It is a brown amorphous substance. Source: Websters Dictionary (01 Mar 1998) |

| osmium | <chemistry> A rare metallic element of the platinum group, found native as an alloy in platinum ore, and in iridosmine. It is a hard, infusible, bluish or grayish white metal, and the heaviest substance known. Its tetroxide is used in histological experiments to stain tissues. Symbol Os. Atomic weight 191.1. Specific gravity 22.477. Origin: Gr. A smell, odour, akin to to smell. So named in allusion to the strong chlorinelike odour of osmic tetroxide. See Odour. Source: Websters Dictionary (01 Mar 1998) |
| osmium compounds | Inorganic compounds that contain osmium as an integral part of the molecule. (12 Dec 1998) |
| osmium tetroxide | <chemical> Used as a post fixative/stain in electron microscopy. Membranes in particular are osmiophilic, i.e. Bind osmium tetroxide. (18 Nov 1997) |
| osmo- | 1. Osmosis. Origin: G. Osmos, impulsion 2. Smell, odour. Origin: G. Osme (05 Mar 2000) |
| osmoceptor | 1. A receptor in the central nervous system (probably the hypothalamus) that responds to changes in the osmotic pressure of the blood. Origin: G. Osmos, impulsion 2. A receptor that receives olfactory stimuli. Origin: G. Osme, smell Synonym: osmoceptor. (05 Mar 2000) |
| osmodysphoria | An abnormal dislike of certain odours. Origin: G. Osme, smell, + dys-, bad, + phora, a carrying (05 Mar 2000) |

| osmolal clearance | The volume of urine that would be excreted per minute if the urinary solutes were accompanied by just enough water to make the urine isosmotic with plasma, i.e., so that the solute excretion did not change the osmolality of body fluids. To calculate it, the volume of urine excreted per minute is multiplied by the urinary osmolality (usually measured by freezing point depression) and divided by the plasma osmolality. Osmolal clearance is less than actual urine flow when urine is hyposmotic and exceeds it when urine is hyperosmotic. (05 Mar 2000) |
| osmolality | <chemistry> The concentration of osmotically active particles in solution expressed in terms of osmoles of solute per kilogram of solvent. The osmolality is directly proportional to the colligative properties of solutions, osmotic pressure, boiling point elevation, freezing point depression and vapour pressure lowering. (18 Nov 1997) |
| osmolar | <chemistry> Pertaining to or of the nature of osmosis (= the passage of pure solvent from a solution of lesser to one of greater solute concentration when the two solutions are separated by a membrane which selectively prevents the passage of solute molecules, but is permeable to the solvent). (18 Nov 1997) |
| osmolar concentration | The concentration of osmotically active particles in solution expressed in terms of osmoles of solute per liter of solution. Osmolality is expressed in terms of osmoles of solute per kilogram of solvent. (12 Dec 1998) |

| osmium |
Osmium is a chemical element in the periodic table that has the symbol Os and atomic number 76. A hard brittle blue-gray or blue-black transition metal in the platinum family, osmium is the densest natural element and is used in some alloys with platinum and iridium. Osmium is found native as an alloy in platinum ore and its tetroxide has been used to stain tissues and in fingerprinting. ...

| osmoregulation |
Osmoregulation is the active regulation of the osmotic pressure of bodily fluids to maintain the homeostasis of the body's water content; that is it keeps the body's fluids from becoming too dilute or too concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis. The higher the osmotic pressure of a solution the more water wants to go into the solution. ...
