Thermoregulation Flashcards
When body temperature rises
Free nerve endings in the skin sense tempature
Send sensory electrical signals up the hypothalamus
And the hypothalamus respond with sympathetic signals back that stimulate the sweat glands
Sweating allows for
Evaporative heat loss
Increased dermal blood flow allows for
Radiation heat loss
Hypothalmus decreases metabolic rate
To slower atp because atp causes heat and if we are too hot it will slower
When body temperature drops
Free nerve endings in the skin sense tempature
Send sensory electrical signals up to the hypothalamus
Hypothalmus responds with sympathetic signals back that stimulate arrector pillow muscles
Arrector pillow muscles cause
Goose bumps-the hair stands up to trap heat
Decreased body blood flow
Will help to conserve body heat
Hypothalmus increases metabolic rate
Faster metabolism generates more heat
Motor output causes involuntary muscle contractions
Which generates heat
