Aripiko carotid tsinga: anatomical marongerwo uye physiology ari mudziyo

Carotid tsinga - chikuru vascular dzidzo iyo inopa mashoko arterial ropa racho uropi rayo goko, dehenya chiso, sezvimwe tsandanyama kuti ganda. Panyaya iyi, mubvunzo dzokuziva chaiyo nzvimbo mudziyo uyu haakonzeri matambudziko, sezvo kunyange epamba vanoziva kupi carotid tsinga. Kutaura zvazviri, mumwe anogona palpate yake pulsation ari carotid Triangle pamusoro anterolateral pechiso mutsipa.

Anatomical mamiriro carotid tsinga

In anatomical mazwi carotid tsinga ndiye mudziyo ropa, riri chikamu kutsemuka gwara. Panguva iyoyowo zvakananga kubva kutsemuka chematenga unotii chete akasiya nevakawanda carotid tsinga, asi yakafanana mudziyo rworudyi hafu muviri rinobva kubva brachiocephalic hunde. Section kurudyi subclavian uye zvakajairika carotid arteries, brachiocephalic hunde, bazi kubva zvakananga kubva kutsemuka chematenga, apedza, achipa kuenderera midziyo caliber duku.

Nzvimbo carotid tsinga, anonzi neurovascular tsapo, umo mamiriro ndiyewo ari vagus etsinga , pamwe mutsinga. Kumativi maviri nevakariri carotid tsinga akaendisa kwokunze uye munyika carotid arteries. Boka ravo uye Nomenclature vari azvaitwa nzvimbo ropa rive.

The womukati carotid tsinga kugutsa okisijeni kudiwa ari cranial zvomukati yaiva mukati maro. Saka panoparadzana mwoyo muruoko yayo mhango kuumba arterial network iri husingakwanisi dzichipfekeka nokuvhiringidzirwa midziyo uye mwoyo. Pakukora ari cavernous sinus, riri kumativi ari sella turcica, izvozvo anotuma Anterior chepfungwa bazi zvakabatana kuti tsinga chete zita pakatarisana parutivi munhu mberi unobva tsinga. Uyewo, dzomunyika carotid tsinga anopa nepakati uye posterior matavi chepfungwa, vanotumwa kuti uropi hwako. Saka phylogenetically akaronga kuti meninges, kuwedzera dzakapfavirira, anopa kwokunze carotid tsinga kusvikira padziva zvinosanganisira zvose chiso uye masticatory tsandanyama, ganda kumeso uye musoro, mazino, nasal mhango uye muchadenga.

Hemodynamics uye physiology of carotid arteries

The anatomical nemamiriro kutsemuka arch anokosha, sezvo ari elasticity rwengarava ropa. Kutora rimwe ropa lumen ayo carotid arteries itakurwe nawo musoro. Inenge 25% cardiac goho inowira uropi, iro rinotsanangura yakakwirira caliber yacho carotid arteries. Kamwe moyo inotevera mugove rutapudzo kudzinga ropa mukati yeropa, ivo kundoitora kota.

Munzvimbo weboka nevakariri carotid tsinga iri dzidzo maviri zvakananga iripo, iyo inonzi bhora hope. Iyi nzvimbo yevanhu pamutsipa, uko carotid tsinga riri rokumusoro pamucheto laryngeal thyroid shwashwa. It ane vakawanda receptors uye peripheral chiratidzo kubatana, kuratidza mabasa mwoyo. Kana cardiac goho riri duku, kuti Kanotokonya gadziriro iri kusangana zvishoma kumanikidzwa, uye nokudaro zvinoita vasomotor centre. Kana kumanikidzwa ari arterial mubhedha kumusoro, namahwindo dzinovaka. Pane uchapupu hwokuti kuti mapoka Kanotokonya izvi zvinogona riri rose mudziyo. Naizvozvo, nzvimbo carotid tsinga harifaniri kusvinwa kana kumanikidzirwa zvipfeko.

Saka lingual tsinga amutambanudzira kubva zvokunze carotid, yakatowanda dhayamita, asi rwunotumirwa mutauro. Izvi rinopa simba kweropa maitiro uye kuramba tembiricha, uyewo kuzivikanwa kuravidza. Paro dzeropa nomumugwagwa kwaitora nguva zvikuru pane ari mukuru carotid arteries, iyo inoita kubvisa kupinda mhango cleavable makabhohaidhiretsi muromo.
