Kuti tiite zvose zvemarudzi kufamba ari mumuviri womunhu, pane tsandanyama kuti zvinogona kukamurwa marudzi mikuru mitatu. Ava: skeletal, cardiac kumeso. Mumwe ane pachake chinangwa chacho uye zvakasiyana marongerwo.

Kugadzwa tsandanyama mumuviri womunhu

chinangwa wokutanga uye chikuru muviri kutsigira mapfupa uye nhengo dzomukati. Tsandanyama chose kufukidza womunhu muviri uye kutakura chikuru chinangwa - kutsigira uye kugadzira motokari mabasa. Mumwe nomumwe muviri wedu kufamba kunopa tsandanyama rinenge uye hazvisi chete kufamba maoko nemakumbo, asi achibwaira, kumedza, kubudiswa uye kufamba zvokudya, mwoyo. Pasina tsandanyama rinenge kwevanhu muviri haagoni kushanda.

Nemamiriro tsandanyama hurongwa

All tsandanyama munhu anogona mapoka mapoka maererano nechinangwa uye nzvimbo.

Zviri nyore zvikuru kuti kuvabata mapoka makuru, somuenzaniso, kupatsanura vave vatatu. Saka, kuti tsandanyama ari mutumbi zvinosanganisira:

• shure;
• zamu;
• abdominal.

Pakazosvika dorsal hunde tsandanyama vari asingafungi uye rakadzika.

Zvachero tsandanyama of shure

Zvachero tsandanyama vanomirirwa:

• Trapezius tsandanyama, zvakabatanidzwa zvose thoracal vertebrae uye kuguma kwayo yechipiri kuna clavicular pfupa uye scapular musana uye ndiye anokonzera flexing musoro. Hazvina mhosva kwebasa mashizha. Yokumusoro chikamu zvinomutsa, uye ezasi pasi. Kana kutapa maoko kare, avhareji yacho tsandanyama kunoderedza chipande pedyo nomuzongoza. Also vasiyana mujinga yeDehenya uye mutsipa.
• Latissimus dorsi akatevera trapezoidal vasiyana vamwe musana uye nechepasi mugove pamberi pechipfuva vertebrae, saka akafukidza zvose zvakakwana chimurenga muviri. Hazvina chete corset kuti muviri, asi chinokwezva pamapendekete uye maoko shure apo achivatsausa mukati. Iye ndomumwe wevaya vari boka "tsandanyama guru", sezvazvakaita rimwe remasangano ari muviri wose.
• Rhomboid tsandanyama, zvikuru nezviduku, nhema pasi trapezius uye matanda aro vari vasiyana rezasi remuromo vertebrae uye ukabata 4 thoracal, uye mumwe mugumo vasiyana scapula pfupa uye mhosva zvayo nzira pakati.

• Levator scapulae tsandanyama, zviri zvishoma yakakwirira pamusoro nedhaimani serin'i seri kwemitsipa. Mumwe magumo wanamatira maviri remuromo vertebrae uye vaviri thoracal vertebrae, uye chikamu chayo chechipiri wakaiswa pamusoro mucheto. Ichi wokuisira chakanaka pamutsipa, nokusimudza mashizha kumusoro.
• Rezasi uye yokumusoro shure toothed tsandanyama. Lower obliquely iri shure uye kunotangira lumbar, richengetwe kusvikira mana pasi kumicheto vokutanga. Ndiye anokonzera achideredza pamusoro mbabvu. The pamusoro ndiyo nedhaimani serin'i uye wanamatira pamusoro kumucheto, kutangira kubva 2nd kusvika 5, pane dzimwe mugumo wayo akabata pamusoro ari remuromo vertebrae. Anokonzera yokumutsa mbabvu.

Deep tsandanyama of shure

Pakazosvika mutumbi tsandanyama vari zvakare lateral kuti medial, izvo riri mativi ose nomuzongoza mbiru Munotatamura kubva sacrum uye occiput. Lateral nebasa kuswatura musana uye asingafungi. Medial tsandanyama dziri nechepasi hama kuna mamwe uye panofanira mapoka maduku tsandanyama mwanda raiberekwa muzongoza yake. Uyewo kune tsandanyama idzodzo bhandi tsandanyama musoro uye mutsipa, nokuita zvose kufamba uye rudzi corset.

Izvi zvakakodzera nokuti kwebasa ruoko pamusoro chinjikira nzvimbo. Uyewo, zviri pamwe chete rhomboid tsandanyama, runonditsikirira chipande pedyo muviri wako.

kufema tsandanyama

Pakazosvika mutumbi tsandanyama dzinoitawo kufema. External uye munyika intercostal tsandanyama dziri pakati mbabvu uye anokosha mipiro panguva inhalation uye nedzinovengwa.

Aperture - kupfuura kujairika urongwa flat tsandanyama kuti ane ainge akamonererwa kuita raundi chitarisiko. It anokanda convex divi kumusoro. By kwayo chiito iri pisitoni pombi, nokuti kufema ushande. Hazvina tsandanyama ichi anorumanya uye decompresses mumapapu, zvichiita kuti kuzadza ne mhepo uye anosunungura pake. The diaphragm wanamatira kumativi mukomberedzo pechipfuva. Iye akatambanudza pamusoro mbabvu, musana, rezasi chikamu pachipfuva.
