Farantin kashi nufin da kwakwalwa sashen. A wasu sassa cewa yin up da ethmoid kashi na kwanyar, suna da hannu a cikin samuwar gefen tsakiyar ido kwasfansu, da hanci kogo katangu.

Takamaiman raya farantin articulates tare da Tapered kashi. A gaban da kuma a kan bangarorin da shi ne a haɗe zuwa frontal kashi. A kan farantin da wani jam'i na takware ne ba. Suna yi nufi ga nassi na matakai olfactory jijiyoyi. A cikin tsakiyar layin da farantin kara zuwa gaba don haka ya kira cockscomb. Ya aka shiga a gaban karshen wani cerebral lauje. A gaban da kunya ainihin guda biyu appendage - reshe. Perpendicular kyakkyawan farantin yana da wani sababbu siffar. Yana Forms da gaban yankin na hanci septum.

labyrinth

Its Kwayoyin kasu kashi uku kungiyoyin. Sun rabu da juna, amma ba a fili. Ware da baya, a gaban kuma a tsakiyar kungiyar. A cikin kaikaice gefen bakin ciki orbital farantin inuwõyi. An daidaitacce zuwa kogo da kewayewa ta free surface. Daga ciki, kawai karamin sashi daga cikin cell da aka rufe da fitar kasusuwan jikinsu faranti. Mafi yawansu ba su zauna a bude. Su rufe da m frontal, Palatine, lacrimal da sphenoid kashi da babba muƙamuƙi.

Gefen tsakiyar na labyrinth fassara da babba yankin na hanci kogo. Yana yana da biyu na bakin ciki farantin - harsashi (tsakiya da kuma na sama). Akwai kuma wani ƙugiya-dimbin yawa appendage. Akwai rata tsakanin nutse - wannan shi ne babba hanci nassi. Bayan da kuma dan kadan sama da babba sako, a wasu lokuta, shi ya tarar da wani - mafi girma. Bawo wanda ya hada da a cikin abun da ke ciki ethmoid kashi na kwanyar, sauye a size da kuma siffar, ma'ana wani daban-daban tsawon kuma zurfin Game da hanci Tsarki.

shugaban kwarangwal rufin

Girman kwanyar vault a cikin agara frontal convexity ne. Yana yana tadawa: Brow ridges da tudu. Rear rufin Forms da occipital kashi. A kowane gefen ta short parietal abubuwa. Daga cikin zygomatic aiwatar da frontal kashi a kan rufin boko gudanar arcuate line. Yana ƙuntatãwa saman rami, wanda a nuna rarrabe infratemporal dagi daga wannan tsagi.

fili abubuwa

Alaƙa kwanyar kashi (tebur a kasa a takaice ya nuna da iri connection) ci gaba ga mafi part. The main iri suna abutting da synchondrosises syndesmoses. Ƙananan muƙamuƙi an haɗa temporo-mandibular hadin gwiwa, da kuma sublingual memba - ta hanyar tsoka zaruruwa. Syndesmoses wakiltar fibrotic sanarwa akan abinda a da dama seams. Matsayin mai mulkin, su sunayen suna kafa da bi ta haɗu ƙasũsuwa. Duk da haka, akwai seams wanda suna da nasu sunayen. Alal misali, da sanarwa akan abinda da parietal ƙasũsuwa sanya ta sagittal, frontal da parietal - coronal dinki da sauransu.

Synchondrosises gabatar a matsayin guringuntsi mahadi. Aka sãme su, yafi a girman kwanyar tushe. Jariri syndesmosis gabatar da connective nama membranes. Su kira fontanelles.
