Human skeleton tibia. Small futhi tibia

Yini abancane tibia? Likuphi ngamunye wabo? Kangakanani uxhumano yabo?

Eyokuqala (tibia) ithambo itholakala medially.

Isisindo umzimba idluliselwa endaweni nozime mpo (mechanical) lonke umlenze axis. Tibia ithambo exhunywe kwi-ethangeni ngokusebenzisa ngokuhlanganyela kwedolo. Lower esitho eksisi eqonde ngqo phezulu sidlula isikhungo we ngokuhlanganyela amadolo enkabeni joint iqakala. Tibia umlenze uzalela isisindo emzimbeni, okuholela omkhulu (uma ziqhathaniswa nezincane) ukujiya.

Ngezinye izikhathi kukhona ukuphambuka ohlangothini lateral noma medial, okuyinto luhambisana nomthwalo ushintsho igebe eliphakathi tibia futhi kunawo wonke. Lapho liphinyiselwe kakhulu ukuphambuka we waphawula "X-okwenyanga" noma ukuthi "O emise" uhlobo imilenze.

I epiphysis (onqenqemeni proximal) yakha ezimbili (ezilingene medial) condyle. Ekufakeni isinghonghoyilo, kuse ecaleni hip banayo slabovognutye platform ngokuhlanganyela ezisebenza umsebenzi yokuxhuma. Ukwehlukanisa evele articular we condyles Elevation wenziwa namasumpa ezimbili. Ukuphela front futhi bakhulise we kokuphakama ingenye imbobo encane. I evele of emalungeni ezizungezile onqenqemeni uqweqwe (trace lokunamathelisa ka egobolondweni lelunga). Ngaphambili kobuso ithambo esinzima iqhubu omkhulu - isayithi umsipha okunamathiselwe (njengoba ayefika emadolweni umsipha) quadriceps. ingxenye Posterolateral we condyle lateral kuhlanganisa a surface flat ezincane (okunamathiselwe indawo fibula bone head). Umzimba siqukethe phambi, ubuso ezilingene medial phakathi okuyinto zitholakala posterior, medial kanye evele lateral. Ngesikhathi esifanayo sharpest (phambili) ubuso kanye ebusweni medial ngokucacile kuthintwe ngesikhumba. Ohlangothini medial we ephansi ekupheleni distal (epiphysis) has inqubo eqinile (malleolus medial), ngemuva lapho inkatho uyisicaba. Ngo onqenqemeni lateral sokuphela distal inqanyulwa, lapho ijoyina ezincane futhi tibia. Eziguquliwe ngezinyawo Abut skeleton zivuliwe emaphethelweni phansi.

Eyesibili (amancane, zondile futhi eside, ne semikhawulweni uqweqwe) itholakala ku tibia tibia singatsheki. Inhloko proximal (engenhla) yakha epiphysis. Ngu roundish flat surface Ilunga kulapho eseduze engokoqobo tibial condyle ithambo. ikhanda Upper - protrusion elise kancane posteriorly futhi singatsheki kusukela kule ebusweni. Triquetrum umzimba shape kancane basonta yonkana eksisi longitudinal. I distal (engezansi) epiphysis is uqweqwe bese yakha lateral (bushelelezi kwamanzi ngokuhlanganyela) we iqakala.

Ngokuvamile abantu baphuka izinqulu we condyles (umonakalo intraarticular) we tibia.

Ngokuvamile kwenzeka emlenzeni aphansi owangaphakathi ukuphambuka noma phandle, noma ngesikhathi kuwa ngemilenze ngqo. Hlukanisa ukwa condyle zangaphakathi nezangaphandle. umonakalo naphakathi-articular kungase kuhambisane ukulimala apharathasi umsipha e kwedolo, meniscus, ukuphakama intercondylar, fibula bone head nokunye.

Ngokuvamile abantu baphuka izinqulu ahambisana ukwanda ngevolumu joint, nge esitho kancane insaliwe. A ukuphambuka phandle drumsticks (uma elimele condyle yangaphandle) noma ngaphakathi (uma elimele condyle yangaphakathi). Esikhathini condyles ubukhulu transverse kakhulu anda. Kukhona ukuntuleka ukunyakaza asebenzayo emalungeni, kuhlanganise ukungakwazi ukukhulisa ngezinyawo isimo waqonda. Lapho yokwenziwa ukunyakaza kukhona ubuhlungu obuhlabayo. Kwezinye izimo umonakalo kuhambisana umonakalo yangaphandle condyle fibular ithambo entanyeni noma ikhanda. Kungase kube waphawula ukulimala kwenzwa ukuthi kutholwa ukwephulwa ukuzwela kanye motor umsebenzi unyawo.
