Le piece ngesandla: nokwakheka

nomlenze Upper indoda wadlala indima ebalulekileyo ukuyilwa yendaleko yakhe ibe uhlobo. Kweli nqaku siza kuqwalasela yinxalenye yoluntu kunye nezilwanyana izandla, ingakumbi isakhiwo kunye nokusebenza.

Isicwangciso jikelele isakhiwo nemilenze

Isiphelo eliphezulu lenziwa iinxalenye ezimbini. Eyokuqala ithi ibhanti equka clavicle kunye scapula. amathambo kwamalungu omzimba simahla - ingxenye yesibini iqhotyoshelwe kubo. Le ibandakanya omnye unpaired ihumerus. Yena slidably eqhagamshelwe zengalo ulnar kunye ziqu. Ezi ndima zilandelayo esandleni - le ibrashi. Ziqulethe amathambo carpal, metacarpal kunye phalanges.

Inxalenye engentla ingalo

Isakhiwo eli sebe siquka uhamba clavicle kunye scapula. La mathambo alo mlenze umbhinqo eliphezulu ukunika uxhulumaniso bhetyebhetye le skeleton buti nengalo free. Clavicle kwelinye icala liqhagamshelene breastbone caba kwelinye - kunye vane. Le ithambo iye eziliqela egosogoso kwaye uvalo kakuhle. osemqoka yayo ezisebenzayo kwi somzimba indawo kwegxalaba kumgama ukusuka esifubeni. Oku kwandisa kakhulu ke uluhlu isindululo imilenze eliphezulu.

Inxalenye esezantsi ingalo

Bone ezisekupheleni free skeletal movably adityaniswe ukwenza amalungu ezininzi: sternoclavicular, igxalaba, ingqiniba, radiocarpal. Zonke ezi zakhiwo isicwangciso esinye zokwakha. Kuyo nayiphi na intloko odibeneyo enye inxalenye lithambo nzulu enye. Ukuba ubuso ezingamadlelane abanazo zochuku sinxilisayo, zabo kugubungela hyaline intlala. isakhiwo ngasinye ezinjalo kwi philisi joint, ukuba ezithi nemisipha kunye nemisipha eziqhotyoshelweyo.

Ezinye iindawo isandla abe neempawu zabo. Umzekelo, nasesithupheni eliphikisa nakubo bonke abanye. Oku kuhambisana ubuchule bomntu ukusebenza ngabom.

Ubume izandla zabo bonke izilwanyana uhlobo olufanayo usinga. It iqulathe amaqela amathathu: emagxeni, inyuke iye nesandla. ukuba iimpawu zabo morphological neeyantlukwano enxulumene ezihlala izilwanyana. Ngoko ke, iintaka ngenxa yokuba ubuchule babo ukubhabha imilenze ephezulu sishintshe sibe ngamaphiko. Abamenzelayo shrews bafumane ukutya kwabo, ngokwenza enambuzelayo emhlabeni. Ngako oko ke, kufuneka olunzulu nemilenze ukumba. Abameli komyalelo amalulwane ezanyisayo naphaya endisabela esebenzayo ngenxa yobukho ezibayeni ulusu kunye neminwe evuthelweyo. ayabulala igama labo ngenxa yobukho kwingxelo zokuzikhusela horny kwi amalungu abo omzimba.

Indlela leli imilenze eliphezulu

Zonke iindawo abantu kunye nezilwanyana izandla ukuhambisa Bulelani kwizihlunu. Bona apha ithambo kunye nemisipha. Muscle, okubangela intshukumo ngokwamathambo alo, zidibene bangamaqela amabini. I nomlenze lokuqala uzimisele. Hi xikombiso, le izo-, okanye izo- ebangela ingalo umzimba. Extensors ukwenza imisebenzi nguqu. Abantu, lo msebenzi wenziwa le esineendidi. Deltoid omele kumacala angafaniyo. okuzenzela layo phezu komhlaba phambi zengalo, nengalo uzimisele. Kwaye abo ibekwe kwi ngasemva - phezu koko.

Isikhumba izandla iintlobo ezahlukeneyo receptor. Oku Iziseko ezikhethekileyo enovakalelo ukuqhagamshela umzimba kunye nokusingqongileyo. Bayakwazi ukuba akuguquki iintlobo ezahlukeneyo ze-luvo azilawule imiphumo. Ngenxa yoko, ulwazi unikelwa kwimimandla zesixhoboezifanelekileyo uthinte ebuchotsheni. iindlela Conductive kule meko ke luvo. Xa ingqondo, ulwazi kuyahlaziywa kwaye kwicala reverse inikezelwa umzimba ukusebenza. iintlobo ezininzi receptors ibekwe esikhumbeni izandla. Mechanical ukuqonda wegazi kwebala. Ingqele kunye lifudumeleyo umzimba ebona nge thermoreceptors. Kodwa inkoliso lonke ulusu izandla neminwe uvakalelo kwimbono intlungu. Bona bakha nociceptors.

imilenze Upper ngenxa awohluke ngesakhiwo inemisebenzi ezininzi ezibalulekileyo. Yeyona ukukwazi ukubhabha, ukuveliswa kokutya, ukwakha indawo yokufihla intloko. Ezona mpawu ephambili na esandleni umntu owenza umsebenzi wakhe kwaye sisiseko utshintsho ezininzi yendaleko.
