Cuneiform ithambo Yekhanda. Incazelo.

Ithambo nhlonhlo emise etholakala maphakathi base Yekhanda. indima yayo ukudala iqoqo ohlangothini izindonga Yekhanda, izimbobo kanye izimbotshana (ubuchopho kanye ebusweni). ithambo cuneiform wuhlobo ifomu eziyinkimbinkimbi. Lokhu ithambo sakhiwa umzimba ngamabhangqa amathathu ezihlobene, amaphiko (ezinkulu nezincane), ezihlobene iphiko emise.

ithambo Cuneiform Yekhanda - Incazelo

NgoLwesine kutholakale isidumbu sendoda ithambo sphenoid ufana ukuma obuhlukahlukene umzimba weJiyomethri - cube. Ngaphakathi kuba itheku sphenoid (ingaphakathi). Ngaphezu kwalokho, ithambo occipital has evele amaningi, zonke kubo - Six: ubuchopho, emuva (e abadala kuba adherent ukuba ingxenye core wethambo, ngaphambili (sidlule ngokushelela ku ebusweni ephansi), zombili.

Isici esiphawulekayo ubuchopho (engenhla) kobuso ekhosombeni iphawulwe ngokuthi "sehhashi Turkish". Maphakathi nalo iyona fossa pituitary. Kuyinto indlala pituitary. Ngaphambili ikhefu kuyinto Lobe sehhashi kokuba ilungiselelo lateral. Isihlalo emuva impela high. Le ngxenye lateral we backrest ukwakha enalokho kuthambekela ezingemuva ezihlobene. Ezansi ngemuva "sehhashi Turkish" nhlangothi zombili inkatho yezinto. Ibizwa nangokuthi "balele", ngoba itholakala Umthambo carotid. Ohlangothini olungaphandle, eduze emuva carotid imisele has a ithebhu nhlonhlo. Lokhu kwenza ushintsho ulimi inkatho inkatho okujulile. Inkatho, ngokuhlanganyela ichopho mbhoshongo ethempelini ithambo, a somnolence stop imbobo. Ngemva Sleepy imbobo kwangaphakathi ku ingaphakathi cranial ka somnolence isiteshi akube kusakhulunywa carotid kwangaphakathi Umthambo.

ithambo Sphenoid, okungukuthi, ngaphambili ingxenye ubuso bayo, ine ijamo side futhi sifana ikamu. Funisisa ngesimo a keel abukhali kuziwa kwamanzi phansi yokuxhuma ithambo ipuleti ethmoid. Ohlangothini yokhalo ngamunye ahlelwe ithambo zezinhlangothi ukuma okungajwayelekile. Ibeka imingcele ezindleleni ukuvuleka okuhloswe e womoya ingaphakathi nhlonhlo emise. indiza Lateral wethambo sphenoid ukuba phambili phansi pass in amaphiko ezincane nezinkulu.

iphiko Small - ipuleti umusi esukela sphenoid ithambo umzimba ngezinqubo ezimbili, phakathi lapho isiteshi ezibukwayo. Emaphethelweni phambi amaphiko kukhona uhlobo encane igawula. Lezi emaphethelweni axhunyiwe engxenyeni esemkhathini ka ithambo engaphelele futhi ipuleti wethambo ethmoid. Unqenqema ezingemuva amaphiko amahhala amancane, ezindaweni zawo abushelelezi. On ngamunye medial ohlangothini amaphiko elise inqubo anterior. Ukuze phambili posterior inqubo ziyakhula igobolondo kanzima zobuchopho.

iphiko elikhulu ibhangqwe. Luqala ngokunikela isisekelo ezibanzi ohlangothini ebusweni umzimba nhlonhlo emise. Ngamunye amaphiko ngasesinqeni has ukuvuleka ezintathu. Ngomuntu oyedwa beso, esemgwaqweni ngaphezu kwamanye, kudlule legatsha emsipheni trigeminal. Maphakathi iphiko has a imbobo for ukudlula enye ka emsipheni trigeminal. Ngokusebenzisa ukuvuleka langemuva iphiko engela zone lingena Umthambo skull meningeal. iphiko elikhulu ine evele ezilandelayo: yesikhashana, maxillary, esemkhathini kanye nobuchopho.

Scion iphiko (yena futhi kabili) elisukela umzimba ithambo endaweni ekuqaleni iphiko elikhulu phansi thwi. Zimbili zezinhlangothi inqubo pterygoid: medial kanye lateral. ipuleti Medial iqondiswe ekufezeni ingaphakathi acinene, kanye lateral - maqondana fossa infratemporal. ipuleti Front spliced ndawonye. Ahambisana Naleli ipuleti washintsha ukwakha iphiko imbobo. I plate amabili abahlukene ezansi ucwecwe-cut. ipuleti Medial kuyinto esidenyana futhi iyincane ngaphandle lateral.

ithambo Sphenoid iqala yokuzigxilisa ubheke leli sonto lesishiyagalolunye wokukhula kwengane esiswini.
