Self-Check

Using what you have learned in this lesson about the hypothalamus, the posterior, and the anterior pituitary, choose which you think is the boss of the endocrine system. Provide as much evidence as you can to support your position. You may choose the hypothalamus, the posterior pituitary, the anterior pituitary, or a combination of these structures. Review the lesson, then complete the following multiple-choice items that will help assess your understanding of the concepts presented in this lesson.

Use the following diagram to answer the next two questions.

1. The structures labelled A and E on this diagram, respectively, are the 
   
   
   1. hypothalamus and posterior pituitary
   2. hypothalamus and anterior pituitary
   3. anterior pituitary and posterior pituitary
   4. posterior pituitary and anterior pituitary


2. The function of the structure labelled C on the diagram is to 
   
   
   1. synthesize antidiuretic hormone and oxytocin
   2. stimulate release of ADH and oxytocin
   3. stimulate production of tropic hormones
   4. regulate the levels of ADH released into the blood


3. The pituitary often is called the "master gland" because it 
   
   
   1. receives impulses directly from the brain
   2. controls every other gland and organ in the body
   3. secretes hormones that control the functions of exocrine glands
   4. produces hormones that regulate the activities of other endocrine glands


4. An abnormally large volume of urine may be produced after a person drinks alcoholic beverages. Likely, ethyl alcohol affects normal secretion of 
   
   
   1. antidiuretic hormone
   2. thyroxine
   3. cortisol
   4. aldosterone
