Mawu Oyamba: Kumvetsetsa Anatomy ya Ng'ombe
Ng'ombe ndi nyama zoweta zomwe zimagwiritsidwa ntchito kwambiri pazaulimi chifukwa cha nyama, mkaka, ndi zikopa. Kumvetsa mmene ng’ombe imakhalira n’kofunika kwambiri kwa alimi, akatswiri a zinyama, ndi asayansi a zinyama kuti atsimikizire kuti nyamazi zikukhala bwino komanso zobereka. Chomangira cha ng'ombe ndi chimodzi mwa zinthu zofunika kwambiri pa mwendo wakumbuyo wa ng'ombe, zomwe zimakhala ndi udindo woyendetsa mwendo komanso kuthandizira kulemera kwa nyama.
The Stifle Joint: Tanthauzo ndi Ntchito
Chomangira cholumikizira ndi cholumikizira cha hinge chovuta kwambiri chomwe chimalumikiza femur (ntchafu) ndi tibia (fupa la shin) lakumbuyo kwa ng'ombe. Ndizofanana ndi bondo la munthu ndipo limayang'anira kutambasula ndi kupindika kwa mwendo wakumbuyo, kulola ng'ombe kuyima, kuyenda, ndi kuthamanga. Kuphatikizikako kumakhudzidwanso ndi kugwedezeka kwa mantha, chifukwa kumatulutsa kulemera kwa nyama kuchokera ku femur kupita ku tibia, ndipo kumathandiza kuti azikhala okhazikika komanso okhazikika panthawi yoyenda.
Mafupa a Mphatso ya Ng'ombe
Mgwirizano wa ng'ombe umapangidwa ndi mafupa atatu: femur, tibia, ndi patella. Mafupawa amagwira ntchito limodzi kuti apange mgwirizano wokhazikika womwe ungapirire kulemera ndi mphamvu ya kayendetsedwe ka nyama.
Femur: Fupa Lalikulu Kwambiri mu Stifle
Femur ndi fupa lalikulu kwambiri la stifle joint ndipo limayang'anira kulemera kwa nyama. Ndi fupa lalitali lomwe limachokera ku chiuno mpaka ku bondo ndipo limagwirizanitsidwa ndi tibia ndi mitsempha ndi minofu.
Tibia: Fupa Lachiwiri Lalikulu Kwambiri mu Stifle
Tibia ndi fupa lachiwiri lalikulu kwambiri pamagulu osakanikirana ndipo limapanga gawo lapansi la mgwirizano. Ndi fupa wandiweyani lomwe limathandizira kulemera kwa nyama ndikulumikizana ndi femur ndi patella.
The Patella: Kneecap of the Stifle
Patella ndi fupa laling'ono, lathyathyathya lomwe limakhala kutsogolo kwa femur ndi tibia ndipo limakhala ngati pulley kwa gulu la minofu ya quadriceps. Zimathandizira kukhazikika kwa mgwirizano ndikuletsa kusuntha panthawi yoyenda.
Minofu ndi Mitsempha ya Stifle Joint
Mgwirizano wokhazikika umathandizidwa ndi minofu yambiri ndi mitsempha yomwe imapereka mphamvu ndi kukhazikika kwa mgwirizano.
Gulu la Minofu ya Quadriceps: Main Movers of the Stifle
Gulu la minofu ya quadriceps ndilomwe limayendetsa cholumikizira cholumikizira ndipo limayang'anira kukulitsa mwendo. Amapangidwa ndi minofu inayi: rectus femoris, vastus intermedius, vastus lateralis, ndi vastus medialis.
Mitsempha ya Collateral: Stabilizers of the Stifle
Mitsempha yachitsulo ndi magulu awiri amphamvu a fibrous omwe amapereka kukhazikika kwapakati pa olowa. Amagwirizanitsa femur ku tibia ndikuletsa mgwirizano kuti usasunthike mbali ndi mbali.
Menisci: Mapiritsi a Cushioning a Stifle
Ma menisci ndi zigawo ziwiri za cartilage zomwe zimakhala pakati pa femur ndi tibia ndipo zimakhala ngati mapepala. Amathandiza kugawa kulemera kwa nyama mofanana ndi kuchepetsa kukangana kwa mgwirizano.
Kupereka Magazi ndi Kusungidwa kwa Mgwirizano wa Stifle
Cholumikizira cholumikizira chimalandira magazi kuchokera ku mitsempha yambiri, kuphatikiza mitsempha yachikazi, genicular, ndi popliteal. Cholowacho chimakhalanso chosatetezedwa ndi mitsempha yambiri, kuphatikizapo mitsempha ya femoral ndi sciatic.
Kufunika Kwachipatala kwa Kuvulala Pamagulu Ophatikizana pa Ng'ombe
Kuvulala kwamagulu ophatikizika kumakhala kofala kwa ng'ombe ndipo kumatha kuchitika chifukwa cha kuvulala, kugwiritsa ntchito mopitirira muyeso, kapena kusintha kosinthika. Kuvulala kumeneku kungayambitse kupunduka, kuchepa kwa zokolola, ndi kupweteka kwa nyama. Njira zochizira matenda ophatikizika a ng'ombe zimaphatikizapo kupuma, mankhwala oletsa kutupa, ndi opaleshoni, malingana ndi kuopsa kwa chovulalacho. Kuzindikira koyambirira ndi kuchiza kuvulala kwamagulu opunthwa ndikofunikira kuti chiweto chikhale bwino komanso kuti chikhale chogwira ntchito bwino.
