Thermoregulation Mechanisms

What is the process called when our body uses muscles to maintain core body temperature?

• Blood circulation

• Thermal regulation

• Muscle contraction

• Neuronal signaling

Which part of the brain perceives that it's really warm outside?

• Cerebellum

• Anterior hypothalamus

• Posterior hypothalamus

• Frontal lobe

What part of the hypothalamus responds to temperatures that make it feel like we're on fire?

• Frontal lobe

• Posterior hypothalamus

• Anterior hypothalamus

• Cerebellum

Which type of muscle lines our arterioles?

• Striated muscle

• Skeletal muscle

• Cardiac muscle

• Smooth muscle

What is the process called when arterioles become wider in response to hot temperatures?

• Contraction

• Vasoconstriction

• Vasodilation

• Relaxation

What happens to blood flow in the skin during vasodilation?

• Increases

• Stays the same

• Stops

• Decreases

What type of muscle contracts when it's cold and produces energy through an exothermic reaction?

• Skeletal muscle

• Smooth muscle

• Striated muscle

• Cardiac muscle

What is the purpose of skeletal muscle contraction in response to cold temperatures?

• To produce energy

• To cool down the body

• To relax the muscles

• To increase blood flow

What is the process called when arterioles narrow in response to cold temperatures?

• Relaxation

• Contraction

• Vasoconstriction

• Vasodilation

What happens to blood flow in the skin during vasoconstriction?

• Stays the same

• Increases

• Stops

• Decreases
