1. Chapter 11 Review

2. These molecules affect the organ in which they are produced?
Steroid hormones
Peptide hormones
Prostaglandins
Amino acids
Their effects include: relaxing/contracting smooth muscles of the air ways and blood vessels, secretion of other hormones, influence of blood pressure, and inflammation.

3. These 2 hormones stimulate the gonads (ovaries/testes) to mature:
Testosterone and progesterone
TSH & ACTH
GH & prolactin
FSH & LH
FSH- follicle stimulating hormone
LH- leuteinizing hormone
Both target the ovaries (stimulate the production of estrogen and progesterone) and testes (stimulate the production of testosterone).

4. Testosterone is needed for the development of:
Eggs
Sperm
Uterine lining
All of the above
Testosterone is a steroid based hormone produced by the testes and is important in sperm development and secondary sex characteristics.

5. Growth hormone
Promotes the movement of amino acids into cells
Increases the rate of cell division
Increases the rate of fat metabolism
All of the above

6. Anterior Pituitary Gland
Bonus points
Growth hormone is released by which gland?
Anterior Pituitary Gland

7. The secretion of hormones from the anterior lobe of the pituitary gland is controlled by
Releasing hormones from the hypothalamus
Releasing factors from the thalamus
Nerve impulses from the hypothalamus
Nerve impulses from the thalamus
The hypothalamus (Master gland) is the link between the nervous & endocrine systems; it controls the Anterior Pituitary Gland.

8. Hypothalamus
Anterior Pituitary
To other glands
Hormones released by the hypothalamus include: Releasing hormones- to promote hormone production from the anterior pituitary gland Inhibiting hormones -these prevent hormone production from the anterior pituitary gland

9. The endocrine system is made up of
Hormones
Glands
Gonads
Prostaglandins

10. Why? The endocrine system Affects only the reproductive system
Releases hormones into the bloodstream
Competes with the nervous system
Is made up primarily of glands with ducts
Why?
It is NOT “d” because… exocrine glands secrete through ducts NOT endocrine glands.

11. What is the function of the pancreas?
To produce sex hormones
To produce thyroxine
To produce insulin and glucagon
To produce thymosin

12. Which gland produces epinephrine (adrenaline) and norepinephrine (noradrenalin)?
Parathyroid
Hypothalamus
Pituitary
Adrenal

13. Which gland fails to produce enough of its hormone in the disease diabetes mellitus?
Adrenal
Hypothalamus
Pancreas
Parathyroid

14. Feedback inhibition means that an increase in a substance will
Decrease production of that substance
Increase production of that substance
Increase the production of other substances
Stop production of another substance

16. One way the endocrine system helps maintain homeostasis is by having
Each gland secrete only one hormone
Two hormones with opposite effects regulate certain functions
Only steroid hormones regulate important functions
The pituitary gland regulates all the other glands

17. Which gland regulates circadian rhythms?
Pancreas
Parathyroid
Pineal
Thyroid

18. Name the male gonads:
Testis
Name the female gonads:
Ovaries

19. Know the location of the glands.

20. 1. Steroid hormones can pass through the cells membrane because?
A: They are lipid soluble. 3.
2. The hormone receptor for steroid hormones is located in the cells?
A: Nucleus
3. A steroid hormone promotes? 2.
A: Protein synthesis
Steroid Hormone

21. Non-steroid hormones 1. Non-steroid hormones are made of? 1.
A: Amino acids
2. The hormone-receptor complex for non-steroid hormones is located in the cells… 2. 3.
A: membrane
3. A non-steroid hormone uses a _____ (called ___) to activate changes within the cytoplasm.
A: second messenger: cAMP
Non-steroid hormones
