Basic Human Body: Body Cavities, Planes, Sections & Division Flashcards
Dorsal Cavity
Posterior (back) side
- Cranial cavity (space for the brain)
- Vertebral Canal (Spinal canal is formed by the vertebrae through which the spinal cord passes)
Ventral Cavity
- Thoracic cavity (aka chest cavity)
- Diaphragm (muscle which separates Thoracic and Abdominal cavity)
- Abdominal cavity
- Pelvic cavity
Planes and Sections
Longitudinal planes of the upright body
- Frontal or Coronal
- Median
- Sagittal
Horizontal planes of the upright body
- Transverse (aka cross-section)
Median Plane
Divides the body into a equal left and right section (mid sagittal)
Sagittal Plane
Divides the body into an unequal left section and right section (parallel to the median plane)
Frontal or Coronal Plane
Divides the body into a front section and back section (plane goes side to side)
Transverse Plane
Divides the body into an upper section and lower section
(plane splits body in half at waist)
aka cross-section
Abdominal Division
• QUADRANTS • NINE AREAS – UPPER GASTRIC AREA – LOWER GASTRIC AREA – MIDDLE GASTRIC AREA – LOWER AREAS
4 Quadrants (Abdominal Quadrants)
Top quadrant - right to left
- Right upper quadrant (RUQ)
- Left upper quadrant (LUQ)
Bottom quadrant - right to left
- Right lower quadrant (RLQ)
- Left lower quadrant (LLQ)
Organs in Right Upper Quadrant (RUQ)
- Liver & Gallbladder
- Pylorus
- Duodenum
- Head of pancreas
- Portions of ascending & transverse colon
- Right adrenal gland
- Right kidney
Organs in Left Upper Quadrant (LUQ)
- Left lobe of liver
- Spleen
- Stomach
- Body of pancreas
- Portion of descending and transverse colon
- Left adrenal gland
- Left kidney
Organs in Right Lower Quadrant (RLQ)
- Small bowel
- Appendix & cecum
- Ascending colon
- Right kidney
- Right ureter
- Ovary
Organ in Left Lower Quadrant (LLQ)
- Small bowel
- Sigmoid colon
- Descending colon
- Left kidney
