Summary Introduction
Introduction:
The endocrine system operates with the help of chemical messengers, which are produced by various organs or glands. The hormones are secreted directly into the bloodstream to maintain equilibrium of the body. The major endocrine glands of the body are thyroid, pancreas, adrenal, pituitary, pineal, hypothalamus, testes, ovaries, and parathyroid glands.

On a realistic drawing of the endocrine glands in the body (such as a photocopy of Figure 17.1), indicate the gland associated with (a) cretinism, (b) diabetes mellitus, (c) acromegaly, (d) secreting thyroid-stimulating hormone, (e) secreting a hormone that regulates the nightly activities of our circadian rhythms, (f) secreting estrogens, (g) secreting DHEA.
1) Gross Anatomy and Basic Function of the Endocrine Glands
a)Both the endocrine and nervous systems are major regulating systems of the body; however, the nervous system has been compared to a text message, and the endocrine system to mailing a letter. Briefly explain this comparison.
b) Chemically, hormones belong chiefly to two molecular groups, the___ and the___
c) If hormones travel in the bloodstream, why don't all tissues respond to all hormones?
Endocrine downregulation ...
a) ... occurs in target cells that respond to hormones that are present in constant amounts in the blood.
b) ... leads to the increased sensitivity of the target organ to the hormone.
c) ... leads to a decrease in the number of receptors in the target cell.
d)... occurs in part due to increased receptor synthesis in the target cell.
