abdominal
center anterior region of the trunk
brachial
arm region
cephalic
head region
cervical
neck region
crural
lower extremity region
dorsum
posterior region (the back)
gluteal
buttocks region
pelvic
lower anterior region of the trunk
pubic
genital region
thoracic

cavity
empty space
two major cavities
dorsal and ventral
dorsal cavity
cranial and spinal cavity / houses brain and spinal cord
ventral cavity
combines thoracic and abdominopelvic cavities
cranial cavity
formed by the skull, holds and protects the brain
(located in dorsal cavity)
spinal cavity
protects the spinal cord
aka: vertebral canal
(located in dorsal cavity)
pleural cavities
There are two
each contain a lung
pericardial cavity
contains the heart
is medial to the pleural cavities
mediastinum
contains esophagus, trachea, thymus gland, aorta, and inerior vena cavae
serous membrane
outer lining of organs and body cavities of the abdomen and chest, including the stomach
(reduces friction of organs and walls of cavities)
serous fluid
secreted by epithelium of the serous membrane
pleura
two-layer membrane in the thoracic cavity
parietal pleura
out layer of membrane in the thoracic cavity
visceral pleura
inner layer of membrane in the thoracic cavity
abdominopelvic cavity
combination of the abdominal and pelvic cavities
peritoneum
two layer membrane in the abdominopelvic cavity
parietal peritoneum
outer layer of membrane in the abdominopelvic cavity
visceral peritoneum
inner layer of membrane in the abdominopelvic cavity
abdominal cavity contains
stomach, spleen, liver, gallbladder, pancreas, most of the small intestine and colon
(superior to pelvic cavity)
pelvic cavity contains
urinary bladder, ureters, urethra, lower part of large intestine, prt of the small intestine, female reproductive organs, and some male reproductive organs
(inferior to the abdominal cavity)
right upper quadrant (RUQ)
contains majority of liver, gallbladder, portion of pancreas, right kidney, portion of small intestines and colon
left upper quadrant (LUQ)
contains portion of liver, spleen, stomach, ,majority of pancreas, left kidney, small portion of small intestines and colon
right lower quadrant (RLQ)
contains half of small intestines and colon, right ovary and fallopian tube, appendix, and the right ureter
left lower quadrant (LLQ)
contains half of the small intestines and colon, left ovary and fallopian tube, and the left ureter
9 regions of the abdominal cavity
right hypochondriac
epigastric
left hyphochondriac
right lumbar
umbilical
left lumbar
hypogastric
left iliac
right iliac
right hypochonriac
lateral to the epigastric region, beneath the lower ribs
epigastric
superior to umbilical region, above the stomach
left hypochondriac
lateral to the epigastric region, beneath the lower ribs
right lumbar
lateral to the umbilical region, at the waist
umbilical
central, surrounding the navel
left lumbar
lateral to the umbilical region, at the waist
hypogastric
inferior to the umbilical region, below the navel
left iliac
lateral to the hypogastric region, at the groin - left side
right iliac
lateral to the hypogastric region, at the groin - right side
thoracic cavity contains
heart, lungs, trachea, esophagus
