BIOL 3324 Exam 4
Most calcium in the body is located in ________ - Answer-the skeleton
Adults do not increase in height. This suggests that adult bones ________ . - Answer-lack cartilaginous
epiphyseal plates
The common precursor for all steroid hormones is ________. - Answer-cholesterol
Which endocrine gland is NOT correctly matched to a hormone it produces?
adrenal medulla - catecholamines
zona glomerulosa - aldosterone
hypothalamus - CRH
zona reticularis - ACTH - Answer-zona reticularis - ACTH
Which is associated with hyperthyroidism? - Answer-muscle weakness
C cells of the thyroid gland secrete ________. - Answer-calcitonin
Which of the following hormones is a part of the rapid response (rather than the prolonged response) to
stress? - Answer-epinephrine
, - Yes, epinephrine is part of the immediate or rapid response to stress. Epinephrine is released from the
adrenal medulla as a result of the increase in the sympathetic nervous system. In fact, the chromaffin
cells in the adrenal medulla act like modified postganglionic neurons.
In response to stress, which of the following changes would happen? - Answer-decreased insulin
secretion
- Yes, insulin decreases plasma glucose and during stress we need an increase in plasma glucose as well
as other body fuels. Therefore, insulin secretion would be decreased, in turn increasing plasma glucose.
Which of the following are symptom(s) of pheochromocytoma? - Answer-heart papitations
Yes, due to the increase in epinephrine, heart rate would be increased and you would feel like your
heart was pounding or racing.
Choose which condition has all of the following symptoms: hypertension, hyperglycemia, and a "moon
face."
Cushing's disease
pheochromocytoma
Addison's disease - Answer-Cushing's disease
- Yes, a patient with Cushing's would have hypertension, increased blood glucose, and an unusual fat
distribution on the face, known as a "moon face." These symptoms are due to increased levels of
cortisol and can also be seen in patients after long periods of steroid treatment.
What hormone also aids the stress response by promoting water retention and acting as a
vasoconstrictor? - Answer-ADH (vasopressin)
- Yes, ADH increases water reabsorption in the distal tubule and collecting duct of the nephron and its
secondary function is to act as a vasoconstrictor.
Which of the following hormones is currently thought to decrease plasma calcium levels in pregnant
women and children?
