Skull kwabantu

skull ngoluNtu amathambo entloko. Yabelana le skeleton ngaphambili nobuchopho iindawo.

Kule ndawo yengqondo ngohlobo amathambo entloko kufutshane ibhola. Ubume kule nxalenye iquka Parietal ezimbini, ngokungqalileyo, Occipital, zezomzuzwana, kunye nezinye ezimbini namathambo ukakayi womntu. Xa uhlobo lweziqalelo bonke ngokwaneleyo iipleyiti zamafu egobile. Ezi zibizwa ngokuba ithambo flat. umsebenzi wabo ukuqinisekisa ukhuseleko ingqondo umonakalo.

izinto ngabanye wethambo kuphahla ezi zentloko yenu zibaliwe uncediswa beentanda. Leli lunga kuthiwa zokubhala. ukubunjwa weld into elintlangothi ezitsolo inezigaba ezibekwe ngecala wenziwe. Kulo mzekelo, wonqanyulwa, omnye wabo kuquka ezinye amazinyo.

skull yabantu isabelo kobuchopho kumphezulu okuhambe (ecaleni kunye ngaphezulu). Isiseko yobuchopho wayifulela lezitenxo kunye noqikelelo ezahlukeneyo. Oku kubangelwa yinto yokuba ukakayi kwabantu kule ndawo edibene imicu kwezihlunu. Isiseko kwakhona somongi. Ngokusebenzisa zona imizwa kunye imithambo yegazi. Malunga nama kwinxalenye embindini amathambo entloko na indawo enkulu (Occipital), apho ukuxhumeka ingqondo kunye umnqonqo.

Xa umda imiphezulu kwicala kunye Amaza indawo orifice eziviwayo (elingaphandle). Umphezulu ezantsi ilungu ithambo Occipital iye iinkqubo articular apho emise macala omabini magnum foramen. Ngezi nkqubo ukhakhayi lomntu liqhagamshelene kuntlahlahlungulu.

Le ndawo ngaphambili amathambo entloko ubandakanya ngeembadada nangamathambo izinto. Ezi ziquka maxillary, ukuthetha kwam ngeempumlo, zygomatic, iPalatine, kunye nezinye amathambo. element bone Mandibular yena uhamba.

Kule ndawo phambi amathambo entloko zilungiswe neziseko iliso umlomo, impumlo, kunye.

Ulenze lizisa a ukudandatheka. Kuyo kukho lweliso lakho kunye nezihlunu zayo, imithambo yegazi kunye luvo.

Komgodi ngeempumlo ivula ekuwuvuleni ngaphambili kwi kumphezulu amathambo entloko. Ngaphaya kwisisu ngeempumlo liqhagamshelene pharynx esebenzisa imingxuma emibini. Isiqingatha ekunene ekhohlo lweHo- akhiwa izahlulelo ke ukulaba ithambo. Kwisiqingatha ngasinye kwezi zicatshulwa ngeempumlo akhiwa amathambo ezintathu.

Komgodi ngomlomo siyahlukana empumlweni ngoncedo eziqalelo bone iPalatine kunye neenkqubo ze-ithambo maxillary. Kungqameko ezisezantsi nemihlathi aphezulu imiqathango umlomo yokuxazulula.

Le skull wabantu iindawo ezifanayo neziqalelo amathambo ezanyisayo entloko. Noko ke, kukho inkalo ebalulekileyo intloko amathambo abantu yinxalenye kakhulu aphuhliswe kakuhle ebuchotsheni. Xa ezanyisayo, inxalenye eziphuhlileyo ngakumbi ngaphambili.

Iziqalelo ezakha ukakayi yabantu elisandul kwimo kwamathambo ayiphelelanga. Ziye ke yakhiwa kwizicwili kunye intlala. Occipital, ithambo ngokungqalileyo kunye nezinye izinto ziqulathe amacandelo eziliqela. Xa Iikona iziqalelo amathambo usana entloko akukho amazinyo. Ngoko ke, lo uxhulumaniso lusenziwa ngokusebenzisa imicu inwebu nokuqina kwaye akukho ezivuzayo. Kwiindawo apho engile toe lweziqalelo ithambo eziliqela, yenza okufanayo inwebu bokwakha fontanels.

Ngophuhliso umntwana lwenzeka nokuzicacisa amathambo ezithile-nye, ukuyilwa sutures, fontanelles yene. Ngoko ke, ngokuthe ngcembe kugqitywe inkqubo Ukuqina, ukukhula amathambo.

Amathambo entloko, ngokunjalo, kwaye umzimba uphela, kuyo yonke yobomi bomntu iyatshintsha. Ngoko ke, iminyaka emashumi mathathu, njengoko umthetho, inkqubo amalungu overgrowing iqala. Emva kokuba umntu ubudala, amazinyo aqalise iwe kwaye shwaka i iseli ababehleli kuyo.
