Imisipha wemikhawulo engenhla yomuntu: lokuphatselene nesakhiwo nemsebenti

nemilenze Upper kukhona yithuluzi elibalulekile. Ngenxa yobukhona babo, abantu nethuba ukwenza ezihlukahlukene ukunyakaza nezenzo.

Anatomy of the emkhawulweni engenhla

Isakhiwo Ukwakheka yakhiwa:

• Isikhumba.
• Imisipha.
• Bone skeleton.
• imithambo yegazi.
• Amaqoqo.

Lena anatomy esitho elingenhla. Ilungelo futhi isandla sobunxele zihlukile komunye nomunye. emasayizi nabobunjwa labehlukene emabhulashini, isibonelo. Ngesandla sobunxele mufushane kuka ilungelo cishe isigamu isentimitha. Ifomu, ezithinta nemilenze engenhla, kuncike kulo mkhakha, iminyaka, ubulili. Okunye futhi okubaluleke ngokufanayo impilo jikelele. Isakhiwo esitho elingenhla kuchazwe izinhloso zayo. Libuye ngenxa izici of isakhiwo izicubu. Upper emkhawulweni umsebenzi ngempela ebanzi. Ngokusebenzisa izenzo zabo Abantu bangaziqonda izinto, ngokubhala, ukushukuma komzimba, nokunye. Ngokulandelako, cabangela kuyini imisipha wemikhawulo engenhla.

ezicutshini nokwakheka

Ukotini Wekhethelo zihlukaniswe izinhlobo ezimbili. Isigaba sokuqala sihlanganisa imisipha kwebhande ehlombe, kwesibili - mahhala ingxenye. Ukwahlukanisa Kwenziwa kuye ngezidingo zakho nendawo (ekupheleni etafuleni sihloko zizonikezwa). Imisipha wemikhawulo eliphezulu kwebhande ehlombe sehlukaniswe deltoid, supra- futhi infraspinatus, ezincane nezinkulu, nxazonke, futhi subscapularis fibre. Isakhiwo kwebhande ehlombe kuhlanganisa ezicutshini uhlangothi, ehlombe ibhodi lemisindo.

Elikhulu nxazonke fibre

Banesimiso ukuma side flat. Qala kusuka ezingemuva nekhona elingezansi ku ikhaba. Lezi imisipha nasemilenzeni engenhla asethe njó indunduma ezincane humerus (Crest). Engemuva Ihhotela adjoins kwezintambo zesivikelo sesifuba ezibanzi emuva. Teres kwemisipha emikhulu wemikhawulo elingenhla ngenkathi ekunciphiseni udonse kwehlombe layo, emnikela ngaphakathi. Ngenxa yalokho, isandla ebuyiselwa umzimba.

le micu deltoid

Basuke ethulwa ngesimo calantsatfu. Ngaphansi engxenyeni engezansi imisipha esitho elingenhla zitholakala izikhwama subdeltoid. Ukotini Wekhethelo camera joint ehlombe ngokuphelele futhi imisipha ehlombe endaweni. I deltoid kuhlanganisa izinsika ezinkulu ukuthi izingxenye phezulu. Bahlukene ngokuvumelana imisebenzi. Engemuva wadonsa ngesandla sakhe emuva, phambili - phambili. Qala Imicu yotshani kusukela eksisi blade (ekugcineni lateral) futhi ingxenye clavicle. ingxenye ukulungisa - ku tuberosity deltoid we humerus. Imisipha deltoid esitho elingenhla isuswe emahlombe phandle ngaphambi kokuthatha evundlile.

round Imicu yotshani Encane

Bakha i imisipha oblong isiyingi. Ngaphambili okuyingxenye imbozwe kwezintambo zesivikelo sesifuba deltoid, ngemuva - big round. Kusukela ingalo ikhaba, kancane ngezansi Imicu yotshani infraspinatus eyakhelene ingaphezulu lalo. Ingxenye unamathele esayithini egqumeni humerus futhi egobolondweni lelunga (ubheke ingxenye esemuva yalo). Imisipha uphendulela phandle ingalo, retracts bese idonsa egobolondweni lelunga.

Imicu yotshani supraspinatus

Bakha imisipha esingunxantathu okwenyanga. Itholakala ku fossa supraspinatus ngaphansi ingxenye trapezoid. Ukulungisa indawo ngemuva kwehlombe egobolondweni lelunga inkundla ku indunduma enkulu amathambo. Imisipha liqala imigodi ebusweni. Nge zokunciphisa likhuphuka fibre futhi wadonsa kwehlombe lakhe egobolondweni lelunga, okuyinto kuvimbela Jamming.

subscapularis fibre

Basuke ezakhiwe esingunxantathu ububanzi imisipha flat. Ukotini Wekhethelo ahlelwe ku fossa chuck. Kusayithi kukhona tendinous isikhwama okunamathiselwe. Subscapularis imisipha iqala uqhatha, futhi iphela - e indunduma ezincane humerus futhi maphambili egobolondweni lelunga. Ngokunciphisa ehlombe uzungeza ngaphakathi le micu.

infraspinatus fibre

Bakha flat esingunxantathu ukuma kwemisipha. Kuyinto ingxenye ku fossa infraspinatus. Itholakala ekuqaleni fiber futhi odongeni ngemuva Chuck wakhe. It eqondiswa capsule we ngokuhlanganyela ehlombe umhlabathi ophakathi kunethiwekhi enkulu tuberosity ithambo, itholakala ngaphansi okuyinto bag podsuhozhilnaya. Cutting, imisipha ehlombe iphendula phandle, ivumela ukuthatha uhlangothi ephakanyiswe, ukudansela isiginci sakhe egobolondweni lelunga.

imisipha ehlombe

It ihlukaniswe yaba amaqembu amabili. Front wenza flexion nokwelulwa obonisa emuva ehlombe ibhodi lemisindo. Isigaba sokuqala sihlanganisa biceps, imisipha ehlombe, futhi umlomo. Isakhiwo ingxenye yesibili kuhlanganisa triceps futhi imisipha indololwane wemikhawulo engenhla yomuntu.

