Week 11: Small Animal Abdomen Part 1 Flashcards
Mesenteries
Double layers of peritoneum that connect viscera to dorsal and ventral body wall
6 dorsal mesentaries
- Greater omentum
- Mesoduodenum
- Mesentary
- Mesocolon
- Mesorectum
- Lateral ligaments of urinary bladder
3 ventral mesentaries
- Falciform ligament
- Lesser omentum
- Median ligament of the urinary bladder
Superficial and deep leaves of the omentum enclose a space called
omental bursa
Three parts of the GI tract
- Stomach
- Small intestine
- Large intestine
Accessory organs of digestion
Liver
Gall bladder
Pancreas
Large intestine is divided into
- Cecum
- Ascending colon
- Transverse colon
- Descending colon
Immune organ
Spleen
Endocrine organs
- Adrenal glands
- Pancreas
Urinary organs
- Kidneys
- Ureters
- Bladder
Attachment of the superficial leaf of the greater omentum
Greater curvature of the stomach
Attachment of the lesser omentum
Lesser curvature of the stomach
Three parts of the pyloric region of the stomach
- Pyloric antrum
- Pyloric canal
- Pylorus (sphincter)
Gastric dilation-volvulus
- Condition in dogs
- Usually in large breeds
- Excessive dilation of the stomach, followed by twisting along it’s longitudinal axis
Root of the mesentery contains
- Cranial mesenteric artery
- “The mesentery”
Tranverse colon is located ___ to root of mesentary
cranial
Caudal duodenal flexure is located _____ to the root of the mesentary
caudal
Cranial duodenal flexure and descending duodenum is on the
right
Ascending duodenum is on the
left
Ascending duodenum is connected to the colon via
The duodenocolic fold
Junction between the duodenum and the jejunum
Duodenojejunal flexure
Jejunum is suspended within
The mesojejunum of the mesentary
Ileum opens into the ascending colon through the
ileocolic orifice
Cecum and ascending colon in the dog communicate via
The cecocolic orifice
There is no ileocecal orifice in the dog
The descending colon transitions into the rectum within
The pelvic canal
Lobes of the liver
- 6
- Left lateral
- Left medial
- Quadrate
- Right medial
- Right lateral
- Caudate (caudate and papillary surface)
Porta of the liver is located
Between the caudate and papillary processes of the caudate lobe
Papillary processes of the liver nestles in
The lesser curvature of the stomach
Gall bladder is located
Between right medial and quadrate lobes
Purpose of gall bladder
Stores bile produces in the liver
Hepatic ducts
Transport bile from liver lobes to bile duct
Cystic duct
- Extends from neck of gall bladder
- Two way passage for bile to/from gall bladder
Bile duct joins ___ ___ and both open…
- Pancreatic duct
- Through major duodenal papilla within the initial portion of duodenum
Parts of pancreas
- Right lobe
- Body
- Left lobe
Right lobe of pancreas is within the
Mesoduodenum
Left lobe of pancreas is within
the deep leaf of the greater omentum
Pancreas has both (functions)
Exocrine and endocrine functions
Three structures that enter and leave each kidney at the hilus
- Renal artery
- Renal vein
- Ureter
Vaginal ring
Region where an extension of the peritoneum protrudes through the deep inguinal rng
