Q

Oral cavity is separated by what ?

A

by upper and lower dental arches
Oral vestibule – Between dental arches and cheeks + lips
Oral cavity proper – enclosed by dental arches

19
Q

Separation of upper and lower dental arches is dependant on the elevation/depression of the mandible at the

A

Temporomandibular joint.

20
Q

Oropharyngeal isthmus can be closed/opened by surrounding. ………….

A

tissues including tongue and soft palate.

21
Q

oral cavity functions as what structure———–for digestive system?

A

inlet

22
Q

Oral cavity allows…………

A

which allows for initial processing of food, as well as manipulating sounds that are produced by the larynx

23
Q

Hard Palate

A

anterior, bony plate, continues as soft palate posteriorly.

24
Q

soft palate functions as ?

A

valve

Depression helps close the oropharyngeal isthmus
Elevation separates nasopharynx from oropharynx

Soft palate formed and moved by four muscles

25
Q

a small muscular projection hanging from the posterior free margin of the soft palate

A

UVULA

26
Q

Floor of oral cavity proper is formed by:

A

1, Mylohyoid muscle
2.the tongue
3. 2 geniohyoid muscles

Floor of oral cavity proper is formed by:
Muscular diaphragm, which fills the U-shaped gap between left and right side of body of mandible. This muscular diaphragm is formed by the pair of mylohyoid muscles
Two cord-like geniohyoid muscles above the diaphragm
The tongue

27
Q

Structure composed of fascia and a layer of skeletal muscle sandwiched between skin externally and oral mucosa internally?

A

Cheeks

28
Q

Buccinator – skeletal muscle within the cheek

A

Pterygomandibular raphe joins posterior margin of buccinator and anterior margin of superior pharyngeal constrictor – creating continuity between oral and pharyngeal cavities.

Modiolus – Nodule of connective tissue, acts as insertion point of buccinator, supporting the muscles of the lips and cheeks

29
Q

general sensory innervation to oral cavity for the upper and lower parts are ?

A

from trigeminal nerve

upper - maxillary nerve, CNV2
lower-mandibular nerve, CNV3

30
Q

Taste special afferent sensation that is found anterior two-third of tounge?

A

the facial nerve, CNVII: branches join and distributed among CNV

31
Q

Parasympathetic innervation to glands is ?

A

Facial nerve, CNVII: distributed by CNV.

32
Q

Sympathetic innervation to the glands is ?

A

T1 spinal nerve fibers which synapse in the superior cervical ganglion.

33
Q

Where does the tongue lie?

A

anterior in the oral cavity

34
Q

Apex of tongue directed ………………y, lies immediately behind…………?

A

anteriorly
incisor teeth.

35
Q

The root of the tongue is attached to which bones?

A

Mandible and hyoid bones

36
Q

what separate the oral and pharngeal surfaces of the tongue

A

V-shaped terminal sulcus of the tongue

37
Q

a small depression at the apex of the terminal sulcus that marks site in embryo where epithelium invaginated to form thyroid gland.

A

Foramen cecum.

38
Q

The superior surface of the tongue is covered with hundred of ?

A

papillae

39
Q

FILIFORM PAPILLAE

A

Small cone-shaped projections that end in one or more points.

40
Q

vallate papillae

A

largest blust ended cylindrical papillae,8-12 papillae in a single V-shaped, immediately anterior to terminal sulcus.

41
Q

foliate papillae

A

linear folds on the sides of the tongue near the terminal sulcus

42
Q

The inferior surface of the tongue?

A

lacks papillae
number of linear mucosal folds
single median fold- Frenulum of the tongue, overlies the lower margin of the midline septum

43
Q

On each side of the frenulum lies what vein ……………? and lateral to each vein is a

A

a) lingual vein

B) rough fimbriated fold
