PRESENTING PARTS

9. BASE OFTHE
TONGUE

10. DORSAL
SURFACE

11. -Vallate papillae
- Fungiform papillae
- Foliate papillae
- Filiform papillae.

13.  Frenulum linguae
 Plica fimbriata
 Deep lingual vein

15. Lateral margin

16. Root of theTongue

17.  Extrinsic muscles- alter the position of the
tongue
-Genioglossus
-Hyoglossus
(Chondroglossus)
-Styloglossus
-Palatoglossus

23. Styloglossus

25.  Superior longitudinal
 Inferior longitudinal
Intrinsic muscles- alter the shape of the tongue
•Transverse
•Vertical

26. Muscles altering the shape of the tongue
Making the dorsum concave-
Genioglossi, sup.long.muscles, verticalis and
styloglossi;
Making the dorsum convex-
Hyoglossi, inf.long.muscles, verticalis;
Muscles shortening the tongue-
Sup.and inf.long.muscles, verticalis;
Muscles elongating the tongue-
Transversus linguae.

27. Motor –
 Somatomotor -
all the muscles of the tongue are supplied by
hypoglossal nerve except palatoglossus cranial
part of accessory nerve through pharyngeal plexus
 Secreto-motor- to lingual glands- superior
salivatory nucleus-facial – chorda tympani and
lingual nerve- submandibular ganglion- lingual
nerve - glands
 Vasomotor- sympathetic nerves- superior
cervical ganglion- lingual artery.

28.  Sensory
1. Ant 2/3 – general – lingual nerve
special – chorda tympani nerve
(except vallate papillae)
2. Post 1/3 - general and special –
glossopharyngeal nerve
(including vallate papillae)
3. Posterior most
(Vallecula) – internal laryngeal nerve -
superior laryngeal nerve
vagus nerve

33.  LymphVessels do not accompany blood
vessels.
 Tip rich in lymph vessels.
 Free anastamosis between both sides.
 Cancer spread bilaterally to both side nodes.

34.  TongueTie
 BifidTongue
 LingualThyroid
 Thyro-glossal cyst
 Glossitis
 Carcinoma of theTongue
 Macroglossia
 Microglossia
 Aglossia
 Hemiglossia
