RUMINANT\PIG ABDOMEN2 CORRECT
DETAILED ANSWERS.
In the ruminant, the lesser omentum arises from the _______ to the
_______ - CORRECT ANSWER -Lesser curvature of the abomasum to the
visceral surface of the Liver
What is a major function of the Omentum? - CORRECT ANSWER -Also referred
to as the "Policeman" of the Abdomen, the omentum will fuse with the
peritoneum surrounding an infection in order to limit its spread to the
surrounding viscera
Which part of the ruminant stomach is its most cranial segment? - CORRECT
ANSWER -Reticulum
What is the name of the Reticulum's free ventral part? - CORRECT ANSWER -
Fundus
What are the three segments of the Gastric groove, linking the forestomach
to the glandular stomach? - CORRECT ANSWER -1. Reticular groove
2. Omasal groove
3. Abomasal groove
What is another name for the mucosa that are thrown into the
"honeycomb-like" structured folds of the Reticulum? - CORRECT ANSWER -
Reticular cells
, What structures found within the reticulum increase their surface area for
absorption? - CORRECT ANSWER -Papillae reticuli (conical reticular papillae)
What term refers to the structure that provides a direct route running from
the cardia to the pylorus of the abomasum? - CORRECT ANSWER -Gastric
groove
In an adult ruminant, a bolus will fall from the cardia into which region of
the forestomach? - CORRECT ANSWER -Atrium ruminis
The reticular groove extends ventrally from the _____ of the lesser
curvature to the _____ - CORRECT ANSWER -From the cardia of the lesser
curvature to the reticulo-omasal orifice
What structures of the reticular groove form the tube/tunnel that bypasses
the rumen, reticulum and omasum? - CORRECT ANSWER -Cranial and Caudal
lips
Typically adult ruminants lose the neurohumoral stimulation of the gastric
groove; however, doctors have learned to iatrogenically control this reflex
by administering .... - CORRECT ANSWER -- Copper sulfate solutions in sheep
- 10% sodium bicarbonate in cattle
What is the clinical relevance of iatrogenic control of the gastric groove in
adult ruminants? - CORRECT ANSWER -This may be exploited to administer
drugs that need to bypass the forestomach, to avoid destruction or dilution
