EXERCISE 27
Functional Anatomy of the Endocrine Glands
Gross Anatomy and Basic Function of the Endocrine Glands
1. Both the endocrine and nervous systems are major regulating systems of the body; however, the nervous system has been compared to an airmail delivery system and the endocrine system to the pony express. Briefly explain this comparison.
The nervous system is a lot more fast acting and more rapid action occurs when compaired to the endocrine and the slow path through the blood stream to create a reation.
2. Define hormone. it is a chemical put off by the body that serves as a message to make a compensation
of certain chemicals levels.
3. Chemically, hormones belong chiefly to two molecular groups, the steroids and the
amino acid-based.
4. What do all hormones have in common? it is bloodborne
5. Define target organ. the organ only respond to one particular hormone
6. If hormones travel in the bloodstream, why don’t all tissues respond to all hormones?
The hormone only bonds with certain protein receptors at the cell membrane on the inside of the cell.
7. Identify the endocrine organ described by each of the following statements.
Thyroid Adrena Pancreas Gonads Parathyroid Ovaries Thymus Pineal

1 located in the throat; 2 bilobed gland connected by an isthmus found close to the kidney 3 a mixed gland, located close to the stomach and small intestine 4 paired glands suspended in the scrotum 5 ride “horseback” on the thyroid gland 6 found in the pelvic cavity of the female, concerned with ova and female hormone production 7 found in the upper thorax overlying the heart; 8 large during youth found in the roof of the third ventricle
9. Although the pituitary gland is often referred to as the master gland of the body, the hypothalamus exerts some control over the pituitary gland. How does the hypothalamus control
