Endocrine System
The endocrine system is made up of glands which control and coordinate body functions and maintain homeostasis inside the body.

A 44.5 means that your TSH level is not within the normal range. While a normal TSH varies from person to person, the range that is typically followed by physicians is .3 to 4.5. A .3 is on the hyperthyroid (overactive thyroid) end and a 4.5 is on the hypothyroid (under active thyroid) end of the spectrum. Talk with your doctor about any questions or concerns about the results, as well as any symptoms you are experiencing.
How does the endocrine system compare to the nervous system in regulating homeostasis?
Nervous System mainly the hypothalamus secretes different relasing and inhibiting hormones that controls the secretions of various hormones from anterior pituitary as well as secretes two important neuro-hormones viz. oxytosin and vasopressin. thus nervous system along with endocrine system works together to maintain homeostasis.
Why isn't the neurohypophysis or posterior lobe of the pituitary gland a true endocrine gland?
It is only a hormone storage area that receives hormones from the hypothalamus for release. Since it does not make its own secretions (it only stores the neuroendocrine hormones made by the hypothalamus) it is not considered a true endocrine gland.
How does endocrine regulate itself?
In order to answer this question we must all understand what the organs are that make up the endocrine system. The hypothalamus is the master control found in the brain at the base of the optic chiasm. The hypothalamus releases a hormone in the pituitary gland, controls the blanace of water, sleep, temperature, appetite, blood pressure and such. There is much more but that is a start.....
Hormones!
homeostatic conditions also vary across the body - for example, a high acidic level must be maintained in the stomach, this level is maintained by the hormone Gastrin, which is released when the stomach is stretched by food, this hormone targets the production of HCl (Hydrochloric Acid) in the stomach
Another, possibly the most important homeostatic condition is water, which can be maintained by the hormone ADH (anti-diuretic hormone) which controls how permeable the distal convoluted tubules and collecting tubules are, the increase of permeability makes the water that would usually go straight into the urine go back into the body, this lowers water loss and increases urine concentration. this hormone is only released when the body is dehydrated, but when the body has too much, this is removed from the body and most of the water that would be reabsorbed into the body is just removed in the urine.
Hormones send messages to different organs and organ system to turn on/off speed up/slow down activities of those tissues
This is the main way we maintain homeostasis actually, since the endocrine system releases chemicals known as hormones. These hormones are sent via the blood to specific spots in the body to control things like blood sugar, heart rate, etc.
Tonsil is a endocrine gland or not?
While the tonsils are a gland, they are a gland of the immune system and not of the endocrine system.
List of different glands of the body?
An endocrine gland is a ductless gland that produces and secretes hormones into the blood or lymph nodes, affecting specific target tissues throughout the body. Endocrine glands include the pituitary, pineal, hypothalamus, thymus, thyroid, parathyroid, adrenal cortex, adrenal medulla, islets of Langerhans and gonads ie testes and ovaries.
What are the names of the small glands attached to the thyroid glands?
Those are called the parathyroid glands.
What is know as damage to the retina of the eye caused by diabetes mellitus?
Because of the viscous blood when there is hyperglycemia in diabetes mellitus, the blood circulation in the eyes becomes slow or sluggish. This will result in blurring or vision of the person affected.
Does the over production of tsh cause hypothyroidism?
No. An overproduction of TSH would cause hyperthyroidism.
What is the major area where the nervous system and endocrine system interact?
That would be the hypothalamus, the gland of homeostasis.
It causes an egg to mature in the ovary and stimulates the production of oestrogen.
I have high esr in my blood. 70 mm.i need normal esr.please can you give me best treatment.
Can half of the thyroid gland be removed?
Yes, half of the thyroid gland can be surgically removed. This surgery is known as a partial thyroidectomy. It is common that after half of the thyroid gland is surgically removed that a patient will need to start taking daily thyroid medication.
What is the main structure for endocrine system?
Pick three:
Adrenal Glands
Hypothalamus
Ovaries
Pancreas
Pineal Gland
Pituitary Gland
Testes
Thymus
Thyroid Gland
What are three different jobs that hormones perform?
hormones are very important.main functions include:- the way the body uses food; growth; sex and reproduction; the regulation of the composition of the blood; the body's reaction to emergencies and the control of hormones themselves.
Does the thyroid hormone require iodine for synthesis?
The United States Food and Drug Administration recommends 150 micrograms of iodine per day for both men and women. This is necessary for proper production of thyroid hormone. Natural sources of iodine include sea life, such as kelp and certain seafood, as well as plants grown on iodine-rich soil. Salt for human consumption is often enriched with iodine and is referred to as iodized salt.1

What hormones are produced by thymus gland?
The hormones the thymus produces are:
o TF - thymic factor
o Thymosin
o THF - thymic humoral factor
o Thymopoietin.
These hormones stimulate the development and maturation of white blood cells which are called T cells.
thymosin
Can someone survive without their thyroid gland?
Yes it is very possible to survive without a thyroid gland. After the surgerical removal of the thyroid, say abt 4-6weeks after, the patient is given a pill of radioactive iodine. After this, the patient would be on iodine pills for life so as to aid the production of the thyroid hormone which no humna can survive without. I hope Ive been able to answer your question.
A deficiency that causes the thyroid gland to swell is iodine deficiency. This is also believed to be the main cause of goiter.
How long after having radiation for your thyroid can you be around your young children?
If you are receiving radiation treatment for cancer, you can still be around kids. The radiation, and the cancer, are not contagious.
Another Answer:
It depends on whether you just receive radiation, or if you have radioactive implants. If you just receive radiation therapy, such as gamma radiation from Cobalt-60, then you are not radioactive when you leave the facility. If you have implants, however, such as around the prostate gland in certain forms of therapy, you are radioactive, and you need to ask your radiation technologist and doctor what your limits are relative to being around children.
Note: Some radiation treatment, particularly neutron bombardment, can cause activation of some of your atoms into a radioactive form. To be safe, talk to your doctor, etc. in any case.
Also, bone scans, heart scans, and other types of scans where you are injected with a radioactive tracer, such as Technicium-99M, do make you radioactive for a short while, often just a few days. Again, talk to your doctor.
What does a diffusely heterogeneous thyroid mean?
it means: nodule-a rounded lump or knot; heterogeneous means "composed of unlike parts. Therefore a rounded lump composed of dissimilar tissues on the thyroid (gland) located in the base of throat region. may or may not require medical attention.
What is difference between t3 and t4 thyroid hormones?
TSH is commonly accepted today as the first-line diagnostic test for overall thyroid function. In general, a normal TSH level (0.3-4.5) indicates normal thyroid function. If the TSH is high or low, then T4 and T3 (and their "free" forms, FT4 and FT3) are evaluated to narrow the diagnosis.
What does nodular thickening of the adrenal glands mean?
Nodular thickening of the adrenal gland means that cancer could be present. It would normally be treated by surgical removal of cancerous tumors.
Does liver play an important role in both the immune and endocrine systems?
yes. the endocrine part is the hormone secreting cell (hepatocytes).
The four glands, each of which is the size of a grain of rice, that are located around the surface of the thyroid gland is the parathyroid gland. The parathyroid glands control calcium regulation, which is the amount of calcium that is in the blood and within the bones.
