Recipes starting with T

T3

Triiodothyroninine. The active metabolite of thyroxine.

T4 is converted to T3. T3 is also produced by the thyroid gland.

T4

Thyroxine.

The principal product of thyrod secretion.

Testosterone

The main male sex hormone.

Testosterone production is encouraged by LH from the pituitary gland; small amounts also present in women.

Triglycerides are a type of fat in the bloodstream and fat tissue. Too much of this type of fat can contribute to the hardening and narrowing of your arteries, increasing the risk of heart attack or stroke. High triglycerides can be caused by diabetes, obesity, kidney failure or alcoholism. Often, high triglycerides occur along with high levels of cholesterol. Triglyceride and cholesterol levels are measured as part of a blood test. Normal triglyceride levels are below 150. Levels above 200 are high.

Therapeutic Radiology

A medical specialty and the study of radiation treatment of abnormal tissue (nonmalignant or cancerous) through the use of x-rays or radionuclides.

See radiotherapy.

Therapist

One professionally trained and/or skilled in the practice of a particular type of therapy.

Thyroid Gland

A ductless gland, consisting of irregularly spheroidal follicles, lying in front and to the sides of the upper part of the trachea, and of horseshoe shape, with two lateral lobes connected by a narrow central portion, the isthmus; occasionally an elongated offshoot, the pyramidal lobe, passes upward from the isthmus in front of the trachea. It is supplied by branches from the external carotid and subclavian arteries, and its nerves are derived from the middle cervical and cervicothoracic ganglia of the sympathetic system. It secretes thyroid hormone and calcitonin.

1) A gland located beneath the voice box (larynx) that produces thyroid hormone. The thyroid helps regulate growth and metabolism. Underactive thyroid is also called hypothyroidism. This is a condition in which the thyroid gland doesn't make enough thyroid hormone. Lack of thyroid hormone will slow down your metabolism and cause weight gain.
2) The endocrine gland normally situated in the lower part of the front of the neck; secretes, stores and releases the iodine dependent thyroid hormones thyroxine and triiodothyroine which play major endocrine roles in regulating metabolic rate; also secretes thyrocalcitonin.

Tissue

A group of similar cells united to perform a specific function.

TNF

Tumor necrosis factor.

A protein made by white blood cells in response to an antigen (substance that causes the immune system to make a specific immune response) or infection. Tumor necrosis factor can also be made in the laboratory. It may boost a person's immune response, and also may cause necrosis (cell death) of some types of tumor cells. Tumor necrosis factor is being studied in the treatment of some types of cancer. It is a type of cytokine.

Tomography

Making a radiographic image of a selected plane by means of reciprocal linear or curved motion of the x-ray tube and film cassette; images of all other planes are blurred ("out of focus") by being relatively displaced on the film.

Computed tomography (CT) is a diagnostic procedure that uses special x-ray equipment to obtain cross-sectional pictures of the body. The CT computer displays these pictures as detailed images of organs, bones, and other tissues. This procedure is also called CT scanning, computerized tomography, or computerized axial tomography (CAT).
