Skull womuntu

skull Human iyona skeleton zekhanda lakhe. Yabelana ngale skeleton ngezihluthu nobuchopho izingxenye.

Esikhathini ingxenye yobuchopho ngesimo lwamathambo ekhanda eduze ibhola. Isakhiwo le ngxenye siqukethe ezimbili parietal, frontal, occipital, yesikhashana, nezinye ezimbili amathambo Yekhanda yomuntu. Ngu uhlobo zonke izakhi kukhona ngokwanele aminyene amapuleti lwalugobile. Abizwa ithambo flat. umsebenzi wabo ukuqinisekisa ukuvikelwa zobuchopho ekulimaleni.

izakhi ngabanye of the amathambo asemzimbeni ikhanda zihlangene ngu ezivuzayo. Leli lunga libizwa umile. kumiswa weld Kwenziwa imiphetho jagged izakhi emibili elandelanayo. Kulokhu, usike omunye wabo ihlanganisa nezinye amazinyo.

skull womuntu ebuchosheni ingxenye has a ebusweni kuqhathaniswa bushelelezi (side futhi phezulu). Kumila ubuchopho embozwe mfihlo projection ahlukahlukene. Lokhu kungenxa yokuthi ugebhezi womuntu kule ndawo ehlangene le micu kwemisipha. Kumila Ubuye ukuvuleka. Ngokusebenzisa ukuwakhohlwa impumuzo futhi imithambo yegazi. Cishe ingxenye maphakathi skeleton ikhanda kukhona intuba enkulu (occipital), lapho uxhumano iyona asebuchosheni nomgogodla.

Emngceleni ka evele ohlangothini kanye isizinda Yekhanda elise orifice sokuzwa (yangaphandle). Ebusweni phansi occipital ithambo ilungu has izinqubo articular okuyinto amanga nhlangothi zombili Magnum foramen. Ngalezi izinqubo skull womuntu ixhunywe umgogodla.

Ngaphambili indawo skeleton ikhanda kuhlanganisa pair of isakhiwo bony izici. Lezi zinto zihlanganisa maxillary, acinene, zygomatic, LasePalatine, nezinye amathambo. Mandibular ithambo isici ayibhangqene.

Esikhathini phambi endaweni lwamathambo ekhanda ahlelwe umlomo, ikhala kanye neso enethiwekhi.

Elingenalutho presents ngaba nokucindezeleka okukhulu. Kuyo amanga yeso futhi amandla ayo, kwakheka imithambo yegazi nezinzwa.

I ingaphakathi acinene ivula kuvulwa phambi e kobuso skeleton ikhanda. Ahambisana Naleli ingaphakathi acinene ixhunywe pharynx esebenzisa izimbobo ezimbili. Isigamu kwesokudla futhi kwesokunxele ingaphakathi akhiwa ngodonga sokuhlukanisa ithambo. Ngesigamu amavesi acinene ngamunye akhiwa amathambo amathathu.

I ngalo ingaphakathi ngomlomo ahlukaniswa ekhaleni ngosizo izakhi LasePalatine amathambo izinqubo wethambo maxillary. Emaphethelweni engezansi bese engenhla emihlathini ukhawule umlomo singatsheki.

Ugebhezi womuntu izingxenye efanayo futhi izakhi skeleton ezincelisayo ikhanda. Nokho, isici ebalulekile skeleton ikhanda zabantu kuyingxenye kakhulu evuthiwe zobuchopho. Ngo ezincelisayo, ingxenye esithuthuke kabanzana bengaphambili.

Izakhi ezakha skull womuntu kuzalwa esimweni Ukuqina sekuyenzeka akuphelele. Basuke eyakhiwa sezicubu zezinzwa futhi uqwanga. Occipital, ithambo engaphelele kanye nezinye izinto eziningi ziqukethe izingxenye eziningana. Ngesikhathi emaphethelweni izakhi skeleton of the kuzalwa amabombo kungekho amazinyo. Ngakho, uxhumano senziwa esebenzisa imidweshu ulwelwesi zezinzwa futhi akukho ezivuzayo. Ezindaweni lapho engeli uzwane ezakhi eziningana ithambo, yenza okufanayo nakuyo ulwelwesi ukwakha fontanels.

With ukuthuthukiswa ingane kwenzeka ukuhambisana amanye amathambo nomunye, ukwakheka sutures, fontanelles yene. Ngakho, kancane kancane igcwaliswe inqubo Ukuqina sekuyenzeka, ithambo ukukhula iqala.

Uhlaka lwamathambo ekhanda, kanye, futhi wonke umzimba, kulo lonke yokuphila komuntu siyashintsha. Ngakho, nge engamashumi amathathu, njengoba umthetho, inqubo amalunga overgrowing iqala. Lapho ufika umuntu ubudala, namazinyo aqala ukuwela futhi sithela iseli ababehlezi kuyo.
