Module 6 Problem Set - Portage A&P 1
Introduction to the Endocrine System
1. Does the nervous system or the endocrine system react faster to external/ internal stimuli?
2. What are the two major groups of hormones and what are their derivatives?
3. Hormones can react with cells that have what on their cell surface?
4. Do peptide or steroid hormones react faster?
5. True or false: Endocrine glands contain ducts and secrete their contents directly into an
epithelial lining. - ANS-Introduction to the Endocrine System
1. The nervous system
2. 1- Peptide (derived from proteins and catecholamines)
2- Steroids (derived from cholesterol)
3. Receptor
4. Peptide
5. False
Endocrine Organs
6. True or false: the hypothalamus and pituitary glands are in the abdomen.
7. The adrenal glands are found on top of the ______.
8. Be able to label the primary endocrine organs.
9. Name three secondary endocrine organs. - ANS-Endocrine Organs
6. False
7. Kidneys
8. See figures in module
9. Heart, thymus, kidneys, gonads
, The Negative and Positive Feedback Systems
10. Describe homeostasis in the body.
11. During negative feedback a hormone level is high. What happens to hormone production?
12. The action of oxytocin works through positive or negative feedback? - ANS-The Negative
and Positive Feedback Systems
10. (set-point) is a range in which the body acts to maintain all its levels for function.
11. The brain detects the hormone level is too high and hormone production is shut off.
12. Positive feedback.
The Hypothalamus and Pituitary glands
13. Why are the neurons in the hypothalamus called neurosecretory cells?
14. Axons travel from the hypothalamus terminate in what region of the brain?
15. The posterior pituitary gland stores what two main hormones?
16. What does ADH do in the body?
17. What hormone stimulates the release of milk from the mammary glands? - ANS-The
Hypothalamus and Pituitary glands
13. They are cells that respond to neurotransmitters and produce hormones.
14. Posterior pituitary
15. ADH and Oxytocin
16. ADH promotes the reabsorption of water from the collecting ducts, which receive urine
produced by nephrons within the kidneys. As the blood becomes dilute, the hormone no longer
is released until it is needed again.
17. Oxytocin
The Anterior Pituitary
18. What major hormones are secreted from the anterior pituitary gland?
