Iimpawu Age intamo. Skull baby. Le sutures intamo: Anatomy

Ukucacisa indima kusekwe kwaye ezilandelayo uphuhliso yokakayi bobabo zobuchopho, amazinyo, ukuhlafuna izihlunu kunye namaziko nemizwa. Ngexesha ukukhula intloko ivavanywa utshintsho olubalulekileyo. . Ngexesha kuphuhliso ibonakale ubudala, isini kunye neempawu ngamnye intamo. Cinga ezinye zazo.

kubelekwa

имеет специфическую структуру. Skull usana isakhiwo ethile. Isithuba phakathi kwezakhi nangamathambo lenza zeethishu nokuqina. Xa kubelekwa, ayikho ngokupheleleyo sutures ukakayi. этой части тела представляет особый интерес. Anatomy of the umzimba umdla ethile. Kumacandelo kokuxhuma ithambo eziliqela fontanels 6 langoku. ikhava nokuqina nembasa. Kukho iindidi ezimbini unpaired (ngasemva kunye ngaphambili) ngambini (mastoid, tapered) fontanel. Kucingwa ebunzi inkulu. It has a imilo kwedayimani. Sikhoyo kwindawo Ukuhlanganiswa ngokungqalileyo asekhohlo nasekunene yaye zombini amathambo Parietal. очень эластичен. Ngenxa fontanelle skull umntwana elastic kakhulu. Xa intloko olungekazalwa udlula emjelweni wokuzalwa, imiphetho nophahla ziyadibana imbricate. Ngenxa yoko, oku kunciphisa. Ngeminyaka emibini, ibe umthetho, akhiwa ngayo sutures yokakayi. раньше изучалась довольно оригинально. Anatomy ngaphambili wafunda kakhulu yokuqala. YooGqirha Middle isicelo entsimini fontanels ngentsimbi eshushu izifo iliso, nobuchopho. Emva kokumiselwa kukuqulungana unobangela suppuration oogqirha ezahlukeneyo ukubacaphukisa arhente. Ngoko bakholwa ovula indlela baba izinto eziyingozi. Kuqwalaselo beentanda uthi bazama ukwenza ngaphandle abalinganiswa, iileta. Oogqirha bakholelwa ukuba ulwazi malunga kwekamva yomguli wayelele phantsi kubo.

isakhiwo Iimpawu skull

Le yinxalenye yomzimba usana kuba yayimfutshane ngesithomo amathambo ebusweni. Enye inkalo ezithile fontanels ikhankanywe ngasentla. Xa skull usana iphawulwe tracks zonke 3 izigaba kwamathambo ayiphelelanga. Fontanelles - iintsalela kwexesha membranous. phambi kwabo kubaluleke pfunaka. Baya ikuvumela ukuba uhambise amathambo eluphahleni. SobuKristu fontanelle ibekwe ecaleni komgca median kwikhompawundi-nezidibanisi 4: 2 iihafu coronal, sagittal kunye ngokungqalileyo. Ekhula ngomnyaka wesibini ebomini. Le fontanelle elingunxantathu diff. Le ibekwe phakathi amathambo amabini Parietal ngaphambili nangasemva esikalini ithambo entanyeni. Ekhula ngenyanga yesibini. Le fontanelle lateral ukwahlula nesinqumka kunye mastoid. Imvelaphi kwi toe isabelo Parietal, ngokungqalileyo, isikali zexeshana kunye nephiko olukhulu wethambo sphenoid. Oku amila ngenyanga yesibini okanye yesithathu. fontanel Mastoid ibekwe phakathi isiseko ithambo Parietal zepiramidi kwi zexeshana kunye Occipital.

isigaba cartilaginous

Kulo nyathelo bobona budala zilandelayo ingakumbi ukakayi. Phakathi izinto angagqithanga edidekile ibhaqe cartilaginous kwesiseko bone umaleko. sinuses womoya nje kodwa kuphuhliswa. Ngenxa yobuthathaka izihlunu nasentshonalanga izihlunu ezahlukeneyo, amaqhuma kunye imigca ababuthathaka. Ngenxa yesizathu esifanayo, ezinxulumene nayo nokungabikho umsebenzi ukuhlafuna, umhlathi ngokwaneleyo. iinkqubo Alveolar phantse namnye. Imihlathi esezantsi ke ngoko yabhalwa weziqingatha 2 ununited. Ngenxa yoko umntu encinane iza phambili ngokuphathelele ukakayi. Yinxalenye 1/8 kuphela. Kulo mzekelo umlinganiselo ubuso abadala kunye ukhakhayi - 1/4.

