Isakhiwo Yekhanda womuntu. Lona kanye uhlobo ukucabanga ...

skull lomuntu liwumsebenzi omuhle bony ibhokisi eziyinkimbinkimbi ukucushwa ukuze ihlanganise ubuchopho kanye receptor sezinzwa ehambisana ne-ubuchopho ngqo: iso - iso, indlebe - amabili umamukeli umsindo yangaphandle kuhambisane elingaphakathi maphakathi nendlebe, ekhaleni - ekhaleni ngeziteshi ezimbili futhi ingaphakathi maxillary, ukunambitheka - receptor esisogwini ulimi. ethintekayo Imininingwane noma Haptic, ethathwa ubuchopho umlamuleli.

ngokuhlukana obusebenzayo

womuntu skull isakhiwo ngendlela enomqondo, efana nakho konke okunye ngokwemvelo. Brain ekamelweni ithatha wonke engxenyeni engenhla kogebhezi Ezansi yakhelwe ukuze ihlanganise izitho visceral. Brain ingxenye siqukethe eziningana pair eyodwa amathambo zixhunywe amalunga omzimba. Lokhu frontal, parietal futhi occipital amathambo, namathambo abhanqiwe - nhlonhlo futhi yesikhashana. ingxenye Visceral kuhlanganisa i ongenhla futhi ephansi igobolondo ekhaleni, ulwanga futhi ithambo zygomatic, a mandible futhi ithambo hyoid.

visceral ingxenye

Ugebhezi yokungena evulekile wokugaya ukudla namapheshana zokuphefumula. Ezithathekayo ingxenye Yekhanda, umhlathi ongezansi, ophela emphinjeni, wedlula emphinjeni nomphimbo. Ngakho, isakhiwo Yekhanda womuntu igxile empilweni wonke umzimba. Lezi abamukelayo ezimbili kukhona ukudla emoyeni ehlukana nokuthi ngamunye wenza umsebenzi walo. Skull kwesisekelo salo uhlezi phezu emgogodleni, isekelwa yi amathambo eziyisikhombisa wesibeletho, baphinde badlale indima luhlaka usekelo entanyeni imisipha, ekhipha igazi enhliziyweni nelifakayo. Sidlula phansi omningi, ekupholiseni izinzwa, ngamunye wabo kuletha kuze kuyofika emnkantsheni ingxenye yakhe ulwazi ekuphenduleni ethola amaza ezidingekayo. Kunalokho isakhiwo eziyinkimbinkimbi Yekhanda womuntu ulungisiswa eziningi imisebenzi ewusizo.

egumbini

Ingxenye engenhla - okubizwa ngokuthi lwaleli, phambi lwaleli - ebunzini, amashiya labona phakathi esemgwaqweni ikhefu. Ohlangothini ugebhezi egumbini eduze ngamunye ithambo yesikhashana, parietal futhi umbhalo we-cuneiform amathambo. Phansi umehluko phakathi kwala mathambo iqala base Yekhanda. Ifomu base eziyinkimbinkimbi, inani elikhulu Imigudu ezahlukene okuyinto qhaqha yezinzwa kakhulu futhi imithambo yegazi. Ngesikhathi ingxenye ezingemuva base elise ithambo occipital. Ngezindlela eziningi, isakhiwo Yekhanda womuntu kungaphansi lezinkinga yini nokusekela ukuphila kwakhe.

phambi ingxenye

Ngaphambili okuyingxenye Yekhanda yakhiwa imikhakha emithathu, sihluke nomunye, engahlobene futhi imisebenzi ezimele. Lokhu orbit - pair kwetinhlavu ngesimo nendawo ngokufanele nibonakala base mbhoshongo, beyizidalwa eziphakeme kunazo ngaphakathi. Skull ithambo lomuntu isakhiwo sangaphakathi amasegimenti - konke eziklanywe ngokucophelela futhi oxhumene. Isokhethi iso ibekwe inhlamvu yeso nezindlala ezikhiqiza uketshezi izinyembezi, futhi ethile amafutha. Ngezansi uMnyango Iso ingaphakathi acinene itholakala maphakathi. Phakathi ithambo ingaphakathi lihlukaniswe by ukwahlukanisa, futhi ivula ngaphandle, imbobo ipheya emise. Konke lokhu kungabonwa uma ubheka isakhiwo Yekhanda wobuntu izithombe. Ngezansi ngalo ingaphakathi acinene kuyinto ngalo ingaphakathi ngomlomo, le-alveoli futhi okuyinto iphahlwe nemengamo singatsheki zamazinyo kwamathambo bhakabhaka phezulu. I ngalo ingaphakathi ngomlomo ingxenye ezihambayo kakhulu Yekhanda, ethwele ukuhlafuna umsebenzi. Ngaphezu kwalokho, e-ngalo ingaphakathi ngomlomo kuyinto umshini izwi.
