| theca cell tumour | A sex cord-stromal tumour of the postmenopausal ovary that is yellow, large, and unilateral, composed of fascicles of lipid-rich spindle cells interspersed with collagen, reticulin fibres, and hyaline plaques. Thecomas and other oestrogen-producing tumours (e.g., granulosa cell tumours) may induce adenomatous hyperplasia of the endometrium or well-differentiated endometrial carcinoma in 3%-20% of the cases. (12 Dec 1998) |
| theca cells | The connective tissue cells of the graafian follicle. (12 Dec 1998) |
| theca cells of stomach | Cell's lining the gastric surface and foveolae; a glycoprotein product at the apical end of each cell is secreted and forms a mucous protective film. Synonym: theca cells of stomach. (05 Mar 2000) |
| theca cordis | <anatomy> A double membranous sac which envelops and protects the heart. The layer in contact with the heart is referred to as the visceral layer, the outer layer in contact with surrounding organs is the parietal pericardium. In between the two layers is the pericardial space. (27 Sep 1997) |
| theca externa | <embryology> The external fibrous layer of the theca of a well-developed vesicular ovarian follicle; the cells and fibres are arranged in a concentric fashion. Synonym: theca externa. (05 Mar 2000) |
| theca folliculi | The wall of a vesicular ovarian follicle. See: tunica externa, tunica interna thecae folliculi. (05 Mar 2000) |
| theca interna | <embryology> The inner cellular and vascular layer of the vesicular ovarian follicle. There is evidence that the epithelioid cells produce oestrogen and contribute to the formation of the corpus luteum after ovulation. Synonym: theca interna. (05 Mar 2000) |
| theca interna cone | The conical thickening of thecal cells of an ovarian follicle with its apex pointed toward the surface. (05 Mar 2000) |
| theca lutein cell | A steroid secretory cell of the corpus luteum that comes from the theca interna of the ovarian follicle at the time of ovulation. Synonym: paraluteal cell, paralutein cell. (05 Mar 2000) |
| theca tendinis | A sheath of synovial membrane enveloping certain of the tendons; it contains a small amount of synovial fluid. Synonym: vagina synovialis tendinis, mucous sheath of tendon, theca tendinis, vagina mucosa tendinis, vaginal synovial membrane. (05 Mar 2000) |
| theca vertebralis | Single-layered strong membrane, comparable to and continuous with (at foramen magnum) the meningeal layer of the intracranial dura mater of the brain. It does not (in contrast to the dura mater of brain) adhere to the enveloping bony structures (vertebrae) or their periosteum, being separated from the latter by a considerable space, the vertebral epidural space-a true space containing the internal vertebral venous plexus embedded in a matrix of epidural fat. Synonym: dura mater spinalis, endorrhachis, theca vertebralis. (05 Mar 2000) |
| thecal | Relating to a sheath, especially a tendon sheath. Origin: see theca (05 Mar 2000) |
| thecal abscess | Suppuration in a sheath or capsule. (05 Mar 2000) |
| thecal whitlow | Suppurative lesion of distal phalanx; may involve tendon sheath and bone. (05 Mar 2000) |
| ovarian granulosa-theca cell tumour | <radiology> Any age, most benign, oestrogens may lead to isosexual precocious puberty (pathognomonic), large tumour with areas of cystic degeneration (12 Dec 1998) |