Ukubana emathanjeni

iimpawu Age of the ukakayi emva kokuzalwa siwubona nemingxuma ukwanda esebenzayo - ngeempumlo, ingqondo, ngomlomo kunye ngeempumlo. Oku kukhokelela ukubana emathanjeni angqonge nabo kwicala njengezazisi ukukhula. Ihamba kunye ukwanda ubude ubukhulu. Xa yommandla kunye ugobile ukukhula phezu amathambo iqala ukutshintsha.

kokuzalwa komntwana

проявляются в неравномерном росте лицевого и мозгового отделов. Kweli nqanaba, iimpawu ubudala ukakayi ebonakaliswa Ukukhula ngokungalinganiyo amacandelo zobuso kunye nedumbe lengqondo. Ubukhulu yomgama ngabaya linyukile ngo-0.5, kwaye yokuqala - ngamaxesha-3. Umthamo yesebe yobuchopho kwiinyanga ezintandathu zokuqala kabini, yaye kunyaka wesi-2 - kathathu. Iminyaka 7 wokukhula kuyehla xa ufikisa ibalekisa kwakhona. Ngeminyaka 16-18 uphuhliso iseti yokuma. Isiseko yaligqiba ubude, ukuya kutsho kwiminyaka 18-20 lize liphele xa wokuvala nesinqumka-Occipital synchondrosis. Ukukhula kummandla yobuso umdana kwaye iyunifomu. Eyona ngenkuthalo ekhula ithambo emlonyeni. в процессе роста проявляются в срастании частей костей, разделенных у новорожденных, дифференцировке в структуре, пневматизации. Age features skull ngexesha lokukhula wabonakaliswa kwiindawo intergrowth amathambo ngokwahlukana umahluko lweentsana kubume, umxholo umoya. Umfanekiso imiphezulu yangaphakathi langaphandle uba esicaciswe ngakumbi. Esemncinane kwi the seams kwakhiwa edge ngqo, iminyaka engama-20 zezilwanya uxhulumaniso unamazinyo.

linqanaba lokugqibela

E amane iqala obliteration of sutures. Iquka yonke okanye uninzi imichiza. Ebudaleni bakhe kwamathambo saka kumakishwa amathambo cranial. Iqala amacwecwe thinning of kweziyobisi compact. Kwezinye iimeko, kukho ukuqina emathanjeni. Yoma kwi alveolar uba ucaca ngakumbi kummandla yobuso ngenxa kwamazinyo. Oku kubangela ukwanda engile le mandible. Ngenxa yoko, kwesilevu iya phambili.

isini

Kukho iindlela ezininzi apho inkunzi yohlukile ukakayi ababhinqileyo. Ezi mpawu ziquka ngesidanga uburhabaxa kunye tuberosities ezindaweni kuthinjwe izihlunu, uphuhliso mastoid kunye Occipital nesisu yangaphandle, imidlalo kwemihlathi yangasentla njalo njalo. Ukhakhayi Ubudoda iphuhliswa ngakumbi xa kuthelekiswa imazi. Icacisa emboxo ngakumbi ngenxa yengxinano nengcinezelo oluya uburhabaxa kunye neendawo bahambe ezindulini ukuba athimbe ukuhlafuna, zezomzuzwana, Occipital kunye nezihlunu nentamo. Frontal kunye Parietal hillocks zophuhliso kakhulu kwabasetyhini, ebantwini - glabella nebunzi emikhulu. yokugqibela inzima kwaye ezinkulu kuno emhlathini asezantsi. Xa kummandla ezinemiphetho ezisezantsi kunye neekona ingxenye engaphakathi kusesilevini ichazwe ngokucacileyo tuberosity. Oku kungenxa yokuba i-attachment ye digastric, masseter kunye nezihlunu pterygoid. Kuxhomekeka bobulili ezahlukeneyo kunye imilo ukakayi yabantu. Amadoda ibhiyozelwa ibunzi kophahla, nto leyo iba isithsaba ajikelezayo. Kudla kukho ezintabeni kwicala suture sagittal. Ebunzini abafazi nkqo ngakumbi. Yena eshenxela isithsaba flat. Ngabantu, iliso socket ephantsi. Ngenxa umthetho, ukuba ziyinxalenye yebala mazimile buxande ukumila kakuhle. Umda wabo eliphezulu eqinileyo. Kwabasetyhini, neziseko iliso zibekwe ngentla. Ukuba basondele ukuba seqanda okanye ngeenxa kunye kudini libukhali kwaye thinner eliphezulu. Kwi skull wabafazi ithambo alveolar kwi kwemihlathi yangasentla liza phambili. Nosolobny engile emadodeni luboniswa uninzi amatyala ngokucacileyo. Kwi-female ukhakhayi ngokungqalileyo ithambo kwi ingeniso isaphetha ngakumbi kakuhle.

ukwengeza

imilo skull yabantu akuthethi echaphazela umthamo engqondweni. Ngokutsho iziphumo zophando emininzi zesayensi sinokugqiba ukuba kukho nasiphi na isizathu sokukholelwa ukuba nasiphi na uhlanga esilawulwa ubungakanani kwisebe lobuchopho. I ngabaThwa, awafane kunye nezinye izizwe ubukhulu intloko mncinci kancinane kunalowo abanye abantu. Oku kungenxa ngesiqu encinane. Rhoqo ukuhla intloko inokuba kuba sisiphumo ukungatyi kangangeenkulungwane kunye nempembelelo kwezinye izinto ezimbi.
