Anatomy and Physiology 1- Body Cavities, Planes, and Regions

Cranial cavity

formed by cranial bones and contains the brain

Vertebral canal

formed by the vertebral column and contains the spinal cord

Thoracic cavity

chest cavity which contains the mediastinum and pericardial cavities

Mediastinum

a division in the thoracic cavity between the lungs which contains all viscera but the lungs

Pericardial cavity

the cavity that contains the heart

Pleural cavities

the cavities which contain the lungs

Abdominopelvic cavity

the cavity inferior to the diaphragm which is divided into the abdominal and pelvic cavities

Abdominal cavity

Contains the stomach, small intestine, most of the large intestine, appendix, liver, gallbladder, pancreas, and spleen

Pelvic cavity

contains the urinary bladder, reproductive organs, and a portion of the large intestine

Viscera
