Hyperplasia is considered to be a physiological (normal) response to a specific stimulus, and the cells of a hyperplastic growth remain subject to normal regulatory control mechanisms. [5] However, hyperplasia can also occur as a pathological response, if an excess of hormone or growth factor is responsible for the stimuli.
A body of frozen water more than 50,000 km 2: Inlet: a body of water, usually seawater, which has characteristics of one or more of the following: bay, cove, estuary, firth, fjord, geo, sea loch, or sound. Kettle (or kettle lake) a shallow, sediment-filled body of water formed by retreating glaciers or draining floodwaters. Kill
The cause is usually pressure from the flange of a denture which causes chronic irritation and a hyperplastic response in the soft tissues. [6] Women during pregnancy can also present with an epulis, which will resolve after birth. Fibroepithelial polyps, pedunculated lesions of the palate beneath an upper denture, are associated with this ...
The Black Sea is an example of a body of water with a prominent chemocline, though similar bodies (classified as meromictic lakes) exist across the globe. [ 4 ] [ 5 ] Meromictic lakes are the result of meromixis, which is a circumstance where a body of water does not fully mix and circulate, causing stratification .
The resulting body of polluted water within an aquifer is called a plume, with its migrating edges called plume fronts. Plumes are used to locate, map, and measure water pollution within the aquifer's total body of water, and plume fronts to determine directions and speed of the contamination's spreading in it.
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
In oceanography, a halocline (from Greek hals, halos 'salt' and klinein 'to slope') is a cline, a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water. [1] Because salinity (in concert with temperature ) affects the density of seawater , it can play a role in its vertical stratification .
An open lake is a lake where water constantly flows out under almost all climatic circumstances. Because water does not remain in an open lake for any length of time, dissolved solids do not accumulate, and such lakes are usually fresh water. Open lakes form in areas where precipitation is greater than evaporation. Because most of the world's ...
