| ovarian follicle | <biology, gynaecology> In mammals the group of cells around the primary oocyte proliferate and form a surrounding noncellular layer. A space opens up in the follicle cells and the whole structure is then the ovarian Graafian) follicle. (05 Jan 1998) |
|---|---|
| follicle | 1. <anatomy> Generally a small sac or vesicle. 2. <botany> A kind of fruit formed from a single carpel, that splits to release its seeds. 3. <dermatology> A hair follicle, an invagination of the epidermis into the dermis surrounding the hair root. 4. <gynaecology, physiology> An ovarian follicle, an oocyte surrounded by one or more layers of granulosa cells. As the ovarian follicle develops a cavity forms and it is then termed a Graafian follicle. (12 Nov 1997) |
| follicle cell | <gynaecology, pathology> A layer of cells within an ovarian follicle which surrounds the oocyte (proto-ovum) and provides certain nutrients to it. (09 Oct 1997) |
| follicle-stimulating hormone | <hormone> An acidic glycoprotein secreted by the anterior pituitary gland. In women, follicle-stimulating hormone stimulates the development of ovarian follicles (eggs) and stimulates the release of oestrogens. In men, follicle-stimulating hormone stimulates the production of sperm. Abnormal follicle-stimulating hormone levels may be seen in the following conditions: hypopituitarism, Klinefelter syndrome, polycystic ovary disease, Turner's syndrome and ovarian failure. Synonym: follitropin. Acronym: FSH (12 Sep 2002) |
| follicle-stimulating hormone-releasing factor | A decapeptide of hypothalamic origin capable of accelerating pituitary secretion of follitropin. Synonym: follicle-stimulating hormone-releasing factor, follicle-stimulating hormone-releasing hormone. Origin: follicle-stimulating hormone + L. Libero, to free, + -in (05 Mar 2000) |
| follicle-stimulating hormone-releasing hormone | A decapeptide of hypothalamic origin capable of accelerating pituitary secretion of follitropin. Synonym: follicle-stimulating hormone-releasing factor, follicle-stimulating hormone-releasing hormone. Origin: follicle-stimulating hormone + L. Libero, to free, + -in (05 Mar 2000) |
| luteinised unruptured follicle syndrome | <syndrome> The failure of a follicle to release the egg even though a corpus luteum has formed. (09 Oct 1997) |
| luteinizing hormone/follicle-stimulating hormone-releasing factor | gonadotrophin-releasing hormone |
| accessory nerve lymph nodes | The nodes of the lateral deep cervical group that are located along the accessory nerve; their efferent vessels pass to the supraclavicular lymph nodes. Synonym: companion lymph nodes of accessory nerve, nodi lymphatici comitantes nervi accessorii. (05 Mar 2000) |
| angiofollicular mediastinal lymph node hyperplasia | Solitary masses of lymphoid tissue containing concentric perivascular aggregates of lymphocytes, occurring usually in the mediastinum or hilar region of young adults; similar changes have been reported outside the mediastinum and, if associated with interfollicular sheets of plasma cells, may progress to lymphoma or plasmacytoma. Synonym: angiofollicular mediastinal lymph node hyperplasia, Castleman's disease. (05 Mar 2000) |
| anorectal lymph nodes | Nodes located on either side of the rectum; they send efferents to the middle rectal and superior rectal nodes. Synonym: nodi lymphatici pararectales, nodi lymphatici anorectales, anorectal lymph nodes. (05 Mar 2000) |
| anterior cervical lymph nodes | The group of lymph nodes located in the anterior region of the neck, divided into superficial and deep groups. Synonym: nodi lymphatici cervicales anteriores. (05 Mar 2000) |
| anterior deep cervical lymph nodes | The lymph nodes near the larynx, trachea, and thyroid gland. Synonym: nodi lymphatici cervicales anteriores profundi. (05 Mar 2000) |
| anterior group of axillary lymph nodes | Lymph nodes located along the lateral thoracic vein; they receive the drainage of the pectoral region, including most of the drainage of the breast. Synonym: nodi lymphatici axillaris pectorales, anterior group of axillary lymph nodes. (05 Mar 2000) |
| anterior jugular lymph nodes | Nodes of the lateral deep cervical group located anterior to the internal jugular vein; two nodes are specifically named: the jugulodigastric lymph node and the jugulo-omohyoid lymph node. Synonym: nodi lymphatici jugulares anteriores. (05 Mar 2000) |
