Thirst
Definition:
(n.) A sensation of dryness in the throat associated with a craving for liquids, produced by deprivation of drink, or by some other cause (as fear, excitement, etc.) which arrests the secretion of the pharyngeal mucous membrane; hence, the condition producing this sensation.
(n.) Fig.: A want and eager desire after anything; a craving or longing; -- usually with for, of, or after; as, the thirst for gold.
(n.) To feel thirst; to experience a painful or uneasy sensation of the throat or fauces, as for want of drink.
(n.) To have a vehement desire.
(v. t.) To have a thirst for.
Example Sentences:

(2) The results suggest that angiotensin and cholinergic receptors in the brain have a physiological role in thirst.
(3) Experiments in which this method has been applied to the measurement of hunger and thirst in doves are outlined, and the results are discussed in terms of their implications for motivation theory in general.
(4) The subjects described the thirst sensations as mainly due to a dry unpleasant tasting mouth, which was promptly relieved by drinking.
(5) To determine whether centrally released vasopressin influences thirst, observations of osmotic thirst threshold, osmotic load excretion and postloading restitution of plasma osmolality were made in dogs in control experiments and during infusion of AVP antagonists into the third ventricle.
(6) The results of these studies, considered as a whole, support the view that McCleary's osmotic postingestional satiety signal acts as an intestinal distention signal rather than by inducing thirst.
(7) These findings suggest the following sequence of events: impaired A-II production caused impairment of thirst perception, renal-concentrating capacity, and AVP secretion and contributed to development of hypernatremic dehydration in these elderly patients.
(8) We postulated that the high salt content of CF patients' sweat and the consequent absence of body-fluid hyperosmolality during a long episode of sweating might deprive such patients of a thirst stimulus.
(9) The fall in plasma osmolality associated with human pregnancy is accounted for entirely by a lowering of the osmotic thresholds for thirst and vasopressin release.
(10) To investigate further the stimulus for this effect, its specificity, and association with thirst, six volunteers were deprived of water for 24 h and given a salt load on two separate occasions.
(11) Beliefs best differentiating among the three groups were: (1) superiority of taste of their "own" sodas, (2) perceived efficiency to quench thirst, and (3) perceived compatibility with other menu items.
