3 - Digestive System

• upper lip is pendulous and presses on the lower one


  dog
• an advantage in administering liquid medicines

  large vestibule
• The general looseness of the lips creates a

  large vestibule- an advantage in administering liquid medicines. Upper lip has philtrum


  dog
• lips are less mobile and reduced

  cat
• less mobile; upper lip blends with nose to form nasolabial plate (muzzle) which is moist and glandular


  cattle
• In cattle, lips are less mobile; upper lip blends with nose to form _____ which is moist and glandular

  nasolabial plate (muzzle)
• soft and flexible and aid in picking up food; upper lip is deeply grooved with a midline philtrum

  sheep
• mobile upper lip, used for collecting food and introducing it to the mouth. The lips are sensitive


  horse
• less mobile; upper lip blends with the nose to form rostrum (snout),which contains the bone, os rostrale, lower lip is noticeably smaller than the upper lip

  pig
• The pig's lips are less mobile; upper lip blends with the nose to form ______

  rostrum (snout)
• lip is absent. Has beak used for prehension and for aerodynamics

  bird
• It is the modificication of the jaw of bird and used for prehension and for aerodynamics

  beak
• Beak also serves as a ____

  sense organ (bill tip organ)
• serves as a sense organ (bill tip organ) via sensory corpuscles (touch papillae)

  embedded in the keratinised tissue of the beak and associated lamellae


  beak
• have pointed beak


  gallinaceous birds
• have a flattened, spoon-shaped beak that is somewhat more

  flexible and is adapted for straining through water for foodstuffs

  Anseriformes
• widest at the 4th cheek tooth and median raphé usually replaced by a ridge

  hard palate of dog
• widest at the 4th cheek tooth and median raphé usually replaced by a

  ridge
• cranial portion forms the prominent dental pad.


  ruminant
• The rugae extend only 2/3 of the length of the palate and all but the last few are serrated on their free borders


  ruminant
• In hard palate of the ruminant, cranial portion forms the prominent _____

  dental pad
• In hard palate of the ruminant, the rugae extend only ____ and all but the last few are serrated on their free borders

  2/3 of the length of the palate
• the rugae are not serrated

  hard palate of sheep
• The openings of the naso-palatine ducts form a prominent V

  on either side of the central incisive papilla


  hard palate of sheep
• divided into two equal portions by the median raphe and the palatine rugae extend the

  whole length of the palate

  hard palate of horse
• hard palate of horse divided into two equal portions by the _____ and ____

  median raphe and palatine rugae extend the whole length of the palate
• has long and narrow hard palate with equal width throughout.

  hard palate of pig
• Both rugae and median

  raphé are well marked. Incisive papilla is prominent anteriorly

  hard palate of pig
• lacks soft palate


  hard palate of chicken
• Wide, thin and mobile


  dog
• dorsum marked by median groove; long backward pointing papillae on the

  root; inferior part of the tip has cord of fibrous tissue— the lyssa


  dog
• In tounge of dog, dorsum marked by ____

  median groove
• inferior part of the tip has cord of fibrous tissue

  lyssa
• Posterior half of dorsum is prominent bulge, torus linguae, and marked off by transverse depression,

  transverse lingual fossa

  cattle
• Papillae on the torus lingua are distinct and are termed conical papillae


  cattle
• In cattle, posterior half of dorsum is prominent bulge, _____

  torus linguae
• In cattle, posterior half of dorsum is prominent bulge, torus linguae, and marked off by transverse depression,

  transverse lingual fossa
• In cattle, papillae on the torus lingua are distinct and are termed

  conical papillae
• As in bovine but tip is more blunt and posterior prominence is not so well-marked.

  Sheep
• No conical

  papillae but less keratinized filiform papillae are numerous at the tip.
