  1. Unit 6:2 – Body Planes, Directions and Cavities

  2. Anatomic Position Body upright with face front, arms at the sides with palms forward, and feet parallel

  3. Frontal or Coronal Plane Midsagittal or Median Plane Transverse Plane Body Planes Imaginary lines drawn through the body to separate the body into sections

  4. Frontal or Coronal Plane Midsagittal or Median Plane Transverse Plane Body Planes Midsagittal divides the body into right and left sides Frontaldivides the body into front and back sections Transversedivides the body into top and bottom half

  5. Directions Superior – above or higher Inferior– below or lower Ventral (Anterior) – toward belly or front Dorsal (Posterior) – nearer to the back Cranial – near the head Caudal – near sacrum or tail Medial– toward the midline of the body, dividing it into left and right portions Lateral (Opposite) – toward the side, farther from the midline Proximal – nearer the origin of the structure Distal– farther from the origin of the structure

  6. Transverse Plane • Directional Terms • Superior vs. Inferior • Superior- body parts above other body parts • Ex: your shoulder is superior to your hip Inferior – body parts below other body parts • Ex: your shoulder is inferior to your head

  7. Transverse Plane • More Directional Terms • Cranial vs. Caudal • Cranial/Cephalic – near the head • Caudal – near the feet

  8. Midsagittal Plane • Directional Terms • Medial vs. Lateral • Medial – body parts close to the midline • Lateral – body parts away from the midline

  9. Frontal Plane • Directional Terms • Ventral vs. Dorsal • Ventral – body parts on the front of the body • Dorsal – body parts on the back of the body

  10. Frontal Plane • Directional Terms • Anterior vs. Posterior • Anterior – body parts on the front of the body • Posterior – body parts on the back of the body **similar to ventral and dorsal**

  11. Proximal and Distal

  12. Body Cavities Orbital Cranial Nasal Spaces within the body that contain vital organs Buccal Thoracic Dorsal Abdominal Ventral Spinal Pelvic

  13. Body Cavities DORSAL CAVITY Cranial Cavity – contains the brain Spinal Cavity – encloses spinal cord

  14. Body Cavities VENTRAL CAVITY Thoracic Cavity – contains the esophagus, trachea, bronchi, heart, lungs, and large blood vessels Abdomino-pelvic Cavity – Abdominal– contains the stomach, small intestine, most of the large intestine, appendix, liver, gallbladder, pancreas, and spleenPelvic– contains the urinary bladder, reproductive organs, and the last part of the large intestines

  15. Body Cavities ORBITAL CAVITY Contains the eyes NASAL CAVITY Contains the nose structures BUCCAL CAVITY Contains teeth and tongue

  16. Abdominal Quadrants Left Upper Quadrant - LUQ Right Upper Quadrant - RUQ Left Lower Quadrant - LLQ Right Lower Quadrant - RLQ Umbilicus

  17. Abdominal Regions Epigastric Left hypochondriac Right hypochondriac Umbilical Right lumbar Left lumbar Right iliac Left iliac Hypogastric
