|---|---|
| FRP | follicle-stimulating hormone releasing protein; functional refractory period |

| mature ovarian follicle | A follicle ready for ovulation; in the human ovary its antrum attains a diameter of 6 to 8 mm and presents a surface bulge; a first maturation (meiotic) division of the ovum usually occurs just prior to the rupture of the follicle. (05 Mar 2000) |
|---|---|
| Graafian follicle | <gynaecology> Final stage in the differentiation of follicles in the mammalian ovary. Consists of a spherical fluid filled blister on the surface of the ovary that bursts at ovulation to release the oocyte. (18 Nov 1997) |
| granular layer of a vesicular ovarian follicle | The layer of small cells that forms the wall of an ovarian follicle. Synonym: granular layer of a vesicular ovarian follicle, granulosa, membrana granulosa, stratum granulosum ovarii. (05 Mar 2000) |
| growing ovarian follicle | A follicle having several layers of proliferating follicular cells surrounding the ovum, but separated from it by an extracellular glycoprotein layer (zona pellucida). (05 Mar 2000) |
| polyovular ovarian follicle | <gynaecology> A follicle containing more than one ovum. (05 Mar 2000) |
| hair follicle | <dermatology> A tube-like opening in the epidermis where the hair shaft develops and into which the sebaceous glands open (13 Nov 1997) |
| primary ovarian follicle | An ovarian follicle before the appearance of an antrum; marked by developmental changes in the oocyte and follicular cells so that the latter form one or more layers of cuboidal or columnar cells; the follicle becomes surrounded by a sheath of stroma, the theca. Synonym: folliculus ovaricus primarius. (05 Mar 2000) |
| 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) |
