Q

traberculae carneae

A

tanki mišični snopi, ki so v celoti ali samo s konci pripeti na zid srca:

  • crista supraventricularis -> ločuje ostium atrioventriculare dextrum in ostium trunci pulmonalis
  • trabercula septomarginalis -> gre od septalnega zidu desnega ventrikla do baze m. papilaris

so stožaste oblike in pripeti na zidove ventrikla, v desnem so m. papillares anterior, m papilaris posterior in m. papillaris septales

18
Q

atrum sinistrum - sprednja stran

A

pokriva jo koren aorte

19
Q

atrum sinistrum - zadnja stran

A

se dotika požiralnika

20
Q

atrum sinistrum - zgornja stran

A

leva pljučna arterija

21
Q

atrum sinistrum - spredaj in spodaj

A

se nahaja levi ventrikel

22
Q

atrum sinistrum - zgornji zid

A

leva pljučna arterija

23
Q

atrum sinistrum - zadnji zid

A

bočno se nahajajo ostia venarum pulmonalium (dve levi in dve desni)

24
Q

atrum sinistrum - notranji zid

A

septum interatriale, tu je izboklina fossa ovalis

25
Q

atrum sinistrum - zunanji zid

A

naguban in pokrit v m. pectinati, tukaj je odprtina auricula sinistra

26
Q

atrum sinistrum - sprednji in spodnji zid

A

ostium atrioventriculare sinistrum in dvolistna zaklopka - cuspis anterior in cuspis posterior

27
Q

ventriculus sinister - sprednji zid

A

fascies pulmonalis in del fascies sternocostalis ob sulcus interventricularis anterior

28
Q

ventriculus sinister - sponji zid

A

fascies diaphragmatica

29
Q

ventriculus sinister - notranji zid

A

septum interventriculare

30
Q

ventriculus sinister - baza

A

nahajata se dve odprtini, ki ležita skoraj v isti ravnini:

  • ostium atrioventriculare sinistrum
  • ostium aorte in valva aorte in treh polmesečnih lističev
31
Q

septum cordis

A

popolnoma loči desne od levih delov, zgrajen je iz:

  • septum interatriale
  • septum interventriculare
32
Q

crux cordis

A

za diafragmalni strani srca se znotraj križajo septum interatriale, septum interventriculare in sulcus coronarius
zunaj se križajo sulcus coronarius in sulcus interventricularis posterior

33
Q

anuli fibrosi

A

tvorijo fibrozni skelet srca, med seboj tvorijo dva trigona fibrosa:

  • desni prstan atioventrikularnih odprtin
  • levi prstan atrioventrikularnih odprtin
  • prstan aortne odprtine
  • prstan truncus pulmonalis
34
Q

trigonum fibrosum dextrum

A

tvorijo ga levi in desni atrioventrikularni prstan ter aortni prstan

35
Q

trigonum fibrosum sinistrum

A

tvorita ga levi rob aortnega prstana ter sprednji rob levega atrioventrikularnefa prstana, ki se dotikata

36
Q

vertix cordis

A

na fibroznih prstanih se pripenjajo vlakna srčnih mišic, ki gradijo stene atrijev in ventriklov
v ventriklih se ovijajo v obliki osmice in tvori srčno zvezdo

37
Q

systema conducens cordis

A

prevodni sistem srca, ki ga tvorijo:

  • nodus sinuatrialis
  • nodus atrioventricularis
  • fasciculus atrioventricularis
38
Q

nodus sinuatrialis

A

nahaja se pod perikardom v sulcus terminalis desnega atrija, v neposredni bližini v. cava superior

39
Q

nodus atrioventricularis

A

nahaja se pred enokardom notranjega zidu desnega atrija v trikotnem prostoru imenovanem Kochov trikotnik (septm, ostium v. cave inferior, ostium sinus coronarius)

40
Q

fasciculus atrioventricularis

A

sestavlje iz truncusa, ki gre iz AV vozlov, prebija trigonum fibrosum dextrum ter se deli na desno in levo vejo: crus dextrum et crus sinistrum
