9. The pea shaped structure located just under the brain that controls the function of other glands in the body is called the __________ gland.

• • • • A) adrenal B) pituitary C) thyroid D) hypothalamic

10. The gland that is of major interest to psychologists because of its involvement in the body’s immune functioning and stress response is the: • • • • A) adrenal gland.

B) thyroid gland.

C) pancreas.

D) gonad.

11. An early, popular pseudoscience called ______ attempted to study abilities and character by studying the shape of your head.
