How does the liver, gall blader and pancreas develop?

hepatic + dorsal pancreatic diverticulum

Vascularization of the 3 parts of the esophagus

cr + cd thyroid A
Bronchoesophageal A
left gastric A

What is and which organs are retroperitoneal organs?

no visceral peritoneum

- kidneys, adrenal gland, urethra, pancreas

Which species have a:
simple monogastric
conplex monogastric
polygastric

Car
Equine + Pig
Birds + Rum

What are the cr and cd surface of the monogastric called?

cr: parietal
cd: visceral

What opening do we find in the tegumentary mucosa of Eq

cardia

Which ligaments form the greater + lesser omentum

- gastrophrenic, gastrosplenic, phrenicoplenic | - hepatogastric, hepatoduodenal

Vascularization of monogastric stomach

celiac A

How do we call the cranial part of the rumen?

The atrium

Where does the esophagus open in RUM

Cardia is at the cr-ds part of rumen

Where does the greater omenutm attach in RUM

left long groove

what are pillars of the stomach in RUM

inside folds from the grooves

Which stomach in RUM have the honeycomb papillae?

reticulum

What is the gastric groove?

in calfs, conection btw cardia and abomasum for the milk

Vascularization of the stomach of RUM

celiacomesenteric trunk

Location of the dif part of the esophagus

- cervical: ds - thoracic: left - abdominal: left (passes through the right crura

Which stomach in RUM absorbs, water, NA + fatty acids

reticulum

What are the 2 oral vestibule

- labial | - buccal

Why is the buccinator muscles more developed in some species

- Eq: grasping food | - Mammals: sucking milk when youngs

What are the 2 arches made by the soft palate laterally?

- palatoglossus | - palatopharyngeal

What is the structure of a tooth

- crown: clinical vs anatomical - neck - root - cementum - enamel - dentin - pulp cavity (vessels + nerves) - periodontal lig

Where does each salivary gland drain their product

- parotid: 4th premolar - mandibular + monostomatic sublingual: sublingual caruncles - polystomatic sublingual: floor or oral cavity

What are the guttural pouches?

- in horses, evagination of the vt part of the eustechian tube forming air chambers. No real function

What are the structures that develop from the midgut and foregut

- midgut: part of duodeneum, jejunum, ileum, ceacum, ascending colon, 1/2 transverse colon - hindgut: 1/2 transverse colon, descending colon, anus, rectum, urogenital sinus (urethra + urinary bladder)

Explain the 5 common digestive system, congenital disorders.

- stenosis - atresia (anals vs rectal) - fistula (rectovesical, rectovestibular, rectourethral) - umbilical hernia - megaesophagus, megacolon

Explain the dif areas of stenosis in the esophagus.

- entrance of thoracic cavity - at base of heart - at esophagal hiatus in the diaphragm (right crura)

What are the dif parts of the tegumentary mucosa in Equine

- cardic - fundic (reddest) - pyloric

What are the ligaments forming the greater and lesser omentum?

- gastrophrenic, gastrosplenic, phrenicosplenic | - haptogastric, haptoduodenal

Where would we do a surgery on the stomach?

on the middle part of the visceral or parietal surface (not at the curvatures due to the minor and major vascular circles of the stomach)

What does the portal vein contain and where does it go?

- de 02 blood but high in nutrients | - goes to the liver
