Kodi chigaza msoko ndi zaka?

chigaza cha munthu si zofunika kwambiri fupa mapangidwe, komanso kwambiri zowoneka otchuka. Choncho, yofanana ake onse sindingakhoze kupita padera. Magawo a kusinthika wachibale kwambiri ndipo munthu aliyense ndi wapadera, koma pali mfundo zikuluzikulu zochokera zaka.

Pa moyo wa chigaza cha munthu wadwala zosiyanasiyana kusintha. Kwenikweni za maonekedwe ake. Conventionally, pali nthawi aakulu asanu kusintha. Tiyeni tikambirane mfundo iliyonse ya zimenezi mwatsatanetsatane.

nthawi yoyamba

Nthawiyi ndi gawo ambiri yogwira kukula kwa mutu ndi kumatenga zaka zisanu ndi ziwiri za moyo. Chibadwire miyezi isanu ndi umodzi, pafupifupi amawonjezera buku neurocranium. Ndi zaka ziwiri, buku wake katatu, ndi zaka zisanu ndi zitatu kotala ya chigaza lonse. chiŵerengero Izi anakhalabe moyo. Zinali nthawi imeneyi ndi sankangotanthauza cranial fossa, ndipo kumbuyo kwa mutu akuyamba kulankhula. Komanso, minofu membranous ya m'chipinda chotetezeka cranial ndi minofu cartilaginous mu fupa occipital mutate ndi zayamba kutha. Zimachitika choyamba (gawo loyamba) wa n'kupanga mafupa a msoko mutu. Nthawiyi ndi zofunika kwambiri, chifukwa chigaza msoko si kophweka kukapempha mafupa a m'mutu ndi mzake ndi, Chofunika kwambiri, ndi malo a kukula m'lifupi.

Gulu la sutures cranial

Sutures ali m'magulu malinga ndi maonekedwe awo zotsatirazi:

• imodzi;
• wazikang'a;
• mosabisa.

Imodzi chigaza msoko popangidwa ndi pamalo awiri fupa pamene munthu ali zolosera, ndi pa zina - mphako kudzaza zolosera izi. Izi mtundu zimfundo ndi cholimba kwambiri. Ndi overlaying mbali ziwiri mafupa pafupi flake anapanga chigaza suture. matabwa onse ali odzazidwa ndi minofu connective kuti amalimbitsa ndi kuyenda mankhwala amenewa. Ndipo mtundu wachitatu wa welds - mosabisa. Lathyathyathya chigaza suture anapanga anakumana pang'ono wavy kapena kwathunthu mosabisa pamalo fupa. Ndi mtundu uwu wa kugwirizana msoko amapezeka mafupa nkhope pakati pawo, ndipo dzina lawo zimadalira inakula mapangidwe fupa.

The kusintha chachiwiri nthawi

Patapita zaka zisanu, mafupa a m'mutu ndi kukula mochuluka pang'onopang'ono. Zimachitika zowoneka kwambiri noticeable kusintha mu kukula ndi mawonekedwe a mbali kutsogolo kwa chigaza (kanjira, ndi m'mphuno ndi maxillary). Tatseka ngakhale ndi neonatal nthawi fontanelles kutha kwathunthu, ndi zimfundo ndi wodzazidwa ndi connective Tacna.

nthawi yachitatu

Nthawiyi chikugwirizana ndi munthu akutha msinkhu ndi kumatenga zaka khumi (osiyanasiyana zaka 14-15 zakubadwa kwa zaka 25). Iwo ubwera chomaliza chigaza kukula ndi onse a mafupa ofananira. Mu nthawi imeneyi (mosiyana ndi m'mbuyomo awiri) ndi zambiri tima kukula kwa chigaza nkhope, osati ubongo. The suture a chigaza monga mapangidwe anatomical amakhala cholimba, ndipo amayamba nthawi ossification, amene kumatenga mpaka kukalamba. Kuwonjezeka m'munsi Chibade cha mbali zonse, osati lonse. Potsiriza anapanga grooves, zitunda, tokhala ndi sinuses pneumatic.

Nthawi chachinayi

Kuyambira zaka 25 mpaka 45 palibe kusintha mu mafupa a chitukuko mutu. Nthawi imeneyi, chigaza msoko ossified. Nthawi zina kwambiri, malo kungapitirire moyo.

The nyengo yachisanu

Siteji imeneyi imatenga kwa zaka msoko imperforate wokalamba. Zimachitika kuti kusonyeza kwambiri kusintha anatomical, ndi structural. Zowoneka anasintha nkhope chigaza chifukwa dzinolo ndi manja a njira alveolar. Ndi zaka, makulidwe a yafupika cancellous ndi yaying'ono mbale ndi chigaza mosavuta. Chifukwa cha fupa resorption ndi mchere fupa samasintha dongosolo wake umakhala Chimaona, mng'alu ndi yopuma.

Pomaliza

Anthu Chibade - otchedwa mafupa mutu. Mlatho anatomical n'chofunika kwambiri osati kuteteza ubongo ndi ziwalo imalandira. Iwo amayambanso maonekedwe athu (nkhope).

The msoko a Chigaza, monga gulu dongosolo-zinchito amagwira ntchito yofunika kwambiri mu kulumikiza chigaza mafupa pamodzi. Mu ana, matabwa ndi kusinthasintha kwambiri, koma ndi zaka iwo ossify.

Magawo chitukuko cha mafupa a Chigaza ndi zaka malire. Choncho, neonatal nthawi, ngakhale pamene fontanels kusungidwa (membranous siteji), anthu anapeza chichereŵechereŵe kusasitsa mu sitepe, ndipo kenako mu fupa.

Ndi nthawi ya kubadwa si anamaliza ndi mapangidwe a Chigaza lapansi. Pali magawo asanu a chitukuko. Choncho, kuchokera pa kubadwa kwa zaka sukulu (zaka 6-7) chigaza amalima makamaka msinkhu, zaka zisanu ndi zisanu ndi ziwiri ndi nthawi mwamtendere, ndi isanayambike kutha msinkhu ndi zaka 25 zakubadwa zimachitika zosintha makamaka mbali kutsogolo.
