Body Cavity

body cavity

[′bäd·ē ‚kav·əd·ē] (anatomy) The peritoneal, pleural, or pericardial cavities, or the cavity of the tunica vaginalis testis.

Body Cavity

in animals and man, the space bounded by the internal surface of the body wall. The internal organs are distributed in the body cavity. The primary body cavity does not have a wall, whereas the secondary body cavity, or coelom, is lined with sheets of epithelial mesodermal cells. In vertebrates the secondary body cavity is divided into the pericardial cavity and the abdominal cavity. In mammals, including man, the abdominal cavity is divided by the diaphragm into the thoracic cavity, which is lined with the pleura and contains the lungs, and the abdominal cavity proper, which is lined with the peritoneum and contains the digestive, excretory, and sex organs.

body cavity

bod·y cav·i·ty

the collective visceral cavity of the trunk (thoracic cavity plus abdominopelvic cavity), bounded by the superior thoracic aperture above, the pelvic floor below, and the body walls (parietes) in between. Synonym(s): celom (2) , celoma, coelom (1)

body cavity

n.1. See coelom.2. Any of the cavities of the body that adjoin external orifices, such as the mouth or rectum.

body cavity

Any space in the body that does not freely communicate with the outside. Body cavities are covered with specialised lining cells—e.g., mesothelial cells in the pericardium, peritoneum and pleura.
Body cavity types
• Major—Pericardial, pleural, peritoneal, cerebrospinal.
• Minor—Amniotic, anterior chamber of the eye, cul de sac, hydrocele, oral cavity, synovial, vitreous.

CAVITIES OF THE BODY

body cavity

CAVITIES OF THE BODY1. Any hollow space within the body. See: illustration2. 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: coelomSee also: cavity

body cavity

the space within the body of most animals in which the gut and various organs are suspended. It normally contains fluid and is derived embryologically in different ways in different groups of animals. Absent in PLATYHELMINTHS and NEMERTINE worms, it is derived from the COELOM in vertebrates and from the HAEMOCOEL in arthropods and molluscs. It occurs as an intercellular space in nematode worms.
