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 |
