2. _____ B. Islets of B. Calcitonin B. Promotes uptake of glucose by cells
Langerhans
3. _____ C. Thyroid C. Follicle- C. Promotes body growth during
stimulating adolescence
Hormone
4. _____ D. Parathyroid D. Growth Hormone D. Increases metabolism
5. _____ E. Pineal gland E. Insulin E. Inhibits release of calcium from the
bones
6. _____ F. Pituitary F. Luteinizing F. Produces estrogen and progesterone
Gland Hormone
7. _____ G. Melatonin G. Sleep cycles, reproductive cycles in
many mammals
8. _____ H. Oxytocin H. Stimulates the release of calcium
from the bones
9. _____ I. Parathyroid I. Stimulates egg maturation in the
Hormone ovary and release of sex hormones
10. ____ J. Thyroxine J. Stimulates “fight or flight” response.
II. Let’s Analyze (10 points)
Read the statements carefully. Encircle the letter of the correct answer.
1. After eating a banana, which hormones would be expected to increase?
A. Insulin B. Glucagon C. Parathyroid hormone D. Prolactin
2. Which of the following hormones would be expected to increase if you were studying all
day for a test and skipped breakfast and lunch?
A. Calcitonin B. Glucagon C. Growth hormone D. Insulin
3. Which of the following is both an endocrine and exocrine gland?
A. Adrenal glands B. Liver C. Parathyroid glands D. Thyroid gland
4. Antibodies directed against pancreatic cells result in these cells’ destruction. What
laboratory abnormality might be seen in this scenario?
A. Depressed serum calcium C. Elevated serum glucose
B. Depressed serum sodium D. Elevated serum calcium
5. Which of the following statements regarding pituitary hormones is false?
A. The hypothalamus makes oxytocin and antidiuretic hormone, which are transported to
the pituitary for storage.
B. Antidiuretic hormone, released by the pituitary, causes urine volume to increase and
blood volume to decrease.
C. Hyposecretion of follicle-stimulating hormone or luteinizing hormone leads to sterility
in both males and females.
D. Luteinizing hormone, a pituitary hormone, triggers ovulation of an egg from the ovary
and causes the ruptured follicle to produce progesterone and some estrogens.
6. Why can a single endocrine hormone produce a wider spread of responses from within the
body than a single nerve cell?
A. Endocrine hormones only target a very small number of precise responses.
B. Nerve cells and blood work together. The endocrine has nothing to do with the nervous
system.
C. A single hormone can target many different responses, whereas a nerve only targets a
single response.
D. Blood can carry all the same hormones throughout the body simultaneously, producing
responses all over the body; nerve cells can only target a small number of cells.
7. What are the symptoms of diabetes mellitus?
A. Excessive thirst B. Excessive urination C. Excessive hunger D. All of the above
8. What regulates most of the endocrine system?
A. Hormone-gene complexes C. Negative feedback mechanisms
B. Hormone-receptor complexes D. Positive feedback mechanisms
9. Which of the following is correctly paired?
A. Calcitonin; thyroid C. Glucagon; liver
B. Glucagon; kidney D. Melatonin; liver
10. What happens to your body if you drink a liter of water very quickly?
A. There will be a decreased secretion of oxytocin
B. There will be an increased secretion of oxytocin.
C. There will be a decreased secretion of antidiuretic hormone.
D. There will be an increased secretion of antidiuretic hormone.

III. Check Your Understanding (5 points each)
Apply the concepts you have learned to answer each question. Write your answers in the
space provided.
1. Knowing that lack of iodine in the diet causes a disorder affecting the thyroid gland, what
can you infer about the hormone thyroxine?
2. Diagnose the endocrine issues using your knowledge on endocrine system: An elderly
patient who is having chronic trouble falling asleep at night.
Score Rubric for Question 1 and 2
5 The student’s response demonstrates an in-depth understanding of the hormone thyroxine and
melatonin, and the disorders associated with these hormones.
The student completes all key components of the task accurately and communicates ideas
effectively.
Infers the importance of thyroxine as secreted by thyroid gland (question 1)
Explains the relationship of iodine and thyroxine (question 1)
Gives the correct diagnose on an elderly patient having troubles sleeping at night (question 2)
Explains the gland that is affected when one experiences difficulty in sleeping at night, and
points out the hormone that is responsible for this (question 2)
Where appropriate, the student uses a higher level of reasoning skills that may include applications,
procedures, etc.
The response contains no errors.
4 The student’s response demonstrates a good understanding of the hormone thyroxine and melatonin,
and the disorders associated with these hormones, although less important ideas or details may be
overlooked or misunderstood.
The student completes most important aspects of the task accurately and communicates clearly.
The student’s logic and reasoning may contain minor flaws.
The response contains minor errors.
3 The student’s response demonstrates a limited understanding of the hormone thyroxine and
melatonin, and the disorders associated with these hormones
The student completes some parts of the task successfully.
The response contains errors.
2 The student’s response demonstrates a basic understanding of the hormone thyroxine and melatonin,
and the disorders associated with these hormones.
The student completes only a small portion of the task.
The student’s response contains major errors.
