Ithambo nomsi-. Driving ithambo cancellous. Ubume ithambo cancellous

Amathambo Umntu unamathambo ngaphezulu kwama-200. Bonke ukwenza umsebenzi okhethekileyo, jikelele, ukudala inkxaso izibilini zangaphandle nezangaphakathi. Kuxhomekeka umthwalo kunye nendima umzimba, kukho iintlobo ezininzi.

amathambo

Xa uhlobo owomileyo ithambo 1/3 iquka izinto eziphilayo - osteina protein. Yena unika ukuba bhetyebhetye nokuba luthambe. 2/3 - ezi iityuwa calcium ezingaphiliyo, ngenxa apho amandla alo kuyafikelelwa.

Iqokobhe zangaphandle into ebizwa ngokuba yi-compact. Oku Imihlubulo zamahlathi kwithishyu esisodwa. Umaleko densest kubo bunokubonwa embindini amathambo elide. Ezi imiphetho into compact iba thinner.

Ngokuxhomekeka kuhlobo amathambo yangaphakathi inxalenye yawo anokuba nokuba lithambo cancellous, okanye ukusuka lomongo wethambo emhlophe, okanye abe nomoya. ithambo nomsi-, ukongeza, kusekho kunye wamathambo ebomvu.

Xa iziphelo ithambo ezi luvo kunye imithambo yegazi adibanayo ngayo yonke inyama nokubonelela isondlo, ukukhula kunye nokulungiswa.

Iintlobo ze amathambo umzimba womntu

Xa isakhiwo ithambo iyahlulwa ibe nomsi-, ityhubhu kunye Ukusebenzisa umoya. Tubular ibizwa nayo ixesha elide. Zikhona kuphahla lomzimba kwaye intshukumo yabo. La mathambo enziwe into compact kunye lweHo- ezaliswe wamathambo ebengezelayo. Xa iziphelo kubo into encinane nomsi- ezaliswe wamathambo ebomvu.

Nomsi- ithambo ngokupheleleyo yimbali bone cancellous kunye lomongo wethambo ngaphakathi, ukuba ikhuselwe ngento compact. Bakha kwikhavithi (thoracic, cranial) kwaye abe inkxaso kwimimandla umthwalo omkhulu (yomqolo, phalanges).

ithambo womoya nibagqithile ngokwesakhiwo esithile: into compact ngaphakathi umngxuma, sweetening epithelium kunye nomoya. Njengoko umzekelo inokuba kuchazwe maxilla skeleton.

Bone nomsi-: scheme eneenkcukacha

Njengoko sele sibonile, nto leyo ethe Isakhiwo ithambo cancellous Oku akukho kwahluka kwabanye. Le kwisisu kwakhiwa compact kwaye zigcwaliswe kunye nempahla nomsi-. Ngu imvelaphi zahluke. imiphetho Bone, umzekelo, lithatyathwe intlala inyama kunye ukhakhayi ikepusi - nokuqina.

izinto nomsi- siqulathe ezininzi ushiye bone ezingcakacileyo wayalela ngokungqinelana ne ukuhamba kwezinto kule ithambo. Loo isakhiwo kwenza kube lula ukufezekisa amandla nangakumbi amathambo. Basemngciphekweni ukuba waphule ukuzivula.

Xa kungqameko ithambo intlala, apho kuza kube izakhi zingene kwalapho.

Le ukuqanda azele lomongo wethambo nomsi-, onoxanduva imveliso legazi elibomvu. Esi sikimu bone cancellous kuvumela ukwenza imisebenzi emininzi kwaye ebalulekileyo.

uhlobo

Ubume skeleton abantu ithambo nomsi- unokuzuza oluninzi. Ngenxa yoko, izazinzulu ziye zachongwa iqela esiXhoseni.

Ukwahlula bone caba womthamo. Planar benza ikepusi yaba lukakayi, kwisisu zangasese. Oku kubandakanya ngamaphiko. Womthamo lizisa iimbambo phalanges. Amalungu omqolo kubhekiselwa ukuba uhlobo njengoko engumxube, ngenxa yokuba umzimba ubunjwe umthamo bone cortical, kunye nenkqubo - flat.

Yi wesiko ubungakanani ukwahlula amathambo ubude nobufutshane nomsi-. Enye ezinemiphetho elide ziyaqwalaselwa. Kwakucingwa ukuba ezimfutshane amathambo phalanges izandla neenyawo.

Ithambo ezizodwa zingabizwa litha. It encamathele emzimbeni kuphela kusetyenziswa kwizicwili, lo gama uninzi amathambo enxulumene ukhule.

