Problem: A 23-year-old woman visits her family physician with complaints of a 12-month history of increasing nervousness, irritability, and palpitations (a noticeable increase in the force of her heartbeat). Furthermore, she feels very warm in a room when everyone else feels comfortable. Her skin is unusually warm and moist to the touch. She has lost 30 pounds of body weight over this period despite having a voracious appetite and increased food intake. Reflect and Review #1
Describe the general principles of the control of body temperature (see Figures 16.16 through 16.18). What may have caused her skin to feel warm and moist?
