micrograph on the bottom left) and the tubules (surrounding the glomerulus in the light micrograph on the bottom left), is the primary functional unit of the kidney.
		Both glomerular hypertension and proteinuria are associated with oxidative stress that can cause activation of circulating leukocytes and their diapedesis into the vessel wall and interstitium, can stimulate the release of cytokines and growth factors that leads to extracellular matrix formation, progressive sclerosis of both the glomerulus and tubules, and ultimately loss of nephron units.
		Attempts by the proximal tubules to reabsorb this filtered protein causes injury to the tubular cells, activates an inflammatory response, and is associated with the development of lipid metabolic abnormalities that create further oxidative stress on the already compromised glomerulus.
