Ndi nembanemba ubongo Kodi

Ubongo wa munthu ndi chiwalo cha dongosolo chapakati mantha, chomwe ambiri njira zogwirizana maselo mitsempha ndi udindo ntchito zonse za thupi. Cranial M'mimbamo dipatimenti, imene muli medulla, kuteteza mafupa asatengere kunja mawotchi. Ubongo, komanso chingwe msana, yokutidwa ndi nembanemba atatu: molimba, zofewa ndi arachnoid, omwe amagwira ntchito yake.

kapangidwe Dura

Chokhalitsa olimba chipolopolo ubongo ndi wandiweyani cranial periosteum, amene ali likhale lolimba. Pamwamba lamkati la chipolopolo ali zokhudzana angapo kudutsa mu zakuya ubongo kudula kwa m'madipatimenti osiyana. Yaikulu ya ndondomeko otere lili pakati pa hemispheres awiri, kusonyeza kufanana zenga zapambuyo gawo lomwe merges ndi snaring cerebellum ndi kukuchepetsa izo kwa lobes occipital. Pa padziko nembanemba wandiweyani ubongo, pali ndondomeko wina amene aikidwa padziko lapansi sella turcica, kupanga mtundu wa kabowo ndi atetezedwe ku kwambiri pituitary ubongo misa kuthamanga. Pa mbali ziwalo ndi sinuses wapadera, wotchedwa sinusitis, lomwe limapezeka venous Reflux.

Kapangidwe ka arachnoid ubongo mutu

Arachnoid ubongo chipolopolo ili mkati chipolopolo zolimba. Ngakhale kuti anali woonda kwambiri ndi mandala, koma kudutsa mu ming'alu ndi grooves hemispheres nthawi yomweyo kuphimba nkhope yonse ya thunthu ubongo, ndipo amayenda mbali wina ndi mzake. Kuyambira Kakhungu cerebrovascular arachnoid alekanitsa danga subarachnoid, wodzala ndi madzimadzi cerebrospinal. Kodi mthunzi ili pa grooves kwambiri padziko lonse, malo subarachnoid amakhala onse, kupanga zosiyanasiyana zamitundu thanki. Pamwamba mbali otukukira kunja, makamaka pamwamba convolutions ndi, zikopa zofewa ndi arachnoid ubongo sitingalephere mbamuikha wina ndi mzake, choncho danga subarachnoid m'maderawa kwambiri mwapang'ono ndi kusiyana capillary.

Mayina a zitsime zikuluzikulu subarachnoid:

• cerebellar-oziziritsa nkusani ili mu poyambira pakati pa cerebellum ndi malo lili ndi medulla oblongata ;
• mabowo nkusani lateral ili mbali m'munsi mwa hemispheres oziziritsa;
• chiasm thanki ukugwira ntchito pa woyambira mutu, ndi pamaso pa chamawonedwe chiasm;
• Kutanthauzira interpeduncular thanki - pakati pa miyendo ya ubongo fossa interpeduncular.

akalowa ubongo ndi connective minofu nyumba, amenenso kuphimba ubongo ndi msana. Iwo amagwira ntchito chitetezo, kulenga gistogematicheskie, likvorotkanevy likvorogematichesky ndi zopinga zimene zogwirizana kagayidwe ndi outflow wa mankhwala cerebrospinal. Popanda nyumba izi sizingakhale uziyenda yachibadwa ya ubongo ndi madyedwe chokwanira zinthu zake zonse.
