What does the thymus secrete to stimulate T lymphocytes?
Im afraid that your question is quite unclear.
If you are refering to how the thymus turns pre-T Cells into Naieve T-cells, this is not a process mediated by a secretion. Its a process called positive and negative selection (or central tollerance) mediated by surface molecules called MHCs present on thymic cells and Dendritic Cells, which eliminates those cells that either do not react with these MHCs or react too strongly. I hope this answers your question.............
Types of hormones and their function?
Primarily produced in your endocrine glands, hormones manage and control everything in your body. From your immune response to your energy output, it regulates your blood-sugar level, maintains the critical balance among your body's electrolytes, and enables you to build strong healthy bones, it determines how you mature and how slowly or quickly you age. Because of them, women are able to become pregnant and carry a baby. It helps you digest and assimilate your food, convert it into energy, and then use the energy to build muscles or burn fat. And remarkably, your endocrine system monitors not only what is going on inside you but also what's going on around you. It interprets what you see and experience and translates it into physical reactions in your body, enabling you to adapt to change and to cope with stresses of all kinds.
- Thyroid hormones: Insulin, Adrenaline, Calcitonin

At what age can you get diabetes mellitus?
I don't think there is a limit I was diagnosed with Type 1 (juvenile diabetes) at 26 yrs old, I was told its rare and its possible i have had it longer and not known(i was a heavy drinker) it could have masked some symptoms but when I did get sick I got really sick near death I was very lucky that I found out on time. best advice is to know the symptoms and be careful, I experienced drastic wieghtloss uncontrollable hunger and thirst(my body couldn't process food for energy) frequent urination, fruity breath, shakyness, fatigue, II was also very lethargic thinking (I'll be fine i just need to relax) I literally had family members come to my house and drag me to the ER, I was very lucky I was in DKA diabetic keto acidosis, I was in the hospitol on IV's for almost 2 weeks, best bet is to watch the symtpoms and inform yourself so that you can be careful its really a scarey experience but once controlled you can live a normal happy healthy life, I feel better and have more energy now then I have had in years.
What does it mean if a thyroid nodule is vascular?
There's blood supply inside of it not just leading to it
What are the thyroid and parathyroid glands?
There are several thyroid hormones, but the most frequently referenced are T4 and T3.
- T4 - thyroxine - is storage hormone. Its job is to circulate until it is needed. It will be converted by the body into T3 as needed by cells and organs.
- T3 - triiodothyronine - this is the hormone used by the body's cells. Some is produced by the thyroid, but most is converted by the body as needed from T4.
TSH is often considered a thyroid hormone, however it is not. It is produced by the pituitary gland and stimulates the thyroid to produce hormones.
What is the medical term meaning surgical removal of the pituitary gland?
Hypophysectomy
hypophysectomy
hypophysectomy
Hypophysectomy is surgical removal of the pituiatry, a gland in the brain.
Explain the structure of the adrenal glands?
If you are referring to the glands that are situated atop of each kidney, they are somewhat of a 3-sided, triangular based pyramid.
If you are referring to one of the other glands in the adrenal system, you must specify. Glad if I could be of help.
How do you know if you have thyroid problems?
These are the symptoms: fatigue, lethargy, constipation, weight gain, edema (water retention), headaches, decreased libido, depression, memory loss, and poor concentration, dry skin, thinning hair or loss of hair, hoarseness, feeling of lump in the throat, sensitivity to cold, insomnia, infertility, and severe menopausal symptoms. It is possible to confirm the diagnosis with a blood test.

Nearly twenty organs and tissues have been discovered in Mammals and Human which secrete hormones and comprise endocrine system . Most of organs included in list are exclusively endocrine in nature while some organs perform other functions but also produce some hormones .
Organs :
1 : Adenohypophysis ( Anterior Pituitary Gland ) is considered master gland , produces 7 hormones
2 : Neurohypophysis ( Posterior Pituitary Gland ) produces two hormones .
3 : Pars inter-media ( Median lobe ) produces one hormone .
4 : Hypothalamus is part of nervous system and also produces releasing and inhibiting hormones .

