1. Body Planes, Directions, Cavities and Abdominal Regions

2. Anatomical Position stand erect face forward arms at side
palms facing forward
feet slightly apart

3. Three main body planes:
Transverse (horizontal) plane:
divides into top and bottom
Midsagittal (median) plane: divides into equal left and right halves
Frontal (coronal) plane: divides into front (anterior, ventral) and back (posterior, dorsal)

5. Use proximal and distal when referring to
the extremities (arms and legs).

6. Body Cavities cranial cavity: brain spinal cavity: spinal cord
thoracic cavity: esophagus, lungs, heart
upper abdominal cavity: stomach, small intestine, liver, gallbladder, most of large intestine
pelvic cavity (lower abdominal): urinary bladder, reproductive organs, last part of the large intestine

7. Body Cavities (continued)
orbital cavity: eyes
nasal cavity: nose structures
buccal cavity: teeth and tongue

8. Abdominal Regions right upper quadrant RUQ left upper quadrant LUQ
right lower quadrant RLQ
left lower quadrant LLQ

9. A more precise method of dividing the abdominal area.
