| superior thyroid plexus | An autonomic plexus on the artery of the same name, derived from the external carotid plexus. Synonym: plexus thyroideus superior. (05 Mar 2000) |
|---|---|
| superior thyroid tubercle | A blunt projection on the lamina of the thyroid cartilage on either side at the superior end of the oblique line. Synonym: tuberculum thyroideum superius. (05 Mar 2000) |
| superior thyroid vein | <anatomy, vein> Receives blood from the upper part of the thyroid gland and larynx, accompanies the artery of the same name, and empties into the internal jugular vein. Synonym: vena thyroidea superior. (05 Mar 2000) |
| suspensory ligament of thyroid gland | One of several fibrous bands which pass from the sheath of the thyroid gland to the thyroid and cricoid cartilages. (05 Mar 2000) |
| discordant thyroid nodule | <radiology> Hot on Tc-99m pertechnetate, cold on I-123 or I-131, indicates trapping, but no organification, same work-up as cold nodule (12 Dec 1998) |
| immunoglobulins, thyroid-stimulating | Autoantibodies that bind to the thyroid-stimulating hormone (tsh) receptor (receptors, thyrotropin) on thyroid epithelial cells. The autoantibodies mimic tsh causing an unregulated production of thyroid hormones characteristic of graves' disease. (12 Dec 1998) |
| inferior horn of thyroid cartilage | One of the pair of downward prolongations at the back of the thyroid cartilage; it articulates on each side with the cricoid cartilage. Synonym: cornu inferius cartilaginis thyroideae. (05 Mar 2000) |
| inferior thyroid notch | A shallow notch in the middle of the lower border of the thyroid cartilage. Synonym: incisura thyroidea inferior. (05 Mar 2000) |
| inferior thyroid plexus | An autonomic plexus on the artery of this name, derived from the subclavian plexus. Synonym: plexus thyroideus inferior. (05 Mar 2000) |
| inferior thyroid tubercle | A slight lateral projection from the lower margin of the lamina of the thyroid cartilage on either side, at the inferior end of the oblique line. Synonym: tuberculum thyroideum inferius. (05 Mar 2000) |
| inferior thyroid vein | <anatomy, vein> Unpaired vein formed by veins from the isthmus and lateral lobe of the thyroid gland and from the plexus thyroideus impar; it terminates in the left brachiocephalic vein. Synonym: vena thyroidea inferior, vena thyroidea ima. (05 Mar 2000) |
| isthmus of thyroid | The central part of the thyroid gland joining the two lateral lobes. Synonym: isthmus glandulae thyroideae. (05 Mar 2000) |
| oblique line of thyroid cartilage | A ridge on the outer surface of the thyroid cartilage that gives attachment to the sternothyroid and thyrohyoid muscles. Synonym: linea obliqua cartilaginis thyroidea. (05 Mar 2000) |
| ectopic thyroid | <radiology> Usually connects to normal thyroid, sites: lingual thyroid, thyroglossal duct remnant, anterior mediastinum (retrosternal thyroid), btw trachea and oesophagus, struma ovarii (teratoma variant), use pertechnetate first (rather than I-131) because of lower dose (12 Dec 1998) |
| thyroid | A butterfly-shaped endocrine gland in the neck that is found on both sides of the trachea (windpipe). It secretes the hormone thyroxine which controls the rate of metabolism. (27 Sep 1997) |
