8. Body Planes and Sections
A sagittal section divides the body (or organ) into left and right parts
A median, or midsagittal, section divides the body (or organ) into equal left and right parts
A frontal section divides the body (or organ) into anterior and posterior parts
A transverse, or cross, section divides the body (or organ) into superior and inferior parts

10. Body Cavities Dorsal body cavity Cranial cavity houses the brain
Spinal cavity houses the spinal cord
Ventral body cavity
Thoracic cavity houses heart, lungs and others
Abdominopelvic cavity houses digestive system and most urinary system organs

11. Body Cavities Thoracic cavity subdivisions: Two pleural cavities
Each houses a lung
Mediastinum
Contains pericardial cavity
Surrounds thoracic organs
Pericardial cavity
Encloses heart

12. Serous Membranes
Thin, double-layered membrane separated by serous fluid
Parietal serosa lines internal body walls
Visceral serosa covers the internal organs
