L5- Body Cavity Flashcards
two subdivisions which are continuous with each other
dorsal body cavity
2 dorsal body cavity
- cranial cavity
- spinal cavity
space inside the bony skull
cranial cavity
extends from the cranial cavity to the end of the spinal cord
spinal cavity
(larger than the dorsal cavity) contains all the structures within the chest and the abdomen, the visceral organs in those regions
ventral body cavities
3 types of ventral cavities
- thoracic cavity
- mediastinum cavity
- abdominoplevic cavity
separated from the rest of the ventral cavity by a dome-shaped muscle, diaphragm
thoracic cavity
central region which separates the lungs into right and left cavities in the thoracic cavity
mediastinum
cavity inferior to the diaphragm
abdominapelvic cavity
contains the reproductive organs
pelvic cavity (bladder and rectum)
line the trunk cavities and cover the organs of these cavities
serous membranes
two serous membrane
- visceral serous membrane
- parietal serous membrane
inner part of the serous membrane
visceral serous membrane
outer part of the serous membrane
parietal serous membrane
surrounds the heart
pericardial cavity
