osmo-, osmia-, osmi-, -osmia, -osmatic (push) +
(Greek: impulse, thrust, push, impel)
Don't confuse this osmo- word-unit with another osmo- unit meaning "smell, odor".
hypo-osmosis, hyposmosis
Decreased speed of osmosis.
hypo-osmotic, hyposmotic
1. Containing a lower concentration of osmotically active components than a standard solution.
2. Having an osmolality less than another fluid, ordinarily assumed to be plasma or extracellular fluid
2. Having an osmolality less than another fluid, ordinarily assumed to be plasma or extracellular fluid
osmium (chemical element)
Information is located at Chemical Element: osmium .
osmium
1. A very hard, gray, toxic, and nearly infusible metal.
2. A homeopathic trituration (reduction of solid bodies to a powder by continuous rubbing) of metallic osmium.
2. A homeopathic trituration (reduction of solid bodies to a powder by continuous rubbing) of metallic osmium.
Osmium tetroxide (OsO4), a colorless or light yellow crystalline compound with a pungent odor, used as a fixative in preparing histologic specimens; if splashed in the eyes it can cause conjunctivitis, corneal damage, and in severe cases blindness. Also called, osmic acid.
Used chiefly as a catalyst, in alloys, and in the manufacture of electric-light filaments.
osmoconformer
A cell having an internal osmotic pressure that varies with the osmotic pressure of its environment.
osmol (s), osmols (pl)
The quantity of a solute, existing in solution as molecules and/or ions, commonly stated in grams, which is osmotically equivalent to one mole of an ideally behaving nonelectrolyte.
osmolality
Osmotic pressure expressed in terms of osmols or milliosmols per kilogram of water.
osmolar
Of or pertaining to the osmotic property of a solution containing one or more molecular or ionic species, quantitatively expressed in osmol units.
osmolarity
Osmotic pressure expressed in terms of osmols or milliosmols per kilogram of solution.
osmology
That part of physical science dealing with osmosis.
osmometer
1. An apparatus for measuring osmotic pressure.
2. An instrument used to determine the osmolal concentration of a solution.
2. An instrument used to determine the osmolal concentration of a solution.
osmometry
A process of measuring molecular weights based on the osmotic pressure derived when molecules diffuse through a semipermeable membrane.
An organism that thrives in a medium of high osmotic concentration: An osmophile is a microorganism that is similar to a halophile, or salt-loving form of life, because they both share a common environment of low water activity.
osmophilic (adjective), more osmophilic, most osmophilic
Concerning an affinity for solutions of high osmotic pressure: Osmophilic forms of life have an attraction to osmium, and therefore have a black appearance under the light microscope.
osmoreceptors
Structures in the hypothalamus which respond to changes in osmotic pressure of the blood by regulating the secretion of the neurohypophyseal antidiuretic hormone.
