2 The Thyroid and Disruption of Thyroid Function in Humans

function of thyroid gland pdf

Hyperthyroidism (overactive thyroid gland). Thyroid function tests are blood tests which help to check the function of your thyroid gland. They are mainly used to detect an underactive thyroid gland (hypothyroidism) and an overactive thyroid gland (hyperthyroidism). Lots of basic information about the thyroid gland can be found in the, Thyroid disorders can be difficult to detect clinically, but thyroid function tests can assist in making a diagnosis. Measuring thyroid stimulating hormone is the first step. If it is abnormal, free thyroxine should be measured. A raised concentration of thyroid stimulating hormone with a low concentration of free thyroxine suggests hypothyroidism. A low concentration of thyroid stimulating.

IMPORTANCE OF SELENOPROTEINS FOR THE FUNCTION OF THE. The active thyroid gland has small follicles with lining is cuboidal or columnar lining , scanty colloid and scalloped edges forming reabsorption lacunae. The follicular cells have several functions including the collection and transport iodine to colloid,, 4 Thyroid Gland (Tetrapods) • Thyroid hormones (TH) – Thyroxine (T4) and triiodothyronine (T3) • Increase metabolic rate and body heat production.

The thyroid gland is a downgrowth from the pharyngeal endoderm of the developing tongue. The calcitonin producing cells are different and are derived from the fourth branchial pouch. Anatomy.

The thyroid is a small, butterfly-shaped gland in the front of your neck that makes two thyroid hormones: thyroxine (T 4) and triiodothyronine (T 3). Thyroid hormones control how the body uses energy, so they affect nearly every organ in your body, even your heart. The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine.

    Thyrotropin (thyroid-stimulating hormone, TSH) is produced by the anterior pituitary gland that stimulates all aspects of thyroid function, including the production of symporter molecules and therefore iodide transport. Lithium interferes with thyroid hormone synthesis and inhibits their release from the gland. Long term lithium treatment results in goitre in up to 50% of patients, subclinical hypothyroidism occurs in 20% and overt hypo-thyroidism in a further 20%. The presence of thyroid peroxidase antibodies may be useful to predict the future development of hypothyroidism in long- term treated patients.

    As a result, interpretation of thyroid function tests is now generally straightforward, and more than 90% of people investigated are diagnosed with normal thyroid gland function. However, there remain a few situations in which the results of TSH, free T4, and free T3 assays tend to point in different directions, as well as cases in whom thyroid function test results seem clear cut but are in dealing with their target glands: hormonal control of the thyroid, parathyroid and adrenal glands is discussed in Chapter 16, hormo - nal control of the reproductive system is discussed in Chapters 33
