When would you use technetium in a nuclear medicine thyroid scan?
If I-123 was not available and that is the only reason ever. Some places use Tc99m because it is cheaper and faster than I-123. But i-123 was developed because it was and is better than straight Tc99m
What is excessive hunger associated with diabetes mellitus?
First of all he have diabetes because he is always hungry and it caused him to over-eat.
The way that the diabetes can cause him to be hungry (if we assume it is not the other way around - as above) is that if it is not well controlled the sugar is not being taken up from the blood and being used by the cells. You end up with a situation where the sugar is high in the blood and low in the cells and so they send out signals trying to tell the body that they need more food.
What happens if the Thyroid Gland is swollen?
There are different reasons for the pituitary gland to be "swollen". It could be something as simple as having depression, or if you have recently had a baby. Or it could be something more serious like lymphocytic hypophysitis or pituitary tumor or pituitary apoplexy. You would really need to see a pituitary specialist for it.
The thyroid gland secretes what?
Many hormones. Thyroxine (T4), Triiodothyronine (T3), and Calcitonin are the ones that are important! For more info, read my next paragraph. If that's all ya need, then hope that helped!
T4 is involved with cell metabolism; it increases the metabolic rate of cells. T4 speeds up cells and produces heat. T3 on the other hand is associated with body temperature, growth, and heart rate. Calcitonin reduces blood calcium levels, targeting the kidneys, small intestine, and the bones.
One of the functions of FSH in the menstrual cycle is for development of the primary follicle during the first few days of the menstrual cycle, and there is a small peak of this hormone between approximately days 1-6.
As oestrogen levels increase (oestrogen is secreted by the theca interna of the secondary oocyte) this feeds back negatively, thus decreasing the level of FSH until approximately day 12. Oestrogen levels reach a peak between days 11 and 12, and then start to decline. As levels of oestrogen decline, FSH levels start to increase once more, and there is a small peak of FSH on day 14 when ovulation occurs.
FSH is responsible also for the choice of the dominant follicle; a woman has many follicles, but only one (or 2 if there are dizygotic twins) will mature. This appears to depend on the number of FSH recpetors on the surface of the follicle, i.e the follicle that has most receptors will be the one which matures.
To answer your question, then, I would say that the 2 main functions of FSH in the menstrual cycle are:
1) The initiation of follicular development, and general development of the primary follicle
2) Choice of the dominant follicle, i.e the follicle which will be ovulated.
I hope that helps: I am currently trying to answer the same question, and struggled to find a second function of FSH other than the initiation of follicular development!
What effect does TSH have on the thyroid?
It controls the body's metabolism namely regulating the rate at which the body consumes oxygen and produces ATP, which the cells use as energy.
Because of this it has diffuse effects on all systems in the body. Nervous, Cardiac, Integumentary, GI, just about everything in you body will be altered when T3, or T4 levels change either up or down.
How long should I fast for a tsh blood test?
No. Fasting is only required for lab tests which examine lipids, sugars (blood glucose, glycohemoglobin, etc.) and amino acids.
What are the symptoms of hypersecretion of Oxytocin?
What type of common disease id related to oxytocin
Primary purpose of the endocrine system?
Your endocrine system helps your body regulate the hormones and chemicals in your system. Since your brain and many other organs respond to hormones, it is important that you have a health endocrine system.
What hormones target the gonads?
There are a few hormones that act on the gonads and they are different for both the male and female reproductive systems.
In females, the gonads are the ovaries. The hormones include:
In males, the gonads are the testes. Their corresponding hormones include:
Can you live without your adrenal gland?
no we cant live without our adrenal gland as it has very important role in our physiology and it secreat some hormones which are necessary for living like aldosterone which is important in maintaining BMR of body, cortisol which are known as life protecting hormone as maintain blood glucose level etc..
