Yintoni i-tendon? (I-tendon) Makhe sithethe ngale nto ngokulula!

Ngaba wakha wazibuza ukuba kwenzeka ntoni emzimbeni wakho xa ushukumisa ingalo okanye umlenze wakho, ubaleka, okanye utsiba? Singenza zonke ezi zinto kuba izihlunu namathambo emzimbeni wethu asebenza kunye. Ngoko ke, uyazi ukuba yintoni edibanisa ezi zihlunu namathambo? Yiloo nto siyibiza ngokuba yi-tendons . Siza kuthetha ngezi tendon namhlanje.

Yintoni kanye kanye i-tendon?

Ngamafutshane, i-tendon sisiqwenga sethishu esomeleleyo nesiguquguqukayo, njengentambo. Cinga ngayo, unezihlunu, kwaye ezo zihlunu zibanjwe ngokuqinileyo emathanjeni zezi tendon. Zifana nebhulorho phakathi kwezihlunu namathambo. Xa uphakamisa ingalo, xa ugoba ingalo, xa ugoba ingalo, ezi tendon ziyanceda kuyo yonke le nto.

Sinamawakawaka ala ma-tendon emizimbeni yethu, ukusuka entloko ukuya ezinzwaneni zethu. Usenokuba ukhe weva nge- "Achilles tendon." Leyo yi-tendon edibanisa izihlunu ezisezinyaweni zethu nethambo lesithende. Enyanisweni, yeyona tendon inkulu emizimbeni yethu.

Le misonto ayikrazuki lula, inamandla kakhulu. Nangona kunjalo, ayoluki njengebhanti yerabha. Oko kuthetha ukuba inokwenzakala lula ukuba yoluliwe kakhulu (ukutsalwa). Ukuba oko kuyenzeka, kuthatha ixesha ukuphola.

Kwenzeka ntoni ngokwenene nge-tendon?

Kulungile, ngoku makhe sijonge ukuba kwenzeka ntoni nge-tendon. Kwenzeka ntoni xa uqinisa ingqondo ('i-contract') isihlunu? Emva koko, i-tendon enamathele kuloo sihlunu itsala ithambo elihambelanayo. Kulapho ithambo lishukuma khona, oko kuthetha into efana nengalo okanye umlenze wakho uhamba.

Imisipha ifana "ne-levers" enceda ekushukumiseni amathambo xa izihlunu zifinyela kwaye ziphumla. Iqinile kunemisipha kwaye inamandla amakhulu. Umzekelo, eminye imisipha enyaweni yakho inokuxhasa ubunzima bomzimba wakho obuphindwe kasibhozo! Ayimangalisi loo nto?

Iphi i-tendon?

Njengoko bekutshiwo ngaphambili, imisipha ifumaneka kuyo yonke imizimba yethu. Umzekelo, imisipha idibanisa izihlunu namathambo kwiindawo ezifana nengqiniba yakho, iqatha, idolo, igxalaba, kunye nesandla. Oku kuthetha ukuba le misipha ikunceda ukuba ushukume phantse kuyo yonke indawo.

Zithini iindawo ze-tendon?

I-tendon ayilonto nje yentambo. Inesakhiwo esintsonkothileyo ngaphakathi. Makhe sijonge ukuba zeziphi ezo ndawo:

• I-Epitenon: Le yingqimba encinci yezicubu ezinxibelelanayo ezijikeleze i-tendon yonke, njenge-sheath encinci ebekwe phezu kwe-tendon.
• I-Paratenon: Le ifumaneka ngaphandle kwe-epitenon. Yithishu edibeneyo ekhululekileyo. Yile nto evumela i-tendon ukuba ijikeleze ngaphandle kokuchukumisa izicubu ezijikelezileyo.
• Iifayibha zeSharpey: Ezi luhlobo lwefayibha ye-collagen edibanisa i-tendon nethambo ngokuqinileyo.
• I-Endotenon:Le yilaphu elidibanisayo elijikeleze ii-fibre bundles eziphambili, ezesibini, kunye nezesithathu ngaphakathi kwe-tendon. Inceda ezo fiber bundles zityibilike ngaphakathi kwe-tendon ngaphandle kokukhuhlana.
• Isingxobo (Synovium): Eminye imisipha ezandleni nasezinyaweni zethu inesingxobo esijikelezileyo. Ifana nesigqubuthelo sokukhusela isingxobo. Ivelisa into yokuthambisa ebizwa ngokuba yi-synovial fluid . Le nto ivumela isingxobo ukuba sityibilike lula apho sidibana khona nezihlunu kunye nethambo. Nangona kunjalo, ayizizo zonke imisipha ezinale singxobo.

Zibukeka njani ii-tendon? Zenziwe ngantoni?

Iitendon zenziwe kakhulu yiproteni ebizwa ngokuba yi -'Collagen' . Le 'Collagen' yiproteni eqhelekileyo efumaneka kwiindawo ezininzi zomzimba wethu. Ukongeza, kukho imithambo yegazi kunye nemithambo-luvo ngaphakathi kwi-tendon.

Iifayibha zeCollagen ziguquguquka kakhulu, zinamandla, kwaye azinakonakala lula. Ulwakhiwo lwetendon lufana nentambo yefiber-optic okanye intambo. Iifayibha zecollagen ezincinci zihlelwe zibe ziibhanti. Olu lwakhiwo lwebhanti lwenza itendon ibe namandla ngakumbi.

Ezi ziqwenga zeefayibha ze-collagen kwi-tendon zahlulwe zibe ziinxalenye ezincinci:

• Ii-Subfascicles: Ezi zezona zincinci kakhulu.
• Iifascicles zesibini: Ezi zenziwa kukudibana kweefascicles ezininzi eziphambili.
• I-fascicles ephezulu: Ezininzi zezi fascicles zesibini ('iifascicles') ziyadibana ukuze zenze i-tendon yonke.

