Which of the following is INCORRECTLY matched with its secreting organ
TSH-Posterior pituitary
A decrease in the level of thyroixine would increase the secretion of
both TSH and TRH
A hypophysectomized rat is missing its
pituitary gland
Thyroxine is a
slow acting hormone that enters the nucleus
Which of the following hormones is regulated by a positive feedback mechanism
oxytocin
Which rat(s) was euthyroid without any injections?
the normal rat
An abnormally high level of which of the following will result in goiter
TSH
Why did the TSH have no effect on the BMR of the thyroidectomized rat
The rat is missing its thyroid gland
The injection of TSH resulted in goiter in
the normal rat and hypphysectomized
Propylthiouracil injections resulted in goiter formation in
the normal rat
Glucose is stored in the human body as
glycogen
Which hormone stimulates the breakdown of polymerized glucose
glucagon
Glucose remains in the blood stream as a result of
type 1 and 2 diabetes mellitus
Excess glucose can be found in the urine
when the transport maximum for reabsorption in the kidney tubules is excessed, as a result of type 1 diabetes or as a result of type 2 diabetes
Using this assay, glucose concentration is
directly proportional to optical density
In this experiment, optical density is measured using a
spectrophotometer
Which of the patients tested was (were) in the diabetic range?
patient 3 and 5
Which of the patients tested was (were) in the borderline range for insulin-mediated glucose uptake?
patient 2 and 4
Peptide hormones include which of the following
follicle-stimulating hormone and calcitonin
Which of the following is INCORRECTLY matched with one of its functions
Calcitonin-inhibits osteoblast activity
Which of the following is INCORRECTLY matched with its primary secreting organ
FSH-ovaries
Inhibiting osteoclast activity would prevent
osteopenia and osteoporosis
Replacement therapies for which 2 hormones were tested in this experiment
estrogen and calcitonin
Which of the following showed the greatest improvement in vertebral bone density for the rats
estrogen
The baseline T score for the rats was indicative of
osteoporosis, because their ovaries were removed
Which of the following improved the vertebral bone density of the rats
both calcitonin and estrogen
The target cells for the hormone ACTH are located in the
adrenal cortex
Tropic hormones include which of the following
both ACTH and CRH
Which of the following is NOT characterized by high levels of cortisol in the blood
Addison’s disease
Iatrogenic Cushing’s syndrome is
all of the above (often referred to as “steroid diabetes”, a result of treatment with glucocorticoid hormones, physician induced)
High levels of cortisol would normally provide negative feedback to the
anterior pituitary and hypothalamus
Which patients would be diagnosed with primary hypercortisolism?
patients 2 and 5
Which patient would be diagnosed with secondary hypercortisolism?
patient 3
Which patient would be diagnosed with secondary adrenal insufficiency?
patient 1
