1. a hollow place or space, or a potential space, within the body or one of its organs.

2. in dentistry, the lesion produced by caries.

abdominal cavity  the cavity of the body between the diaphragm and pelvis, containing the abdominal organs.

absorption cavities  cavities in developing compact bone due to osteoclastic erosion, usually occurring in the areas laid down first.

amniotic cavity  the closed sac between the embryo and the amnion, containing the amniotic fluid.

cleavage cavity  blastocoele.

complex cavity  a carious lesion involving three or more surfaces of a tooth in its prepared state.

compound cavity  a carious lesion involving two surfaces of a tooth in its prepared state.

cotyloid cavity  acetabulum.

cranial cavity  the space enclosed by the bones of the cranium.

dental cavity  the carious defect (lesion) produced by destruction of enamel and dentin in a tooth.

glenoid cavity  a depression in the lateral angle of the scapula for articulation with the humerus.

marrow cavity , medullary cavity the cavity in the diaphysis of a long bone containing the marrow.

nasal cavity  the proximal part of the respiratory tract, separated by the nasal septum and extending from the nares to the pharynx.

oral cavity  the cavity of the mouth, bounded by the jaw bones and associated structures (muscles and mucosa).

pelvic cavity  the space within the walls of the pelvis.

pericardial cavity  the potential space between the epicardium and the parietal layer of the serous pericardium.

peritoneal cavity  the potential space between the parietal and the visceral peritoneum.

pleural cavity  the potential space between the parietal and visceral pleurae.

pleuroperitoneal cavity  the temporarily continuous coelomic cavity in the embryo that is later partitioned by the developing diaphragm.

prepared cavity  a lesion from which all carious tissue has been removed, preparatory to filling of the tooth.

pulp cavity  the pulp-filled central chamber in the crown of a tooth.

Rosenmüller's cavity  pharyngeal recess.

serous cavity  a coelomic cavity, like that enclosed by the pericardium, peritoneum, or pleura, not communicating with the outside body, and whose lining membrane secretes a serous fluid.

sigmoid cavity 

1. either of two depressions in the head of the ulna for articulation with the humerus.

2. a depression on the distal end of the medial side of the radius for articulation with the ulna.

simple cavity  a carious lesion whose preparation involves only one tooth surface.

somatic cavity  the intraembryonic portion of the coelom.

tension cavities  cavities of the lung in which the air pressure is greater than that of the atmosphere.

thoracic cavity  the part of the ventral body cavity between the neck and the diaphragm.

tympanic cavity  the major portion of the middle ear, consisting of a narrow air-filled cavity in the temporal bone that contains the auditory ossicles.

uterine cavity  the flattened space within the uterus communicating proximally on either side with the uterine tubes and below with the vagina.
