Umsipha pectoral

Izihlunu thoracic Iiseli njengesakhi esibalulekileyo senkqubo musculoskeletal. Baqala apha kumphezulu ngaphambili esifubeni, ngoko hamba uye nibhinqe kweqondo eliphezulu. Ngaphezu koko, bodwa autochthonous (zakhe) izihlunu, apho iyalungiswa ukuba ezimbanjeni. Ngenxa yoko, indawo yayo yokwakheka, oko uwugcinayo intshukumo imilenze aphezulu, kwakunye inxaxheba kule nkqubo inhalation.

Ngako oko, ngezigaba, ukukhululwa izihlunu ezinxulumene imilenze aphezulu kunye nezihlunu esifubeni sakhe. Eli candelo elivumelana imisebenzi enze, kunokuba nokwakheka.

Iqela lokuqala luquka enkulu, engephi ezitsolo kunye pectoralis. Siqala zokuqala ukusuka kumphezulu ngaphambili clavicle (ecaleni layo medial), intlala imbambo yesibini yesixhenxe luphele udonga phambi imicu ngqo izihlunu esiswini. On top of esihlunwini iqhotyoshelwe kule tuberosity ngakumbi ihumerus. Iqhuba le misebenzi ilandelayo: nto leyo umlenze eliphezulu ukuya umzimba, baze bajike ngaphakathi, imicu, leyo ezikufutshane clavicle, ebandakanyekileyo flexion esandleni. Kananjalo inxaxheba kule nkqubo inhalation. Ukuza kuthi ga ngoku, imilenze ephezulu kufuneka bunikwe umzimba, ayinakutshintshwa. Kananjalo inxaxheba brachiation (etsala).

Pectoralis minor ibekwe phantsi enkulu. It evela ubambo yesibini sesihlanu kudlulela, iqhotyoshelwe inkqubo blade. Muscle owenza le misebenzi ilandelayo: ngoxa kuncitshiswa lopatkuv siyakrazula phambili kunye nolwalathiso phantsi. Xa ukulungisa isandla oko inxaxheba kwinkqubo uphefumlayo.

Subclavian izihlunu pectoral ephakathi clavicle kunye iimbambo kuqala. Iqhuba le misebenzi ilandelayo: nitrogen kokudityaniswa sternoclavicular, bawurhuqa clavicle medial kunye phantsi.

Front serratus kumntu wonke loo mmandla lateral thoracic. Ivela ekupheleni eliphezulu ezisithoba, ke eqhotyoshelwe ukuya kwikona engaphakathi ikhaba. Kunye naye kule Isiphelo umsipha rhomboid, nto leyo ebangela ukufana imisebenzi yabo apha. Ezi ziquka ukulungisa iincakuba, khawulitshitshise kwisahlulo esezantsi amathambo yokuxazulula kwaye phambi koko bakubona xa uphakamise ingalo ilayini ngasentla tye.

I zangaphandle nezangaphakathi intercostal pectoral kwezihlunu kukho izihlunu okunexabiso kule ndawo. Bona zigxunyekwe cartilages costal. Umahluko zihlunu lwangaphandle kunye lwangaphakathi kwimicu zabo. Kuba uphawu yokuqala ulwalathiso emva naphambili phezulu phantsi. imisipha lwangaphakathi intercostal kufuneka ikhondo malunga liqine ukuba zifike kwentamo. Noko ke, ukuba enze umsebenzi ofanayo.

Podrobernye nezihlunu nazo ngamalungu eli qela izihlunu zakhe. Bona elise kwicala elingaphakathi umphongolo inxalenye engezantsi kwayo. Podrobernye izihlunu zincamathele emasondweni emiphethweni. Le peculiarity lekhosi Imisonto yabo ugibisela ngaphandle ezimbombeni zaso ezimbini.

imisipha Lower pectoral (enqamlezileyo) ibekwe phezu yangaphakathi kwaye kunxulumene neqela izihlunu zayo. Kuye intshukumo ethe nkqo ye imicu. Oku izahlule onke amaqumrhu zelo qela.

Zonke izihlunu zakhe esifubeni ababandakanyekayo ukuphefumla. Lo msebenzi zazo eziphambili. Muscle yonke iimbambo esifubeni iyavuleka kuwo onke amacala. Ngenxa yokuba wenziwe umpefumlo. Ngumphunga kwenzeka nje, oku kunegalelo luthambe esifubeni sakho, emiphungeni. Kukho ithiyori ekuthi ngawo izihlunu intercostal lwangaphakathi ukuthatha ekuphunyezweni olwandle. Kodwa onke amaqumrhu le hlobo igalelo kukhulu kwesenzo yenza uvalo.

Nawuphi umsipha pectoral yi imfundo ibalulekile, ukususela, ukongeza kwimisebenzi iimoto, lenza umsebenzi sokuphefumla.
