Skeletal System
Body Planes and Cavities
| Question | Answer |
|---|---|
| Vertical Plane | up and down |
| Horizontal Plane | Flat, crosswise |
| 3 vertical planes | Midsagittal, Sagittal, Coronal |
| Midsagittal Plane | AKA midline, divides the body into equal L & R . (down the center) |
| Sagittal Plane | divides the body into unequal L & R body parts. |
| Coronal Plane | AKA frontal, divided the body into anterior & posterior (front & back) |
| Transverse plane (horizontal plane) | <-----> divides the body into superior & inferior (upper & lower) |
| Body cavity | the space within that body that contains & protects the interal organs. |
| Dorsal Cavity | protects the nervous system and coordinates body functions |
| Cranial Cavity | the brian and spinal cavity |
| Ventral Cavity | contains body organs that mantian homestasis |
| 3 parts of the ventral cavity | Thoracic, Abdominal & Pelvic |
| Thoracic Cavity | protects heart & lungs |
| Diaphragm | a dome shaped musculsr fibrous portion that seperates the thoracic & abdominal cavities. Helps a person to breathe. |
| Abdominal cavity | contains organs of digestion |
| Pelvic Cavity | contains organs of reproduction and excretory system (urinary) |
| ventral/Anterior | Front |
| dorsal/posterior | back |
| superior/cephalic | toward the head |
| inferior/caudal | toward the feet |
| proximal/medial | toward the midline |
| distal/lateral | away from the midline |
| 4 regions of the abdomen | RUQ, LUQ, RLQ, LLQ |
| RUQ | part of the live, gallbladder, pancreas & intestinal tract |
| LUQ | stomach, spleen, part of liver, pancreas & intestines |
| RLQ | appendix, intestines, reproductive organs & urinary tract |
| LLQ | intestines, reproductive organs and urinary |
| Nine regions of the thoracic & abdomen | R&L hyprochondriac,Epigastric, R&L Lumbar, umbilical, R&L iliac, hypogastric |
| Cell | cells are the basic structual unit of the human body. need food, water & oxygen to live & function |
