peritoneum Flashcards
What is the peritoneum?
serous membrane that lines the the abdomiopelvic cavity
What are the parts of the peritoneum?
parietal peritoneum- loosely connected to the abdominopelvic wall
visceral peritoneum - lines viscera in abdominopelvic cavity
What does both peritoneum consist of?
mesothelium
what is the somatic innervation and vascularation of the parietal peritoneum?
Same that supplies the wall that overlies it
what is the innervation and vascularation of the visceral peritoneum?
same as the viscera it covers
What is the visceral peritoneum sensitive to?
Is insensitive to touch, cold, heat, and laceration.
Has no somatic afferents
What are the sensory pain fibers of the visceral peritoneum carried by?
Sensory pain fibers carried by thoracic and lumbar splanchnics
What does the visceral peritoneum also covers?
messenteries
What is the relationship of the viscera to the peritoneum cavity?
intraperitoneal
retroperitonel
secondarily retroperitoneal
What intraperitoneal viscera?
Covered almost completely with the visceral peritoneum
What is retroperitineal viscera?
Covered on one surface with visceral peritoneum.
what is secondarily retroperitoneal?
Organs that started out as intraperitoneal, but had a retroperitoneal position later in development.
What is the peritoneal cavity?
potential space that lies between the parietal and visceral layers of the peritoneum
What part of the embryo is the peritoneum a part of?
major part of the intraembryonic coelom.
how is the peritoneum attached to the extra embryonic ceolem?
Connected with the extraembryonic coelom at the umbilicus.
What is inside of the peritoneum cavity?
contains NO ORGANS but has peritoneal fluid which lubricates the surfaces.
contains leukocytes and antibodies that resist infection
in who is h peritoneal cavity connected?
females - connected by uterine tubes, uterine cavity, and vagina. potential of infection
completely closed in males
during development what does the intraembryonic ceoleom provide room for?
Intraembryonic coelom provides room for the intraabdominal organs to develop and move to their final positions.
during development what does the extra embryonic ceoleom allow for?
Extraembryonic coelom allows midgut herniation into the umbilical cord.
it is longer than the body so protrusion happens to give organs room to grow
