Follicles
Follicles Each month several of these small egg-containing cavities develop on the ovary of an ovulating woman. Each cavity contains a single immature egg; ovulation occurs when a follicle (or sometimes more than one) ruptures and releases an egg.
RELATED TERMS--------------------------------------
Cavities
Holes in the two outer layers of a tooth called the enamel and the dentin. The enamel is the outermost white hard surface and the dentin is the yellow layer just beneath enamel. Both layers serve to protect the inner living tooth tissue called the pulp, where blood vessels and nerves reside. Small cavities may not cause pain, and may be unnoticed by the patient. Larger cavities can collect food, and the inner pulp of the affected tooth can become irritated by bacterial toxins, foods that are cold, hot, sour, or sweet - causing toothache. Also referred to as caries.
