Assignment task: Please answer the following questions.
Problem 1: Why is it important for the body to be able to control the diameter of blood vessels?
Problem 2: In humans, list two mechanisms used to decrease body temperature.
Problem 3: What does the galvanic skin response measure and why does it increase when we sweat?
Problem 4: What is the mild psychological stressor that can be used in the human physiology laboratory?
Problem 5: As stress increases, how would you expect the temperature of the skin to change? Increase or decrease.
Problem 6: Provide two reasons that thermoregulation is important to enzymes.
Problem 7: Define homeostasis and explain why negative feedback is preferred over positive feedback to maintain homeostasis
Problem 8: Which division of the autonomic nervous system would likely be activated if you learned that an exam you had forgotten about would start in 5 minutes. Briefly explain your answer
Problem 9: Most tissues regulated by the autonomic nervous system receive both sympathetic and parasympathetic input from postganglionic neurons. The responses are typically local. In contrast, the adrenal medulla receives input only from the sympathetic division (and only from preganglionic neurons), yet responses are observed throughout the body. Explain why?
