Ukuhamba, Ukuzinza nokuQondiswa kweQumrhu
I-interspinales kunye ne-intertransversarii ziyinxalenye yecandelo elincinci lomsila. Nangona ezi zihlunu zincinci, zidlala indima kwezinye zezinto ezisemqoka zomgudu. I-interspinales kunye ne-intertransversarii bancedisa ngenkxaso yesikhala, ukuqonda ngesimo sakho somthunzi kunye nokubaluleka konke (kunye nakwezinye iziganeko zonyango) ukunyuswa kokubuyiswa kwangaphambili.
Ii-Interspinales kunye ne-Intertransversarii - IiNgcaciso zeSayithi
Uninzi lwamahlunu lunamathela kwaye luhambisa amathambo. Njengoko kunjalo nge-interspinales kunye ne-intertransversarii, ngezinye izihlunu igalelo ekuzinzeni ngokuzinzileyo, ngokunjalo. (Siza kuthetha ngale nto ngomzuzu.)
Umphumo womsebenzi womsizi osebenzayo emathanjeni apho baxhomekeke khona kuxhomekeka ngokukodwa kwindawo yabo kwindawo. Kule meko, i-vertebra nganye kwikholam yomgca iqulethwe ngumzimba (imizimba ibanjwe phezulu phezu kolunye umgca ukuze wenze yonke ikholwana yomgcini) kunye neendandatho zebony. Indandatho yebony ibambelela emzimbeni. Kulo mvenge webony yinkalo yeemeko ezikhulayo, ezibizwa ngokuba yiinkqubo. I-interspinales kunye ne-intertransversarii banamathela kwiinkqubo. Njengoko amagama aphakamisa, i-interspinales muscle ifakela kwinkqubo ye-spinous kwaye i-intertransversarii ifakela kwinkqubo ejikelezayo.
Intertransversarii
I-intertransversarii zincinci zengxube zeehlunu ezifakela inkqubo enye ehambayo kwinqanaba elilandelayo elihambelana nomgca wesihlwele.
Nangona izikhundla zabo kwiinkqubo ezithintekayo zingabenza ukuba bathathe inxaxheba ngaphakathi ekuguquleni nasekuhambeni ukunyakaza, iingcali aziqinisekanga ukuba ezi zihlunu ziyakwazi ukuvelisa umlinganiselo wamandla afanelekileyo ukwenzela ukwenza njalo. Kunoko, iingcali zikholelwa ukuba ukuphambana kwe-intertransversarii kunokunceda kunceda ukuzinzisa umlenze.
Kwakhona, entanyeni, (ebizwa ngokuthi "umgudu womlomo wesibeletho") i-intertransversarii iqulethe inani eliphezulu lamatholampilo enesibindi esenza ukuba uqaphele intshukumo yomlenze. Ngale ndlela, zinokukunceda ukuba uqaphele intshukumo yentamo yakho kwaye zichaphazela intshukumo yemisipha eseduze ngokunika ingxelo.
I-intertransversarii idibanisa zombini phambili nangemva kweenkqubo ezijikelezayo kwicala ngalinye lomgudu. Badibanisa nenkqubo ejikelezayo ye-vertebra ngasentla nangezantsi. Iimbini ze-intertransversarii ziyanda ukusuka kwi-vertebrae yentamo yokuqala (eyaziwa nangokuthi "i-atlas") kwi-vertebra yokuqala ye-thoracic kwaye kwakhona ukusuka kwi-vertebra ye-thoracic ukuya kwi-vertibra yesihlanu ye-lumbar.
Xa bobabini be-intertransversarii benza ngokubambisana, bayandisa kwaye baxhomekeke emthonjeni wakho. (Cinga ngokunyusa ukunyakaza njengemva yokubuya.) Xa kuphela izivumelwano zesikhumbuzo esisisigxina se-intertransversarii sinegalelo ekuhambeni kwecala. I-intertransversarii isebenza ne-interspinales, i-rotators, kunye ne-multifidus ukuvelisa le ntshukumo. Zonke zingezantsi kwinqanaba elincinci lemisipha yangaphakathi.
Interspinales
Njenge-intertransversarii, i-interspinales iifolthi ezimfutshane zemihlathi. Kodwa esikhundleni sokubambisana kwiinkqubo ezithintekayo ze-vertebrae, i-interspinales ikhona ngapha nangapha kwegermament interspinous.
Ngoko phi (kwaye yintoni) i-ligers interspinous? Ingumlenze wokudibanisa ohamba ngokuzenzekelayo kunye neengcebiso zeenkqubo ze-spinous. Iinkqubo zogxobhozo zifumaneka kwinqanaba leendandatho zebhontebrae. (Khumbula ukuba la mabhonkco ayamathisela kwiimpawu ze-vertebral ngasemva, kwaye ngeendlela iinkqubo zinika uxhumano phakathi kwamathambo omgulane kunye neendawo zokuncedisa izihlunu.)
I-interspinali \ es ifumaneka ngapha nangapha kwegermament interspinous. Ihamba ngokujikeleza kwintlambo ivela kwi-vertebra yesibili yomlomo wesibeleko (ekwaziwa nangokuthi i-axis) kwaye iyancipha ukuya kwi-vertebra yokuqala ye-1st okanye yesi-2, kwakhona kwakhona phakathi kwe-12 ye-thoracic okanye i-vertebra yesi-1 yesiqhelo ukuya kwi-sacrum.
Njenga-intertransversarii, i-interspinales muscle idlala indima ebalulekileyo ekuqiniseni umgogodla. Kodwa ngokungafani ne-intertransversarii, i-interspinali es muscle inceda ukuzinzisa umlenze ngelixa lihamba (eyaziwa ngokuba luzinzile.)
Kanye kunye nezinye izihlunu ezibandakanya ubuncwane obunzulu bezitho zangasemva zangaphakathi, i-interspinales nayo ithatha inxaxheba kwimigudu yokwehliswa nokubuyiswa kwangaphambili.
