Ngoonobumba lithambo Amaza. Inkcazelo.

Ithambo nesinqumka emile ibekwe esizikithini kwisiseko ukakayi. indima yayo kukudala iseti kweendonga icala yokakayi, imingxuma kunye nemingxuma (ingqondo kunye nobuso). ithambo Uhlobo lonobumba ifom entsonkothileyo. Le lithambo sakhiwa umzimba kunye ngababini ezintathu waso, namaphiko (ezinkulu nezincinane), waso iphiko-ezimile.

lithambo ngoonobumba intamo - Description

Umzimba ithambo sphenoid ifana imilo mgaqweni umzimba zejometri - i ityhubhu. Ngaphakathi lelona sinus sphenoid (kwisisu). Ukongeza, le ithambo Occipital iye iindawo ezininzi, bonke - emithandathu: ubuchopho, emva (abadala ukuba unamathele ukuba yinxalenye engundoqo wethambo, ngaphambili (igqitha kakuhle kwi kwamanzi aphantsi), kwicala ezimbini.

A isici esasenza yobuchopho (phezulu) ubuso elitywinwe iphawulwe njengo "undim Turkish". Kwiziko sawo fossa yebhinqa. Yeyona ingqondo yebhinqa. Le ngontsi akuyona lobe iinqwelo ukuba ilungiselelo lateral. Back seat kakhulu eliphezulu. Inxalenye zisecaleni backrest ukwenza waso ngasemva bethana. Emazantsi ngasemva "iinqwelo Turkish" kumacala omabini emseleni esisemgceni. Libizwa ngokuba "yokulala", kuba ibekwe umthambo carotid. Kwicala elingaphandle, kufuphi Nemiqela carotid umva uye tab imnyama. Oku kukhuthaza iinguqu ulwimi groove emseleni enzulu. Emseleni, libambisene ngencam iphiramidi etempileni ithambo, a somnolence stop umngxuma. Emva umngxuma ngaphakathi sleepy em- cranial of somnolence channel lukhupha ngaphakathi carotid umthambo.

ithambo Sphenoid, oko kukuthi, inxalenye phambi kobuso bayo, ine i side kwaye ufana ikama. Kama kwi ngokohlobo zikhangeleke elibukhali uza kumphezulu ezantsi yokungena kwi ithambo nembasa ethmoid. Kwicala ngalinye kummango zilungiswe amacwecwe thambo shape engagunyaziswanga. Ibeka Ekungeneni ejoliswe kwi womoya kwisisu nesinqumka-ezimile. moya zisecaleni ithambo sphenoid ukuya ngaphambili ukuya emazantsi yokupasa kwamaphiko ezincinane nezinkulu.

iphiko Small - ipleyiti ngomphunga osusela emzimbeni ithambo sphenoid ziinkqubo ezimbini, phakathi apho isitishi olubonakalayo. Iikona phambi amaphiko uhlobo amancinci NOKUCUKUCEZA. Ezi Iikona uqhagamshele kwinxalenye Orbital ye ithambo ngokungqalileyo yaye ipleyiti wethambo ethmoid. Edge emva kwamaphiko zifumaneka simahla amancinci, umphezulu yabo egudileyo. Kwi nganye amaphiko kwicala medial ibekwe inkqubo sobuKristu. Kwinkqubo ngaphambili kunye ngomva ngokwemizuzu iqokobhe nzima zobuchopho.

iphiko Large nesithandwa. Kuthathela isiseko esibanzi umphezulu icala lomzimba nesinqumka-ezimile. Ngalinye amaphiko aligalele esisekweni somongi ezintathu. Esebenzisa imbobo omnye, nto leyo ibekwe ngaphezu enye, uwele isebe le-luvo trigeminal. Embindini iphiko inomngxuma ngenxa sicatshulwa omnye ka-luvo trigeminal. Ngokusebenzisa amathuba kwindawo etikweni engile ngasemva ingena kwemithambo ukhakhayi meningeal. iphiko enkulu imiphezulu zilandelayo: zezomzuzwana, maxillary, Orbital nobuchopho.

Nakumlibo iphiko (he Kwakhona kabini) inabela nomzimba ithambo kwisiza ekuqaleni iphiko enkulu ezantsi nkqo. Kukho amacwecwe amabini inkqubo pterygoid: medial and lateral. ipleyiti Medial ijoliswe kwabo lweHo- ngeempumlo, kwaye lateral - eya fossa infratemporal. ipleyiti Front spliced kunye. Ngaphaya plate diverge ukwenza iphiko kunye emngxunyeni. Iipleyiti ezimbini bahlukane kwi emazantsi ngefoyile ye-aqingqiweyo. ipleyiti Medial kancinci ixesha elide kwaye sincinane, ngaphezu lateral.

ithambo Sphenoid uqala ziyahlala kwi kwiveki wethoba Palsy.
