Floor of the Mouth of Animals
Floor of the Mouth of Animals like ox, Sheep and Goat, Horse, Pig, Dog and Rabbit in this post.
Floor of the Mouth of Ox
The floor of the mouth of ox is free only in its cranial part and is formed by the body of the mandible covered by mucous membrane. the attached portion of the tongue occupies the reminder of the floor.
About opposite to the corner tooth or slightly behind its level, papillae present – the caruncula sublingualis or barb. through which the ducts of the mandibular and ventral part of sublingual salivary glands open into the mouth.
The papilla is wide, hard and serrated. Just behind these papillae is a median fold of mucous membrane passing to ventral face of the tongue, this is called frenulum linguae.
A linear series of horny papillae are seen on the floor on either side of the frenulum linguae near which the ducts of the dorsal part of the sublingual salivary gland open.
Behind the last tooth a vertical fold of mucous membrane passes from the upper to the lower jaw, the plica pterygomandibularis that contains a ligament of the same name.
Floor of the Mouth of Sheep and Goat
Floor of the Mouth of Sheep and Goat is same as Ox.
Floor of the Mouth of Horse
The caruncula sublingualis is opposite the canine tooth and on it opens the mandibular duct.
From either side of the fraenum linguae and extending backward to the level of the lower 4th cheek tooth is a mucous fold – the sublingual fold, which covers the gland of the same name and presents numerous small papillae through which the ducts open. The linear series of papillae on the floor is absent in horse. The isthmus faucium is relatively small and not dilatable.
Floor of the Mouth of Pig
The frenulum linguae are double in Pig and there is a well–marked glosso-epiglottic fold, on either side of which is a depression.
Floor of the Mouth of Dog
Sublingual fold is present and it shows the openings of cranial part of the sublingual gland. Caruncula sublingualis is indistinct in Dog.
Floor of the Mouth of Rabbit
The duct of the infra orbital gland runs forward into the floor of the buccal cavity in Rabbit.
