5. Body Cavities
Dorsal cavity protects the nervous system, and is divided into two subdivisions
Cranial cavity is within the skull and encases the brain
Vertebral cavity runs within the vertebral column and encases the spinal cord
Ventral cavity houses the internal organs (viscera), and is divided into two subdivisions: - Thoracic and Abdominopelvic cavities

6. Body Cavities
Figure 1.9b

7. Body Cavities Pleural cavities – each houses a lung
Thoracic cavity is subdivided into pleural cavities, the mediastinum, and the pericardial cavity
Pleural cavities – each houses a lung
Mediastinum – contains the pericardial cavity, and surrounds the remaining thoracic organs
Pericardial cavity – encloses the heart

8. Body Cavities
The abdominopelvic cavity is separated from the superior thoracic cavity by the dome-shaped diaphragm
It is composed of two subdivisions
Abdominal cavity – contains the stomach, intestines, spleen, liver, and other organs
Pelvic cavity – lies within the pelvis and contains the bladder, reproductive organs, and rectum

10. Other Body Cavities
Oral and digestive – mouth and cavities of the digestive organs
Nasal –located within and posterior to the nose
Orbital – house the eyes
Middle ear – contain bones (ossicles) that transmit sound vibrations
Synovial – joint cavities

Spinal cord
Lungs
Brain
Liver
Bladder
