A) It is synthesized by the anterior pituitary gland.
B) Its target is the thyroid gland.
C) It stimulates the release of thyroid hormones.
D) Due to negative feedback, a low level of thyroid hormones will inhibit the release of TSH.
E) All of these are true of the hormone TSH.
14) Which of the following endocrine glands is composed of 2 different regions, one consisting of glandular epithelial tissue, and the other consisting of nervous tissue?
