Marongerwo uye basa mhasuro kwevanhu

Muscle ndiyo imwe sechivako munhu kana mhuka. It rine jira chine kugona ndizvipete pasi nezvaizoitwa etsinga nomunhu. Next, funga marongerwo uye kushanda tsandanyama zvizere. Nyaya achapiwa chinhu kupatsanura pakati netsandanyama.

anatomi

Tsandanyama dzinoturwa muchimiro nyoro zvinyama, zvinosanganisira yoga fibers. Vavanogona kutandara uye chibvumirano. The tsandanyama ane tsapo ose striated (striated) zvivako. fibers izvi kumhanya newokuti mumwe. Vachikurukura pachishandiswa connective zvinyama uye dzinoumba vokutanga-hurongwa matanda. Vanoverengeka vavo zvakabatana. Ivowo, zvinoumba tsapo kurongeka 2. Somugumisiro, mapoka aya ose vakabatana tsandanyama goko, kuita "dumbu." Varipo pakati namatanda connective rukoko. Nomunyika kuguma mudumbu, ivo kune tsandanyama ose mudzira nzvimbo.

Pezvakaitwa mukati faibha: muchidimbu

Sezvo rutapudzo iri kukonzerwa nokusvitsa CNS tichimhanya, zvino mumwe tsandanyama tsinga kuenda: afferent uye efferent. Chokutanga vaiona (maererano Pavlov) of injini analyzer. Vanopedza "tsandanyama pfungwa." Efferent tsinga zvairatidza kunotungamirira kune fibers. Mukuwedzera, tsandanyama kukodzera tsitsi harinzwi. Pamusana kwavari, ivo fibers vari akanaka chimiro - ezvinhu nezvenyaya marwadzo. In tsandanyama kuitika chaizvo kushingaira metabolic kwendangariro. Panyaya iyi, chinokosha ane yakakura vascular Network. Ropa Mipata chichipinda divi romukati riri ruoko pane imwe kana kupfuura nzvimbo. Nzvimbo idzi ndidzo dzinonzi masuo. Munzvimbo idzi, pamwe chete nemidziyo ropa tsandanyama, uye ipapo kupinda tsinga nebazi panze uye matanda ukuwo - mhiri uye pamwe.

zvikamu zviri tishu

In tsandanyama, kusiyanisa mudumbu - zvinoshingaira chikamu mudzira - kungotarisa maatomu akafanana. Tichibatsirwa ekupedzisira ruoko ndee kuna mafupa. The mudzira anotaurwa muchimiro connective zvinyama, gobvu zvakakwana, ane chiedza yendarama kupenyerera ruvara kuti anosiyanisa zvikuru pamwe yakatsvukuruka mashava tint dumbu. Kazhinji, asi mudzira riri vose micheto tsandanyama. Dzimwe nguva pfupi chaizvo. Muzviitiko zvakadaro, zvinoita sokuti tsandanyama kunoita zvakananga kubva pfupa kana zvakabatanidzwa nayo dumbu rake. Ichitenga mudzira pangagara, sezvamakaropafadzwa zvishoma muviri rourombo. Skeletal tsandanyama kunosanganisira kwete chete striated tishu. Mariri panewo akasiyana siyana connective, tsinga, ganda fibers uye endothelium. Zvisinei, izvozvo rikunde achiri striated tishu. Her chinhu - contractility - uye inorondedzera mashandiro kwevanhu nhengo akafanana tsandanyama marwadzo. Mumwe tsandanyama chinhu chakaparadzana muviri kuti chinhu chinokosha inotungamirwa. Mumwe nomumwe wavo ane yayo yokusafa yakarongeka, chimiro, chinzvimbo uye kubudirira. Individual nzeve, kunyanya, iro rine mashandiro tsandanyama kwevanhu.

tsandanyama kushanda

Anenge munhu wose anoziva basa rinoitwa nevanhu tsandanyama. Chokwadi, ichi Software kufamba. Huru tsandanyama rinenge pfuma - contractility. It anovaka uye tsandanyama basa. Mukuita kuderedza internet kupfupikisa kunoitika uye convergence zviviri pfungwa kuda. Of zvikamu izvi zviviri chinjwa mwoyo kunofambira mberi. Mugumisiro izvi ndiko akafanorongerwa inofamba muviri. Nokuita munhu zvinorondedzerwa chiito, kuti tsandanyama unobereka kwokuomerwa imwe simba. Kufambira mutoro Somuenzaniso, kwokuomerwa pfupa, kuti tsandanyama anoita zvokuimba basa.

Features tsandanyama

Kuwanda fibers anoumba tsandanyama, anosarudza simba raro. Uyewo kuti zvikuru kukosha ndiyo nzvimbo "vasiri dhayamita." It kucheka kukura munharaunda, iyo zvose zviri tsandanyama fibers. Kwakakura pamusoro rutapudzo kunoenderana tsandanyama kureba. Bone anotenda sangano iri majoini pasi kuitwa tsandanyama, muri levers (ari zvokuimba mupfungwa). Vanogona kunzi nyore michina kufamba rinorema zvinhu.

The nuances of internet kuda

The kure nokutsigira nzvimbo achaparadzwa wakaiswa tsandanyama, saka zvichava nani. Izvi imhaka yokuti kunokonzera mhikuriso ruoko, nani simba rakashandiswa. A kupatsanura kubva pfungwa nemaonero Lesgaft, tinofanira kusiyanisa:

• tsandanyama Strong. Vari dzakabatanidzwa kubva nokutsigira mugove.
• Dexterous. fibers aya ngadzirambe pedyo rubatsiro mugove.

