Dongosolo chigoba ndi magulu akuluakulu minofu

dongosolo akulu amatanthauza munthu wa subsystems zofunika kwambiri kwachilengedwenso imene thupi amachita izikhala.

Iwo akhoza ankayimiridwa ngati ya ulusi minofu angathe chidule. ulusi amalowana mukulumikizidwa pamodzi mitolo, zomwe ndi minofu monga matupi wapadera kapena okha kulowa ziwalo. Minofu misa ndi apamwamba kuposa wa matupi ena: ena nyama ndi 50 peresenti ya kulemera kwa thupi, ndi munthu - 40 peresenti. dongosolo akulu otembenuka mphamvu mankhwala mu kutentha ndi mphamvu mawotchi.

akulu musculature

Mu inakhala, akulu musculature ali m'magulu awa:

• Somatic, lili mkati ndi kupanga minofu ya nthambi. Izi zikuphatikizapo minofu chigoba.
• Choipidwa (mbali ya viscera wa). Ndi yosalala ndi mtima minofu.

Dongosolo akulu wa munthu

minofu chigoba ali striated ndi umasinthasintha. Iwo amagwira mafupa ndi cylindrical ndi CHIKWANGWANI kutalika 1-10 cm.

Aliyense minofu CHIKWANGWANI - ndi undifferentiated cytoplasm (sarcoplasm) ndi mitima kwambiri anakonza pa periphery wa. The periphery zikuphatikizapo kusiyanitsidwa striated myofibrils. Iwo lozungulira periphery wa m'chimake mandala (sarcolemma), chomwe kolajeni fibrils. Kagulu ka ulusi wazunguliridwa endomysium; minofu mankhwala lalikulu ndi mitolo ya ulusi, kupangidwa mwa peremizy mkati; lililonse minofu atazungulira peremiziem akunja. Minofu minofu connective akupitiriza mzake ndi inakula. Minofu lonse la- mu m'chimake otchedwa fascia. dongosolo chigoba zikuphatikizapo minofu, omwe chikugwirizana kwa mitsempha ndi mitsempha ndipo atagonjetsa iwo.

Minofu adzithandiza muyezo wa thupi, kuti agwire gulu danga ndi kayendedwe zofunika zigawo zonse thupi.

minofu yosalala zili Mitsempha ndi ziwalo. Kutalika kwa mtundu uwu wa minofu ndi 0.02-0.2 mm. Iwo mosatsata striation, mawonekedwe awo akufanana ndi spindle. maselo yosalala minofu ndi chowulungika pakati pakati.

minofu yosalala kuthandiza zoyendera kuti ali ziwalo dzenje (chakudya mu matumbo, mwachitsanzo). Iwo nawo lamulo zoipazi, patsogolo ndi chidule cha mwana wa, kayendedwe zina za thupi. Pakuti yosalala minofu udindo mantha dongosolo autonomic.

dongosolo minofu ndi mafupa zikuphatikizapo minofu mtima, yomwe imapezeka mu khoma mtima. Iye mosalekeza yafupika moyo, kupereka magazi kudzera ziwiya ndi chakudya zinthu zimakhala zofunika ndi ziwalo.

Musculo-chigoba dongosolo

Thupi la munthu lili 400 minofu striated, amene yafupika pansi pa ulamuliro wa chapakati mantha dongosolo.

Musculo-chigoba dongosolo zikuphatikizapo minofu, mafupa, tendons, mafupa, Mitsemphayi ndi chichereŵechereŵe amene amapanga pafupifupi 75% ya kulemera kwa thupi. dongosolo lino amapereka thupi mawonekedwe ena, lilili kuima ndi kuyenda. Mafupa kwa ziwalo ndipo zimakhala akutumikira monga mafupa, komanso amateteza ziwalo zofunika zisaonongeke. Mafupa kudziunjikira mchere monga phosphorous ndi calcium. Mkati mwa fupa ukufanizidwa ndi m'mafupa, nawo mapangidwe maselo magazi (maselo ofiira, maselo oyera ndi maselo othandiza magazi kuundana).

Pamene kuvulala ndi matenda a mbali ina ya dongosolo minofu ndi mafupa ndi kutanganidwa statics ndi mphamvu ya lake lonse. Komanso, amavutika ndi lonse minofu ndi mafupa dongosolo, ziwalo, nayenso, tisiye liziyenda bwino. Mwachitsanzo, ndi zowononga munthu wa miyendo ndi yokhota kumapeto msana, zomwe zimabweretsa mapindikidwe a chifuwa, monga Motero - amadwala ziwalo magazi ndi kupuma.
