Kapangidwe ka msana

Anthu ambiri amanyalanyaza kufunika kwa mafupa, makamaka msana. Komabe, kutero sikuthandiza, chifukwa kumathandiza kwambiri pa moyo wa munthu. Kuti amathandiza munthu mu chikhalidwe molungama, kuwonjezera, umakhala kuthandiza zimakhala minofu ndi ziwalo, ndipamene mpanda wa cavities thoracic ndi m'mimba. kapangidwe msana chololera kupirira katundu yaikulu, pamene akuzisunga kusinthasintha ake ndi kuyenda. Nthawi zambiri, pamene muyamba kuganizira chipangizo kapena thupi, makamaka msana, nthawi iliyonse munthu chidwi ndi nzeru za chilengedwe.

Msana chiwembu chonsecho, yosavuta ndi luso mu njira yake. Amakhala 32 vertebrae, ndi pa kapangidwe ndi cholinga kuti lagawidwa m'magawo 4: sacral, lumbar, thoracic ndi khomo lachiberekero. Imodzi mwa mbali structural wa osiyana mbali msana ndi kuti aliyense dipatimenti ali kupinda wake patsogolo kapena kumbuyo. kupinda malangizo alternating awiriawiri: msana khomo lachiberekero akuyesetsa patsogolo zokhotakhota amenewa amatchedwa lordosis, thoracic - zapitazo, monga unakhota amatchedwa kyphosis, ndi zina zotero. Chotero eg amalola msana kupirira katundu yaikulu, chifukwa ndi ofanana ndi masika, yomwe imateteza absorber mantha, cushioning katundu pa kuyenda ndi akuthamanga.

Aliyense linkawonongeka, kupatulapo khomo lachiberekero choyamba, koma zambiri kuti pambuyo pake, imakhala ndi thupi ndi Arc. Arc imalongosola otsegula mu linkawonongeka a. Pamodzi mabowo awa amaonetsera ndi M'mimbamo mwa ndime vertebral amene, pansi zolemera alonda fupa la msana. Komanso, aliyense linkawonongeka ali awiriawiri ochepa ndi awiriawiri. Iwo, pamodzi ndi zimbale intervertebral ndi Mitsemphayi, kupereka zowalamulira pakati vertebrae lapansi.

Tsopano tiyeni tikambirane za aliyense dipatimenti payekha. Muyenera kuyamba, ndithudi, ndi khosi. Pamafunikanso onse vertebrae 7. Miyeso ya ku vertebrae khomo lachiberekero n'chochepa kwambiri kuposa ena onse. Nthawi zambiri, kukula kwa vertebrae ndi kumawonjezera kwambiri kuti coccyx lapansi. Izi ndi zofunika zoperewerazo katundu kuwonjezeka.

Koma kubwerera ku vertebrae khomo lachiberekero. Ine ndiyenera kunena kuti dongosolo awo ndi osiyanasiyana ambiri. Ambiri kwambiri isiyana ndi zina linkawonongeka koyamba, wotchedwa Buku la mapu. Iye analibe thupi, wapangidwa ndi arcs ndi njira. Lachiwiri ndi thupi, koma isiyana ndi zina vertebrae khomo lachiberekero ndi ndondomeko zikuluzikulu, amatchedwa dzino. Zimenezi ndi olamulira padziko lomwe mutu sangathenso. Pa mbali ya vertebrae khomo lachiberekero Tingaone vestigial chipsyepsye spines. Koposa zonse iwo m'kukoma 6 linkawonongeka. Otsegula anapanga pa Arc wa vertebrae khomo lachiberekero ali ndi mawonekedwe triangular.

Thoracic vertebrae dipatimenti ndi wamkulu thupi kukula, mawonekedwe a m'maenje ndi unasintha zozungulira pa ndondomeko yopingasa wa vertebrae thoracic dipatimenti ali nthiti mabowo.

Tiyenera kupitiriza kuyang'ana pa dongosolo la msana. Kenako Front - lumbar. Panali kuwonjezeka wina mu kukula kwa thupi la vertebrae lapansi. Komanso, ndi lumbar vertebrae amasiyana dongosolo yopingasa njira zake. kukula dzenje ang'onoang'ono kwambiri.

Vertebrae sacral dipatimenti anapambulwa mpaka okha azaka 25, pa nthawi imene iwo zikulire pamodzi. Fupa chifukwa amatchedwa sacrum ndipo ali ndi mawonekedwe triangular. Ndi gawo la mafupa a chiuno ndi.

Lumbosacral msana ndi wosiyana ndi ena onse kukula ikuluikulu ya vertebrae lapansi. Pajatu chifukwa cha gawo lalikulu kwambiri katundu.

Poganizira kapangidwe ka msana, sungakhoze basi asataye zimbale intervertebral. Iwo amagwira ntchito zingapo: kulumikiza vertebrae wina ndi mzake ndi kupereka sayenda msana. amagwiritsidwa ntchito mwanjira amenewa Zimapezeka ndi dongosolo lapadera. litayamba imakhala ndi mbali ziwiri: a pachimake, ozikidwa pa chichereŵechereŵe olimba ndi wandiweyani connective mphete minofu yowonongeka. Chichereŵechereŵe adzatenge katundu pamoyo, ndipo mphete yozungulira compensates izo.

Mu mau, kapangidwe msana ayenera kale bwino. Kumene, pali chiwerengero chachikulu cha zinthu zazing'ono ndi zinthu, koma nkhani ina kuulula zonse chabe si kokwanira.
