Anatomical directions, regions, and parts Flashcards
directional terms
explain the relation between body structures
axial part
head, neck, torso
appendicular part
limbs attached to axis
regional terms
designate specific areas within major body divisions
sagittal plane
vertical plane dividing left from right
median plane/midsagittal plane
vertical plane directly along midline dividing left from right
parasagittal plane
vertical plane offset from the midline
frontal/coronal plane
vertical plane, dividing the anterior from posterior
transverse/horizontal plane
horizontal plane dividing superior from inferior
cross section
transverse section
oblique section
made diagonally; uncommon
dorsal body cavity
protects nervous system organs
cranial cavity
in the skull surrounding the brain
vertebral/spinal cavity
within vertebral column around spinal cord
ventral body cavity
body cavity within the torso
coelom (see-lum)
ventral body cavity
viscera
organs
thoracic cavity
superior subdivision of the ventral cavity surrounded by the ribs
pleural cavaties
surround one lung each
mediastinum
contains pericardial cavity and thoracic organs
pericardial cavity
encloses the heart
abdominopelvic cavity
inferior of the thoracic cavity, has two parts
abdominal cavity
cavity containing stomach, intestines, spleen, etc
pelvic cavity
cavity containing reproductive organs, rectum, urinary bladder
serosa/serous membrane
double-layered membrane that covers organs
organs in RLQ
appendix
organs in RUQ
liver, gallbladder
organs in LUQ
stomach, spleen
organs in LLQ
not much of note
peritoneum
membrane lining abdominopelvic cavity
peritoneal cavity
space between parietal and visceral peritoneum
peritoneal fluid
lubricant between the two layers of peritoneum
retroperitoneal organs
lie against posterior body wall, are covered by peritoneum on the internal facing side (eg. kidneys, pancreas)
intraperitoneal organs
encircled by peritoneum

cephalic
the head/towards the head
superior
at a higher level of the body
caudal
(coccyx in humans) the tailbone/towards the tailbone
inferior
at a lower level of the body
medial
towards the center of the body on a longitudinal axis; towards the midsagittal plane
lateral
away from the center of the body on a longitudinal axis; away from the midsagittal plane
