Imisipha yemilenze ephezulu yomntu: isakhiwo kunye nemisebenzi

Izitho ezingaphezulu zixhobo ezibalulekileyo. Ngenxa yobukho babo, abantu banako ukwenza izinto ezahlukeneyo kunye nezenzo.

Isatomy of the upper leg

Isakhiwo sesakhiwo siquka:

• Isikhumba.
• Imisipha.
• Isifuba samathambo.
• Imikhumbi yegazi.
• Iimpahla.

Le yimizimba yesigxina esiphezulu. Iingalo ezilungileyo nezisekhohlo ziyahlukana. Ubungakanani kunye nokuma kweebhulashi ziyahluka, umzekelo. Ingalo yesobunxele imfutshane kunelungelo, malunga nesiqingatha sesentimitha. Ifom leyo izitho ezingaphezulu zixhomekeke kumsebenzi, ubudala, ngesondo. Akukho nto ibaluleke kakhulu yimeko ebanzi yomzimba. Isakhiwo sesigxina esiphezulu sinqunywe yimisebenzi yaso. Kwakhona ngenxa yezinto ezikhethiweyo zesakhiwo sesisu. Imisebenzi yamagcekeni angaphezulu aphezulu kakhulu. Ngombulelo kwizenzo zabo, abantu banokubamba izinto, babhale, gesticulate njalo njalo. Emva koko, siya kuqwalasela ukuba izihlunu zamagcekeni angaphezulu.

Inatomy of musculature

Iifayili zihlulwe zibe zimbini iintlobo. Imisundu yebhande lehlombe ibhekisela kwiyokuqala, ukuya kweyesibini - ukuya kwinxalenye yamahhala. Ukwahlula kwenziwa ngokuxhomekeke kwimisebenzi eyenziwa kwaye indawo (ekupheleni kwinqaku letafile iya kufakwa). Imisipha yamagcekeni aphezulu kummandla webhanti yegxala lihlukaniswe libe yi-deltoid, i-supra- ne-subacute, ijikelezi ezincinane kunye ezinkulu, kunye neefayili ezixhasayo. Ibhinqa lehlombe liquka imisundu yesandla, ihlombe kunye neengcambu.

Imida ejikelezayo

Banobunzima obol. Uqala ukusuka ngasemva kwekhoneni eliphantsi kwi-scapula. Ezi zihlunu zamagcekeni aphezulu zijonge kwi-hillock encinci kwi-humerus (kwi-crest). I-calving yangemuva isondele kwimiqolo ebanzi. Imisipha ejikelezileyo yamagcekeni aphezulu, kunye nokuqhekeka, ukukhupha ihlombe, ukuyijika ngaphakathi. Ngenxa yoko, isandla sibuyela kwisiqu.

Iifayili zeDeltoid

Zinikezwa ngolu hlobo lwenxantathu. Ngaphantsi kwengxenyana engezantsi yale msimba yamagcekeni angaphezulu afunyanwa izikhwama zobuxoki. Iimbombo zimboza umxhelo wexhepha ngokupheleleyo kunye ne-musculature yamagxa endaweni. Umzimba we-deltoid uquka iindawo ezininzi eziguqula kwi-pepeid. Bahlukene ngokwemisebenzi. Umqolo uphakamisa ingalo, phambili phambili. Iifayibha ziqala ukusuka kwi-axis ye-scapula (ekupheleni kwe-lateral) kunye nenxalenye ye-clavicle. Isayithi yokulungiswa yi-deltoid tuberosity kwi-humerus. Imisipha ye-deltoid yamagcekeni angaphezulu ajika amahlombe abo ngaphandle ngaphandle kokuba athathe indawo engezantsi.

Iifayili ezincinane ezijikelezayo

Benza i-muscular round clock. Ingxenyana yangaphambili yayo ihlanganiswe neefayili ze-deltoid, umva - ngeenxa zonke ezinkulu. I-muscle iqala kwi-scapula, ngaphantsi kwee-fibra-shaba, apho iindawo zayo eziphezulu zihamba. Icandelo liqhotyoshelwe kwisayithi kwi-humerus ye-humerus kunye ne-capsule yombutho (kunye nendawo engezantsi). I-muscle ijika ihlombe ngaphandle, idonsa kwaye ibuyise i-capsule yombutho.

Filament fibers

Bakha imisipha emithathu. Itholakala kwi-fossa yangaphantsi ngaphantsi kwecandelo le-trapezoidal. Isayithi yokulungiswa yimva ye-capsule yendibano yegxala kunye ne-pad kwi-tubercle enkulu yethambo. I-muscle iqala phezu kwe-fossa. Xa iifayili zivumelwano, iphakama liphakama kwaye i-capsule yombutho udibaniswa, ovimba ukuthintela.

I-sub-fibers

Bakha i-muscular flat muscle. IiFibers zifumaneka kwi-fossa ye-subscapular. Kwiziko lokuqhayisa, kukho isikhwama sethenda. I-muscle iqala kwi-fossa ye-subscapular, kwaye iphela-kwi-tubercle encinci kwi-humerus nakwinkalo yangaphambili ye-capsule yombutho. Ngokunciphisa iifayili, igalelo lijikeleza ngaphakathi.

