Dorsal body cavity
has two subdivisions, which are continuous with each other
cranal cavity
is the space inside the bony skull
spinal cavity
extends from the cranial cavity to the end of the spinal cord
ventral body cavity
is much longer than the dorsal cavity, contains all the structures within the chest and abdomen, that is the visceral organs in those regions
thoracic cavity
is seperated from the rest of the ventral cavity by a domed shape muscle
diaphgram
a domed shaped muscle
mediastinum
seperates the lungs into right and left cavities in the thoracic cavities, houses the heart, trachea, and several other visceral organs.
abdominopelvic cavity
cavity inferior to the diaphragm
abdominal cavity
containing the stomach, liver, intestines, and other organs
pelvic cavity
contains the reproductive organs, bladder, and rectum
umbilical region
is the centermost region deep to and surrounding the umbilicus (navel).
umbilical region
is the centermost region deep to and surrounding the umbilicus (navel).
epigastric region
is located superior to the umbilical region upon, above gastric (stomach) region
hypogastric(pubic) region
is inferior to the umbilical region
right iliac (inguinal) region
contains the appendix, cecum, and the right iliac fossa.
left iliac (inguinal) region
contains part of the descending colon, the sigmoid colon, and the left illiac fossa.
Right lumbar region and left lumbar region
lie lateral to the umbilical region and spinal column between the bottom ribs and the hip bones
right hypochondriac region and left hypochondriac region
Flank the epigastric region and contain the lower ribs (chondro= cartilage
Oral cavity and digestive cavity
The oral cavity, or the mouth, contains the teeth and tongue. This cavity is part of and continuous with the digestive organs, which open to the exterior at the anus.
nasal cavity
located within and posterior to the nose, part of the respiratory system.
The nine abdominopelvic regions
The abdominopelvic cavity is divided into nine regions by four planes in this scheme used mostly by anatomists. In (a), the superior transverse plane is just superior to the ribs; the inferior transverse plane is just superior to the hip bones; and the parasagittal planes lie just medial to the nipples.
