Bifurcation - ndi ... ndi kung'ambika bifurcation

Mawu akuti "bifurcation" ntchito mabuku mankhwala kwa nthawi yaitali. Lero tikudziwa mfundo zingapo monga mu kapangidwe kake mawu.

Tanthauzo la mawu akuti

Bifurcation - ndi kugawanika iliyonse. Komanso, ambiri mfundo zimenezi zimasonyeza kuti gulu anachitika m'madera 2 ndi pafupifupi awiri chomwecho. Nkofunika kuti nthambi ziwiri diverging pansi kumathandiza kupeza ngodya zabwino mofanana. zitsanzo zabwino atumikire monga bifurcation wa carotid mtsempha wamagazi, msempha kapena trachea.

Ngakhale kuti mawu bwino kuti "kukwatulidwa" ndi mankhwala, n'zotheka ntchito m'madera ena. Mwachitsanzo, mu madera zina pali chinthu monga mtsinje bifurcation.

Mtengo wa bifurcation mankhwala

Kupatukana m'zotengera awiri pafupifupi wofanana nthambi kapena trachea ndi phindu lalikulu. Mwachitsanzo, bifurcation kwa msempha amalola zambiri kupereka magazi m'makona onse m'munsi. Akugwirizana chotengera yaikulu ya thupi lamanja ndi kumanzere mitsempha femoral. Pa nthawi yomweyo akulola tracheal bifurcation mpweya okwanira awiri kuwala mofanana. Kotero kuti bifurcation - ndi chodabwitsa zofunika mankhwala.

pa msempha

Bifurcation - ndi gulu pawiri pafupifupi wofanana. Pankhani ya msempha, mawu akuti lakhala likugwiritsidwa ntchito kwa nthawi yaitali, koma kwenikweni si zoona ndithu. chakuti wamba mitsempha iliac si zofanana ndi mbali ya ntchito yophunzitsa msempha ndi nthambi zake zokha. Tamarayo akupita pansi ngakhale m'munsi mwa mawonekedwe a ang'ono chotengera woonda.

Kung'ambika bifurcation limapezeka pa mlingo wa lumbar linkawonongeka IV. malo ndi mmodzi wa yovuta kwambiri mawu a mtendere chotengera ku sanasiye kutiuza magazi. Chakuti apa ndithu zambiri kung'ambika kung'ambika. Chifukwa lotereli kuti bifurcation - malo omwe nthawi zonse poyera kuti chikoka kuchuluka kwa magazi. Ndi apa kuti ayenera anagawira awiri mitsempha wamba iliac. Chifukwa ndi wosiyana kugwedezekagwedezeka magazi ndi mavuto aakulu utuluke izi pa khoma chotengera pa malo bifurcation a.

Kuwonjezera zotheka aneurysm wa msempha mu kugawana pali preconditions kwambiri mapangidwe mipukutuyi atherosclerotic. Ichi ndi chifukwa chakuti ululu wa chotengera komwe kuli mtsempha wamagazi bifurcation m'magulu 2, izo zimachitika nthawi zambili kuposa zinthu zina. Pang'onopang'ono kukula kukula, zolengeza uyu angathe kuchepetsa magazi kwa ziwalo m'chiuno ndipo m'munsi malekezero.

kung'ambika bifurcation zotupa syndrome

matenda Ichi ndi choopsa kwambiri. Umabweretsa kwambiri cha ululu kwa wodwalayo ndipo akhoza kwambiri kuvulaza thanzi lake. matendawa nthawi zambiri limodzi ndi kugonjetsedwa osati m'dera la bifurcation kung'ambika wokha, komanso m'madera ena. Tikuyankhula zokhudza aimpso ndi wamba mitsempha iliac. Komanso pathological ndondomeko chimafikira yekha kotala odwala.

Mbali yaikulu ya syndrome kung'ambika bifurcation ndi matenda a magazi aziyenda bwino mu zotengera za m'makona m'munsi ndi mafupa a chiuno. Choncho, akuluakulu matenda mawonetseredwe awa zikugwirizananso kuti madambwe. Ngati ife kulankhula za m'makona m'munsi, odwala kumva ululu zokwanira. Ali otchedwa likukulira claudication.

mawonetseredwe izi matenda ndi chimaonetsera, chifukwa kuti ischemic (kupanda kotunga mwazi) ululu ali ovuta kwambiri. Chinthu chapadera cha claudication likukulira ali syndrome wa bifurcation kung'ambika n'chakuti ululu si isanafalikire mu tibia, ndipo makamaka m'chiuno ndipo ngakhale minofu gluteal.

Ponena za mawonetseredwe ya ziwalo m'chiuno, ndikofunika kuzindikira kuti iwo ndi wapadera kwa anthu. Iwo anafotokoza mu kuchepa libido ndi ofooka erection ku mpheto. Matendawa syndrome kung'ambika bifurcation chotupa zochokera kuchepa magazi ziwiya malekezero m'munsi anatsimikiza ndi kuyeza BP mu luso ndi mphamvu ya zimachitika yoweyula. Kutsimikiza matenda anatenga sfigmo- kapena rheovasography. Popanda chithandizo chapadera choopsa mwa nthendayo kuwonjezera otaya lapansi.

Kudulidwa kwa mtsempha wamagazi ndi carotid

Bifurcation - chodabwitsa khalidwe osati kwa msempha, komanso kuti mtsempha wamagazi ndi carotid. Chigawo ake limapezeka pa mlingo wa m'mphepete m'munsi mwa chithokomiro chichereŵechereŵe. Pankhaniyi, lamanja ndi kumanzere carotid mitsempha, ngakhale kuti zimasiyana kwambiri Utali awo malo, kuti lagawidwa nthambi kunja ndi mkati muno.

Monga momwe zilili ndi msempha, chotero bifurcation - malo a kuchuluka ngozi. Komanso akhoza kukhala aneurysms ndi njira zina pathological chifukwa kuchuluka kukhudzana ndi magazi pa malo a chotengeracho. mtsempha wamagazi Flue n'chochepa awiri ake pafupifupi nthawi 2 poyerekeza ndi "kholo la" wake. Chifukwa, izo ziri mu malo bifurcations kuti kochulukira trombotizatsii chiopsezo ndi embolization. Pachifukwa ichi, zinachitikira kwa mawu lolingana madokotala matenda makamaka anafufuza mitsempha magawano danga, kenako mbali otsala zace.

Bifurcation yaikulu njira pneumatic

The trachea thupi dzenje lomwe ndi udindo kuchititsa mpweya bronchi, ndiyeno m'mapapo. Mu dongosolo lake lili ambiri (mpaka 26) mphete cartilaginous kuti kuteteza trachea umatsika.

tracheal bifurcation limapezeka pa nsonga chapamwamba cha V thoracic linkawonongeka. Ana, ndi pang'ono apamwamba. Komanso inspiratory bifurcation mlingo ankatembenukira ndi za 2-3 masentimita downwards. Apa thirakiti aakulu aeriferous lagawidwa lamanja ndi lamanzere bronchi chachikulu. M'tsogolo, iwo aphwanya mobwerezabwereza. The tanthauzo lenileni la tracheal bifurcation akuwaza lina lalikulu njira pneumatic mu 2 ang'onoang'ono. M'pofunika kutenga katundu wa mpweya mwachindunji mapapo onse. The bifurcation wa trachea ndi amachitidwa pa makona pafupifupi 70 ^Inu. Inhalation yogwira chigawo mwina penapake kuonjezera.
