Correct Answers
The hypothalamus senses hormone levels and __________ ✅secretes releasing
hormones
Pituitary stimulus causes endocrine gland to _______ ✅secrete a specific hormone
(stimulating hormones)
When you think endocrine you should think ✅feedback
The hypothalamus secretes ________ which stimulates the _______ gland
✅corticotropin; pituitary
The hypothalamus secretes _____ because cortisol levels are low ✅-
The pituitary gland secretes _______ which in turn stimulates the _______ gland to
secrete the hormone cortisol ✅adrenocorticotropic hormone (acth); adrenal gland
If a gland is overactive... ✅t3/t4 will be off the charts and there will be no tsh in the
blood-> non-detectable
As hormone levels increase the hypothalamus and pituitary _____ ✅shut down
How does endocrine feedback work in a negative loop ✅pituitary sends thyroid
stimulating hormone bc there is not enough thyroid in the blood
Example of negative feedback ✅as cortisol levels in the bloodstream rise, the pituitary
sense the increased level and shuts off the stimulus to the adrenal gland
Endocrine disease: 3 main types of conditions ✅hormone deficiency, hormone excess,
hormone resistant
Hormone deficiency means ✅not enough
Hormone resistance means ✅not working effectively (hormone present but not working

Diagnosis of endocrine disorders ✅- *blood levels* of hormones are the *most
important diagnostic tools* in endocrine disorders.
- *urinary hormone levels* are useful for some conditions. Urinary collection over 24
hours often can provide useful information in the analysis of metabolic function.
- suppression tests
- ct scan/mri (in pituitary or brain)
- ultrasound (in adrenal or thyroid)
Treatment of endocrine disorders ✅-hormone replacement therapy is used with
hormone deficiency. Dosage schedules attempt to mimic physiological hormone
production.
-suppression of hormone overproduction is accomplished medically or surgically. (this
could knock off the gland or make the hormone work for efficiently) ex: in type 2
diabetes
What is diabetes insipidus? ✅posterior pituitary lack of antidiuretic hormone (adh) also
called vasopressin
When there is a lack of adh, sometimes the body can _______ ✅fix itself but not
always it depends on the damage
Insipidus refers to ✅the back part of the pituitary (posterior)
Causes of di ✅1. Caused by a lack of secretion of adh from the posterior pituitary
2. When the kidney fails to respond to adh (or stimulus of pituitary)
What happens if you lack adh ✅you have large urine volumes excreted
What happens if you have too much adh ✅you retain too much water
Adh is monitored and regulated by the ______ ✅posterior pituitary
What causes the malfunction of the posterior pituitary ✅1. Benigns pituitary
melanomas
2. Tumor on pituitary
