Pleural cavity
The area of the chest that includes the lining of the chest cavity, the space the lungs are located in, and the membrane covering of the lungs.
pleural cavity
Etymology: Gk, pleura, rib; L, cavum, cavity
the space within the thorax that contains the lungs. Between the ribs and the lungs are the visceral and parietal pleurae.

thoracic cavity the portion of the ventral body cavity situated between the neck and the diaphragm; it contains the pleural cavity.
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 and communicates with the mastoid air cells and the mastoid antrum by means of the aditus and the nasopharynx by means of the auditory tube. The middle ear and the tympanic cavity were formerly regarded as being synonymous.
uterine cavity the flattened space within the uterus communicating proximally on either side with the fallopian tubes and below with the vagina.
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.

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.
