Jirridda Brachiocephalic: ka fikirka iyo qeexidda

fikirka ah "jirridda brachiocephalic" la sii daayo in anatomy ee dadka iyo xayawaanka labadaba. Maanta aan ka hadalno this si faahfaahsan.

fikradda guud

Magaca jidhkan iska hadlaayo. jirridda Brachiocephalic ka quseyo ee khadka dhexe ee sternum ka guuro. Wuxuu ka dibna kor u soo fuulaa, obliquely, ka dibna dib u kor, iyo heerka of wadajir acromioclavicular u qaybsan yahay laba halbowlayaasha. Waxay ku taallaa hore ee hunguriga cad, taas oo carruurta waa la daboolay by qanjirka thymus, oo uu leeyahay dherer yar oo saddex ilaa afar sentimitir.

Dhallaanka, marar badan ayuu tsefaladu qaybsada on dhigoodu sternoklavikulyarnuyu ee saddexagalka hore ee qoorta.

jirridda qofka

In aadanaha, jidhkan leedahay qaab dhismeedka kor lagu sharaxay. Waxaa sida caadiga ah waa gaaban iyo qaro weyn weel, oo laamaha laba halbowlaha xaq in labada dhinac - midig oo hore - waxa daboola pleura ah. In bidix qayb ka mid ah jidhka ka mid ah nin ka mid ah halbowlaha halkaas. Haddii kale, markabka lagu magacaabo jirridda brachycephalic (ka magac Laatiin ah) ama halbowlaha innominate.

Ninka la brachiocephalic foosto ee ku xiran cuduro gaar ah. ka mid ah kuwa soo socda:

• Atherosclerosis (raasamaal oo kolestarool ah iyo xaydha ku saabsan gudaha halbowleyaasha);
• cilladaha lagu dhasho,
• hemangioma (buro-caanood in uu yeesho ka xididdada dhiigga yar);
• dhaawac halbowlaha;
• aneurysms (Lumen ballaarinta waa laba jeer ama in ka badan);
• laamaha xafiiltamaan nabar occlusive (jebinta permeability vascular, taas oo horseedaysa ischemia maskaxda iyo jirka (sare)).

Haddii aad qabto dhibaatooyin la markabka habboon in loo gudbiyo qaliin vascular.

jirridda of xayawaanka

iyaga habdhiska jirridda brachiocephalic soo socda. Waxaa ka duwan aadanaha ah oo la faray in ay soo galo galay saabka xabadka, oo halkaas hore u qaybsan yahay laba halbowlayaasha bidix (xaq aadanaha). Tani waxay dhacdaa at heerka of araxda labaad thoracic.

In xoolaha qaar ka mid ah, sida eyda iyo doofaarrada, jirridda brachiocephalic halkaas, halkii ay isaga - laba halbowlayaasha tagay in ka soo baxay xafiiltamaan ee aortic. Laga soo bilaabo mid ka mid ah xididdada, loo yaqaan brachiocephalic ah, tegi halbowlayaasha artery, oo dhiig madaxa xoolaha qaado. marka laga reebo waa faras in uu leeyahay a xididdada yar yar waxa ay ka tagaan.

jirridda Brachiocephalic bixisaa dhiig madaxa, luqunta, addinka xabadka derbiga xabadka.

Xaaladaha qaarkood, stem si hoose ee qanjirka thyroid waa halbowlaha thyroid liita. Sababo la jirridda la magdhow karo by la'aanta ama maqnaanshaha of mid ka mid ah weelashii thyroid ka.

laamaha jirridda

Si loo guto, oo weelasha oo ka halbowlayaasha subclavian leeyihiin noocyada kala duwan gaar ah. From halbowlaha ay tagaan laamaha soo socda:

• jirridda feeraha-afka ilmo-galeenka siisa dhiig in muruqyada qoorta iyo engegaa. wada tago la halbowlayaasha sida vertebral afka ilmo-galeenka oo qoto dheer iyo (in ariga oo doofaarro ah) ama hore (carnivores) ee. In fardo, jirridda waa laan madax bannaan.
• halbowlaha afka ilmo-galeenka Deep siisa ah "extensors" madaxa iyo qoorta. Diverges in muruqyada qoorta, iyada jihada cranial. On qoorta, iyo sidoo kale noocyo laan spinal rahaamad labaad. The doofaarka iyo eyga, halbowlaha tani waa laan ka mid ah jirridda feeraha-afka ilmo-galeenka ah.
• halbowlaha Vertebral waa uumi. Sidoo kale cranially faray. Gaaritaanka khariiradda ah, soo bandhigtay laanta muruqyada iyo xangulada maraa godka ku araxda afka ilmo-galeenka ah (khariiradda) hore iyo qoorta noocyada xoolaha Jidka socodka weyn (yeedhay damaanadda). In lo wada guuro la laamaha kor ku xusan. carnivores A yahay weel dhiiggii ugu horeeyay, taas oo ka halbowlaha subclavian ka tago.
• Plechesheynaya halbowlaha (sidoo kale loo yaqaano halbowlaha afka ilmo-galeenka kore) ogolaanaya muruqyada qoorta dhiig, dewlap iyo meesha laga galo in sanduuqii. doofaarka ee ka fog iyada jirridda thyroid guuro.
• The halbowlaha thoracic gudaha iyo kuwa dibadda. Caagga saamiga gudihiisa la faray caudal in ay sternum ka, ay timaado feeraha toddobaad iyo mudacyadii. weel Her final la soo bandhigay halbowlaha musculo-muruqa neefsiga. soodagi dheeraad ah iyo qalabka dhiigga caloosha ku saabka muruqyada, doofaarrada iyo carnivores sidoo kale qanjirka caanaha. halbowlaha dibada marayaa feedhii hore iyo laamaha qoto dheer ee murqaha naaska. halbowlaha Tani waa halkii ay si liidata horumariyo.

Next xoolaha jirridda brachiocephalic, halbowleyaasha Left socda uu noqdo halbowlaha axillary ah. Iyagu waa isha ugu muhiimsan ee sahayda dhiiggii addimada thoracic ah.