Imisebenzi wethambo nomsi-

Umsebenzi wokuqala kunye engundoqo leyo yenzelwa ithambo nomsi- - izalathiso. Bona ukudala amathambo olusisiseko ngamathambo abantu. Amalungu omqolo ngendlela lomqolo leyo exhasa umzimba uphela endaweni nkqo. Amathambo unyawo ugcina yonke ubunzima bomzimba.

Umsebenzi wesibini - zokhuselo. bone cancellous Human kunye nokudala umngxuma engqongwe, ukukhusela imixholo evela umonakalo yangaphandle. Le cap ukhakhayi, iimbambo kunye namathambo zangasese.

umsebenzi leZithuthi ihlala amathambo iinzwane nezandla phalanges yenziwe.

Kwimeko zokugxojwa yokucolwa bone libe ethe-ethe kakhulu yaye yanyamezela yahlala ithuba elide kakhulu. Kuzo zombini ezi meko, oko kuyingozi umsebenzi ophilileyo.

ukuzaliswa lwangaphakathi ithambo - nomongo - idlala indima enkulu ekubunjweni egazini.

Intsingiselo wamathambo

Emzimbeni womntu umzobo ithambo cancellous kuthetha ubukho isisinyanzelo kuwo kuyo abomvu umongo wethambo. Kubaluleke kakhulu ukuba ubomi into ekhoyo nkqu emathanjeni elide, kodwa amanani amancinci.

Ebuntwaneni, amathambo nomsi- kunye cortical zizaliswa ngokulinganayo iziyobisi, kodwa iminyaka tubular kwisisu ebegqwese ezaliswe ngamanqatha wamathambo ebengezelayo.

Eyona Umsebenzi wamathambo - le Yindibanisela iiseli ezibomvu zegazi. Yinto eyaziwayo ukuba ezi seli azinazo nuclei kwaye ayikwazi ngokwabo ukwabelana. Xa cancellous ukuba zivuthwe kwaye ngenisa egazini ngexesha nethe ithambo.

Kakuhle iziphumo lomongo wethambo kuzo izifo ezifana kwegazi kunye nomculo nomhlaza wegazi. Amaxesha amaninzi, iyeza le nto ngempumelelo, kwaye ukubhenela ebomvu lomongo abohlukeneyo.

Le nto-ethe kakhulu sesichengeni kwemitha. Ngoko ke, uninzi kuyo aziindidi nje ezahlukeneyo somhlaza wegazi. Le ndawo inye isetyenziswa ukufakelwa, xa ufuna ukubulala iiseli ezisulelweyo zivela lomongo wethambo.

umonakalo kunokwenzeka

Xa uhlobo amathambo cancellous liyayivumela ukuba nzima kakhulu ukuba umonakalo. Kodwa kukho iimeko apho isidima ithambo yaphukile.

Ukophuka ucinezelo luphawulwa ngokuveza ithambo ngenxa impembelelo kuyo. Olu hlobo umonakalo ezithandwa kakhulu amathambo. Ndenzakale kuba ngexesha kwendiza ongaphumelelanga ngeenyawo okanye ekungqulekeni. Ngengozi ngokwaphulwa ekubeni vertebra ayisekho ukukhusela umnqonqo, nto leyo inokukhokelela umonakalo.

Ekubeni inkoliso amathambo elide abe imilo kujikwa imfunxa-like, ukuze ivale ngethuba logwayimbo enogonyamelo nxamnye izinto nzima. zokulimala zikhuselekile kakhulu. Nokuzisa kwangethuba iintanda zokhathalelo lwempilo aphilise ngokukhawuleza.

Ngaba nomsi- amathambo kunye ikhefu. Kwezinye iimeko, le hlobo ngokuzenzakalisa phantse ingeyongozi. Ukuba akukho icala, bakhawuleza wachacha. Ingozi abo amathambo, nto leyo ke babhaca namanxeba amalungu abalulekileyo. Kwimeko enjalo, ezinjengokwaphuka nabungozi kakhulu uba unobangela yokukhubazeka kunye nokufa.

Amathambo kunye notshintsho ezinxulumene-yobudala

Njengazo zonke ezinye imibutho ithambo cancellous abantu ekucaca ukuba utshintsho ezinxulumene-ubudala. Xa ukuzalwa ithambo elizayo okanye hayi kuvuthwa okanye hayi ukusekwa intlala kunye zomzimba nokuqina.

Ndithanda ukuba "yome" Ukutyhubela iminyaka, amathambo. Oku kuthetha ukuba ukwakhiwa kwawo isixa kwezinto eziphilayo iba ngaphantsi, ngoxa izinto kwizimbiwa ukuba indawo. Amathambo zaqina elide kakulu umonakalo.

Inani lomongo wethambo chu kunciphisa. Ngoko ke, abantu abadala ezithandwa ngokwanele.
