The nemamiriro muzongoza

Vanhu vazhinji kurerutsa kukosha marangwanda, zvikurukuru nomuzongoza. Zvisinei, kuita zvakadaro kufanira, nokuti anobatsira basa rinokosha muupenyu hwevanhu. Kuti anotsigira munhu akarurama ezvinhu, mukuwedzera, rinoshanda se kutsigira kuti tsandanyama dzomuviri uye zvomukati, anoumba rusvingo thoracal uye abdominal in. kuti musana mamiriro anobvumira kuti kukurira zvikuru mitoro, nepo anoramba kwayo mukana wokushandiswa uye kufamba. Kazhinji, paunotanga kufungisisa pamusoro mudziyo kana muviri kuti, kunyanya musana, mumwe nguva munhu akarova nouchenjeri hwezvisikwa.

Spine zano vose, nyore uye tsanzira yazvo nenzira. Inoitwa 32 vertebrae, uye pamusoro marongerwo uye chinangwa chacho rakakamurwa 4 zvikamu: sacral, lumbar, thoracal uye remuromo. Mumwe STRUCTURAL zviri dzakasiyana zvikamu nomuzongoza ndechokuti dhipatimendi rimwe nerimwe rine vachikotama ayo mberi kana shure. vakafugama mirayiridzo rakatumbuka vaviri vaviri vakanga remuromo nomuzongoza akatsunga mberi makakombama dzakadaro dzinonzi lordosis, thoracal - kare, kwakadaro vanobwembura inonzi kyphosis, uye zvichingodaro. mamiriro kwakadaro kunoita kuti musana kutsungirira zvikuru mitoro, nokuti zvakafanana chitubu, iyo anoita se nehana absorb, cushioning mutoro panguva achifamba uye kumhanya.

Mumwe vertebra, kunze kwokutanga remuromo, asi zvakawanda pamusoro paikoko, rine muviri uye chinhu chakakombama. The chinhu chakakombama rinotsanangura pakazaruka imwe vertebra. Pamwechete makomba aya ndeakaita mhango mukati vertebral mbiru iyo, pasi rinorema murindi mapfupa ndiye ari musana. Uyezve, mumwe vertebra ane Paarismängud uye Paarismängud shoma. Ivo, pamwe chete intervertebral discs nemarunda, anopa batira pakati vertebrae.

Ikozvino ngatitaurei pamusoro mumwe wedhipatimendi nomumwe. Unofanira kutanga Chokwadi, pamwe pamutsipa. Rinosanganisira zvose 7 vertebrae. Kukura pakati remuromo vertebrae iduku zvikuru pane vamwe vose. Kazhinji, kukura vertebrae kunowedzera pedyo coccyx. Izvi zvakakodzera kudzikamisa kuwedzera mutoro.

Asi shure remuromo vertebrae. Ndinofanira kutaura kuti nechivako yavo ndiyo siyana. Most zvakasimba hwakasiyana nemamwe pakutanga vertebra, inonzi atirasi. Haana kuva muviri, rinoumbwa arcs uye muitiro. Wechipiri ane muviri, asiwo yakasiyana nedzimwe remuromo vertebrae pedyo kwacho guru, anotaurwa so zino. Izvi ndizvo akabatana pakavakirwa musoro iri kugadzira. On kumativi remuromo vertebrae anogona kuonekwa vestigial zenze spines. Vazhinji vose vari anotaurwa 6 vertebra. An buri akaumba panguva arc iri remuromo vertebrae ane mativi chimiro.

Thoracal vertebrae dhipatimendi vane muviri saizi kukuru, chimiro mumakomba dzinoshandurwa kuti raundi pamusoro transverse muitiro womunhu vertebrae thoracal dhipatimendi ane maburi rumbabvu.

Tinoramba kutarira nemamiriro nomuzongoza. Next Front - lumbar. Paiva neimwe kuwedzera kukura mumutumbi vertebrae. Uyezve, mashoko lumbar vertebrae zvisingapindirani pane chinjikira urongwa ayo kwendangariro. Hole saizi zvakati duku.

Vertebrae sacral dhipatimendi akaparadzanisa kumusoro chete makore 25 okuberekwa, pakazosvika nguva vanokura pamwechete. The zvichiguma pfupa inonzi sacrum uye ane mativi chimiro. Ndizvo chikamu chiuno.

Lumbosacral nomuzongoza rakasiyana nevamwe hombe kukura vertebrae. Handiti, izvi chikonzero kupfuura mugove mutoro.

Tichitarisa nemamiriro nomuzongoza, handigoni kuona intervertebral discs. Yavanobata dzakawanda mabasa: unobva vertebrae nomumwe uye kupa mufambo yacho nomuzongoza. pakawanda kwakadaro kunoitwa kuburikidza rakasiyana nemamwe mamiriro. The dhisiki ine zvikamu zviviri: panozogadzirika, iyo iri pahwaro shwashwa hwakasimba uye gobvu connective chindori tishu. Shwashwa achipfeka kumboenda mutoro, uye mhete akaripoteredza compensates izvozvo.

Kazhinji mashoko, kuti musana mamiriro vanofanira kare kuva pachena. Chokwadi, pane vazhinji mashoko maduku uye features, asi imwe nyaya pachena zvose chete hakuna kukwana.
