4. Thyroid gland definition
The thyroid gland, or simply the thyroid, is an endocrine gland in the neck, consisting of two lobes connected by an isthmus. It is found at the front of the neck, below the Adam's apple. The thyroid gland secretes thyroid hormones, which primarily influence the metabolic rate and protein synthesis.

The primary function of your thyroid gland is to secrete thyroid hormones. The thyroid hormones are involved in regulating many of your bodily functions, such as your breathing, heart rate, temperature, how quickly you burn calories, and digestion, among other functions.

11. Thyroid gland hormones
: The 2 main thyroid hormones are T3 (triiodothyronine) T4 (thyroxine). T3 and T4 regulate body's temperature, metabolism and heart rate.

12. T3 or triiodothyronine
T3 tests can help diagnose an overactive thyroid (hyperthyroidism). The usual accepted normal range for free T3 (which measures T3 in the bloodstream, but not T3 bound to protein in your body) is between 3.1 pmol/L and 6.8 pmol/L

13. T4 (thyroxine)
The normal range usually quoted for free thyroxine (T4) is pmol/L. In people with hyperthyroidism (overactive thyroid), free T4 is usually above 22 pmol/L. And for those with hypothyroidism (underactive thyroid), free T4 is usually below 12 pmol/L.

There are specific kinds of thyroid disorders that includes:
1.Hypothyroidism
2.Hyperthyroidism
3.Thyroid cancer

17. 1.Hypothyroidism
Hypothyroidism refers to any state in which a person's thyroid hormone production is below normal.
There are many disorders that result in hypothyroidism, for example, autoimmune disorders, thyroid removal, prescription medications, pituitary disease, and iodine deficiency.
Hypothyroidism is a very common condition.

18. 1.Hypothyroidism The symptoms of hypothyroidism include :
Increased cholesterol levels
Depression
Fatigue
Hair loss
Memory loss
Dry rough skin
Constipation.

19. 2.Hyperthyroidism
Hyperthyroidism is a condition in which there is an excessive amount of thyroid hormones.
Normally, the rate of thyroid hormone production is controlled by the brain from the pituitary gland, which is in turn regulated by the hypothalamus.
Graves' disease, the most common cause of hyperthyroidism, can be associated with eye disease (Graves' opthalmopathy)

20. 2.Hyperthyroidism Common symptoms of hyperthyroidism include:
Restlessness
Agitation
Anxiety
Tremors
Weight loss 
Sweating
Rapid heart rate

21. 3.Thyroid cancer
Thyroid cancer is three times more common in women than in men.
The cause of thyroid cancer is unknown, but certain risk factors have been identified and include a family history of goiter and exposure to high levels of radiation

22. 3.Thyroid cancer
The most common signs and symptoms of :thyroid cancer include
A lump or thyroid nodule
