25
what is the function of the superior longitudinal muscle?
moves tip of tongue superiorly
26
what is the function of the vertical muscle?
broadens the tongue
27
what is the function of the transverse muscle?
narrows tongue
28
what is the function of the inferior longitudinal muscle?
moves the tip inferiorly
29
what is the function of the genioglossus muscle?
protrudes and depresses tongue
30
what is the function of the hyoglossus muscle?
depresses lateral aspect of the tongue
31
what is the function of the styloglossus muscle?
elevates the posterior aspect and retrudes tongue
32
what is the function of the palatoglossus muscle?
elevates posterior tongue to close the fauces
33
All tongue muscles are innervated by hypoglossal nerve except for
palatoglossus which is innervated by vagus nerve (through pharyngeal plexus)
34
what is the role of the mylohyoid and geniohyoid in tongue movement?
support the tongue but aren't in the tongue
35
which muscles are involved with producing the d in bleed
genioglossal
36
which muscles are involved with producing k in make
palatoglossal and styloglossal
37
which muscles are involved with producing th in thing
genioglossal
38
Describe the innervation of the general sensation on anterior 2/3
lingual nerve
39
Describe the innervation of the general sensation and taste of the posterior 1/3
glossopharyngeal nerve
40
describe the innervation of taste sensation
chorda tympani branch of facial nerve on anterior 2/3
41
describe the innervation of pharyngeal plexus (vagus)
palatoglossus muscle
42
the parts of the epiglottis are
lateral glossoepiglottic folds, median glossoepiglottic folds and vallecula
43
what are the parts of the epiglottis innervated by?
Vagus Nerve
44
The hypoglossal nerve is the main motor nerve and crosses the
lingual artery
45
which nerve in the tongue is most superior
lingual, with chorda tympani attached posteriorly, followed by glossopharyngeal, and hypoglossal
46
What is the arterial supply of the tongue
lingual artery from external carotid
47
what structure does the hypoglossal nerve cross
the loop of the lingual artery
48
The lingual vein runs parallel to
the branches of the lingual artery
49
the lingual vein drains into the
internal jugular vein
50
the jugulo-digastric is the
principal node of the tongue
51
which lymp is located near the hyoid bone
jugulo-omohyoid
52
which lymphs drain into the deep cervical nodes
submandibular and submental
53
all lymph drains into via lymph nodes into
deep vessels in the neck
54
the submental node drains
tip of the tongue
55
the submandibular nodes drain
central area of dorsum of tongue
56
the deep cervical chain is made up of
jugulodigastric and jugulo omohyoid
57
sulcus terminalis is
what separates anterior 2/3 and posterior 1/3
58
the surface projections on the mucous membrane are called
lingual papillae
59
the posterior 1/3 surface projections on the mucous membrane is forned by
lingual tonsils
60
The papillae anterior to the sulcus terminalis
circumvallate, fungiform papillae, filiform papillae, foliate papillae
61
which papillae have taste buds
circumvallate and fungiform
62
Barrel shaped epithelial structures are
a collection of fusiform cells that open into a gustatory pore
63
the main taste bud cell types are
gustatory, basal, supporting cells
64
the big white slices are called
crypt
65
crypt means that we are looking at
circumvallate papillae
66
a rich layer of keratin is seen on
filiform papillae
67
if there is no keratin it is
fungiform papillae
68
if filiform papillae is on the slide you call it
stratified squamous with keratinized tips
69
what do von ebner glands do
open into the bottom of the crypt to wash out the food
70
the core of the fungiform and filiform and circumvallate papillae is
lamina propria
71
the posterior 1/3 is lined by
stratified squamous non-keratinized epithelium
72
presence of lymphoid tissue in the form of lymphoid follicles is
lingual tonsil
73
epithelial crypts penetrate
the lingual tonsil
74
the posterior 1/3 mucous membrane is
stratified squamous non keratinized epithelium
75
the part of the lymphatic ring around the opening of the respiratory and digestive tract called
Waldeyers Ring
76
the lateral wall of the oropharynx is the
palatine tonsil
77
the lingual tonsil makes up
the posterior 1/3 of the tongue
78
the lymphoid organs on the nasopharynx is the
tubal tonsil and pharyngeal tonsil
79
all reticular connective tissue is filled with
lymphoid follicles
80
the lining of the oropharynx is
stratified squamous epithelium non keratinized
81
a lymphoid organ has a
capsule
82
the palatine tonsil has numerous lymphoid follicles
forming the parenchyma (framework made of reticular connective tissue)
83
the luminal surface epithelium is
stratified squamous epithelium non-keratinized
84
the presence of tonsillar crypts are
invaginations of epithelium
85
the hemicapsule is
a broken up capsule made of dense connective tissue
