16
Q

cartilaje corniculate

A

la vafrul cartilajelor aritenoidiene

17
Q

cartilaje cuneiforme

A

plici ariteno-epiglotice

18
Q

cartilaje sesamoide

A

plici vocale

19
Q

muschii laringelui

A

striati
extrinseci si intrinseci

20
Q

muschi extrinseci

A

se insera cu un capat pe faringe si cu celalalt pe oragnele vecine
constrictor inf al faringelui -leaga cartilaje tiroid si cricoid de faringe
long sup al limbii - porneste de pe cartilaj epiglotic si patrunde in limba
palatofaringian - intra in valul palatin
stilofaringian - insertii inf pe cartilajr epiglotic,tiroid si cricoid
tirohioidian
sternotiroidian

21
Q

muschi extrinseci

A

se insera cu un capat pe faringe si cu celalalt pe oragnele vecine
constrictor inf al faringelui -leaga cartilaje tiroid si cricoid de faringe
long sup al limbii - porneste de pe cartilaj epiglotic si patrunde in limba
palatofaringian - intra in valul palatin
stilofaringian - insertii inf pe cartilajr epiglotic,tiroid si cricoid
tirohioidian
sternotiroidian

22
Q

muschii intrinseci

A

ambele capete inserate pe cartilaje ale laringelui
formeaza 3 grupe functionale
a - constrictori ai fantei glotice /adductori ai plicilor vocale
b - dilatatori ai fantei glotice abductori ai plicilor vocale
c- tensori ai plicilor vocale

23
Q

muschii constrictori ai fantei glotice

A

cricoaritenoidian
aritenoidian trnasvers
aritenoidian oblic
tiroaritenoidian
tiroepiglotic
ariepiglotic

24
Q

muschii dilatatori ai fantei glotice

A

cricoaritenoidian post - rol important in respiratie (paralizia lui face imposibila adductia corzilor vocale , fenomen insotit de dispnee sau chiar asfixie )

25
Q

muschii tensori ai plicilor vocale

A

vocal - sit in plica vocala
cricotiroidian - sit antlat de laringe

26
Q

tunica mucoasa

A

epiteliu + corion
continua mucoasa faringelui, se continua cu cea a traheei
epiteliu cilindric ciliat
la nivelul plici vocale - ep pluristratificat pavimentos
gl care secreta mucus
in corion-tesut limfoid - bogat la niv ventriculilor laringieni

27
Q

submucoasa

A

tesut conj lax

28
Q

confix interioara

A

3 etaje
supraglotic = vestibulul laringelui
glota
infraglotic =cav infraglotica

29
Q

glota

A

pereti lat - 2p de plici cu directie ant-post,
plici sup = plici vestibulare
intre plici - se delim fanta vestibulararima vestibulara
plici inf = plici vocale/coarde vocale

30
Q

intre plici vestibulare si vocale

A

ventriculii laringelui
prez o prelungire = saculet laringian - plin cu aer care intervine in modelarea timbrului sunetului laringian

31
Q

in timpul inspiratiei

A

plici vocale in abductie
fanta glotica larg deschisa
vizualizare cav infraglotica si primele inele traheale

32
Q

in timpul fonatiei

A

plicile vocale sea ting prim mag lor libere
fanta glotica - fisura liniara

33
Q

vascularizatie

A

art tiroidiana sup - art laringiana sup
art tiroidiana inf - art laringiana inf
vena laringiana sup - vena jug int

34
Q

limfaticele

A

grup sup - dren in noduri cervicale profunde
grup ant-inf - limfa glotei si a port ant- inf , dreneaza in noduri limfatice traheale si nodul prelaringian (Engel)
grup post-inf - in noduri limfatice traheale

35
Q

inervatie

A

somatomotoare, somatosenzitiva si vegetativa
nerg laringeu sup + inf+ vag

36
Q

nerv laringeu sup

A

se bifurca la nivelul hioidului
ram int -epiglota,vestibul laringian plica vestibulara - inerv senzitiva
ram ext - ventricul,plica vocala si cav infraglotica - inerv senzitiva
mucoasa laringelui si muschi tirocricoidian

37
Q

nerv laringeu inf

A

nerv lar recurent
ram musc
ram comunicante cu laringeu sup = ansa lui Galen
fibre senzitive dest laringe si port laringiene a faringelui
fibre somatomotoare pt m intrinseci

38
Q

fibre vegetative

A

fibre vegetative ,vasomotorii - postgg din gg cervicali sup si inf
fibre vegetative secretorii - parasimpatice provin din laringeu sup si inf
