Q

what is the foramen cecum remnant of

A

the thyroglossal duct which the thyroid gland developed from

18
Q

what marks the midline of the inferior surface of the tongue

A

the frenulum

19
Q

what is found on either side of the frenulum

A

lingual vein and sublingual folds

20
Q

what are two examples of veins of the tongue

A

deep lingual vein and dorsal vein

21
Q

what are the four intrinsic muscles of the tongue

A

superior longitudinal. inferior longitudinal, transverse and vertical

22
Q

what is the function of the superior and inferior longitudinal muscles

A

makes tongue short and thick

23
Q

what is the function of the transverse and vertical muscles

A

makes tongue long and narrow

24
Q

what are the four extrinsic muscles

A

genioglossus, hyoglossus, palatoglossus and styloglossus

25
Q

what is the function of the genioglossus

A

responsible for protruding the tongue

26
Q

where is the genioglossus situated

A

superior to the mylohyoid and geniohyoid muscles, attaching to the hyoid and superior mental spines of the mandible

27
Q

what occurs if the genioglossus is not working and when might this occur

A

the tongue falls posteriorly and obstructs airway - this can happen during general anaesthesia

28
Q

where is the hyoglossus muscle situated

A

lateral to genioglossus

29
Q

what is the function of the hyoglossus

A

depressing the sides of the tongue

30
Q

what major structure of the tongue passes between the hyoglossus and genioglossus muscles

A

the lingual artery

31
Q

what is the function of the styloglossus muscle

A

elevating and retracting the mandible

32
Q

where is the palatoglossus muscle situated

A

it originates from palatine aponeurosis on posterior surface of hard palate

33
Q

what is the function of the palatoglossus

A

depresses soft palate towards the tongue
can lift the posterior tongue

34
Q

what nerve supplies all the muscles of the tongue except from the palatoglossus

A

hypoglossal nerve

35
Q

what supplies the palatoglossus muscle

A

the vagus nerve (CN X) via pharyngeal nerves

36
Q

what supplies general sensation to anterior 2/3rd of tongue

A

CN V3 - lingual nerve

37
Q

what supplies general sensation to the posterior 1/3rd of tongue

A

glossopharyngeal nerve (CN IX)

38
Q

what supplies special sensation to anterior 2/3rds of tongue

A

chorda tympani via facial nerve (CN VII)

39
Q

what supplies special sensation to posterior 1/3rd of tongue and the vallate papillae

A

glossopharyngeal nerve (CN IX)

40
Q

what is the arterial supply of the tongue

A

lingual artery via the external carotid

41
Q

what is the venous drainage of the tongue

A

the deep lingual and dorsal lingual veins that drain into the IJV either directly or via lingual vein
