Increase heart rate
What is Relation of calcium in blood with TSH?
TSH or Thyroid Stimulating Hormone,which is released from the pituitarygland in the brain, stimulates the C cells in the thyroid gland to produce calcium. If too much calcium is in the blood there is possibly an oversecretion of TSH from the pituitary gland.
Who control the secretion of epinephrine and norepineprine by the adrenal glands?
Control of secretion of epinephrine and norepinephrine is regulated primarily by descending sympathetic signals in response to stress, including exercise, hypoglycemia, and hemorrhagic hypovolemia

Why don't more physicians prescribe Armour to supplement the thyroid?
I have heard it said that it is because Armour 1. may cause more adverse reactions/side effects in some people, 2. can not be as adequately calibrated for dosage as synthetic drugs, 3. some patients do not absorb it in the same way as synthetic drugs or as some physicians say do not absorb as well.
I really believe it has to do with the limits of their education, experience and expertise and not the efficacy of Armour.

Gow does the endocrine gland function?
The endocrine gland functions by secreting hormones directly into the bloodstream, which act as chemical messengers to regulate various bodily processes. These hormones influence metabolism, growth, mood, and reproductive functions, among others. Each gland responds to specific signals from the body, ensuring that hormone levels are balanced and appropriately timed for physiological needs. Overall, the endocrine system plays a crucial role in maintaining homeostasis and coordinating complex bodily functions.
Should thyroid uptake scan be done if you have had thyroid removed?
A thyroid uptake scan wouldn't normally be needed unless it is suspected that thyroid tissue was missed during surgery (sometimes thyroid tissue can be found in other areas of the body), or the reason for the surgery was cancer and the removal of all the tissue is vital.
