Tongue

Question 1

Apex

Answer 1

Tip of tongue

Question 2

Body

Answer 2

Body of tongue

Question 3

Frenulum

Answer 3

Loose tissue connecting tongue to floor of mouth

Means little bridle/break, stops tongue from moving too far

Question 4

Torus (ruminants)

Answer 4

Raised part of caudal tongue. Mechanical aid.

Question 5

Lyssa and median sulcus (Raphe) (canine)

Answer 5

Lyssa is a rod of cartilage in the middle of the tongue.

Median sulcus is the longitudinal furrow on tongue.

Question 6

Ruminants: lingual fossa

Answer 6

Median of tongue, on rostral edge of torus. It is an indent in the tongue just showing the boundary of the apex of tongue and torus.

Question 7

Papillae: filiform, conical, lentiform, fungiform, vallate, foliate

Answer 7

Mechanical only:

Filiform: Located in rostral 2/3, soft to touch small

Conical: Located in caudal 1/3, larger, cornified in cat and bovine

Ruminants - Lentiform: Flattened filiform, on torus, have white ring around them?

Carry taste buds:

Fungiform: Mushroom like, scattered throughout

NOT ruminants - Foliate: Leaf like/book pages, lateral surface of caudal tongue

Vallate (means wall, they are crater-like): Large, circular, base of tongue

Question 8

Geniohyoideus muscle

Answer 8

Lies deep to mylohyoideus

Runs from: Intermandibular articulation to basihyoid

Function: Draws the hyoid apparatus and larynx rostrally

Question 9

Genioglossus muscle

Answer 9

Runs from: Medial surface of mantible to tongue

Pans the intermandibular space, arises as a thin sheet of transverse fibres from the medial surface of the mandible,

Function: Forms a sling that aids in support of the tongue

Question 10

Hyoglossus muscle

Answer 10

Runs from: Thyrohyoid and basihyoid bones to the root of tongue

it lies medial to the styloglossus

Function: Retracts and depresses the tongue

Question 11

Styloglossus muscle

Answer 11

Runs from: Stylohyoid bone to the middle of tongue

Function: Retract and elevate the tongue

Question 12

Mylohyoideus

Answer 12

Runs from: Medial surface of mandible to hyoid.
Forms a sling that aids in support of the tongue
