dorsal
Cavity located in the back part of the body; two subdivisions are cranial and vertebral (spinal) cavities
ventral
Cavity located in the front part of the body; two subdivisions are thoracic and abdominopelvic
thoracic
Chest cavity that includes left and right pleural cavities, pericardial cavity, and a midportion called the mediastinum (not a cavity)
pleural
Cavity located in the left and right sides of the thoracic cavity; contain the lungs
mediastinum
Middle portion of the thoracic (chest) cavity that contains the heart, trachea, esophagus, thymus, and several blood vessels.
abdominopelvic
Cavity that is subdivided into abdominal and pelvic cavities
spinal or vertebral
Cavity that is part of the dorsal cavity containing the spinal cord
parietal
Serous membranes are classified based on their location. __________________ serous membranes line the cavity walls
visceral
Serous membranes are classified based on their location. __________________ serous membranes cover the surfaces of organs
axial region
Term used to describe the area that consists of the head, neck, and torso or trunk
pleura
Serous membrane associated with the lungs
pericardium
Serous membrane associated with the heart
peritoneum
Serous membrane associated with the abdominal cavity
sagittal
General term for the vertical plane that divides the body or organ into right and left sides
midsagittal
Vertical plane that divides the body into equal left and right sides
parasagittal
Sagittal plane that does not pass through the midline but instead divides the body into unequal right and left sides
frontal
Plane that divides the body or organ into anterior and posterior portions. Also called coronal
transverse
Plane that divides the body or an organ into upper and lower portions. Also called a cross-sectional plane
oblique
Plane that passes through the body or organ at an angle other than 90 degrees
visceral pleura
Serous membrane that lines the surface of the lungs
visceral peritoneum
Serous membrane that lines the surface of the liver, stomach, spleen, and many other abdominal organs
visceral pericardium
Serous membrane that lines the surface of the heart (also called the epicardium)
parietal pleura
Serous membrane the lines the chest wall around the lungs and covers the superior surface of the diaphragm
parietal peritoneum
Serous membrane that lines the abdominal wall and covers the inferior surface of the diaphragm
retroperitoneal
Term used to describe organs that are located between the parietal peritoneum and posterior abdominal wall. Example organs include the kidneys, adrenal glands, pancreas, duodenum of small intestine, ascending and descending colons and the abdominal aorta and inferior vena cava
ascites
Condition in which there is distention of the peritoneal cavity due to accumulation of several liters of serous fluid
Mediastinum
Region between the sternum, vertebrae and lungs and is not a distinct body cavity. Contains the esophagus, trachea, blood vessels, thymus and pericardial cavity
pelvic cavity
Part of the abdominopelvic cavity that contains the urinary bladder, portions of the large intestine and internal reproductive organs.
Pleurisy
Inflammation of the serous membrane that lines the lungs and lung cavity.
Ascites
Distention of the peritoneal cavity due to accumulation of several liters of serous fluid.
