Biology  Ectopic  Effector cell

Ectotherm: A coldblooded animal, one having a body temperature determined primarily by the temperature of its surrounding environment. Terrestrial reptiles are ectotherms.

y - This refers to creatures that control body temperature through external means (Greek: "ectos"εκ"ος = "outside," "thermos" θερμος = "warm"), such as the sun, or flowing air/water. For more on this, see below.

ectotherms Animals with a variable body temperature that is determined by the environment. Examples: fish, frogs, and reptiles.


[Gk. ecto, outside + therme, heat]
An animal such as a reptile, fish, or amphibian, that must use environmental energy and behavioral adaptations to regulate its body temperature.
effector cell ...

ectotherm /EHK-toe-therm/ An animal that uses environmental temperatures and behavior to regulate its temperature (commonly termed "cold-blooded").

Even though fishes are s some have developed the ability to remain functional even when the water temperature is below freezing and some even use natural antifreeze to resist ice crystal formation in ...

Ectotherms and endotherms manage their heat budgets very differently.

y. s, which rely mostly on external sources of heat, adopt much different strategies to the cold. s have little or no insulation.

ectotherm An organism whose internal temperature varies with that of the environment. Compare endotherm.
ectothermic Having a variable body temperature derived from heat acquired from the environment; contrasts with endothermic.

Effector a cell or organ that responds to a stimulus

Exothermic Ectothermic term used to describe an animal which controls its body temperature externally (by basking in the sun to warm up or moving to a shady place to cool off)
(exo ecto = out outer; thermo = heat) ...

s, animals — the other vertebrates and the invertebrates — that secure their heat from their surroundings (e.g., by basking in the sun). s are "cold-blooded" or poikilothermic.

Amphibians, like fish, are ectothermic; they depend upon external heat to regulate body temperatures. If the environmental temperature becomes too low, ectotherms become inactive.

Temperature: The major effect of temperature is on the enzymes controlling metabolic reactions. As a rule plants will develop more rapidly in warmer temperatures, as will ic animals. It is partly due to temperature that migrations occur.
