Ubume kunye nomsebenzi zomuntu

Muscle sisigqeba elithile umntu okanye isilwanyana. Siqulathe laphu kokuba ikhono nciphisa phantsi isiphumo neemvakalelo-luvo. Okulandelayo, cinga isakhiwo kunye nomsebenzi izihlunu zolwimi ngokunzulu. Eli nqaku liza kunikwa ukuhlelwa izihlunu.

nokwakheka

Izihlunu thaca ngokohlobo kwizihlunu ezithambileyo, eliquka imicu ezahlukeneyo. Bakhululeke contract. Umsipha iye iinyanda striated izakhiwo (striated). Ezi Imicu kuqhutywa kunye nenye. Banxibelelana ngokusebenzisa kwizicwili kwaye enze imiqadi lokuqala-oda. Uninzi lwazo iqhagamshele. Nabo ke, benza iinyanda ukuze 2. Ngenxa yoko, onke la maqela ukuba iqokobhe dystrophy abamanyeneyo, ngokwenza 'isisu. " Zikhona phakathi imiqadi umaleko nokuqina. Watyhutyha ilizwe ekupheleni esiswini, aye izihlunu ndawo imicu.

Iinkqubo ngaphakathi ifayibha: isishwankathelo

Ekubeni ukwehla kubangelwa yi fikelela CNS isantya, ngoko ngamnye luvo kwezihlunu imke: afferent kunye efferent. Eyokuqala ingqalelo (ngokwe Pavlov) le analyzer motor. Bachitha "ingqiqo dystrophy." Efferent luvo angxamele kukhokelela imicu. Ukongeza, izihlunu uvumelane neziphelo novelwano. Enkosi kubo, imicu ezi kwimilo elungileyo - yimeko nokuncipha kancinane. Xa izihlunu zenzeka iinkqubo esebenzayo kakhulu metabolic. Kulo mba, eli laphu unobuxhakaxhaka semithambo olubanzi. amajelo igazi gaze kwicala ngaphakathi kwi ingalo kumaziko omnye okanye ngaphezulu. Le ndawo kuthiwa emasangweni. Kule mimandla, kunye neempahla igazi kwizihlunu, uze ufake luvo lwamasebe ngaphandle kunye nemiqadi, ngokulandelelana - liphela kunye.

iinxalenye esikule

Xa imisipha, ukwahlula esiswini - inxalenye esebenzayo ye imicu - into nje. Ngoncedo ingalo yokugqibela zigxunyekwe ithambo. Imicu inikwa ngokohlobo kwizicwili, ashinyeneyo ngokwaneleyo, ukuba umbala shiny yegolide ukukhanya ukuba asifani Tint esisu bubomvu-mdaka. Ngokuqhelekileyo, imicu kubekwe zombini kungqameko izihlunu. Maxa wambi kuba mfutshane kakhulu. Kwiimeko ezinjalo, kubonakala ukuba izihlunu enambuzelayo ngqo ithambo okanye eqhotyoshelwe kuso esiswini sakhe. Ukuthenga migqomo imicu, apho ngaphantsi ukutya ahlwempuzekileyo. umsipha skeletal iquka kuphela striated kwithishyu. Kuyo kukho iintlobo ezahlukeneyo nokuqina, luvo, imicu agudileyo kunye endothelium. Noko ke, oko loyise nangoku striated kwithishyu. phawu lwakhe - contractility - kwaye ichaza imisebenzi ngamalungu oluntu ezifana izihlunu ukusikwa. imisipha nganye umzimba elahlukileyo yinto kumiswa ezifunekayo. Ngamnye kubo isakhiwo yakhe azalwa wayo, imilo, indawo kunye nophuhliso. ukukhathalelwa komntwana ngamnye, ingakumbi, eba umsebenzi zomuntu.

