Uphi Umthambo carotid: isakhiwo yokwakheka futhi izitho zomzimba bomkhumbi

Carotid Umthambo - imfundo ezinkulu semithambo enikeza igazi lwemithambo of nezicubu ubuchopho kanye egobolondweni, skull ubuso, ukulingisa imisipha esikhunjeni. Kulokhu, umbuzo ekutholeni indawo esiqondile lesi isitsha akakubangeli izinkinga, njengoba ngisho emizi ukwazi lapho Umthambo carotid. Empeleni, umuntu angabona palpate okusizwa ukushaya yakhe unxantathu carotid phezu anterolateral entanyeni.

isakhiwo yokwakheka carotid Umthambo

Ngamagama yokwakheka Umthambo carotid iyona isitsha igazi, oyingxenye yomzila yomthambo i-aorta. Ngesikhathi esifanayo ngokuqondile yomthambo i-aorta lwaleli uhamba kuphela kwesokunxele ezivamile carotid Umthambo, kuyilapho esibuthakathaka ezifanayo isigamu kwesokudla umzimba kuvela esiqwini brachiocephalic. Isigaba phezu subclavian kwesokudla futhi ezivamile carotid lemithambo isiqu brachiocephalic, azikhandle ngokuqondile lwaleli yomthambo i-aorta, luphela, enika izitsha ukuqhubeka osezingeni ezincane.

Indawo lapho umfula carotid, ngokuthi lenqwaba neurovascular, lapho isakhiwo futhi emsipheni vagus , kanye emithanjeni. Kuzo zombili izinhlangothi okuvame carotid Umthambo bamuke zangaphakathi nezangaphandle carotid imithambo. division yabo futhi ngesilwane esifuywayo kukhona ngokulandelana endaweni liningi igazi.

I yangaphakathi carotid Umthambo ukwanelisa nesidingo-mpilo kwezitho cranial elise ngaphakathi kwalo. Ngakho-ke ingena phakathi komgodi yayo ukuze kwakhiwe inethiwekhi lwemithambo olumelana ukuphazamiseka obusebenzayo izitsha inhliziyo. I ukushuba we itheku cavernous, sise izinhlangothi turcica sella, ithumela anterior legatsha cerebral ixhunywe Umthambo kwegama efanayo uhlangothi ngumuntu phambi yokuxhuma Umthambo. Futhi, yangaphakathi carotid Umthambo unika amagatsha maphakathi kanye posterior palsy, okuyinto ithunyelwa ubuchopho bakho. Ngakho phylogenetically sihlelwe ngendlela yokuthi meninges, ngaphezu elithambile, uyabanikeza zangaphandle carotid Umthambo echibini okuhlanganisa zonke izicubu ezithile ebusweni futhi masticatory, isikhumba ebusweni futhi ikhanda, amazinyo, ingaphakathi acinene bese umzila.

Hemodynamics futhi izitho zomzimba kwemithambo yegazi carotid

Isakhiwo yokwakheka yomthambo i-aorta Arch ekhethekile, njengoba kuyintando kuyaqina imithambo yegazi. Ukuthatha ezinye igazi inesikhala yayo, imithambo carotid bawuthwale ekhanda. Cishe 25% okukhipha inhliziyo ewela izicubu ubuchopho, echaza ubukhulu eliphezulu imithambo carotid. Uma inhliziyo ingxenye elandelayo nokwehla saxosha igazi ku le-aorta, ziyaluthola ingxenye yesine.

Esikhundleni division of the ezivamile carotid Umthambo emfundweni amabili akhethekile atholakalayo, okuthiwa ibhola bayozela. Le ndawo entanyeni womuntu, lapho umfula carotid itholakala emaphethelweni engenhla laryngeal yegilo uqwanga. It has a inombolo enkulu receptor kanye neuropathy isignali isixhumanisi, khomba ukusebenza inhliziyo. Uma okukhipha inhliziyo incane, uhlelo yokwamukela kubhekene ingcindezi kancane, futhi ngaleyo ndlela kuvusa isikhungo vasomotor. Uma ingcindezi embhedeni lwemithambo kuphezulu, ngempendulo avaliwe. Kukhona nobufakazi ukuba lezo amaqembu yokwamukela asezindaweni ezikahle kulo lonke isitsha. Ngakho-ke, indawo lapho umfula carotid akufanele apitshikile noma ophoqelelwe izingubo.

Ngakho Umthambo lingual, esukela carotid zangaphandle, ubukhulu nakakhulu, kodwa ithunyelwa ulimi. Lokhu kukunika ke uhlelo strong kwegazi nokugcina izinga lokushisa, kanye nokwamukelwa ukunambitheka. Iphinde egazini kancane kakhulu ayinhloko carotid imithambo, okuyinto eyenza ukuncela ku ingaphakathi cleavable carbohydrate umlomo.
