How mapfupa zhinji vari muviri womunhu zvose

Vanhu vazhinji vanofarira pamafupa vangani mumuviri womunhu. Ngatiedzei kupindura mubvunzo uyu.

Zvetsandanyama nemapfupa maitiro womunhu ine kwete chete kubva marangwanda, asiwo kubva netsandanyama. Uchibatsirwa zvayo munhu anoita kufamba siyana, uye achiri rinoshanda kudzivirira zvomukati kubva mukukuvara siyana. Chimiro muviri womunhu pakutsvaga marangwanda. Mapfupa mumuviri pane vanenge 210.

The marangwanda yevanhu mhando dzakawanda mapfupa. Ndinoda kutarisa zvakadzama panguva mapfupa vangani mumuviri womunhu, uye zvavari. Kune marudzi anotevera pavo:

1. mapfupa Long: yacho humerus, rokumusoro ruoko, chidya uye mhuru.

2. Short: mapfupa tsoka uye ruoko.

3. Flat: mapfupa dehenya uye bandauko mashizha.

Bone pamusoro akafuka gobvu goko, yainzi periosteum. It kunoitika nokuda kukura mapfupa, zvokudya zvavo, uye Fusion mu mitswe. Nokuda periosteum mapfupa vachikura pahupamhi uye urefu, hairuki tichiregeredza kugovera shwashwa masero, izvo riri pakati mapfupa muviri wayo kumugumo.

Yose, vanoumba marangwanda yeDehenya, apa ari okumusoro migumo uye hunde.

Ngatikurukurei kuti mapfupa mazhinji muviri iri mu nerimwe zvinoriumba. The dehenya kuchibva chiso uye pfungwa zvikamu. Rinoreva muuropi dhipatimendi dehenya, iyo inoshanda kudzivirira uropi mukukuvara siyana. Muuropi dhipatimendi zvinosanganisira: frontal, occipital, parietal, uye 2 2 mapfupa nezvepanyama. Nokuti chiso nharaunda dzakasiyana-siyana zviduku mapfupa (nasal uye zygomatic mapfupa, okumusoro shaya). Vachiri zvakabatana mumwe, kunze rezasi shaya.

Zvino funga kuti mapfupa zhinji mumuviri womunhu rinoreva muviri marangwanda. Its fomu racho nomuzongoza uye thorax. The maumbirwo rine musimboti 4-5 coccygeal, 5 sacral uye lumbar, 12 thoracal, 7 remuromo vertebrae. Somugumisiro, mashoko nomuzongoza rakakamurwa 5 zvikamu dzine zita dzakafanana vertebrae, ayo aisanganisira.

Thorax, iyo inoshanda se kudzivirira mwoyo nemapapu muchiwirirana rinoumbwa mbabvu 12 uye sternum.

Sechivako yokumusoro gumbo rine mumapoka matatu: ruoko, honokono uye nepfudzi. Bandauko chakaumbwa yakareba yokumusoro ruoko, honokono - the ulna uye nharaunda, uye mumakwenzi rinoumbwa mapfupa duku. Maoko vari vasiyana mumuviri pachishandiswa bondo uye mashizha kuti zvinoumba bandauko bhandi.

Mbabvu Lower zvinosanganisira tsoka, yakaderera gumbo uye pahudyu. Nebandauko kuchibva femur, inova kupfuura mumuviri wose. Shins - kubva 2 tibia uye rutsoka muri vashoma mapfupa diki, remasangano unova chitsitsinho. Mbabvu Lower vari vasiyana muviri nokuda mapfupa pelvic.

Pasinei munyaya data, iwe uchiri havagoni kutaura chokwadi zvingani mapfupa ari munhu marangwanda. Somuenzaniso, achangoberekwa ane zvakawanda kupfuura vakuru, nokuti mukati guru srostayutsya mapfupa duku atova nedanho kukura mwana.

Saka, chaizvo nhamba inoratidza mapfupa vangani mumuviri womunhu, no. Mumwe anotaura dimikira 200, vamwe 220.