Imisipha idibana njani nezihlunu namathambo?

Kukho iindawo ezimbini eziphambili zokunxibelelana kwimisipha:

• I-Musculotendinous junction (MTJ): Kulapho i-tendon inamathela khona kwimisipha. Le yindawo ehlala yenzakala.
• I-Osteotendinous junction (OTJ): Kulapho i-tendon inamathela khona kwithambo.

Kukho ezo 'fibers ezi-Sharpey' endizikhankanyileyo ngaphambili, eziya nzulu ethanjeni zize zibambe i-tendon ngokuqinileyo. I-tendon engalweni okanye emlenzeni ngamanye amaxesha idlula kunxibelelwano olufana ne -'reflection pulley' olunceda ukuba zihlale zisendaweni yazo. Kwakhona, apho i-tendon inamathela khona emathanjeni, kukho iingxowa ezincinci, ezizaliswe lulwelo ezibizwa ngokuba yi -'tendon bursae' . Ezi zisebenza njengomqamelo we-tendon.

Zeziphi izifo kunye neengxaki ezinokuchaphazela imisipha?

Ekubeni imisipha idibanisa phantse yonke imisipha emzimbeni wethu, inokuchaphazeleka ziintlobo ngeentlobo zokwenzakala kunye neemeko, ingakumbi njengoko sikhula .Iingxaki zemisipha zinokwenzeka ngakumbi. Oku kungenxa yokuba njengoko sikhula, imisipha iba buthathaka, igazi layo liyancipha, kwaye umonakalo omncinci kwiifayibha zemisipha unokuqokelelana, nto leyo ewenza buthathaka imisipha.

Ezinye zezona meko zixhaphakileyo ezichaphazela imisipha zezi:

• I-Enthesopathy kunye ne-Enthesitis: Ezi ziimeko zokudumba ezenzeka apho i-tendon inamathela ethanjeni.
• Iintlungu: Oku kwenzeka xa imisipha yoluliwe kakhulu kwaye inxalenye yayo ikrazuka. Sele sithethe ngale nto ngaphambili.
• I-Tendinosis: Oku kukuncipha kancinci kancinci kwee-collagen fibers kwi-tendon. Oku kunokwenzeka ngaphandle kokudumba.
• I-Tendonitis: Oku kukudumba kwe-tendon. Oku kuthetha ukuba i-tendon iyadumba kwaye ibe buhlungu.
• I-Tenosynovitis: Eli ligama elithetha ukudumba kwe-tendon sheath (synovium) ekuthethwe ngayo ngaphambili.

Ndingayigcina njani imisipha yam iphilile?

Zininzi izinto onokuzenza ukuze uzikhusele kwizifo ezinxulumene nemisipha. Kungcono ukuzenza umkhwa ezi zinto:

• Ukulinganisela i-cardio, uqeqesho lokuqina, kunye nokuzilolonga ngokuguquguquka: Ukwenza imithambo eyahlukeneyo, endaweni yohlobo olunye lokuzilolonga, kunokunceda ukunciphisa uxinzelelo olungeyomfuneko kwimisipha yakho.
• Mamela umzimba wakho: Xa udiniwe okanye uxinezelekile, khululeka. Ngale ndlela, akuyi kuba lula ukwenzakala.
• Yeka ukuzilolonga ukuba uziva iintlungu: Ukuba uziva iintlungu ngexesha lomsebenzi, yeka ukuyenza, linda ithutyana, uze uzame kwakhona. Ukuba uziva iintlungu, yeka ukuyenza.
• Yolula emva kokuzilolonga: Kungcono ukolula emva kokuzilolonga xa izihlunu zakho zifudumele kwaye ziguquguquka. Ungaze wolule ude uve iintlungu. Oku kuya kunceda ukuthintela ukwenzakala kwemisipha.
• Zifudumeze ngaphambi kokuba uzilolonge: Ngaphambi kokuba uqale umthambo onzima, ukwenza eminye imisebenzi elula ye-aerobic okanye ukubaleka endaweni ethile kunokunyusa ukuhamba kwegazi kwaye kukhulule izihlunu zakho.
• Nxiba izihlangu zemidlalo ezifanelekileyo: Ukunxiba izihlangu ezifanelekileyo kumdlalo owudlalayo kwaye ezilingana kakuhle neenyawo zakho kuya kunceda ukugcina umzimba wakho ulungelelene (`ulungelelwano`).
• Cwangcisa iintsuku zokuphumla: Ukuthatha iintsuku zokuphumla phakathi kweentsuku zokuzilolonga kunokunceda ekunciphiseni uxinzelelo olugqithisileyo kwimisipha.

Okokugqibela, izinto ekufuneka uzikhumbule

Ii-Tendons, okanye oko sikubiza ngokuba yi-'sinews', ziyinxalenye ebaluleke kakhulu kwimisipha yethu ezidibanisa namathambo ethu. Nangona singacingi kakhulu ngazo kubomi bethu bemihla ngemihla, zibalulekile kwiintshukumo zomzimba wethu. Ngokugcina imisipha yakho iphilile, unokuzikhusela ekwenzakaleni okungeyomfuneko.

Kodwa khumbula, ukuba unentlungu engapheliyo naphi na emzimbeni wakho, okanye intlungu engapheliyo, ngokuqinisekileyo kuya kufuneka ubone ugqirha. Yena ke unokuxilonga ingxaki yemisipha yakho aze akunike unyango olufanelekileyo.

Ngoko ke, khathalela umzimba wakho kwaye uhlale usempilweni!
