Q

how is the tongue compartmentalised

A

The anterior and posterior parts of the tongue are separated by the terminal sulcus

posterior part = forms anterior wall of oropharynx

23
Q

how is the tongue compartmentalised

A

The anterior and posterior parts of the tongue are separated by the terminal sulcus

posterior part = forms anterior wall of oropharynx

24
Q

what are the lymphoid nodules found in the posterior tongue

A

lingual tonsil

25
Q

what features are found on the anterior part of the tongue

A

covered in numerous small lingual papillae
(vallate, fungiform, filiform, foliate)

26
Q

what features are on the inferior surface of the tongue

A

frenulum
sublingual caruncle(papilla)
openings of submandibular and sublingual ducts

27
Q

what are the intrinsic muscles of the tongue

A

Superior longitudinal
Vertical
Transverse
Inferior longitudinal

28
Q

what are the extrinsic muscles of the tongue

A

Palatoglossus
Styloglossus
Hyoglossus
Genioglossus

29
Q

where does the lingual artery enter the tongue

A

between the hyoglossus and genioglossus muscles

30
Q

where do the hypoglossal and lingual nerves enter the tongue

A

external surface of the hypoglossus

31
Q

motor innervation of the tongue

A

Hypoglossal nerve (CNXII)

EXCEPT palatoglossus muscle which is supplied by the CN X vagus

32
Q

general sensation of tongue supplied by

A

ANT 2/3 - Mandibular (trigeminal CNV3)

POST 1/3 - glossopharyngeal (CN IX)

33
Q

special sensation (taste) of tongue supplied by

A

ANT 2/3 – Facial nerve via chordae tympani
POST 1/3 – Glossopharyngeal nerve

34
Q

arterial supply of the tongue

A

lingual artery (from ECA)

35
Q

venous drainage of the tongue

A

The deep lingual and dorsal lingual veins drain (into IJV)

36
Q

where does the submandibular gland lie

A

along the mandible
wraps around the mylohyoid
Deep part lies in the floor of the oral cavity, lateral to the root of the tongue

37
Q

where are the submandibular ducts

A

5cm long
open into 3 orifices in oral cavity - sublingual caruncles/papilla

38
Q

what is the arterial supply/venous drainage to the submandibular gland

A

submental artery/vein

39
Q

where does the sublingual gland lie

A

Sits in sublingual fossa of mandible, superior to anterior part of the mylohyoid line

40
Q

blood supply to sublingual gland

A

via submental & sublingual arteries (branch of facial & lingual arteries)

41
Q

venous drainage of sublingual gland

A

via submental veins (to lingual & facial veins)

42
Q

where are the sublingual ducts

A

there are many and they open at the crest of sublingual folds in oral cavity

43
Q

what is the PARASYMPATHETIC secretomotor innervation of the submandibular and sublingual

A

Parasympathetic (to produce saliva)
1. Preganglionic -fibres travel to the submandibular ganglion from the chorda tympani via the lingual nerve (CN V3)
2. postganglionic - fibres travel in the lingual nerve (CN V3) to the sublingual gland OR travel directly to the sublingual & submandibular glands

44
Q

what is the SYMPATHETIC innervation of the submandibular and sublingual

A

innervation from the superior cervical ganglia & the nerve plexus on the ECA

Vasoconstriction & reduction in volume of saliva that leads to dry mouth

45
Q

what are the minor salivary glands

A

Buccal (cheek)
Palatine (palate)
Lingual (tongue)
Labial (lip)
(embedded in submucosa in oral cavity)

46
Q

what is the innervation of minor salivary glands

A

CN VII & CN V

47
Q

what is the relationship b/w submandibular and sublingual

A

Thenerves of the sublingual glandsaccompany those of the submandibular gland

48
Q

Minor Salivary Gland Innervation (parasympathetic) ABOVE ORAL FISSURE

A

PARASYMPATHETIC innervation
Preganglionic - fibres travel to the pterygopalatine ganglion in the greater petrosal nerve (CN VII nervus intermedius)

Postganglionic -mfibres travel to the palate via the palatine nerves

49
Q

Minor Salivary Gland Innervation (parasympathetic) BELOW ORAL FISSURE

A

PARASYMPATHETIC
Preganglionic - fibres travel to the submandibular ganglion from the chorda tympani (CN VII nervus intermedius) & via the lingual nerve (CN V3)

Postganglionic - fibres then travel in the lingual nerve (CN V3) to the glands OR travel directly to the glands not in a nerve

50
Q

common pathologies associated with the salivary glands

A

mumps - viral infection - swellings
salivary stones (sialolithiasis) - pain, swelling & lack of salivation -
Excessive salivation (ptyalism) - Commonly occurs prior to vomiting - assoc/ with several disease processes

51
Q

contents of the submandibular triangle

A

submandibular gland
lymph nodes
(parts of) hypoglossal nerve
mylohyoid nerve & parts of the facial artery & vein
part of digastric

52
Q

contents of the submental triangle

A

submental lymph nodes & some small veins

53
Q

contents of the carotid triangle

A

(among other structures) carotid sheath and contents; external carotid and some branches; parts of accessory & hypoglossal nerves; deep cervical lymph nodes

54
Q

what is the arterial supply to the upper and lower lip

A

ECA via facial artery
superior (upper) and inferior (lower) labial arteries
