  1. Body Planes, Directions, and Cavities

  2. Body Planes • Imaginary lines drawn through the body to separate the body into sections

  3. Transverse Plane • A horizontal plane dividing the body into a top and bottom half • Superior = body parts above others • Inferior = body parts below others

  4. Median/(Mid)Sagittal Plane • Divides the body into right and left sides • Medial = body parts located near the middle/midline of the body • Lateral = body parts located away from the middle/midline of the body

  5. Frontal/Coronal Plane • Divides the body into front and back sections • Anterior (Ventral) = body parts on the front of the body • Posterior (Dorsal) = body parts on the back of the body

  6. Additional Directional Terms: • Superficial = towards the surface • Deep = internal • Proximal = body parts closer to the point of reference (where the limb joins the body) • Distal = body parts farther from the point of reference (where the limb joins the body) • **Proximal and distal are only used when referring to the limbs**

  7. Body Cavities • Spaces within the body which contain vital organs • Dorsal Body Cavity • Cranial cavity • Spinal cavity • Ventral Body Cavity • Thoracic cavity • Diaphragm—dome-shaped muscle that aids in breathing and separates the thoracic and abdominopelvic cavities • Abdominopelvic cavity

  8. Dorsal Body Cavity • Cranial Cavity • Contains the brain • Spinal Cavity • Contains the spinal cord

  9. Ventral Body Cavity • Thoracic Cavity • Pleural cavity = contains the lungs • Pericardial cavity = contains the heart • Mediastinum = central region that separates the lungs sits between the sternum and the vertebral column

  10. Ventral Body Cavity (ctd.) • Abdominopelvic cavity • Abdominal cavity = upper part; contains the stomach, small intestines, most of the large intestines (except colon and rectum), liver, gallbladder, pancreas and spleen • Pelvic cavity = lower part; contains the urinary bladder, reproductive organs, and the last part of the large intestine (colon and rectum)

  11. Abdominal Regions and Quadrants
