pulp cavity the pulp-filled central chamber in the crown of a tooth.
cavity of septum pellucidum the median cleft between the two laminae of the septum pellucidum. Called also pseudocele, pseudocoele, and fifth ventricle.
serous cavity a coelomic 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 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(kav'it-e) [L. cavitas, hollow]
A hollow space, such as a body organ or the hole in a tooth produced by caries.
The ventral cavity between the diaphragm and pelvis, containing the abdominal organs. It is lined with a serous membrane, the peritoneum, and contains the following organs: stomach with the lower portion of the esophagus, small and large intestines (except sigmoid colon and rectum), liver, gallbladder, spleen, pancreas, adrenal glands, kidneys, and ureters. It is continuous with the pelvic cavity; the two constitute the abdominopelvic cavity. See: abdomen; abdominal quadrants for illus.
A tooth socket.
The synovial cavity of a joint.
1. Any hollow space within the body. See: illustration
2. A hidden body space that is accessible from the outside, e.g., rectum or vagina. Referred to in “body cavity search for contraband”.
3. Derivatives of the coelom, i.e., the pericardial, peritoneal, and plural sacs. See: coelom
buccal cavityOral cavity.
The cavity of the skull, which contains the brain.
The body cavity composed of the cranial and spinal cavities. See: body cavity for illus.
glenoid cavityGlenoid fossa (2).
The articular cavity or space enclosed by the synovial membrane and articular cartilages. It contains synovial fluid. Synonym: joint space
The hollow inside the larynx from its inlet at the laryngopharynx to the beginning of the trachea. It has three segments (from top to bottom): vestibule of the larynx, ventricle of the larynx, infraglottic cavity.
lesser peritoneal cavityOmental bursa.
The marrow-filled space in a bone.
One of two cavities between the floor of the cranium and the roof of the mouth, opening to the nose anteriorly and the nasopharynx posteriorly. Its lining of ciliated epithelium warms and moistens inhaled air, and traps dust and pathogens on mucus that are then swept toward the pharynx. The nasal septum (ethmoid and vomer) separates the nasal cavities, and the olfactory receptors are in the upper part of each cavity. The paranasal sinuses (frontal, maxillary, sphenoidal, and ethmoidal) open into the meatus below the conchae. The orifices of the frontal, anterior ethmoidal, and maxillary sinuses are in the middle meatus. The orifices of the posterior ethmoidal and sphenoidal sinuses are in the superior meatus. The nasal mucosa is highly vascular; blood is supplied by the maxillary arteries from the external carotid arteries and by the ethmoidal arteries from the internal carotid arteries.
The space inside the teeth and gums that is filled by the tongue when the mouth is closed and relaxed.Synonym: buccal cavity
The bony hollow formed by the innominate bones, the sacrum, and the coccyx. The major pelvic cavity lies between the iliac fossae and above the iliopectineal lines. The minor pelvic cavity lies below the iliopectineal lines. See: pelvis
The potential space between the epicardium (visceral pericardium) and the parietal pericardium.See: pericardia friction rub; pericarditis
The potential space between the parietal peritoneum, which lines the abdominal wall, and the visceral peritoneum, which forms the surface layer of the visceral organs. It contains serous fluid.
The potential space between the parietal pleura that lines the thoracic cavity and the visceral pleura that covers the lungs. It contains serous fluid that prevents friction.
The ventral body cavity.See: body cavity for illus.; coelom
The cavity in a tooth containing blood vessels and nerve endings.
The anatomic intensifiers of the human voice, including the upper portion of the larynx, pharynx, nasal cavity, paranasal sinuses, and oral cavity.
Rosenmüller cavitySee: Rosenmüller, Johann Christian
The space between two layers of serous membrane (e.g., the pleural, pericardial, and peritoneal cavities).
The cavity that contains the spinal cord. See: body cavity for illus.
Any of the cavities of the body, such as the cranial, thoracic, and abdominal cavities, that contain important organs.
The part of the ventral cavity above the diaphragm, the domed muscle that separates it from the abdominal cavity; it is enclosed by the chest wall. The thoracic viscera include the pleural membranes that surround the lungs, the mediastinum between the lungs, which contains the heart and pericardial membranes, the thoracic aorta, pulmonary artery and veins, vena cavae, thymus gland, lymph nodes, trachea, bronchi, esophagus, and thoracic duct. See: illustration
tympanic cavityMiddle ear.
The hollow space inside the body of the uterus.
The body cavity composed of the thoracic, abdominal, and pelvic cavities. See: body cavity for illus.
The body cavity containing the viscera (i.e., the thorax, abdomen, and pelvis).
