where is the parotid papilla located

26
where is the parotid papilla located
They are located opposite the second maxillary molar
27
frenum
narrow band of tissue that connects 2 structures
28
the labial frenum passes from the midline of the max and mand. arch to the...
inner surface of the lip
29
buccal frenum passes from the oral mucosa near the max and mand first molars to the
inner surface of the cheek
30
gingivae aka
gums
31
gingivae are
masticatory mucosa that cover the alveolar processes of the jaws and surround the necks of the teeth
32
what role do the gums play in oral health
surround the tooth like a collar and are self cleaning
33
normal gingiva
firm and resistant and tightly adapted to the tooth and bone
34
the surface color of gingiva....
varies due to the individuals pigmentation
35
the surfaces of the attached gingiva and interdental papilla are...
stippled and similar in appearance to an orange
36
Sometimes the gingivae do not completely cover the roots of the teeth and the roots become
exposed
37
gingival recession
can lead to sensitivity and root cavities
38
Why does the color of gingivae vary?
In dark-skinned people, the gingivae may contain more melanin pigment than the nearby alveolar mucosa does
39
This melanin pigment is synthesized in specialized cells and is produced as granules ...
that are stored within the cells that produce melanin
40
unattached gingiva aka
free gingiva or marginal gingiva
41
unattached gingiva
is the the border of the gingiva surrounding the teeth in collar-like fashion
42
unattached gingiva consists of the tissues ...
from the top of the gingival margin to the base of the gingival sulcus
43
what is 1mm wife and forms the soft wall of the gingival sulcus
unattached gingiva
44
gingivits
unattached gingiva is the 1st tissue to become inflamed
45
interdental gingiva aka
gingival papilla
46
interdental gingiva
Extension of the free gingiva that fills the interproximal embrasure between two adjacent teeth
47
gingival groove
a shallow groove that runs parallel to the margin of the unattached gingiva and marks the beginning of the attached gingiva
48
attached gingiva
extends from the base of the sulcus to the mucogingival junction
49
oral cavity proper
are inside the dental arched
50
in the back of the last molar on each side is a space that links the vestibule and...
oral cavity proper
51
the difference between the oral cavity proper and vestibules
The vestibule is the space between the teeth and the inner mucosal lining of the lips and cheeks , and the oral cavity proper is the space on the tongue side within the upper and lower dental arches
52
hard palate
separates the nasal cavity above from the oral cavity below
53
The nasal surfaces are covered with
respiratory mucosa
54
oral surfaces are covered with
oral mucosa
55
The mucosa of the hard palate is tightly bound to the underlying bone, and therefore ....
submucosal injections into the palatal area can be extremely painful
56
hard palate aka
roof of the mouth
57
incisive papilla
pear-shaped pad of tissue that covers the incisive foramen
58
palatal rugae
irregular ridges of masticatory mucosa extending laterally from the incisive papilla
59
palatine raphe
runs posteriorly from the incisive papilla at the midline
60
palatal glands
numerous small glands that open onto the palatal mucosa as small pits
61
the incisive papilla are
easily burned with hot food and drinks
62
it is the landmark for the dentist to...
give a palatal injection of local anesthesia to numb the soft tissue of the hard palate.
63
The soft palate is the
movable posterior third of the palate
64
The soft palate has no
bony skeleton and hangs like a limp curtain into the pharynx behind i
65
The soft palate ends
posteriorly as a free edge with a hanging projection called the uvula
66
The soft palate is supported posteriorly
by two arches, the fauces
67
The anterior arch runs from the
soft palate down to the lateral aspects of the tongue as the palatoglossal arch
68
The posterior arch, the free posterior border of the soft palate, is called the
palatopharyngeal arch
69
The opening between the two arches is called the
isthmus of fauces
70
The opening between the two arches is called the isthmus of fauces and contains the
palatine tonsil
71
How does the soft palate differ from the hard palate?
the soft palate is movable
72
The tongue is an important organ, responsible for several functions
``` Speech Manipulation and positioning of food Sense of taste Swallowing Cleansing of the oral cavity ```
73
The tongue is an important organ, responsible for several functions
``` Speech Manipulation and positioning of food Sense of taste Swallowing Cleansing of the oral cavity ```
74
What is the term for the upper surface of the tongue?
It is covered on top with a thick layer of mucous membrane and thousands of tiny projections called papillae
75
body
anterior two thirds of the tongue
76
root
posterior portion that turns downward toward the pharynx
77
dorsum
upper and posterior roughened surface
78
sublingual surface
covered with smooth, transparent mucosa
79
lingual frenulum
a thin fold of mucous membrane that extends from the floor of the mouth to the underside of the tongue
80
Name a common location for oral cancer
root of the tongue
81
What is another name for the underside of the tongue?
ventral surface
82
Why does the dorsum of the tongue feel rough?
The dorsum comprises the superior [upper] and posterior roughened aspects of the tongue
83
The submandibular ducts are located at
either side of the lingual frenulum.
84
Taste Buds
Located on the fungiform papillae and in the trough of the large vallate papillae,
85
Taste Buds
The sense of touch is provided by numerous filiform papillae that cover the entire surface of the tongue
86
Which kind of papillae do not contain taste receptors?
Filiform papillae do not contain taste receptors
