In normal conditions, the dew point temperature will not be greater than the air temperature, since relative humidity typically [5] does not exceed 100%. [ 6 ] In technical terms, the dew point is the temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same rate at which it ...
A medical sign is an objective observable indication of a disease, injury, or medical condition that may be detected during a physical examination. [4] These signs may be visible, such as a rash or bruise, or otherwise detectable such as by using a stethoscope or taking blood pressure. Medical signs, along with symptoms, help in forming a ...
The main diagnostic sign is an oral body temperature that averages well below 37.0 °C (98.6 °F). This overlaps with normal body temperature, which is usually within the range of 36.5–37.5 °C (97.7–99.5 °F). [5] [6] Wilson says that his diagnosis is confirmed if the patient responds to treatment with slow-release T3 (SR-T3).
Hypothyroidism (also called underactive thyroid, low thyroid or hypothyreosis) is a disorder of the endocrine system in which the thyroid gland does not produce enough thyroid hormones. [3] It can cause a number of symptoms, such as poor ability to tolerate cold , extreme fatigue, muscle aches , constipation , slow heart rate , depression , and ...
Reverse T 3 is the third-most common iodothyronine the thyroid gland releases into the bloodstream, at 0.9%; tetraiodothyronine (levothyroxine, T 4) constitutes 90% and T 3 is 9%. However, 95% of rT 3 in human blood is made elsewhere in the body, as enzymes remove a particular iodine atom from T 4 .

Thyroid follicular cells form a simple cuboidal epithelium and are arranged in spherical thyroid follicles surrounding a fluid filled space known as the colloid. The interior space formed by the follicular cells is known as the follicular lumen .
The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans, it is in the neck and consists of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the isthmus (pl.: isthmi). The thyroid gland is a butterfly-shaped gland located in the neck below the Adam's apple.
