Thermoregulation Flashcards
What are the basic processes where we lose heat
Radiation
Evaporation
Conduction
Due to infrared heat rays that our body is emitting
Radiation
When heat is transferred to an object in contact with the body
Conduction
This is a random kinetic movement of molecules
Brownian movement
When new air molecules come in contact with the body
Air convection
Known as the internal heat of the body
Core temperature
Reflects the ability to lose heat
Skin temperature
This is an important determinant for core temperature
Basal Metabolic Rate
What controls sweating
Pre-optic and anterior hypothalamic nuclei
What is the primary stimulant of sweat
Acetylcholine
Acclimatization of the sweat gland is due to
Aldosterone
What controls for shivering
Posterior hypothalamic area
The body must maintain what temperature
37.1
What is the most active thyroxine that would generate heat
T4
If you increase the skin temperature what happens to the set point
Decrease