Yes you can and many people do. People can live with one or none. Life is maintained with hydrocortisone and fludrocortisone, two medications that replace the cortisol, sodium that your system no longer makes. You are just adrenal dependent. You could go into an adrenal shock if you have a major illness, accident or shock as your body does not make the "fight or flight" cortisol. You then need to inject or be injected with a powerful steroid called dextramethesone within a very short time or you will go into adrenal crisis. The end result of that is your organs shut down one by one and you die. You need to wear a MEDICALERT bracelet that states that you are adrenal insufficient and steroid dependent. Glad I could help with this information.
How is FSH used in the artificial control of fertility?
Fsh is follicle stimulating hormone. It is secreted by the pituitary gland and, very simply, it helps the ovaries to release eggs. If a woman is short of this hormone the ovaries may not develop properly, and ovulation may not occur. It is also necessary in men for the development of the testes and the production of sperm. If it is supplied artificially it can improve fertility.
What do you put medicine into?
It depens with medicine you need to inject and in which place of your body.
For deep muscles, you use longer needles (1 to 1 1/2 inches).
It also depens of the drug viscosity. For "oily" products, you need to use bigger needles (18 to 22 gauges).
For regular subcutaneous injection (liquid form) you can use 1 inch needle with a gauge of 27 to 30.
How do endocrine glands differ from other glands?
Endocrine glands secrete hormones and exocrine glands secrete enzymes. Endocrine glands secrete hormones directly into the blood stream, while exocrine glands secrete enzymes through ducts. endocrine is ductless gland exocrine retain their duct, exocrine empty through their duct to epithelial such as sweat, oil, glands, liver and pancrease

What is true regarding endocrine glands?
Endocrine glands:
- are ductless ("endo" means "internal") and supply their products directly into the bloodstream,
- manufacture hormones (biological chemicals that influence the operation of other organs and tissues),
- include the pituitary gland, pancreas, ovaries, testes, thyroid gland, and adrenal glands. The stomach also has endocrine activity,
- are critical to bodily functions. The thyroid creates thyroxin, which regulates the body's overall metabolic rate. Low thyroxin (hypothyroidism) means low energy consumption, lethargy and weight gain, for example. A faulty pancreas leads to low insulin levels, excessive/erratic blood sugar, and diabetes,
- differ from exocrine ("external") glands such as the liver, which supplies products into other body systems, such as bile into the digestive tract.
ENDOCRINE GLANDS ARE DUCTLESS
What is connection between endocrine system and urinary system?
The endocrine system (specifically pituitary gland and adrenal gland (cortex)) secrete hormones (ADH - antidiuretic hormone & aldosterone) which cause the kidneys to reabsorb salt. This, in turn, causes the kidneys to increase water re-absorption. All of this increases blood volume, which increases blood pressure.
Alternatively, ANH (Atrial Natriuretic Hormone) is secreted by the atrium of the heart. This causes the kidneys to reabsorb less sodium (and less water) which decreases blood volume and decreases blood pressure.
Epinephrine and Norepinephrine are released from the adrenal glands (medulla) during short-term stressful events, which increases blood pressure by vasoconstriction and slows digestion and bowel movements.
What are symptoms of Type I diabetes mellitus?
Is the biceps brachii or triceps brachii located on the anterior surface of the arm?
The triceps are located on the back of the arm. The quadriceps are located on the front of the thigh.
Why does polyuria occur with diabetes mellitus?
I think you mean polyuria instead of polyurea. Polyuria is a medical term used to describe the symptom of increased frequency of urination. When glucose levels in blood are greater than normal, the molecule of glucose 'leaks' into the urine. As glucose enters the urine, it brings water molecules with it and, in turn, urine volume increases and, 'voila', polyuria happens..
Which system are the adrenal glands a part of?
The adrenal glands are part of the endocrine system. This gland helps to control blood sugar. In addition, also helps your body by promoting proper cardiovascular function. properly utilizing carbohydrates and fats, helps to distribute stored fat and promotes healthy gastrointestinal functions. They also release a hormone that helps deal with stress called adrenaline.