Iimbombo ze-Subacute

Bakha i-flat squangular muscle. Icandelo le-subacute likhoyo. Ukuqala kwemibhobho ifumaneka eludongeni nasemva kwe-scapula. Ixhomekeke kwi-capsule ekuhlanganyeleni kwegxala kunye nakummandla ophakathi kwi-tuberosity enkulu yethambo, phantsi kwayo ikhona isikhwama esingenakunyaka. Ukusika, i-muscle ijika ihlombe ngaphandle, ikuvumela ukuba uhoxise isandla esiphakanyisiweyo, ukhuphe i-capsule yombutho.

Imisundu yeli gxalaba

Ikwahlula ngamaqela amabini. I-front yenza i-bellxion, kwaye i-back isenza i-bell of the shoulder kunye ne-forearm. Iqela lokuqala libandakanya izihlunu ezinama-double-headed, brachial and bum-like. Inxalenye yesibini iqukethe imisipha ye- triceps kunye neelbow of the upper feet of man.

Iifayili eziphezu kabini

Bakha i-muscle edibeneyo ejikelezayo. Ekubunjweni kwayo kukho iintloko ezimbini: elifutshane, ethwele isandla, kunye nexesha elide lokuvelisa. Olu lugqitha luqala kwi-tubercle ephawulekayo ye-scapula. Intloko e mfutshane isuka kwinkqubo ye-coracoid. Endaweni yoxhumano lwabo, isisu sisenziwa. Iqhotyoshelwe kwi-tubercle kwi-radius. Kulo lathiso lwangaphakathi kukho iintlobo ezininzi. Benza inkqubo ye-lamellar - i-aponeurosis. Ukuqhubela phambili kudlulela kwi-faserus fascia. Imisebenzi ye-biceps yintshintsho ye-forearm kunye nekhenkco ye-forearm kwi-elbow.

Biliac fibers

Benza i-muscle flat. Ihlanganiswe ngentloko emfutshane yecandelo eliyihloko ezimbini. Imisipha ye-Biliary yamagcekeni angaphezulu omntu aqala kwiphepha lesigxina. IiFibers ziqhotyoshelweyo ngaphantsi kwinqanaba lenxalenye ye-humerus. Ngenxa yokunciphisa kwabo, iphakamileyo liphakama, izandla zikhokelwa kumgca wokulinganisa.

Iimbumba zehlombe

Bakha i-muscle e-shaped shaped. Isiqalo sawo sibheke phambili nangaphandle. Ukulungiswa kwenziwe kwintambo ye-tubercle kunye ne-elbow capsule. IiFibers ziphela ngokupheleleyo kwicandelo elincinci elincinci (kwicala langaphambili) phantsi kwe-biceps muscle.

Icandelo le-ulnar

Esi sihlunu sinesimo sepramramidal. Isiqalo sawo siyi-epicondyle ye-lateral ye-bone shoulder. IiFibers ziqhotyoshelwe kumqolo we- bone womzimba kunye nenkqubo ephambili. Ukusika, i-muscle iqhubela phambili. Ukwadibanisa ukudonsa i-capsule kwi-jointbow.

Iintambo ezineentloko

Bakha i-muscle ende. Iqukethe iintloko ezi-3: eziphakathi, ezisezantsi kunye nezide. Isiqalo saloo mva siyi-tubercle engummiselo. Inhloko yentloko ihamba kwi-posterolateral ingxenye yecala lesigxina, umlambo ovela kwindawo engaphezulu. Izinto zifakwe kwisisu esiswini. Emva koko sidlulela kwi-tendon. Isinamathiselo esisisu sisenziwa kwinkqubo ye-capsule kunye neelbow. Xa iifayili zivumelwano, i-forearm ingasebenzi, ingalo iyahluthwa kwaye ihlombe ifakwe kwi-trunk. I-muscle itholakala kwi-elbow kuya kwisiqwenga.

Ukuqhelana neFibers

Bakha amaqela amabini emisipha: phambi nangemva. Kuzo nganye zikho iimbombo zobunzulu obunzulu kunye nobunzulu bomhlaba. Iyokugqibela kwiqela eliphambili liquka i-flex flexers (i-ulnar kunye ne-radial) kunye neminwe, inxalenye ye-humerus, i-pronator ejikelezayo. Isebe liquka izihlunu ezinde. Kwinqanaba elincinci kukho umprofeti wesikwere, i-flexors: ityhufu ende kunye nomunwe onzulu. Imisipha yangaphandle yeqela elingaphambili iquka i-elbow, iifutshane ezide kunye nexesha elide zokugqithisa izixhobo, isinwe kunye nomunwe omncinci. Kwinqanaba elincinci lisebe kukho umgcini-mgcini, izihlunu ezitshintshayo kwaye ziguqulwe isithupha (esifutshane kunye nexesha elide);

Iimpawu zesandla

Iimisipha zisebusweni. Ama-fibers ahlukaniswe ngamaqela amaninzi: aphakathi, aphakathi, asemgangathweni. Emuva komphezulu webhasibhi yimizimba efana neyodwa. Kwiqela elixhasayo, kukho iifayile ezilungisa ukunyakaza kwesithupha: ukuchasa, ukukhokelela, i-flexors kunye ne-retractors. Isebe eliphakathi liquka intloko emfutshane yesundu kunye nomnwe omncinci. Ezi zilandelayo ziquka iifomfri ezimfutshane, ezikhokelela kunye nezibuyiselayo. Kwinqanaba eliphakathi kukho izilwanyana ezinjengeembumba, izilwanyana kunye neengqungquthela zengxowankulu.

Itheyibhuli. Imisipha yamalungu angaphezulu

Siyathemba ukuba ulwazi olubonelelwe luya kunceda kuwe.
