Thermoregulation Flashcards
The mainytainance of a constant ——- &——— tempreture is necessary for prpper phisiological functioning
Body & brain
Warm blood (——) animals they maintaion their ___&___ under changing environmental conditions
Hemothermic
Tempreture and metabolism
Body temperature is controlled by
Depends on where?
Internally regulating heat production and loss through effects of autonomic nervous system
Lower parts of brainstem and hypothalamus
Behavioral responses to temperature changes involve the function of
upper parts of the brainstem and the cerebral cortex.
Temperature perception in humans depends on the
autonomous thermoregulatory responses and thermal perception from peripheral tissues.
Tempreture homeostasis
keep the body temperature within a narrow range.
Peripheral thermoreceptors detect?
And report it to
environmental and visceral temperatures and report to the hypothalamus.
Hypothalamic temperature receptors detect
Internal temp
The thermoregulatory center initiates heat-loss or heat-gain responses in peripheral organs.
Which temp is maintained by homeostasis
Core body tempreture
Core body temp remains ___
Skin tempreture is
Constant
Variable
Temp above the range
Temp below the range
Denatures proteins and blocks metabolic pathways
Slow down metabolic pathway and afect the brain
Heat production (Thermogenesis
Basal
metabolic rate (BMR), food, skeletal muscle activity, chemical thermogenesis (epinephrine, norepinephrine, thyroxine).
Heat Loss (Thermolysis
Radiation, conduction, convection, evaporation, perspiration, respiration, and loss through urine & feces.
