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.

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.

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.

cranial cavity,

the cavity of the skull containing the brain and other tissues. Also called cerebral cavity.

---

cavity

1. a hollow or space, or a potentional space, within the body (e.g. abdominal cavity) or one of its organs (e.g. cranial cavity).

2. in teeth, the lesion produced by dental caries.

absorption c's

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.

cranial cavity

the space enclosed by the bones of the cranium.

dental cavity

1. the central space, often branched or multiple in compound teeth, of each tooth; carries the nerve and blood supplies to the teeth.

2. the defect caused by decay on a tooth surface. Called also caries.

glenoid cavity

a depression in the ventral angle of the scapula for articulation with the humerus.

infraglottic cavity

the space in the larynx caudal to the vocal folds; reflects the shape of the cricoid cartilage.

medullary (marrow) cavity

the cavity, containing marrow, in the diaphysis of a long bone; called also medullary canal.

nasal cavity

the proximal part of the respiratory tract, within the nose, bisected by the nasal septum and extending from the nares to the pharynx. Much of the cavity is occupied by the turbinate bones or conchae which also divide it into dorsal, medial and ventral meatuses. The common meatus is the narrow, vertical passage close to the nasal septum. The rostral end of the cavity just inside the nostril is the nasal vestibule, and the caudal part opening into the pharynx is the nasopharyngeal meatus.

oral cavity

the cavity of the mouth, made up of a vestibule and oral cavity proper.

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 the visceral pleura.

pulp cavity

the pulp-filled central chamber in a tooth; called also dental cavity.

serous cavity

a celomic cavity, like that enclosed by the pericardium, peritoneum or pleura, not communicating with the outside of the body and lined with a serous membrane, i.e. one which secretes a serous fluid.

tension cavity

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

thoracic cavity

the body cavity situated between the neck and the diaphragm.

tympanic cavity

the cavity of the middle ear.

uterine cavity

the space within the uterus communicating on either side with the uterine tubes and caudally with the vagina.
