saxan interlink ee dhakada - 2 godad

Laba godad saxan toosan waa nidaam la hagaajiyay, oo dhamaystiran oo bixiya dabacsanaan, sahlan isticmaalka, iyo qalab tayo sare leh oo lagu dhejiyo.Astaanta saxan-maro-hooseeya ee 0.5 mm ee la taaban karo maqaar-gaabeedka ugu yar.Nidaam qalab oo kali ah oo loogu talagalay hagaajinta degdega ah ee xasilinta ee lafaha cranial.

Dhafoorku waa qaab-dhismeed lafo ah oo ka samaysan madaxa laf dhabarta.Lafaha qalfoofka waxay taageeraan qaababka wejiga waxayna bixiyaan dalool difaac ah.Dhafoorku wuxuu ka kooban yahay laba qaybood: cranium iyo mandible.Labadan qaybood ee bini'aadamku waa neurocranium iyo qalfoofka wejiga oo ay ku jiraan mandible oo ah lafteeda ugu weyn.Dhafoorku wuxuu ilaaliyaa maskaxda, hagaaji masaafada labada indhood, hagaaji positon dhegaha si ay awood ugu yeeshaan meelaynta dhawaaqa jihada iyo fogaanta dhawaaqyada.Caadi ahaan ku dhaca natiijadu dhaawac xoog leh oo badheedh ah, jabka lafta madaxa ayaa laga yaabaa inay noqoto jebin mid ama qaar ka mid ah siddeedda lafood ee samaysa qaybta cranial ee madaxa.

Jab ayaa laga yaabaa inay ka dhacdo ama agteeda goobta ay saamaysay iyo waxyeelada dhismayaasha hoose ee madaxa sida xuubabka, xididdada dhiigga, iyo maskaxda.Jabka madaxa ayaa leh afar nooc oo waaweyn, toosan, niyad jabsan, diastatic, iyo basilar.Nooca ugu caansan waa jabka tooska ah, laakiin looma baahna in la sameeyo faragelin caafimaad. Sida caadiga ah, jabka niyad jabsan waxaa badanaa lagu gooyaa lafo badan oo gudaha ah oo jabay, markaa waxay u baahan yihiin faragelin qalliin si loo hagaajiyo dhaawaca unugyada hoose.Jabka diastaatiga ahi waxa uu ballaadhiyaa tolida dhakada dhafoorka carruurta da'doodu ka yar tahay saddex sano.

Jabka madaxa oo niyad jabsan.Dube lagu dhufto, dhagaxa ama madaxa oo lagu laado iyo noocyada kale ee dhaawac ba'an ayaa badanaa keena jabka madaxa oo niyad jabsan.11% dhaawacyada madaxa ee daran ayaa ku dhaca noocyadan jabka ah ee jabka jaban ee lafaha jabay ay gudaha u galaan.Jabka madaxa ee niyad jabku waxa uu keenaa khatar sare oo ah cadaadiska maskaxda oo kordha, ama dhiigbax maskaxda oo burburiya unugyada jilicsan.

Marka uu jiro jeexan ka sarreeya jabka, jabka madaxa ee isku dhafan ayaa dhici doona.gelinta daloosha cranial gudaha ee xiriir la leh deegaanka dibadda, kordhinta khatarta wasakheynta iyo caabuqa.Jabka murugsan ee kakan, dura mater waa jeexjeexay.Qaliin waa in lagu sameeyaa jabka madaxa ee niyad jabsan si lafaha maskaxda looga qaado haddii ay ku cadaadinayaan iyada oo godad daloola laga sameeyo madaxa caadiga ah ee ku xiga.

Dhafoofka bini'aadamka wuxuu u kala qaybsan yahay laba qaybood: Neurocranium, oo ay sameeyeen siddeed lafood oo cranial ah oo guriga ku jira oo ilaaliya maskaxda, iyo qalfoofka wejiga (viscerocranium) oo ka kooban afar iyo toban lafood, oo aan ku jirin saddexda ossicles ee dhegta gudaha.Jabka madaxa ayaa sida caadiga ah loola jeedaa jabka neurocranium, halka jabka qaybta wajiga ee dhafoorka uu yahay jabka wajiga, ama haddii daanka uu jabo, jab mandibular ah.

Siddeed lafood oo cranial ah ayaa loo kala saaraa tolmo: hal lafo hore, laba lafo parietal, laba lafo ku meel gaar ah, hal laf occipital, hal laf sphenoid, iyo hal lafo ethmoid.
