Small and large intestines and their suspension
Give the parts of the small intestines
- Duodenum
- Jejunum
- Ileum
Duodenum
From → to
Pylorus → jejunum
Give the parts of the duodenum
- Flexura duodeni cranialis
-
Duodenum descendens
- In contact with parietal peritoneum
- Runs caudally towards the right kidney
- Flexura duodeni caudalis
- Duodenum transversa
-
Duodenum ascendens
- Runs cranially
- Plica duodenocolica (ascending duodenum → descending duodenum)
-
Flexura duodenojejunalis
- Susupended by the mesoduodenum
- Originates from the dorsal abdominal wall
- Encloses right lobe of pancreas
- Susupended by the mesoduodenum
Pappilas of the dudoenum
-
Papilla duodeni major
- Bile duct and pancreatic duct
-
Papilla duodeni minor
- Accessory pancreatic duct
Give the parts of the pancreas
Two lobes:
-
Left lobe
- In bursa omentalis
- left + right pole
- In bursa omentalis
-
Right lobe
- In mesoduodenum
- Cranial + caudal pole
- In mesoduodenum
What is jejunum covered by
Omentum major
From which artery does jejunum receive nutrition?
A. mesenterica cranialis
What is jejunum suspended by
-
Mesojejunum
- From the dorsal abdominal wall
- At the ileocecal junction → continues with the descending mesocolon
What marks the position/length of ileum?
A. antimesenterica
What is localized between ileum and caecum?
Plica ileocolica
Fold between the ileum and the caecum
Give the parts of the large intestines
- Caecum
- Colon
- Rectum
What is the attachment between:
- Ileum to caecum
- caecum to colon
- Plica ileocaecale
- Plica caecocolica
Where does the caecum communicate with the ascending colon?
At the cecocolic orifice (ostium caecocolicum)
What is colon suspended by
Mesocolon
Give the parts of the colon
-
Colon ascendens
- Shortest
- Lies right to the root of the mesentery
- Flexura coli dextra
-
Colon transversus
- Right → left.
- Lies cranial to a. mesenterica cranialis
- Flexura coli sinistra
-
Colon descendens
- Longest, wider mesocolon
- Dorsal and left in abdomen
