Minofu munthu: Kamangidwe. Mayina a minofu anthu

Thupi la munthu - dongosolo zodabwitsa kuti ndi amphamvu Kuvuta, ambiri nyumba yake opangidwa. Ngakhale izi, amachita n'zosadabwitsa bwino ndiponso molondola, efficiently kuchita ntchito. Movement wa thupi ikuchitika mothandizidwa ndi minofu, zomwe zili pafupifupi dera yake yonse. Kudzera ntchito yawo mosadzikonda, tingathe kuyenda, kupuma, kulankhula ndi kuchita zina, kotero bwino kwa ife zinthu.

mitundu ya minofu

Dzina minofu munthu anabwera kwa ife ku Roma wakale, amene okhalamo poyerekeza kayendedwe ka minofu minofu pa khungu la mbewa ndi legwork kwa pepala. Choncho, zosangalatsa, Aroma anatcha Latin mawu minofu musculus, omwe anamasuliridwa ngati mbewa. Kuyerekeza wakhala bwino kuti mawu awa ali lero. ntchito yake "pups" kupanga chifukwa luso kuotcha. minofu chigoba amagwira kwa periosteum wa tendons ndi, connective wosanjikiza wa khungu kapena minofu wina.

Tendons pomanga wa wandiweyani connective minofu. Iwo cholimba kwambiri ndipo akhoza kulimbana ndi kulemedwa kwambiri. Mu minofu minofu anayesedwa mitsempha imene amalandira chizindikiro kwa msana ziwiya chingwe ndi magazi, kupereka dongosolo lonse zovuta mafuta. Malinga kukonza kusiyanitsa minofu yosalala, striated ndi minofu mtima, kapena myocardium.

minofu yosalala

Mtundu uwu wa minofu minofu ndi zosaoneka ndi maso, monga minofu chigoba anthu. Galimoto ku Buku la mapu anatomical komanso popanda izo. Kuyambira yosalala minofu mpanda wa anatilenga ndi maliseche dzenje mkati monga chikhodzodzo, matumbo, m'mimba, ndi ziwalo zoberekera. Komanso, mtundu uwu wa minofu minofu ndipamene ziwiya zokwawa magazi ndi lymph.

Mosiyana ndi minofu chigoba osalala sali pansi chifuniro chathu. Izi zipangitsa ntchito mosadodometsedwa a dongosolo lofunika kwambiri la thupi, kuwasokoneza zomwe zingachititse kuti zotsatira zoipa. Yosalala minofu minofu ndi pulasitiki kwambiri - ndi bwino anatambasula ndi tingakhale yaitali mu mawonekedwe, popanda kutaya nkhawa. Mtundu wa minofu yafupika pang'onopang'ono, changwiro ntchito anaikidwa kuti izo.

Cross-striated minofu

minofu zimenenso wobvala mafupa athu amatchedwa striated. Izi kwambiri noticeable minofu anthu, malo awo zimathandiza thupi lathu kuchita lonse osiyanasiyana kayendedwe, kumene ife anazolowera. Unyinji wa minofu imeneyi ndi pafupifupi 40% ya misa okwana thupi amuna ndi 30% mu akazi. Aliyense minofu amamangiriridwa mafupa, kotero kuti pamene izo zikuchitika kuchepetsa kuyenda mu imodzi mwa malo. Kakonzedwe dera akufanana minofu anthu limagwirira kusuntha m'thupi dongosolo la levers ndi atilakwira.

