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.
Can you live without the endocrine system?
Probably, for about a minute or so. Or however long it takes for the heart and brain to become necrotic.
WELL YOU BECOME ADDICTED TO ADRENALINE BY USING IT CONSTANTLY
**********
If you constantly put yourself in a scary or exciting situation constantly, then you will get addicted to that feeling. The more you use adrenaline, the more you need it to feel satisfied.
But don't do it.
**********
There are physiological mechanisms which explain how adrenaline is addictive.
Adrenaline releases glucose into the blood as well as other effects such as increased heart rate and breathing rate.
Where is the boys hormone produced?
Female hormones are oestrogen and progesterone and are produced in the pituitary gland in the brain and ovaries. In males the hormones are testosterone and are produced also in the pituitary gland and the testes.
Does a stroke affect the nervous or endocrine system how stroke affects the endocrine system?
It affects the nervous system.
It affects both those systems along with many others. It effects the endocrine system, because the hypothalamus and the pituitary gland, both secreting organs in the endocrine system, are located in the brain. If a stroke were to occur in those regions, the hypothalamus or the pituitary gland would not be able to secrete the hormones needed to keep homeostasis. The brain also controls the nervous system. So, a stroke does affect both.
Why is iodine important for proper thyroid function?
It is used by the Thyroid gland to produce its hormones called: T1, T2, T3, and T4. If not enough iodine is available for it to produce these hormones a swelling of the Thyroid will develop called "Goiter".
Can you drink coffee before a thyroid test?
If you are only being tested for thyroid function, and your doctor has not asked you to do otherwise, you do not need to fast.
If you are undergoing a physical exam for your hyperthyroidism, it is allowed, although unwise to indulge in coffee before the exam, as caffeine can make your hyperthyroid symptoms seem much worse. This would potentially lead the physician to get an unclear impression of the impact of the dysfunction to your system. With an altered impression, it is possible you could end up over-treated for your condition.
Does the thyroid cause stabbing pain?
imagine you burned yourself/ the pain you get for days after hot pulsing stabbing pain- well that's what the right side of my thyroid feels like all the time and it is most painfull and annoying. have just had 2nd biopsy on 1.4cm nodule awaiting results been a week now. so yes is the answer to your question

When endocrine glands are activated by other hormones it is what type of stimuli?
This is referred to as hormonal stimulation and is readily illustrated by the activity of the pituitary gland, which controls the activity of all of the other endocrine glands. The thyroid hormones, e.g, regulate the body's metabolic rate but, in and of itself, the thyroid gland does not how much hormone to produce. This function is reserved for the pituitary gland which secretes thyroid stimulating hormone (TSH) which, in turn, stimulates the thyroid to produce its hormones. As thyroid hormone levels increase they, in turn, "stimulate" the pituitary gland to reduce its TSH stimulation. In actuality, a steady-state, mediated by their respective hormones, exists between the pituitary and the thyroid that maintains a constant level of thyroid hormones and, therefore, a relatively constant metabolic rate.
What is the function of the thymosin hormone?
Thymosin is a hormone produced by the thymus and it works with the lymph nodes and white blood cells, for example, to buildup immunity.

What is papillary cancer of the thyroid?
Papillary thyroid cancer is considered the most common form of thyroid cancer. According to ThyroidAwareness.com, papillary thyroid cancer is most commonly diagnosed in women 30-40 years old and it most frequently spreads to the neck lymph nodes.
posterior lobe release the hormone oxytocin and antidiuretic hormone.
The entire Nervous system in the body, breaks down into smaller "systems" containing special nerves with special functions.
The body's fight or flight response is a natural defense mechanism controlled by the Sympathetic nerves in our nervous system.
The job of the Sympathetic nerves is to raise our heart rate, blood pressure and so forth when we are faced with a stressful situation.
These changes in the body will "tell" the body how to respond to emotions that are running high during a situation that is stressful past the point of "normal".
Do we stay and "fight" this situation or do we remove ourselves from this situation (flight)
Think of "Sympathetic" as the body "feeling sorry for you", having sympathy for you when you are under a lot of stress".
< SYMPATHETIC = SYMPATHY >
The changes that occur will eventually need to return to normal.
The heart rate will need to decrease, and blood pressure return to a normal level.
The nerves that will accomplish this, after this stressful situation is over, are called the Parasympathetic nerves.
----
These nerves are part of what is called the AUTONOMICNERVOUS SYSTEM.
Remember: If our heart rate - blood pressure, anything like this changes in the body, it is an AUTOMATIC response, as in INVOLUNTARY.
(The smaller system controlling voluntary movements is the SOMATIC NERVOUS SYSTEM)
The breakdown of the entire system contains:
CENTRAL NERVOUS SYSTEM, which is the Brain & Spinal Cord.
The PERIPHERAL NERVOUS SYSTEM containing the nerves. (2 main types)
* AFFERENT Nerves which are sensory nerves. * transfers "sensory" information * EFFERENT Nerves which are motor nerves. * transfers "motor" information
The Peripheral Nervous System (above) contains the
SOMATIC & AUTONOMIC SYSTEMS.
(the "smaller" systems discussed above)
The Autonomic System contains your Sympathetic & Parasympathetic Nerves.
The functions of the Nervous system as a whole are to:
# COLLECT information (Nerves - Peripheral Nervous system) # TRANSFER this information (Spinal Cord - Central Nervous system) # ANALYZE this information (Brain - Central Nervous System)
