Mienzaniso yeMibvunzo Kukurukura nezveMapfupa eMunhu seChishandiso cheKufamba
Mapfupa emunhu ndiwo mapuranga emukati memuviri, ane mapfupa nemapfundo anoshanda sekufamba-famba kusingafambi. Mapfupa haangopi muviri chimiro chete asiwo anodzivirira nhengo dzinokosha, anochengeta zvicherwa, uye anoita kuti kufamba kuenderere mberi kuburikidza nekushanda pamwe chete kwetsandanyama. Muchinyorwa chino, tichakurukura mienzaniso yakati wandei yematambudziko ane chekuita nemusoro uyu kuti tinzwisise zviri nani mashandiro, chimiro, uye matambudziko ane chekuita nemapfupa emunhu.
Nhanganyaya kuMapfupa Emunhu
Mapfupa emunhu ane mapfupa angangoita 206 muvanhu vakuru, akakamurwa kuita zvikamu zviviri zvikuru: mapfupa emusana nemapfupa emusana. Mapfupa emusana anosanganisira dehenya, musana, mbabvu, uye sternum. Mapfupa emusana anosanganisira mapfupa emakumbo, akadai semaoko nemakumbo, pamwe nechiuno nemafudzi.
Mibvunzo Yekukurukurirana
Heano mimwe mienzaniso yemibvunzo nehurukuro dzavo maererano nemapfupa evanhu senzira yekufamba:
Mubvunzo 1: Basa reMapfupa
Mubvunzo: Doma uye tsanangura mabasa matatu makuru emapfupa emunhu muhurongwa hwemapfupa nemapfupa.
Kukurukurirana:
1. Kutsigira Muviri: Mapfupa anopa chimiro chinotsigira muviri uye chinoupa chimiro. Pasina mapfupa, muviri wemunhu ungadai usina chimiro chakagadzikana.
2. Kudzivirira Nhengo Dzinokosha: Mapfupa emapfupa anoita basa guru mukudzivirira nhengo dzinokosha. Semuenzaniso, dehenya rinodzivirira uropi, uye mbabvu dzinodzivirira mwoyo nemapapu.
3. Inopa Nzvimbo Yekubatana Kwetsandanyama: Mapfupa anoshanda senzvimbo yekubatanidza tsandanyama dzetsandanyama, izvo zvinoita kuti dzifambe. Kana tsandanyama dzakabatana, dzinodhonza mapfupa, zvichiita kuti afambe.
Mubvunzo 2: Kuumbwa kweMapfupa
Mubvunzo: Ndezvipi zvikamu zvikuru zvepfupa uye chimwe nechimwe chinoshanda sei?
Kukurukurirana:
Mapfupa anonyanya kuumbwa ne:
– Bone Matrix: Yakagadzirwa ne collagen nemaminerari, kunyanya calcium ne phosphate. Matrix iyi inopa mapfupa simba nekuoma kwawo.
– Masero Emapfupa: Kune mhando nhatu huru: maosteoblast (vanovaka mapfupa), maosteocytes (vanochengetedza mapfupa), uye maosteoclasts (zvinoparadza mapfupa zvekugadzirisa nekugadzirisa).
– Bone Marrow: Iri mukati memapfupa, ine marrow matsvuku anogadzira masero eropa uye yellow marrow inochengeta mafuta.
Mubvunzo 3: Mhando dzeMajoini
Mubvunzo: Tsanangura mhando nhatu dzemajoini zvichibva pakufamba kwadzinobvumira uye ipa mienzaniso.
Kukurukurirana:
1. Hinge Joint: Inobvumira kufamba kwenzira imwe chete, sehinge yemusuwo. Mienzaniso inosanganisira gokora nemabvi.
2. Ball-and-Socket Joint: Inobvumira kufamba kwakasununguka kumativi ese. Semuenzaniso, majoini epafudzi nepahudyu.
3. Pivot Joint: Inobvumira kufamba-famba. Muenzaniso ijoini riri pakati pemapfupa emutsipa rinobvumira musoro kutenderera.
Mubvunzo 4: Matambudziko eMapfupa
Mubvunzo: Dudza uye tsanangura zvirwere zviviri zvemapfupa evanhu zvinowanzoitika.
Kukurukurirana:
1. Osteoporosis: Chirwere umo mapfupa anotyoka uye anotyoka nyore nyore nekuda kwekudzikira kwehuremu hwemapfupa. Izvi zvinowanzoitika nekuda kwekuchinja kwemahormone kana kushomeka kwecalcium nevhitamini D.
2. Arthritis: Kuzvimba kwemajoini kunokonzera kurwadziwa nekuomarara. Rudzi rwakajairika iosteoarthritis, iyo inokonzerwa nekusakara kwekatsi.
Mubvunzo 5: Maitiro Ekuporesa Mapfupa
Mubvunzo: Pfupa rakatyoka rinoporesa sei?
Kukurukurirana:
Kuporeswa kwemapfupa akatyoka kunosanganisira matanho akati wandei:
1. Kuumbwa kweHematoma: Mushure mekunge pfupa ratyoka, ropa rinomhanyira kunzvimbo yacho richigadzira hematoma zvichimisa kubuda kweropa.
2. Kuumbwa kweMakumbo Akapfava: Masero anoumba mapfupa (osteoblasts) anotanga kuumba fibrocartilage callus mukati memazuva mashoma kuti agadzirise kutyoka kwemapfupa.
3. Kuumbwa kweHard Callus: Fibrocartilage callus inotsiviwa zvishoma nezvishoma nemapfupa matsva, akaomarara kuburikidza nekuumbwa kwemapfupa.
4. Kugadziriswazve Kwemapfupa: Maitiro aya anotora nguva yakareba uye anosanganisira kuparadzwa kwakanyanya kwemapfupa nemaosteoclast uye kuumbwa kwemapfupa matsva nemaosteoblasts kusvika chimiro chemapfupa akatyoka chadzoka pakare.
Mhedziso
Mapfupa emunhu anoita basa guru mukuchengetedza hutano hwemuviri nekushanda zvakanaka. Nekunzwisisa chimiro, mashandiro, uye matambudziko angangoitika ehurongwa hwemapfupa, vanhu vanogona kutora matanho ekuchengetedza mapfupa nemapfundo ane hutano. Kunzwisisa izvi hakungokoshi chete mudzidzo asiwo kwakakosha pakusimudzira hutano huri nani. Munguva yekudzidza, matambudziko ekudzidzira akaita seaya ataurwa pamusoro apa anogona kubatsira kusimbisa kunzwisisa nekuchengetedza pfungwa pamusoro pehunhu hwemapfupa emunhu uye mashandiro awo.
