|---|---|
| FRH | follicle-stimulating hormone-releasing hormone |
| FRP | follicle-stimulating hormone releasing protein; functional refractory period |
| FSH | fascioscapulohumeral; focal and segmental hyalinosis; follicle-stimulating hormone |
| FSHB | follicle-stimulating hormone, beta chain |
| primordial ovarian follicle | A follicle in which the primordial oocyte is surrounded by a single layer of flattened follicular cells. (05 Mar 2000) |
|---|---|
| secondary follicle | A follicle in which the oocyte attains its full size and is surrounded by an extracellular glycoprotein layer (zona pellucida) that separates it from a peripheral layer of follicular cells permeated by one or more fluid-filled antra; the theca of the follicle develops into internal and external layers. Synonym: folliculus ovaricus vesiculosus, graafian follicle, secondary follicle. (05 Mar 2000) |
| nabothian follicle | <radiology> Chronic cervicitis most likely to be inflammatory stenosis of cervical glands most likely to be retention most likely to be cyst Differential diagnosis: cystic mass of cervix, ectopic pregnancy, adenomyosis (12 Dec 1998) |
| neck of hair follicle | The narrowed part of the hair follicle between the hair bulb and the surface of the skin. Synonym: collum folliculi pili. (05 Mar 2000) |
| dental follicle | <dentistry> The dental sac with its enclosed odontogenic organ and developing tooth. (05 Mar 2000) |
| 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 |
| lymph follicle | Lymphatic follicle, one of the spherical masses of lymphoid cells, frequently having a more lightly staining centre. See: solitary lymphatic follicles, Peyer's patches. Synonym: folliculus lymphaticus, lymph nodule, nodulus lymphaticus. (05 Mar 2000) |
