Body planes and sections

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

Body cavities

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