imisipha ukuba isebenze

Phantse wonke umntu uyazi ukuba umsebenzi wenziwa izihlunu. Kakade ke, lo intshukumo software. Eyona impahla izihlunu zomzimba - contractility. Uthando luyakha kunye nomsebenzi kwezihlunu. Xa inkqubo yokunciphisa ifayibha kunciphisa kwenzeka kunye ukuhlangabezana iingongoma ezimbini attachment. Kwezi nxalenye ezimbini ezihambisekayo umdla ku static. Isiphumo sale nkqubo isiphakamiso ngozi komzimba. Ngokwenza isenzo esichazwe, umsipha uvelisa ubungqongqo a amandla ethile. Ukuhambisa umthwalo, umzekelo, ubungqongqo wethambo, umsipha owenza umsebenzi ngoomatshini.

iimpawu imisipha

Inani kwimicu ezakha izihlunu, lekeyboard lithetha amandla ayo. Kwakhona ebalulekileyo yi ariya "ubudeki nokomzimba." It wakunciphisa kule ndawo, ngalo lonke imicu kwezihlunu. Ubukhulu ngokucuthwa ixhomekeke ubude kwezihlunu. Bone obonisa intshukumo kwamalungu phantsi amanyathelo izihlunu, ezi zokuxhathisa (ngengqiqo mechanical). Zingakotshwa ngokuba oomatshini elula ukususa izinto ezisindayo.

Le bokuqonda uthimbo ifayibha

I kude ezikude indawo inkxaso iza izihlunu, ngoko kuya kuba nenzuzo. Oku kungenxa yokuba i-mkhulu ingalo lever, ngcono amandla esetyenzisiweyo. A ngokuhlelwa ukusuka kwindawo yoku Lesgaft, simele babantwana mabawuqonde umahluko phakathi:

• imisipha. Bona apha kude inxalenye inkxaso.
• Obuchwepheshe. Ezi Imicu iyalungiswa elisecaleni isabelo inkxaso.

kwezihlunu ngalinye isiqalo attachment. Ixhasa umzimba kwalapho. Le elise osembindini ahlangene yomzimba. Ukuqalisa izihlunu kudla ingqamana indawo esisigxina. Ku ibekwe kufutshane indawo ephakathi, naphezu imilenze - ukuya buti (proximal). Ukulungisa imisipha, leyo ingqamana isahlulo ezinokususwa ibekwe ezikude embindini. Kwi imilenze, ngokulandelelana, isiza uthimbo distal, kude ukusuka umntla. izabelo ezinokususwa nezinto zokubhala ukuze kubuyela ebutsheni. Oku kwenzeka kwimeko nokukhululwa yencopho elimisiweyo. Kwakhona, ukutshintsha kweendawo uyaqapheleka ekomelezeni isabelo eshukumayo. Unako ukubona umzekelo ukuma. Kule ndawo inxalenye ezinokususwa ngqo izihlunu esiswini kuba buthelezi yabo eliphezulu - ukugobeka iya kuba kwisiqingatha ongentla umzimba, yaye vice phezu kwepali enqamlezileyo phezu kwezandla - ukuphela asezantsi.

Abamelene kunye synergists

Ekubeni intshukumo yenziwa kumacala amabini malungana - cast, ukuthwala, flexion-ulwandiso, - ukwenza iintshukumo malunga naziphi umgca olunye kufuneka inxaxheba ukuba izihlunu ubuncinane ezimbini. Kufuneka ibekwe ngapha nangapha. Izihlunu, nto leyo ethatha indawo kumacala angafaniyo, zibizwa ngokuba abachasi. Ngexesha ukugoba nganye wawungapheleli flexor kuphela, kodwa extensor. Last kuxhaphaka unika indlela eya kuqala. Extensor flexor egcina ukusuka nokuncipha ngokugqithiseleyo. Ngokuphathelele oku, awunandaba ikhuthaza ukulingana kwezihlunu neentshukumo egudileyo. Ngokungafaniyo izihlunu kuchaziwe, nomphumela ka edulusele kwicala elinye, nezaziwa synergists. Kuxhomekeka indlela onesimilo ukuba loo intshukumo noko indibanisela zihlunu ezisebenzayo inxaxheba kuyo, isakhiwo esifanayo kunokuba zombini bachasene kunye agonists (synergists).

