Bio 139: Unit 4 Exam |Questions and Answers (Endocrine
System, Male & Female Reproductive Systems)
Which statement is incorrect? The secretion of a hormone from some endocrine glands is
controlled by - -a secretion released by an exocrine gland.
-________ are released within a tissue and affect the function of neighboring cells within that
tissue - -Paracrine signals
-________ prepare(s) the body to meet short-term stress. - -Epinephrine and norepinephrine
-Steroid hormones and thyroid hormones ________ pass across the plasma membrane; they
cause the target cells to ________ that produce the characteristic effects of the hormones. - -
can; synthesize specific proteins
-Endocrine glands differ from exocrine glands because - -exocrine glands have a duct to
carry their secretions, while endocrine glands do not.
-Nonsteroid hormones ________ pass across the plasma membrane; they cause the target
cells to ________ that produce the characteristic effects of the hormones. - -cannot; activate
or inactivate the cellular enzymes
-________ stimulates the production of sperm in testes. - -Follicular-stimulating hormone
-The hypothalamus regulates hormones from the anterior lobe of the pituitary gland using
________, while it regulates the posterior lobe of the pituitary gland using ________. - -
hormones; nerve impulses
-________ stimulate(s) the development and maturation of the female reproductive organs
and the secondary sex characteristics. - -Estrogens
-Cushing syndrome results from the - -hypersecretion by the adrenal cortex.
-________ results from a severe hyposecretion of thyroid hormones in ADULTS. - -
Myxedema
-The secretion of growth hormone is controlled by - -a releasing hormone and an
inhibiting hormone from hypothalamus
-The secretion of estrogens is controlled by - -LH
-________ hormones bind with an intracellular receptor to form a ________, which activates
specific genes - -Steroid and thyroid; receptor-hormone complex
, -The hormone(s) that regulate(s) wake-sleep cycles is(are) ________ produced by the ________
gland - -melatonin; pineal
-The hormone ________ stimulates movement of glucose into body cells and the conversion
of glucose into glycogen - -insulin

hypoglycemia
-Which of the following endocrine glands is directly controlled by the autonomic nervous
system: - -adrenal medulla
-The hormone that causes strong contractions of the uterus during labor is: - -Oxytocin
-Glucocorticoids (cortisol):
a. increase the breakdown of fats
b. increase the breakdown of proteins
c. increase blood glucose levels
d. decrease inflammation - -All of the above
-Which of these stimulates the secretion of ADH: - -elevated blood osmolality
-A second messenger in the action of many water-soluble hormones such as peptides is: - -
cAMP
-The hormone that stimulates milk production in the mammary gland: - -Prolactin
-Glucocorticoids are steroid hormones produced by the: - -adrenal gland
-Which statement is NOT true of hormone effects on the kidneys: - -aldosterone decreases
the reabsorption of sodium ions
-Which statement is NOT true of hormone effects on bones: - -hGH decreases the rate of
mitosis in growing bones
