Cold nodule in thyroid

1:Thyroid cancer.
Thyroid cancer is a condition when a tumor forms on the Thyroid gland, a small organ located in the throat. Although as much as 75% of the population will have thyroid nodules, the vast majority are benign. Young people usually don't have thyroid nodules, but as people age, they likely develop a nodule. By the time we are 80, 90% of us will have at least one nodule. Thankfully, though, far less than 1% of all thyroid nodules are malignant. A nodule that is cold on scan, such as the one in the image, is more likely to be malignant. Neverthe less, most thyroid tumors are hardly harmful.

Diabetes is a disorder characterized by hyperglycemia or elevated blood glucose (blood sugar). Our bodies function best at a certain level of sugar in the bloodstream. If the amount of sugar in our blood runs too high or too low, then we typically feel bad. This is the most Common endocrine disorder. Their are two types of diabetes, cleverly name Type 1 and type 2 diabetes. Type 1 is insulin deficiancy where there is not enough insulin and the body is weak. The other type, Type 2,is when there is plenty of insulin made by the pancreas (it is functioning normally and making plenty of insulin), but the cells of the body are resistant to its action which results in the blood sugar being too high.


Osteoperosis is a condition caused by genes where bones become much denser (have more mass) and, consequently are considerably weaker than they should be due to a lack of calcium. There is no cure for this condition as it is simly a gene that causes the body to lose calcium. Though sometimes it can be prevented through mass consuption of calcium.

4:Pancriatic cancer.

Pancriatic cancer is when a tumor forms on your pancreas and slows or stops bile production. Bile is required to filter food and obtain nutrients. Also, due to the position of the tumor, in the abdomen between the stomach and intestines, it is extremly painful. Unfortunatly there is no, true cure. Infact, only about 20% of patients can have the tumor succesfully removed and live.

Major Endocrine organs:

adrenal glands
are a pair of glands that secrete hormones directly into the bloodstreem.outer region secrets hormones
in a way that energy is stored and food is used.

ovaries are a pair oval or almond -shaped glands which lie on eather side of the uterus , it produces eggs and it also produces a female hormone called estrogen.

pancreas- it is a long temperd gland which lies across ans behind the stomach, brakes down fats, and secretes digestive juices.

pituitary gland- is located in the center of the skull just behind the bridge of the nose, its the size of a pea, and its an important link between the nervous system and endocrine system. It also releases many hormones which effect the growth and sexual development.

Testes- hangs below the penis, there's a tissue that surounds them and the tissue contains muscle and contains spermendocrinebig.gif

Thymus- in upper part of the chest part of the immune system, consists of pockets blood cells

Thyroid- gland pea shaped, produces prominence on the neck "adams apple", CONTROLS RATE THAT BODY PRODUCES ENERGY FROM NUTRIENTS, CONTROLS LEVEL OF CALCIOUM IN BLOOD.

It influences almost every cell, organ and function in our bodies. Instrumental in mood, growth, development and tissue function is in charge metablism function of body processes, hormones and glands. It signal system is much like the nervous system.

In general the endocrine system is in charge of body processes that happen slowly, such as cell growth. Faster processes such as breathing are controlled by the nervous system, although they are different systems they are alike in many ways. The foundations of the endocrine system are glands and hormones, the bodies chemical messangers.

The major parts that make up the endocrine systems are
pineal body
the reproductive glands

Although the endocrine glands are the body's main hormone producers, some non-endocrine organs such as the brain, heart, lungs, kidneys, liver, thymus, skin, and placenta also produce and release hormones.

Once a hormone is secreted, it travels from the endocrine gland to the bloodstream to cells that are designed to receive its message. The special cells act as carriers that control the amount of hormone that is available to interact with and affect the target cells.

What other systems does
the endocrine system work with to
maintain homeostasis,

external image human-nervous-system.png
One other body system that helps the endocrine system maintain homeostasis is the nervous sytem which works with the pituritary gland. It does this by transferring signals from the brain to the endocrine system to help them carry out their processes such as releasing sexual and growth hromones. Another system that is linked with the endocrine system is the digestive system. This is shown through the pancreas. The pancreas secrets bile which helps aid in breaking down food and extracting nutrients.
