| thyroid ima artery | <anatomy, artery> An inconstant artery; origin, arch of aorta or brachiocephalic artery; distribution, thyroid gland. Synonym: arteria thyroidea ima, lowest thyroid artery, Neubauer's artery. (05 Mar 2000) |
|---|---|
| thyroid imaging | <radiology> Tc-99m pertechnetate 6 mCi, I-123 sodium iodide 200 - 400 uCi PO (12 Dec 1998) |
| thyroid insufficiency | Subnormal secretion of hormones by the thyroid gland. See: hypothyroidism. (05 Mar 2000) |
| thyroid lymph nodes | Nodes of the anterior deep cervical group located around the thyroid gland; they drain into the lateral deep cervical group. Synonym: nodi lymphatici thyroidei. (05 Mar 2000) |
| thyroid nodule | A small circumscribed mass of differentiated tissue associated with the thyroid gland. It can be pathogenic or non-pathogenic. The growth of nodules can lead to a condition of goiter, nodular. most nodules appear between the ages of 30 and 50 years and most are benign. (12 Dec 1998) |
| thyroid releasing hormone | <endocrinology> Thyroid releasing hormone (TRH) is a byproduct of the hypothalamus and serves to stimulate the pituitary gland to produce thyroid stimulating hormone (TSH). TRH is produced by the hypothalamus when thyroid hormone (T3 and T4) blood levels are low. (27 Sep 1997) |
| thyroid scan | A picture taken of the thyroid gland after radioactive iodine is taken by mouth. (12 Dec 1998) |
| thyroid storm | A severe form of hyperthyroidism caused by excessive quantities of thyroid hormones. Thyrotoxicosis may occur as a complication of Grave's disease. Symptoms include weight loss, increased appetite, restlessness, heat intolerance, increased sweating, sleep difficulty, muscle cramps, fatigue, diarrhoea, thirst, muscle atrophy, bounding pulse, tremor, protruding eyes (exophthalmos), high blood pressure and menstrual irregularities. Death can result from congestive heart failure and pulmonary oedema. May be associated with goitre. (27 Sep 1997) |
| thyroid suppression test | A thyroid function test used to diagnose difficult cases of hyperthyroidism, now largely replaced by the thyrotropin-releasing hormone stimulation test; triiodothyronine is administered for a week to 10 days, and a reduction of its uptake by the thyroid gland to less than half of the initial uptake is a normal response. Synonym: Werner's test. (05 Mar 2000) |
| thyroid therapy | The treatment of hypothyroidism. (05 Mar 2000) |
| thyroid toxicosis | Hyperthyroidism resulting from excessive circulating 3,5,3'-triiodothyronine. Synonym: thyroid toxicosis. (05 Mar 2000) |
| thyroid veins | See: inferior thyroid vein, middle thyroid vein, superior thyroid vein, plexus thyroideus impar. (05 Mar 2000) |
| elevator muscle of thyroid gland | A fasciculus occasionally passing from the thyrohyoid muscle to the isthmus of the thyroid gland. Synonym: musculus levator glandulae thyroideae, elevator muscle of thyroid gland, Soemmerring's muscle. (05 Mar 2000) |
| fibrous capsule of thyroid gland | The fibrous sheath of the thyroid gland. Synonym: capsula fibrosa glandulae thyroideae. (05 Mar 2000) |
| follicles of thyroid gland | <physiology> The small spherical vesicular components of the thyroid gland lined with epithelium and containing colloid in varying amounts. The colloid serves for storage of the thyroid hormone precursor, thyroglobulin. Synonym: follicles of thyroid gland. Origin: L. A small sac, dim. Of follis, bellows (05 Mar 2000) |
