  1. The Human Body: An Orientation

  2. The Language of Anatomy • Special terminology is used to prevent misunderstanding • Exact terms are used for • Position • Direction • Regions • Structures

  3. Regional Terms • Anterior body landmarks Figure 1.5a

  4. Regional Terms • Posterior body landmarks Figure 1.5b

  5. Directional Terms Table 1.1 (1 of 3)

  6. Directional Terms Table 1.1 (2 of 3)

  7. Directional Terms Table 1.1 (3 of 3)

  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

  9. Body Planes and Sections Figure 1.6

  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
