Thermoregulation (Hot And Cold, Physiological/behavioural)

Question 1

Stimulus (thermoregulation hot and cold, physiological/behavioural)

Answer 1

Decrease in temperature

Increase in temperature

Question 2

Receptor (thermoregulation hot and cold, physiological/behavioural)

Answer 2

Peripheral (skin) and central (hypothalamus) cold receptor

Peripheral (skin) and central (hypothalamus) hot receptor

Question 3

Modulator (thermoregulation hot and cold, physiological/behavioural)

Answer 3

A neural/electrochemical message is sent along sympathetic pathway from hypothalamus, prompting shivering and vasoconstriction

A neural/electrochemical message is sent along parasympathetic pathway from hypothalamus, prompting sweating and vasodilation

Question 4

Effector (thermoregulation hot and cold, physiological/behavioural)

Answer 4

Peripheral (cutaneous) arterioles, skeletal muscle

Peripheral (cutaneous) arterioles, sweat glands

Question 5

Response (thermoregulation hot and cold, physiological/behavioural)

Answer 5

Vasoconstriction pulls blood to the core maintaining/increase temperature and shivering creates friction creating heat

Vasodilation push’s blood to the peripheral blood vessels allowing for the loss of heat through radiation, sweat on the skin can absorb the heat and evaporate decreasing temp

Question 6

Feedback (thermoregulation hot and cold, physiological/behavioural)

Answer 6

Negative
