| thyrocardiac disease | Heart disease resulting from hyperthyroidism. (05 Mar 2000) |

| thyrocervical | Relating to the thyroid gland and the neck, denoting an arterial trunk. (05 Mar 2000) |
| thyrocervical trunk | A short arterial trunk arising from the subclavian artery, giving rise to the suprascapular (which may instead arise directly from the subclavian artery) and terminating by dividing into the ascending cervical and inferior thyroid arteries. Synonym: truncus thyrocervicalis, thyroid axis. (05 Mar 2000) |
| thyrocolloid | A colloid substance in the thyroid gland. (05 Mar 2000) |
| thyroepiglottic | Relating to the thyroid cartilage and the epiglottis. (05 Mar 2000) |
| thyroepiglottic ligament | <anatomy> Thyroepiglottidean ligament, an elastic band that connects the petiole of the epiglottis to the interior of the thyroid cartilage near the superior thyroid notch. Synonym: ligamentum thyroepiglotticum. (05 Mar 2000) |
| thyroepiglottic muscle | <anatomy, muscle> Origin, inner surface of thyroid cartilage in common with musculus thyroarytenoideus; insertion, aryepiglottic fold and margin of epiglottis; action, depresses base of epiglottis; nerve supply, recurrent laryngeal. Synonym: musculus thyroepiglotticus, depressor muscle of epiglottis, ventricularis. (05 Mar 2000) |
| thyrofissure | Operative opening into the larynx, generally through the midline, commonly done for the excision of early carcinoma or the correction of laryngostenosis. Synonym: median laryngotomy, thyrofissure, thyroidotomy, thyrotomy. (05 Mar 2000) |

| thyroglobulin | <biochemistry> The 650 kD protein of the thyroid gland that binds thyroxine. (18 Nov 1997) |
| thyroglobulin antibody | <investigation> A serologic blood test which measures the antithyroglobulin antibodies in the blood. Thyroglobulin is a protein found in thyroid tissue. It is the source of thyroid hormones in the body. The presence of antibodies to this protein can result in decreased thyroid gland function. A negative assay is considered normal. Conditions where the assay may be positive include: lupus, rheumatoid arthritis, Hashimoto's thyroiditis, thyrotoxicosis, hypothyroidism, thyroid cancer, myxoedema, Sjogren's syndrome and autoimmune haemolytic anaemia.
