8. Body Planes and Sections
Coronal (frontal) plane - Lies vertically and divides body into anterior (front) and posterior (back) parts

9. Body Planes and Sections
Sagittal plane – lies vertically and divides the body into left and right sides.
Median (midsagittal) plane - Specific sagittal plane that lies vertically in the midline

10. Body Planes and Sections
Transverse plane - runs horizontally and divides body into superior (up) and inferior (down) parts

11. Body Cavities and Membranes
Dorsal body cavity
Cavity subdivided into:
Cranial cavity houses the brain.
Vertebral cavity runs through the vertebral column and encloses the spinal cord

12. Body Cavities and Membranes
Ventral body cavity – subdivided into:
Thoracic cavity – divided into three parts
Abdominopelvic cavity – divided into two parts

13. Body Cavities and Membranes
Ventral body cavity – subdivided into:
Thoracic cavity – divided into three parts
Two lateral parts each containing a lung surrounded by a pleural cavity
Mediastinum – contains the heart surrounded by the pericardial sac

14. Body Cavities and Membranes
Ventral body cavity
Abdominopelvic cavity – divided into 2 parts
Abdominal cavity – contains the liver, stomach, kidneys, and other organs
Pelvic cavity – contains the bladder, some reproductive organs, and rectum

15. Body Cavities and Membranes
Serous cavities – a slit-like space lined by a serous membrane
Pleura, pericardium, and peritoneum
Parietal serosa – outer wall of the cavity
Visceral serosa covers the visceral organs
