Yevanhu dehenya

Human dehenya ndiwo marangwanda yomusoro wake. Share marangwanda ichi pamberi uye pfungwa nhengo.

Munzvimbo kuuropi ari muchimiro musoro marangwanda pedyo bhora. Sechivako chikamu ichi chine mbiri parietal, frontal, occipital, epanyama, uye vamwe vaviri mapfupa yeDehenya wemunhu. By mhando zvinhu zvose zvakakwana gobvu curved mahwendefa. Izvi zvinonzi mapfupa sandarara. Basa ravo kuitira kudzivirira uropi kubvira kukuvara.

Nomumwe zvinhu pfupa riri marangwanda remusoro vari vakabatana vazvo. vagari iyi inonzi mira. weld inotungamirwa rinoitwa kuenzana micheto maviri pedyo zvinhu. Muchiitiko chino, akagura umwe wavo rinosanganisira zvimwe mazino.

dehenya hwomunhu muuropi mugove ane pose hwaiva kumeso (divi uye pamusoro). Mujinga uropi akafukidzwa hadzina kufambiswa zvakanaka uye maberere siyana. Izvi imhaka ndechokuti dehenya dzevanhu munzvimbo iyi chokuita tsandanyama fibers. Mujinga anewo mawindo. Kuburikidza navo kupfuura manzwiro nemidziyo ropa. Inenge iri pakati chikamu marangwanda ari musoro uri yakakura (occipital), mauri kubatana ndiro uropi uye musana.

Pamuganhu kurutivi hukawanika uye mujinga dehenya yaiva auditory orifice (yokunze). The pasi pemvura occipital mapfupa nhengo ane articular pezvakaitwa izvo okurutivi mativi ose foramen magnum. With azvaiitwa yeDehenya kwevanhu zvakabatana nomuzongoza.

Nzvimbo pamberi marangwanda ari musoro chinosanganisira peya mhou nemamiriro okunze. Izvi zvinosanganisira maxillary, nasal, zygomatic, palatine, uye dzimwe mapfupa. Mandibular pfupa chaikosha haisi aiwanzopiwa wokushanda.

Munzvimbo pamberi marangwanda remusoro vanosarudzirwa muromo, mhuno, uye ziso nezvigadziko.

Hollow rinoratidza yakadzika mwoyo. Mariri nhema yeziso dzaro tsandanyama, tsinga uye utano hwake.

The nasal mhango anovhura pamberi buri pechiso musoro marangwanda. Zvinokonzera nasal mhango zvakabatana kuti pharynx achishandisa makomba maviri. The rworudyi uye rworuboshwe hafu mhango vari inoumbwa partitions vachigoverana mafupa. In neimwe hafu nasal ndima dziri inoumbwa mapfupa matatu.

The zvokuudzwa mhango anosiiwa yepamhino achibatsirwa ari palatine mapfupa zvinhu uye pezvakaitwa ari maxillary mapfupa. Kumicheto rezasi uye okumusoro shaya kukurambidza muromo laterally.

The dehenya yevanhu chete nhengo uye zvenyaya marangwanda pakati mhuka musoro. Zvisinei, chinhu chinokosha chinowanikwa musoro marangwanda kwavanhu chikamu zvakanaka zvikuru-dziridza uropi. In mhuka, zvikuru dzakabudirira chikamu mberi.

The zvinhu anoumba achangoberekwa dehenya dzevanhu vachingotya kukwana Ossificação em. Ivo rinoumbwa connective zvinyama uye shwashwa. Occipital, frontal pfupa uye zvimwe zvinhu zvine akawanda zvinoriumba. At kumicheto pezvokuvamba marangwanda ari vachangoberekwa musoro hapana mazino. Saka, kubatana chinoitwa pachishandiswa micheka yakatsemurwa connective membranes uye hapana vazvo. Munzvimbo chigunwe pamakona anoverengeka mapfupa okunze, wedzerai Kamudzira zvichiumba fontanels.

With kukura mwana kunoitika nekunyatsotsanangura nemumwe vamwe mapfupa, paumbwe sutures, fontanelles vashoma. Saka, rakazopera Ossificação em muitiro, mapfupa kukura kunotanga.

The marangwanda musoro, pamwe, uye muviri wose, yose youpenyu hwevanhu ari kuchinja. Saka, pamwe matatu, ari kutonga, muitiro overgrowing majoini inotanga. Paaizosvika zera munhu, mazino anotanga kuwa panze uye Zvibvisike sero mavakanga vagere.
