1. Body Planes & Cavities Notes

2. Body Planes/Sections
Imaginary flat surfaces that divide the body or organs
Sagittal (medial) – divides body into right and left portions
Frontal (coronal) – divides body into anterior and posterior sections

3. Transverse (cross-section) – divides body into superior and inferior portions

7. Body Cavities space that remains after organs inside it are removed
Two major:
Dorsal Body Cavities – made up of cranial and spinal cavities
Ventral Body Cavities – contains all structures of chest and abdomen

8. Dorsal divided into:
Cranial Cavity – space inside skull; houses brain
Spinal Cavity – houses spinal cord

9. Ventral divided into:
Thoracic Cavity – upper chest area; houses lungs, heart, etc.
Mediastinum – houses heart
Adominopelvic Cavity – made up of abdominal and pelvic cavities
Divided by the diaphragm

10. Abdominopelvic cavity divides into:
Abdominal Cavity – houses stomach, liver, intestines etc.
Pelvic Cavity – houses reproductive organs, rectum, bladder

13. 4 Quadrants Compartmentalizes organs into 4 sections
Right and left upper quadrants
Right and left lower quadrants

15. Nine Regions Divides the abdominopelvic cavity into nine sections
Umbilical – centermost; visceral or abdominal pain
Epigastric – superior to umbilical; heartburn

16. Nine Regions Hypogastric (Pubic) – inferior to umbilical
Right Iliac (Inguinal) – right of hypogastric
Left Iliac (Inguinal) – left of hypogastric; gas pain

17. Nine Regions Right Lumbar – right of umbilical
Left Lumbar – left of umbilical
Right hypochondriac – right of epigastric

18. Nine Regions
Left hypochondriac – left of epigastric