Mumwe tsandanyama ndiwo mavambo uye kubatana. It anotsigira muviri wose ndiyo nomuzongoza. Riri pamusoro midline muviri akabatana. Kutanga tsandanyama Kazhinji rinobatana yakatarwa pfungwa. Riri pedyo nepakati chikamu, uye pamusoro makumbo - kuti hunde (proximal). Kugadzira tsandanyama, rinobatana ari pamwe chinjwa mugove yaiva kure kubva pakati. On maoko nemakumbo, ukuwo, kuda nzvimbo iri distal, kure kubva mutumbi. migove chinjwa uye mira zvinogona kuchinjwa. Izvi zvinoitika panyaya pakabudiswa yakatarwa pfungwa. Uyewo, kuchinja nzvimbo iri kwakacherechedzwa pakusimbisa chinjwa mugove. Unogona kuona muenzaniso yakamira. Panzvimbo iyi chinjwa mugove twasu abdominal tsandanyama kuva kwavo yokumusoro pamupendero - vachikotama ichava yokumusoro hafu muviri, uye panguva vise pamusoro kwepuranga rakachinjika pamaoko - rezasi magumo.

Mhandu uye synergists

Sezvo sangano iri kuitwa mbiri pakatarisana mirayiridzo - chakakandirwa, kutapa, flexion-Tingawedzera - kuti aite masangano kumativi chero akabatana kuroora vanofanira kubatanidzwa kuti tsandanyama dzinenge mbiri. Vanofanira riri kumativi akasiyana. Tsandanyama, zvinotora nzvimbo wakatarisana mirayiridzo, vanonzi mhandu. Panguva imwe neimwe vakafugama rinobatanidzwa kwete flexor chete, asi extensor. Last kupiwa zvishoma nezvishoma nzira kune wokutanga. Extensor flexor anoramba rokurara marwadzo. Maererano daka ichi kunoita tsandanyama proportionality kumeso kufamba. Kusiyana tsandanyama zvinorondedzerwa, Pamusana iyo iri imwe nhungamiro, anonzi synergists. Zvichienderana sei chimiro ane kana kuti kufamba uye chii wemishonga dzichipfekeka tsandanyama kubatanidzwa mairi, ndiye mamiriro kunogona mhandu uye agonists (synergists).

chinja mabasa

Izvi zviri kuchengetwa chipenyu Muviri kunoonekwa sechinhu musiyano pakati vasingambooni chakaipa nazvo. Elementary tsandanyama basa rinotsanangurwa anatomic ukama hwavo yakananga pamwe akabatana kuti kutenderera. Aichinja tsandanyama ezvinhu kwakaita kuramba uinacho muviri chinzvimbo uye wayo mumwe zvikamu, uye akaramba kusiyanisa Statistical uye simba mutoro pamusoro injini midziyo. Saka, tsandanyama basa zvakachinja zvinoenderana nzvimbo muviri (kana mapazi panguva iyo chiito) danho uye yakakodzera inofamba kurara.

kupatsanura pakati tsandanyama

Maererano mabasa anoitwa tsandanyama vari rakakamurwa extensors, flexors, zvichiguma allocating. Panewo rotators. Tsandanyama, apo achidzikisa maoko nemakumbo ayo kutama kubva pamuviri, rinonzi yeRwizi. Tsandanyama, approximating kumuviri, anonzi kutungamirira. Rotators zvinopa majana mumwe kana chimwe muviri. Mumuviri, pane tsandanyama musoro, maoko nemakumbo, mutumbi. Ngationgororei navo zvizere.

hunde

Muchikamu ichi muviri rine abdominal tsandanyama, musana uye chipfuva. Ekupedzisira zvinosanganisira zvemukati uye zvokunze intercostal tsandanyama uye diaphragm. Uchibatsirwa wavo vakatakura mweya. Zvaiitwa abdominal tsandanyama zvinopa flexion pamusoro musana kurutivi, mberi uye vatendeuke akabatana kwayo. Vanoumba abdominal netsandanyama. mavanga ake kutsigira excretion kuti weti uye chetsoka, befu, ari Generic chiito. Pamusoro (latissimus uye trapezius) tsandanyama ari shure zvinopa sangano uye kusimbisa maoko uye fudzi nebhanhire. Deep tsandanyama zvigadzirise nomuzongoza, vanobwembura, unbend nayo. Uchibatsirwa dzavo, sezvo pane kutenderera musoro, kufema masangano.

okumusoro nemakumbo

Kune mapoka maviri tsandanyama aripo. Kure tsandanyama fibers pamusoro pamafudzi nebhanhire. Izvi zvinosanganisira bhokisi diki, hombe uye deltoid marongerwo. Zvavanokupai zvakakodzera kufamba. Mashandiro anoita mashoko honokono tsandanyama anoparadzirwa zvichienderana nzvimbo. The pamberi hukawanika ndivo minwe uye chiningoningo flexors. Mashandiro anoita rwemberi ndege yacho honokono tsandanyama vakaita vasingachinji. Nokuda tsandanyama kuburikidza dzakasiyana-siyana-fambisa maoko.

Mashandiro anoita musoro tsandanyama

Musculature muviri rakakamurwa mapoka maviri - kutevedzera uye dög. Fibers okupedzisira kutanga kumucheto pfupa uye cheekbones vari nde rezasi shaya. Mashandiro anoita musoro posterior tsandanyama ine pakurera yokumusoro shaya. Izvi zvinoita mastication. Sezvimwe tsandanyama zvinobatanidzwa kutaura manzwiro. Zvaiitwa dzeraundi tsandanyama yaiva kumativi ziso panosangana riri Akanyatsovharwa kukotsira. Pahuma ndivo frontal netsandanyama. Pedyo muromo yaiva orbicularis oris tsandanyama. Musculature uye aripo mune zvomukati. Muchidimbu anorondedzera mashandiro tsandanyama uye tafura dzavo:
