Hanganga me te whakarōpū o te uaua tangata

Uaua - Ko reira he huānga kaha o te pūnaha musculoskeletal.

kawea Whakarōpū o uaua i roto i runga i whenua rerekē: te āhuatanga i roto i te tinana tangata, te āhua, te aronga o te muka, i te mahi e pā ana ki te hononga, me ētahi atu

Ko te momo matua o te uaua

Whakarōpū me te uaua whai tuaiwi tangata kōrero i te aroaro o ngā momo rerekē e toru: striated uaua kōhiwi, striated uaua cardiac (myocardium) me te uaua maeneene o e nga taiepa o oko toto me whekau tuwhera.

Wāhui o uaua striated ko ki te kawe i te wheua ki te neke, te whai wāhitanga i roto i te hanganga o nga taiepa o te mangai, uma, puku. Ko wāhanga o te wahi tautoko o te okana kanohi ratou, pā te ossicles māna. Mahi uaua kōhiwi whakarato pupuri i roto i te taurite tinana ki te neke i roto i te wāhi, kuru o nekehanga romahā me te horomia, te aroaro o kīanga kanohi.

uaua kōhiwi: Hanganga

Tata 40% o te taimaha tinana pakeke he tika kiko uaua. uaua kōhiwi i roto i te tinana 400.

Unit o uaua kōhiwi - ko te motoneuron me nga muka te uaua innervated e tenei wae neuromotor. tonoa Mā te ngātere mai motoneuron ki muka uaua mahi.

aroaro uaua kōhiwi he maha nui o muka uaua. E ratou he āhua elongated. kōrero Whakarōpū o te uaua tangata e to ratou diameter ko 10-100 microns, a ka pae te roa i 2-3 ki te 10-12 cm.

karapoti pūtau uaua te membrane kikokore - sarcolemma ngā sarcoplasm (protoplasm) me te tokomaha nui o karihi. wahi Contractile o te muka uaua kanohi whenu uaua roa - myofibrils, e ngā nuinga o te actin taonga i huaina.

roto Myosin te i roto i te pūtau, he mea i roto i te āhua dispersed. He he rota o te pūmua, e whai wāhi nui i roto i te whakaū i te hukihuki toniki. e kore e ara te marino whanaunga o te uaua kōhiwi tikanga tona whakangā oti. I tenei wa puritia te ngaohiko āhua, arā, oro uaua.

taonga Houalotú uaua

Hanganga me te whakarōpū o te uaua kōhiwi meinga ratou taumahinga. Ko te kupu, anake e taea e ratou te mahi i etahi mahi mā ngā hanganga kikokiko motuhake, me te whai wāhi mai whakatu nga mihini pŭpŭ tauturu, e ngā o fascia, iohere takotoranga, peke synovial me poraka. Fascia Ko te hipoki, e ngā o kiko tūhonohono, whakarato tautoko uaua puku ka kirimana reira, te ārai uaua waku motu. I roto i te take o te aroaro māuiuitanga fascia ārai te horapa o te pirau, me te toto i te pakaruhanga toto.

Whakarōpū o uaua kōhiwi o te āhuatanga hihiri me te pateko

uaua kōhiwi, i runga i te pūtake o te āhua o whanaunga i waenganui i paihere uaua, me te intramuscular ngā kiko tūhonohono, kia rerekē nui i roto i te hanganga, e whakatau ratou kanorau mahi. Uaua kaha e taea te whakaritea e te maha o paihere uaua, rite whakatau ratou te uara o te diameter whaiaroaro. Ko tona huru ki te wāhanga ripeka kikokiko ko ki te whakawa i te kaha rerekē o te āhuatanga hihiri me te pateko.

Whakarōpū o uaua kōhiwi o te rerekētanga i roto i enei whanaunga tuwhatuwhaia uaua kōhiwi ki hihiri, pateko-hihiri me te pateko.

he angamaheni hoki uaua hihiri te hanganga māmā. Ki te reira te mea he ngawari peremiziya ratou muka roa haere haere te tuaka wä roa o te uaua ranei i te koki ki reira, e arata'i ki te tāpiritanga o te wāhanga ripeka kikokiko ki saline. Ēnei uaua te mahi te nuinga o te kawenga hihiri. E ratou he kaha tīwera nui, engari te kaha, e kore ratou e rerekē. E whakaaro ēnei uaua ki te kia nohopuku, kakama, engari hohoro potae.

I roto i te uaua perimysium statodynamic (roto, o waho) e atu tino whakawhanakehia atu e o te hihiri, me nga kaka uaua poto. haere ratou i roto i ngā tohutohu rerekē, t. E. Puka, pērā hihiri, maha ngā whānuitanga whaiaroaro. Ki te kahore he kia kotahi noa whanui kikokiko i roto i te uaua e 2, 3, ranei 10 ngā whānuitanga whaiaroaro. kōrero ana tēnei e uaua statodynamic kaha hihiri. Ratou tūranga he tino ki te mau tonu i te mahi pateko i roto i te tautoko, te pupuri ki te tika i te hononga i runga i tu. E āhuatanga ratou e nui te kaha, me te nui haamahu.

Whakarōpū o uaua fakahu'unga te oraraa o te momo tuatoru. Tenei uaua pateko. kia whakawhanake ratou i roto i te akoranga o taka he kawenga nui pateko i runga a ratou. Ko te raro te wāhi o te uaua i roto i te tinana, te atu rerekē ratou i roto i ngā o te hanganga pateko. Te nuinga mahi pateko i tu me te i runga i nga wahi tautoko whenua i roto i te nekehanga, e whakakaha ana hononga i roto i te tetahi tūranga he wahi o ratou mahi tika.

Whakarōpū o uaua i roto i te ahunga o nga weu uaua me ratou pā ana ki te tendons

Uaua muka e e whakaritea whakarara ki te tuaka wä roa, ka karanga muka-ahuahu whakarara ranei. A, no te Ko nga muka i te koki ki te tuaka, ka karanga he uaua matahuru. E paetata nga wahi nuinga tika spindly me matahuru uaua.

layer iohere Intramuscular, engari te maha, me te aronga o te paparanga uaua ko nga paearu i runga i nei e wehea uaua matahuru ki te maha momo:

• semipenniform i nei kahore iohere interlayer, uaua āpitihanga ki te muka io, i reira he kotahi anake ringa;
• dvuperistye; to ratou kotahi apa tendinous me te hononga e rua-ara ki te iohere o te muka uaua;
• mnogoperistye nei E rua, neke atu rānei kahu o te uaua i memenge, i te mea he aha i reira te i whiria, o paihere uaua, whakatata ratou te iohere i te maha o taha.

Me pēhea te ki te wehe i te uaua i roto i te āhua?

Whakarōpū i te puka o te uaua miramira ratou kanorau i roto i te torutoru momo taketake.

1. Roa. Kei te nuinga i roto i te wahi. Ratou āhua rite te muka. Kei te wehea ia uaua e toru nga wahi, ka karanga te wahi waenganui ko te kopu; timata o uaua i huaina te matenga ritenga te mutunga runga - ko te hiawero. Ratou tendons he āhua rīpene-rite. He uaua te roa e whai kore tetahi engari e rave rahi matenga o ngā wheua, he mea e tika ana ki te whakapiki ake i ō rātou tautoko. E huaina ēnei uaua maha-upoko.
2. Poto. Ko ratou te wahi e kore e rawa ratou nekehanga tauine nui. Tenei tuu te wāhi pūhui pekehoe takitahi i waenganui i te pekehoe me rara, me ētahi atu
3. Flat whānui. E tū ana te nuinga i runga i te kātua me whitiki o runga me pito o raro. whänui ratou iohere huaina aponeurosis. uaua Flat i kore anake nekeneke mahi, engari ano hoki i te tautoko me te tiaki.
4. Uaua atu ngā āhua: tapawha, porohita, pakihiwi, whai niho, trapezoidal, fusiform et al.

Ko te wehenga o nga uaua ki ngā rōpū i runga i te maha o nga upoko me te wāhi rānei

Hanganga me te whakarōpū o uaua tu'ati. Na, kua he torutoru upoko tetahi o ratou. E hoatu ana e ratou te ingoa i roto i runga i te maha o nga upoko: e rua-ahu (uarua), tengi (tengi), me ētahi atu

Ka rerekē i runga i te wāhi, nohoia nei e nga uaua i roto i te tinana, he pāpaku, me te hohonu, medial me lateral, waho, me te ā ratou.

Uaua i runga ki te pānga i runga i te hononga

Whakarōpū o uaua i roto i te pā ana ki te hononga titau odnosustavnyh (pā kotahi anake tahi) dvusustavnyh (mau puta noa rua hononga) me uaua polyarticular (mahi i runga i toru, neke atu rānei tahi).

Whakarōpū o nga mahi o uaua

E ai ki tenei paearu tohatoha uaua, synergistic me uaua enemi. Synergists arahi ki te kaupapa tahi i roto i te ahunga kotahi anake (flexors extensors ranei) me mahi te raveraa ra i runga i te tahi i roto i te rua ngā tohutohu ritenga (flexors me extensors).

Whakarōpū o nga mahi o uaua me ngā atu kōwhiringa. Kei te ārahi hoki uaua te abductor. Ka taea e te mahi mahi hurihuri ki te kōpeke, ki te whakawhāiti, whakawhānui, ara, raro, ki riaka, ki whakaroa.
