Body Cavities

  1. Dorsal Cavity
    • Cranial Cavity
    • Vertebral Cavity
  2. Cranial Cavity
    Formed by cranial bones and contains brain.
  3. Ventral Cavity
    • Thoracic Cavity
    • Abdominopelvic Cavity
  4. Thoracic Cavity
    Chest cavity; superior portion of ventral body cavity; contains pleural and pericardial cavaties and mediastinum.
  5. Vertebral Cavity
    Formed by vertebral column and contains spinal cord and the beginnings of spinal nerves.
  6. Pleural Cavity
    Each surrounds a lung; the serous membrane of the pleural vacities is the pleura.
  7. Pericardial Cavity
    Surrounds the heart; the serous membrane of the pericardial cavity is the pericardium.
  8. Mediastinum
    Central portion of thoracic cavity between the lungs; extends from sternum to vertebral column and from neck to diaphragm; contains heart, thymus, esophagus, trachea, and several large blood vessels.
  9. Abdominopelvic Cavity
    Inferior portion of ventral body cavity; subdivided inot abdominal and pelvic cavities.
  10. Abdominal Cavity
    Contains stomach, spleen, liver, gallbladder, small intestine, and most of large intestine; the serous membrane of the abdominal cavity is the peritoneum.
