Paranasal sinuses
|

Paranasal sinuses Air cavities within the facial bones, lined by mucous membranes similar to those in other parts of the airways.
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.
Mucous
Adj. Relating to or resembling mucus.
Membranes
Also know as the bag of waters, this thin sac contains the amniotic fluid and the fetus. The membranes will either rupture spontaneously during labor or be ruptured to speed up labor.
