| 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) |
| follicular cancer of the thyroid | <oncology, tumour> A cancer of the thyroid gland that occurs with increased frequency in those who have had radiation exposure to the neck. Other risk factors include a family history of thyroid disease and history for goitre. Follicular carcinoma constitutes about 30% of all thyroid cancers. It has a greater rate of recurrence and metastasis than that of papillary carcinoma (the most common form of thyroid cancer). Symptoms include enlargement of the thyroid gland or neck swelling, change in voice, cough (occasionally bloody) and diarrhoea. (12 Nov 1997) |
| lamina of thyroid cartilage | One of the paired (dextra et sinistra) thin quadrilateral plates of the thyroid cartilage that are joined anteriorly and form an open angle posteriorly. Synonym: lamina cartilaginis thyroideae. (05 Mar 2000) |
| lateral aberrant thyroid carcinoma | <tumour> A cervical nodule of thyroid carcinoma situated outside the thyroid gland, formerly thought to arise from ectopic thyroid tissue but now believed to be metastatic from an occult carcinoma within the gland. (05 Mar 2000) |
| levator 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) |
| light cells of thyroid | Cell's present between follicles or interspersed among follicular cell's; they are rich in mitochondria and are believed to be the source of thyrocalcitonin. Synonym: C cell, light cells of thyroid. (05 Mar 2000) |
| lobes of thyroid gland | The two major divisions of the gland lying on the right and left side of the trachea and connected by the isthmus. A smaller pyramidal lobe is frequently present as an upward extension from the isthmus. Synonym: lobi glandulae thyroideae. (05 Mar 2000) |
| lobules of thyroid gland | The subdivisions of the lobes, consisting of incompletely separated, irregular groups of thyroid follicles (20 to 40 in number) bound together by delicate connective tissue. Synonym: lobuli glandulae thyroideae. (05 Mar 2000) |
| long-acting thyroid stimulator | <endocrinology, immunology> A thyroid stimulating antibody which is directed against a receptor for TSH on the thyroid gland. This antibody acts like TSH and stimulates the thyroid to produce excessive amounts of thyroid hormone. The presence of this antibody generally indicates Grave's disease (hyperthyroidism). Acronym: LATS (15 Nov 1997) |
| aditus glottidis inferior | The part of the cavity of the larynx immediately below the glottis. Synonym: cavitas infraglotticum, aditus glottidis inferior, cavum infraglotticum, inferior laryngeal cavity, infraglottic space. (05 Mar 2000) |
| angulus inferior scapulae | The acute angle formed by junction of the medial and lateral borders of the scapula. Synonym: angulus inferior scapulae. (05 Mar 2000) |
| anterior inferior iliac spine | Spine on the anterior border of the ilium between the anterior superior iliac spine and the acetabulum; site of origin for the direct head of the rectus femoris muscle. Synonym: spina iliaca anterior inferior. (05 Mar 2000) |
| anterior inferior segment | Anterior inferior segment of kidney. Synonym: segmentum anterius inferius. (05 Mar 2000) |
