Body Plane and Cavities Flashcards
any fluid-filled space in a multicellular organism other than those of vessels (such as blood vessels and lymph vessels)
-refers to the ventral body cavity
Human Body Cavity
two sets of cavities
Dorsal Body Cavity
Ventral Body Cavity
protects fragile nervous system
Dorsal Body Cavity
has two subdivisions
- Cranial Cavity
- Vertebral Cavity
Dorsal Body Cavity
encases cavity
Cranial Cavity
encases spinal cavity
Vertebral Cavity
houses the internal organs collectively called viscera
Ventral Body Cavity
has two subdivisions
- Thoracic Cavity
- Abdominopelvic Cavity
Ventral Body Cavity
includes the heart, lungs, trachea, and esophagus
Thoracic Cavity
includes the gallbladder, liver, pancreas, intestines, diaphragm, stomach, spleen, kidneys, and reproductive organs
Abdominopelvic Cavity
- two pleural cavities
- mediastinum
- pericardial cavity
Thoracic Cavity
contains the lungs; each cavity surrounds one lung
Pleural Cavity
contains pericardial cavity; surrounds other thoracic organs, such as esophagus, trachea, etc
Mediastinum
contains the heart; encloses the heart
Pericardial Cavity
- abdominal cavity
- pelvic cavity
Abdominopelvic Cavity
contains the stomach, intestines, spleen, and liver
Abdominal Cavity
contains urinary bladder, reproductive organs, and rectum
Pelvic Cavity
abdominopelvic region is sectioned
Quadrants
- right upper quadrant
- left upper quadrant
- right lower quadrant
- left lower quadrant
Quadrants
nine divisions resembling a tic-tac-toe grid are used primarily by anatomists
Regions
- right hypochondriac region
- epigastric region
- left hypochondriac region
- right lumbar region
- umbilical region
- left lumbar region
