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. _____________________________________________________________________________________________ ______ _____________________________________________________________________________________________ ______ _____________________________________________________________________________________________ ______ 2.

Review Sheet 27

7. The table below lists the functions of many of the hormones you have studied. From the keys below, fill in the hormones responsible for each function, and the endocrine glands that produce each hormone. Glands may be used more than once. Hormones Key: ACTH ADH aldosterone calcitonin cortisol epinephrine Function Regulate the function of another endocrine gland

Glands Key: estrogens FSH glucagon insulin LH oxytocin progesterone prolactin PTH T3 /T4 testosterone TSH adrenal cortex adrenal medulla anterior pituitary hypothalamus ovaries pancreas parathyroid glands posterior pituitary testes thyroid gland

Hormone(s) 1. 2. 3. 4.

Gland(s)

Maintenance of salt and water balance in the extracellular fluid

1. 2.

Directly involved in milk production and ejection

1. 2.

Controls the rate of body metabolism and cellular oxidation Regulate blood calcium levels

8. 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 both anterior and posterior...
