Imisipha ehlombe, ngemilenze kanye nebhande ehlombe

Ehlombe ibhande siqukethe amathambo ezintathu: clavicle, scapula, humerus ithambo (thambo elingenhla ingalo), kanye imisipha, nemisipha futhi imisipha. Ehlombe sele emalungeni ezithathekayo phakathi amathambo ehlombe. Emisipheni nasemalungeni kukhona ehlombe uyivumele ukuhambisa etinhlotjeni letibanti kusengaphambili ezinyakazayo. Imisipha ehlombe kwebhande ehlombe banesibopho ukuhamba scapula, humerus, futhi clavicle. Ngaphezu kwalokho, le misipha ibunjwa ehlombe, joint ehlombe kanye axillae (emakhwapheni). Ngokwesibonelo, nentaba oyindilinga ka joint ehlombe Kumiswa imisipha deltoid. Anatomically, limelela ahlukene imicu kabani msebenzi esihlelwe isimiso sezinzwa esiyinhloko.

ehlombe Human - kuyinto engxenyeni engenhla ingalo imisipha namathambo, esiphakathi ehlombe indololwane amalunga omzimba. I mkhawulo ehlombe - umugqa transverse of onqenqemeni engezansi pectoralis ezinkulu, teres imisipha ezinkulu ezibanzi imisipha emuva. Umkhawulo engezansi amanga ngenhla (2 transverse umunwe) we condyles we humerus. imisipha ehlombe ahlelwe Laphezu nangemuva kwe-humerus. Ngaphambili iqembu imisipha ebizwa ngokuthi biceps (ngesiLatini - musculus biceps brachii) noma izikhwepha zomfana. imisipha posterior iqembu - triceps (ngesiLatini - musculus triceps brachii) kanye triceps.

izicubu ziqinile futhi nokunwebeka (lwamathambo, noma-ke ubizwa nangokuthi striated) ukuthi yenza imisipha ehlombe, sibonga ikhono lazo ukunciphisa emsipheni amaza. Ngenxa yalezi izakhiwo kwemisipha izicubu kuyinto ukunyakaza endololwaneni kanye triceps futhi biceps banesibopho lezinhlangano. Ngaphezu kwalokho, zombili lezi imisipha ukucacisa ukuma ehlombe, okuyinto kuncike degree yokukhuluphala yomnqumo futhi imisipha. Ngenxa amafutha ongama ezinganeni nabesifazane eshelelayo imifanekiso kwemisipha ingalo has a close ifomu ukuze uMbhalo lesifanele. Ngo amadoda esinevolumu enkulu ehlombe kwemisipha engxenyeni engenhla kuka endaweni akhelene indololwane.

igama elihlanganyelwe we biceps - biceps - lisuselwa emagameni amabili Latin: bis, okuyinto uhumusha njengoba kabili, futhi caput, okusho ikhanda ukuhumusha. Biceps (ezimbili imisipha besigaxa) sinamakhanda ezimbili, yokuxhuma phakathi ihlombe okuvame kwemisipha yesisu. Inhloko eside unamathele ikhaba (maholoholo epiarticular agcwalise) umsipha kokuqala. ikhanda iDemo futhi iqala kusukela ikhaba (inqubo coracoid). Biceps enamathiselwe phezulu ibhodi lemisindo umsipha ekupheleni, kulo esiswini Imininingwane. Umsebenzi oyinhloko lokhu imisipha kuyinto flexion we ngokuhlanganyela indololwane esandleni. It is innervated ngu emsipheni kwemisipha cutaneous.

igama elihlanganyelwe kwemisipha triceps - triceps - futhi lisuselwa emagameni amabili Latin, owokuqala babo (tri) ezintathu, kanti eyesibili (caput), njengoba iye echazwe ngenhla. Lena imisipha emikhulu cishe 2/3 isandla imisipha futhi unesibopho eqondisa (eqondisa) ingalo endololwaneni, joint indololwane ibuye ithumba lapho ibhodi lemisindo futhi asetshenziselwa ukunyakaza esihle, ezifana uma ubhala. Siqukethe izinyanda ezintathu kwemisipha izicubu iqala amakhanda ezintathu (eside, medial kanye lateral), futhi bukhomba eyodwa umsipha indololwane. Classically, kunenkolelo yokuthi bonke amakhanda ezintathu imisipha triceps is innervated ngu emsipheni osabalalayo. Nokho, kukhona imiphumela izifundo ezikhombisa ukuthi innervation kungenzeka igatsha emsipheni axillary.

ibhodi lemisindo Human kuyinto ingxenye uhlangothi, esemgwaqweni phakathi ngokuhlanganyela indololwane kanye esihlakaleni (eyaziwa nangokuthi i-esihlakaleni). I ibhodi lemisindo siqukethe amathambo amabili nemisipha (ulnar futhi osabalalayo). kwakhiwa Muscle izicubu is of ezine zamatshe imisipha, okuyizinto phambi panel, kanye ezimbili zamatshe amaqembu kwemisipha emuva. Waba yini umphumela wesibindi umsebenzi wabo ukuhamba ngezandla (kuhlanganise phalanges) kanye esihlakaleni. Ngokuvamile, imisipha ehlombe ibhodi lemisindo ukunikeza ezihlukahlukene ingalo ukunyakaza, ngemilenze nezandla.