Imicu yotshani kabili ephethwe

Bakha imisipha uthi lokuphotha-oyindilinga. Ngo oyiyo iqukethe amakhanda amabili: esifushane, enza yabalingisi izandla futhi eside, imikhondo odala. I siqala yokugcina kusukela epiarticular tubercle izindwani. ikhanda iDemo asuka coracoid. Esikhundleni uxhumano yabo kwakhiwa esiswini is. It unamathele idolo ku engaba. ezinye zihlanganisa ulwazi izinyanda fibrous ohlangothini medial. Bakha inqubo ipuleti - the fascia. Ngokulandelayo, engena fascia brachial. Okuphokophelwe yi-biceps kuthiwa ijikelezwe out nokugoba we ibhodi lemisindo endololwaneni.

uqhwaku fibre

Bakha imisipha flat. Umbozwe inhloko amafishane ingxenye biceps. imisipha Beaked wemikhawulo engenhla umuntu uqala phezulu izindwani kwegama elifanayo inqubo. Ukotini Wekhethelo enamathiselwe ngezansi maphakathi ingxenye medial we humerus. Ngenxa yokuncishiswa ephakanyiswe ehlombe, izandla kangakanani umugca losemkhatsini esifubeni.

fibre ehlombe

Bakha ebanzi fusiform kwemisipha. Ukuqala tu- phambi emahlombe kanye ebusweni elingaphandle ithambo. Fixing wenziwa ukuba tubercle yayo kanye capsule we ngokuhlanganyela indololwane. Ukotini Wekhethelo ngokugcwele ezansi ingxenye ehlombe (ohlangothini front) by imisipha biceps.

ulnar ingxenye

Lokhu imisipha has simise pyramidal. Ekuqaleni kwalo - the epicondyle lateral wethambo ehlombe. Ukotini Wekhethelo enamathiselwe ezingemuva ingxenye yomzimba we ulna nokucubungula eponymous. Ukunciphisa, imisipha yelula ibhodi lemisindo. Iphinde uhlela ukubambezeleka capsule we ngokuhlanganyela indololwane.

fibre triceps

Bakha ingalo eside. Siqukethe 3 amakhanda: medial, ezilingene eside. Kusukela wokugcina - subarticular scapular indunduma. ikhanda Lateral isuka ingxenye posterolateral wethambo ehlombe, medial - ebusweni emuva. Izakhi axhunyiwe esiswini uthi lokuphotha emise. It ke engena umsipha. Fixing esiswini yenziwe egobolondweni lelunga futhi Scion indololwane. Nge zokunciphisa fibre flexes le ibhodi lemisindo, isandla kanye retracts ehlombe iwukuba emzimbeni. Imisipha esisogwini olecranon ukuze ukudla.

fibre ibhodi lemisindo

Bakha amaqembu amabili imisipha: the front futhi bakhulise. In ngamunye kubo kukhona fibre futhi ijulile ebusweni ungqimba. Iya eside ngaphambili iqembu kuhlanganisa flexor (ulna kanye engaba) kanye iminwe, brachioradialis ingxenye, pronator teres kwemisipha. imisipha Palmar inqobo kungokwalabo umnyango. Isendlalelo ejulile iqukethe pronator square, flexors: isithupha eside futhi umunwe ezijulile. Ukuze imisipha olukha phezulu ngemuva iqembu zihlanganisa endololwaneni, lamafisha osabalalayo extensor esihlakaleni, isithupha futhi umunwe kancane. Isendlalelo kwangempela uMnyango ukwethula instep, imisipha, lo extensor futhi nomthumbi isithupha (lamafisha), extensor index ngomunwe.

ezicutshini ibhulashi

Imisipha ahlelwe phezu Palmar. Ukotini Wekhethelo zihlukaniswe amaqembu amaningana: asho, medial, ezisemaceleni. Ngemuva ohlangothini kobuso ibhulashi kukhona igama elifanayo imisipha interosseous. Eqenjini lateral imicu akhona, ukunyakaza zokulungisa we isithupha: okungafani ukuthi yalokho, flexors kokukhwehlela. I medial kuhlanganisiwe palmaris Brevis muscle imisipha umunwe kancane. Lezi zingozi zihlanganisa ama flexor esifushane ekuholeni futhi esidayisa zesivikelo sesifuba. Eqenjini phakathi vermicular samanje, Palmar kanye amaphiko izakhi interosseous.

Ithebula. Imisipha nasemilenzeni engenhla

Sithemba ulwazi olunikeziwe kuyoba wusizo kuwe.
