Inguinal canal and peritoneal cavity Flashcards
What structures are peritonea(immobile)l?
ascending and descending colon
kidney
What structures are in mesentery (mobile)?
small intestine sigmoid colon appendix transverse colon ileum
Where lies lesser sac?
Lesser sac lies in the space behind the stomach and in front of pancreas
Where lies lesser omentum?
It extends from the inferior border of the liver to the lesser curvature of the stomach (known as hepatogastric ligament) and from proximal part of the duodenum to the liver (known as the hepatoduodenal ligament)
Where lies greater omentum?
It is the largest peritoneal fold and arises from the greater curvature of the stomach. it hangs like an apron on intestines and is filled with fat.
it is infused with transverse colon.
What structures makes up portal triad?
Portal vein
Hepatic artery
Bile leaving the liver in the bile duct
What is porta hepatis?
Two major blood vessels enter the liver portal vein and hepatic artery
Where lies portal triad?
It runs in the free edge of the lesser omentum
What is the layout of the stomach?
oesophagus-stomach-duodenum-jejunum-ilieum-cecum-ascending colon-transverse colon-descending colon-sigmoid colon-rectum-anus
What nerves supply to diaphragm?
C3,4,5 spinal nerves
Which nerve supplies to parietal peritoneum?
peritoneum covering the inferior surface of diaphragm supplied by intercostal nerves peripherally and phrenic nerve C3,4,5 centrally
Parietal peritoneum in the pelvis is supplied by the obturator nerve
Which nerves supply to visceral peritoneum/
visceral does not have somatic innervation, so insensitive to pain
It receives sympathetic innervation and is sensitive to stretch, tension and ischemia
What 5 peritoneal fold on the abdominal wall?
Median umbilical fold, remnant of urachus (median umbilical ligament)
2 medial umbilical folds, containing remnants of umbilical arteries (MUL)
2 lateral umbilical folds, containing the inferior epigastric arteries
Where lies falciform ligament?
It is an anterior peritoneal fold lying between the diaphragm and the umbilicus which contains the ligamentum teres (a remnant of umbilical vein)