Why are the endocrine glands called ductless glands?
Because an endocrine glad does not have a tube through which it delivers hormone to the body. They just release their hormones into the space around the gland, which diffuse into the blood stream.
Characteristics of endocrine system?
One interesting fact is that the endocrine system has no ducts. Therefore, the hormones it produces are released directly into the bloodstream. The blood then carries it to the various parts.
Also, the endocrine system is responsible for producing 30 distinct hormones. All these hormones have very distinct jobs to do.
The rush of adrenaline one gets when facing adventure or fear is the result of the adrenal glands production of epinephrine hormone, or adrenaline as we otherwise know it.
We must be thankful to the pineal gland for our sweet sleep. It secretes melatonin which regulates our sleep.
It is responsible for the production of insulin. The failure to produce insulin will result in diabetes.
The endocrine is the secret behind your energy levels thanks to the thyroid glands. The thyroid glands also help in metabolism.
The hypothalamus is the one that makes you feel hunger and thirst. It also helps in body temperature.
It aids the immune system by helping the body build resistance to disease.
The human behavior is also controlled by the endocrine system when it affects the nervous system.
It is accountable for sexual characteristics and development. It is the key player in regulating menstrual cycle and ovulation in women. It even plays a role in pregnancy by stimulating contractions during delivery.
In fact, the endocrine system has a hand in almost all functions of the human body.
Describe at least two ways the skeletal system interacts with the other body systems?
skeletal system affects other body systems in many ways. such as it affects circulatory system because red blood marrow in bone bone makes blood
What are the functions of the endocrine system?
The endocrine system is one of the most important systems that govern the body. Acting with the nervous system, it helps coordinate and integrate the activity of the body's cells.
It consists the glands that produce the hormones.
The major functions of the endocrine system are:
~it regulates the metabolic functions of the body
~regulates the rate of chemical reactions in various cells
~influences the ability of substances to transport themselves through cell membranes
The endocrine system main function is to create and make work the glands.
The endocrine system produces chemicals that control many of the body's daily activities. The endocrine system also regulates long-term changes such as growth and development.
The thyroid is a gland situated in the neck area that secretes hormones. Thyroxin is a hormone that is released by the thyroid gland, along with iodothyronin and calcitonin.
Who invented Synthroid thyroid medicine?
Synthroid is currently manufactured by Abbott Laboratories but was originally isolated by Mayo Clinic. Currently there are generic products on the market that are made by various manufacturers as well
Why are there different hormones in men and women?
because they need different for different parts of a male and female's body.
Adrenaline and noradrenaline hormones are secreted in stress conditions. During this the blood vessels dilates and the heart rate increases. BUT actually the function of both the hormone is synergistic in raising the blood pressure. These also release glucose from liver and reinforce the effects of sympathetic system. In the absence of these hormones, the stress conditions are diminished.
List the cardinal symptoms of diabetes mellitus?
Diabetes Mellitus comes in two common forms, Insulin-Dependent Diabetes Mellitus (or Type 1 Diabetes) and Non-Insulin-Dependent Diabetes Mellitues (Type 2 Diabetes). (There is also Gestational Diabetes which occurs during pregnancy).
Type 1 diabetes is an autoimmune disease mainly found in children. In this type of diabetes the child's immune system attacks insulin producing cells found in the pancreas. Insulin is a hormone that raises blood sugar.
Type 2 diabetes is due to diet and age. This form of diabetes is traditionally found in older individuals, but we often hear about the rise of diabetes in younger people. In this case the body is worn down and organs, especially the pancreas and liver, are not able to regulate blood sugar as effectively.
The symptoms of both forms of diabetes are the same. The person will experience excessive thirst and hunger, weight loss, frequent urination, and fatigue. The excessive thirst is due to dehydration. The blood glucose (sugar) is increased and the individual will have a high amount of glucose in their urine (giving it a sweet smell) causing them to loose more water. Glucose in the urine can also cause more bladder infections. Due to the high amounts of blood sugar they may experience blurry vision and lethargy.
Where is thyroid stimulating hormone TSH synthesized?
it is produced in the anterior pituitary gland, which stimulates the release of thyroxine form the thyroid gland
What does the endocrine system release in the blood stream?
Endocrine glands release hormones. These chemical messengers control body processes.