imisebenzi utshintsho

Le nkqubo ugcinwe esiphilayo kwaye igqalwa eyongeziweyo lobeko lwe eqhelekileyo. umsebenzi kwemisipha iyevakala kuchazwa zomzimba ngokunxulumene wabo axis ngqo ngokubambisana ujikelezo. Utshintsho zikwimeko kwemisipha okubangelwa lokugcina omzimba kunye nemimandla yawo ngamnye, narhoqo ezahlukeneyo umthwalo manani kunye neguquguqukayo kwisixhobo motor. Ngenxa yoko, umsebenzi kwezihlunu yatshintsha ngokuhambelana indawo emzimbeni (okanye ummandla apho inyathelo) lesigaba kunye neentlobano efanelekileyo eshukumayo.

ngezigaba izihlunu

Ngokuhambelana kunye nemisebenzi eyenziwa yi izihlunu zahlulwe extensors, ukugoba, ebangela kusabiwa. Kukwakho ke rotators. Izihlunu, ngelixa kuncitshiswa imilenze apho lihamba kude umzimba, ebizwa ziphazamiso. Izihlunu, approximating ukuba umzimba, kuthiwa phambili. Rotators zinika ujikeleziso omnye okanye elinye ilungu lomzimba indlebe. Xa umzimba, kukho izihlunu intloko, imilenze, esifubeni. Makhe sihlolisise ngokweenkcukacha.

esiqwini

Kule yinxalenye yomzimba iqulethe izihlunu esiswini, emva kunye nesifuba. Le yokugqibela ziquka izihlunu intercostal zangaphakathi nezangaphandle kunye uvalo. Ngoncedo lwabo bamthwala umoya. Umsebenzi izihlunu esiswini zinika flexion yomqolo kwicala, phambili nijike axis yayo. Bakha izihlunu esiswini. amanxeba akhe ukukhuthaza kukhuthaza umchamo kunye isitulo, umoya, isenzo generic. Surface (latissimus kunye trapezius) nezihlunu emhlane zinika intshukumo nokomeleza izandla kunye nomlenze nombhinqo. izihlunu Deep ukulungisa umnqonqo, ukugoba, unbend oko. Ngoncedo lwabo, njengoko kukho njengokujikeleza entloko, ukuphefumla iintshukumo.

ezizitho eliphezulu

Kukho amaqela amabini izihlunu uya langoku. Imicu umsipha ekwanti ye umbhinqo emagxeni. Ezi ziquka esifubeni amancinci, isakhiwo enkulu kunye deltoid. Zinika ukuhamba kuyimfuneko. Imisebenzi izihlunu ngesa- zisasazwa kuxhomekeke indawo. Imiphezulu aphambili la iminwe kunye ukugoba esihlahleni. Imisebenzi Ezomva womgca izihlunu ziyenza njani zezi obungenakuzanyazanyiswa. Ngenxa kwizihlunu ngokusebenzisa iintlobo weentshukumo ngesandla.

Imisebenzi izihlunu entloko

Musculature umzimba yahlulwe ngamaqela amabini - bakope kunye ihlafuna. Imicu isiqalo yokugqibela ekupheleni amathambo kunye cheekbones njo emhlathini asezantsi. Imisebenzi izihlunu intloko ngomva kuquka ekukhuliseni kwemihlathi yangasentla. Oku kuqinisekisa mastication. imisipha ukulingisa ababandakanyekayo amazwi iimvakalelo. Umsebenzi izihlunu setyhula ibekwe macala usikrobana iliso Neenkophe ezivaliweyo. Emabunzini abo imisipha ngokungqalileyo. Kufuphi emlonyeni ibekwe orbicularis oris kwezihlunu. Musculature yaye ukho kwindawo izibilini. Ngokufutshane ichaza umsebenzi izihlunu kunye etafileni yabo;