Malinga ntchito, minofu kungakhale synergistic kapena ankatsutsa. Synergists ntchito limodzi pofuna kukwaniritsa ntchito, pamene muzikangana kuchita ntchito zosiyana. Ndiko kuti, pamene mapangano minofu, antagonist ake ayenera kumasuka kotero panali gulu. Chophweka njira kumvetsa mfundo imeneyi pa chitsanzo cha kukongola ndi triceps. Ngati mukufuna kuti pindani mkono wanu, kukongola ndiye mavuto, ndipo relaxes atatu mutu. Pakuti kutambasuka mikono chofunika njira zosiyana. Komabe, sikuti zonse zichitike, mwachitsanzo, kusunga kulemera pa dzanja lake m'mwamba, tiyenera kugwiritsa ntchito ndi kukongola ndi triceps. Pankhaniyi, iwo adzachita monga minofu-synergists.

minofu chidule si choncho nthawi zonse ndi mavuto. Ngati inu kusintha okha kutalika kwa minofu, ndiye mode iyi akutchedwa isotonic. Ngati pali minofu nkhawa, ndi kutalika kwake akanali yemweyo, ndiye katundu uyu akutchedwa isometric.

chidwi minofu ina - mtima. Osati kanthu ilo likutchedwa injini chachikulu cha thupi lathu. ntchito ake yothandizira zochita za anthu, kuthetsa lita imodzi ya magazi mkati. thupi tichipeza striated minofu minofu kuti, mosiyana ndi chigoba anasonkhana mu mitolo, m'madera ena zapiringizana ndi mzake. Kapangidwe Ichi chizathandiza mtima kutha mofulumira. Mosiyana ndi minofu chigoba myocardium samvera malamulo athu, ndipo ukugwira autonomously.

mantha dongosolo

Mkati aliyense msewu minofu Tambasula ya mitsempha ndi mitsempha ya magazi. Kumene, ndi ubongo ndi poyambira ya mitsempha mopupuluma, koma popanda chingwe msana silikanakhala kuthekera mwaluso bungwe minofu anthu. Chiwembu kayendedwe tsogolo aumbike mwa mkati mwa chingwe msana, kumene analamula chizindikiro akulowa minofu kuti. Chifukwa cha ichi minofu ntchito mogwirizana, monga mwambo mwendo, pali chopinga wa antagonist ake. Pa nthawi yomweyo, ngati n'koyenera, iwo akhoza onse akhale osangalala, ngati chizindikiro anakhumba ndi kwaiye.

Pamodzi ulusi mitsempha kupita maganizo kupyolera omwe ubongo amadziwa chikhalidwe cha minofu kuti. Sinthani dongosolo zovuta za manyuroni galimoto kuti kulandira chizindikiro mu njira ziwiri. Mmodzi wa iwo lakonzedwa kanthu amazindikira, ena - chifukwa reflex basi, monga kuyenda, kuthamanga kapena kupuma.

Magulu a minofu anthu

minofu akhoza kugawidwa m'magulu osiyana, omwe ali mbali yake. Dera dongosolo la minofu ya munthu kumafuna magawano awo makonzedwe mu:

• Quadriceps.

• Atatu mutu.

• Ng'ombe.

• Trapezoid.

• minofu m'mimba.

• Patsogolo.

• Minofu ya mapewa.

• Back minofu.

• Flexors manja.

• Extensors manja.

• Thako.

• Adductors.

• Dzanja flexors.

• Extensor carpi.

• Catchers masamba.

• Sciatic-tibial minofu.

• Lumbar.

Magulu amenewa akuphatikizapo anthu minofu zofunika, zomwe dongosolo mwina tikuonera magulu awa.

Minofu ndi munthu

Ntchito ya minofu ndi zofunika kwambiri pa thanzi, kuwasungira mawonekedwe abwino - chinsinsi yaitali ndi mphamvu ya moyo. Mwatsoka, anthu ambiri kudziwa za izo, mwachangu tikambirane zimene masewera mu mapangidwe thanzi labwino, koma iwo akupitirizabe kukhala moyo wongokhala. Choncho magulu lonse minofu anthu kukhala makuponi. moyo wongokhala amachititsa manja minofu minofu, matenda a dongosolo mtima. Effeminate mtima sangakhoze kulekerera katundu ngakhale ang'onoang'ono, komanso kuwala, kumene kumakhala amachepetsa voliyumu. Kumbukirani, inu simungakhoze kukhala ndi thanzi labwino ngati minofu wanu amakhala wofooka. Apatseni ntchito - ndi sikuti kudikira nthawi yaitali.
