Amanda
hates her new student ID photo. Her hair looks dry, the extra weight that she’s
gained shows, and her neck looks fat. In fact, there’s an odd butterfly shaped
swelling across the front of her neck, under her chin. Amanda’s also been
feeling very tired and mentally “dull” lately, but she figures all new A&P
students feel that way. Should she visit the clinic or just wear turtlenecks?

Amanda
(from question 9 above) goes to the clinic and blood is drawn. The results show
that her T4 levels are low and her TSH levels are low. Later she is given a TSH
stimulation test in which TSH is injected and the T4 levels are monitored.
After TSH injection, her T4 levels rise. Does Amanda have problems with her
pituitary or with her thyroid gland? How did you come to your conclusion?
