lesson 2 body cavities

dorsal cavity subdivisions

cranial and spinal cavity

meninges

membranous layers lining dorsal body cavity

what organs does the cranial cavity contain

brain

what does the verterbral cavity contain

spinal cord

what are the two major ventral cavity subdivisions

thoracic and abdominopelvic cavity

what are the thoracic cavity subdivisions

two pleura cavities, mediastinum, and pericardial cavity

the thoracic cavity has a mid portion called the

mediastinum

what does the mediastinum contain

heart, thymus gland, trachea, esophagus

what is the left and right side of mediastinum called

pleural cavities, they house the lungs

pericardium

covers the heart

parietal pericardium

“outer wall” of the pericardium, surrounding the mediastinum

visceral pericardium

“inner wall” of the pericardium, covers the surface of the heart

What is the fluid filled cavity between the parietal pericardium and the visceral pericardium called

pericardial cavity

What can the term pleural cavity refer to

the entire space to the side of the mediastinum or to just the potential space left surrounding the lung between the parietal and visceral pleura 

parietal pleura

lines the thoracic wall, “outer wall” of the pleura

visceral pleura

covers surface of the lungs, “inner wall” of the pleura

What is the fluid filled cavity between the parietal pleura and the visceral pleura called

pleural cavity

abdominopelvic cavity subdivisions

 has an upper portion called the abdominal cavity and a lower portion called the pelvic cavity

what does the abdominal cavity contain

stomach, intestines, spleen, liver

What does the pelvic cavity contain

urinary bladder, reproductive organs, rectum

serous membranes

Thin, double-layered membrane separated by serous fluid

parietal peritoneum

lines the abdominopelvic walls, “outer layer” of the peritoneum

visceral peritoneum

“inner wall” of the abdominopelvic cavity

peritoneal cavity

What is the fluid filled cavity between the parietal peritoneum and the visceral peritoneum called

How is the abdominopelvic region split

It is split into four quadrants. it is split with a midsagittal and transverse plane right through the navel(umbilicus)

A more precise way that the abdominopelvic region is splitting it into 9 regions: what are they?

right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right iliac, hypogastric, left iliac

right hypochondriac region

Right portion of the liver, gallbladder, and right kidney

epigastric region

majority of the stomach, part of the liver and pancreas. 

left hypochondriac region

part of the spleen, left kidney, part of the stomach, and pancreas

right lumbar (flank) region

Right kidney, parts of the colon, and ascending colon

umbilical region

Duodenum, small intestine, and transverse colon

left lumbar (frank) region

Left kidney, descending colon, and parts of the small intestine

right iliac (inguinal region)

Appendix, cecum, ascending colon, and small intestine. 

hypogastric (pubic) region

bladder, parts of the sigmoid colon, and reproductive organs

left iliac (inguinal region)

descending colon, sigmoid colon, and small intestine

organs of the RUQ

liver, colon, gallbladder, small intestine, pancreas, large intestine, lungs

organs of the LUQ

small intestine, spleen, stomach, pancreas, liver, large intestine, lungs

organs of the RLQ

small intestine, appendix, large intestine, reproductive organs

organs of the LLQ

small intestine, large intestine, reproductive organs

what does hypochondriac mean

 “under cartilage” referring to rib cartilage

what does epigastric mean

upon (around) the stomach

what does iliac mean

ileum:  lowest part of the small intestine

what does hypogastric mean

below the stomach

what is apart of the axial portion of the body

head, neck, trunk, torso

appendicular portion of the body

upper and lower extremities and their connections to the axial portion

what is the torso composed of

 thoracic, abdominal, and pelvic areas

what is serous membranes

 A thin lining of closed cavities in the body

examples of serous membranes

pericardium and pleura 

lumen

cavity or open channel within a tubular organ

central

closer to center of body

peripheral

away from the center of the body

medullary

inner/central region of an organ

cortical

outer layer of organ

basal

towards the base

apical

towards the apex/tip
