describe the roles and relationships of the hypothalamus and
pituitary gland to other endocrine glands and tissues. give an
example that shows these relationships
The hypophysis is unit formed by the pituitary and the
hypothalamus. These two glands are connected by the blood flow in
what system?
a. Hypophyseal portal system
b. Supraoptic portal system
c. Paraventricular portal system
d. Hypothalamic portal system
What is true about the anterior pituitary gland?
A. there are different types of endocrine cells found there that
produce different
hormones
B. all hormones are released from the anterior pituitary through
the hypothalamic-hypophyseal
portal system
C. this gland produces LH and FSH which are both amine hormones,
known as
gonadotropins
D. the levels of most of these hormones are controlled by a
positive feedback loop
The hypothalamus-pituitary complex can be considered as the
master control center for the endocrine system.
Contrast how the hypothalamus communicates differently with the
anterior pituitary gland compared to the posterior pituitary
gland.
Using a specific example, describe the process by which the
hypothalamus can direct the secretion of an anterior pituitary
gland hormone and the effects at the target organ or tissue.
