follicle

a sac or pouchlike depression or cavity.
atretic follicle
an involuted ovarian follicle.
conjunctival follicle
focal accumulations of hypertrophied lymphoid tissue in conjunctiva, indicative of an inflammatory reaction.
cystic follicle
ovarian follicle that has not ruptured, is grossly enlarged, may be multiple and on both ovaries. Caused by insufficient luteinizing hormone. Affected cows may be nymphomaniac in behavior, but most are anestrous and anovulatory. See also cystic ovarian degeneration.
dental follicle
the structure within the substance of the jaws enclosing a tooth before its eruption; the dental sac and its contents.
dominant follicle
in the ovary, hormones secreted by the largest follicle will cause others to regress.
gastric follicle
lymphoid masses in the gastric mucosa.
graafian follicle
a maturing ovarian follicle among whose cells fluid has begun to accumulate, leading to the formation of a single cavity and leaving the ovum located in the cumulus oophorus; called also vesicular ovarian follicle.
hair follicle
see hair follicle.
hemorrhagic follicle
see corpus hemorrhagicum.
lymph follicle, lymphatic f
1. a small collection of actively proliferating lymphocytes in the cortex of a lymph node.
2. a small collection of lymphoid tissue in the mucous membrane of the gastrointestinal tract; such collections may occur singly (solitary lymphatic follicle) or closely packed together (aggregated lymphatic follicles).

EXPRESSION OF CD 10 IN DENTIGEROUS CYSTS AND AMELOBLASTOMAS A RELIABLE PROGNOSTICATOR
Pericoronal space surrounding the impacted third molar may represent either a normal or an enlarged dental follicle but alternatively may represent a patho-logic entity most commonly a dentigerous cyst.
The probable reason for this appears to be that the follicle was separated from its associated tooth and the lining epithelium was of enamel organ type, most of it re-mained attached to the enamel of the tooth and conse-quently was not seen in the microscopic section of the dental follicle.
The aim of this study was to establish radiographic criteria for early diagnosis of cystic changes in dental follicles associated with impacted third molars and thereby prevent the development of a pathological cyst and its associated complications.
