Sei dehenya musono nezera?

Human dehenya harisi chete chinonyanya kukosha mapfupa inotungamirwa, asi ndiyewo nemaziso vakakurumbira. Naizvozvo, kusiyana kwayo zvose hazvigoni kunooneka. Zvokukura kushandurwa zvikuru hama uye mumwe munhu akasiyana nevamwe, asi pane mirayiridzo mukuru kwakavakirwa zera.

Mumakore upenyu hwevanhu yeDehenya iri pachena kuti dzakasiyana-siyana kuchinja. Hazvina hanya zvikurukuru chitarisiko chake. Conventionally, pane nguva huru shanu yokuchinja. Ngatikurukurei chimwe nechimwe chezvinhu izvi zvizere.

yokutanga nguva

Nguva iyi ndiyo vanoshingaira kunenge kuchiita musoro uye kunotora okutanga makore manomwe upenyu. Kubva pakuzvarwa mwedzi mitanhatu, nekaviri vhoriyamu neurocranium. By makore maviri, vhoriyamu dzayo nekatatu, uye makore mashanu ari-mumativi matatu yose dehenya. reshiyo iyi vakaramba kuti upenyu. Zvaive munguva iyi ndiyo zvikuru kudzika cranial fossa, uye seri musoro anotanga kutaura. Uyezve, mashoko membranous zvinyama zviri cranial rakatenderera uye cartilaginous zvinyama ari occipital pfupa mutate uye zvishoma nezvishoma kunyangarika. It kunoitika yokutanga (danho rokutanga) rokuumba kuti marangwanda musoro musono. Nguva iyi ndiyo zvikuru, nokuti dehenya musono hakusi nyore hwokuchengetedza mapfupa musoro pamwe mumwe uye, zvakakosha, ndiyo nzvimbo kukura kwavo upamhi.

Kupatsanura pakati cranial sutures

Sutures dzinoiswa maererano chimiro zvinotevera:

• toothed;
• scaly;
• pamhama.

Toothed dehenya musono inoumbwa vaviri pfupa hukawanika kana munhu ane maberere, uye pane dzimwe - notch ichizadza pamaberere izvi. Izvi mhando mapfundo ndiyo yakasimba. By nemisoro miviri yehombodo mapfupa pedyo flake kuumbwa dehenya suture. vazvo vose vakazadzwa connective zvinyama kuti anopa simba uye kufamba pamusoro yeimwe yakadaro. Uye wechitatu mhando welds - sandarara. Flat dehenya suture kuumbwa vaaisangana zvishoma Wavy kana zvachose sandara pfupa hukawanika. With kwakadai musono kubatana kunoitika mapfupa chiso pakati pavo, uye zita ravo kunobva interconnected mapfupa inotungamirwa.

Chechipiri nguva Kuchinja

Mumakore mashanu akatevera, mapfupa musoro varikukura zvikuru zvishoma nezvishoma. It kunoitika zvakawanda nemaziso kuoneka Kuchinja kukura uye chimiro pamberi chikamu dehenya (the muchadenga, iyo nasal mhango uye maxillary). Kuvharwa kunyange iri neonatal munguva fontanelles inonyangarika zvachose, uye mapfundo azara connective Tacna.

wechitatu kumwedzi

Nguva iyi rinobatana pakuyaruka munhu uye kunotora makore gumi (range makore 14-15 pazera makore 25). Inouya yokupedzisira dehenya kukura uye zvose zviri axial marangwanda. In iyi youpenyu (kusiyana yapfuura maviri) zvakawanda ndichibvunza ikure rune dehenya, pane chepfungwa. The suture yeDehenya sezvo anatomical inotungamirwa hunowedzera rakasimba, uye anotanga nguva Ossificação em, huchavapo ndakwegura. Kuwedzera mujinga dehenya kumativi ose, kwete chete paupamhi. Pakupedzisira kuumbwa grooves, anooneka zvikuru nemichinjiziri, anorovera uye pneumatic sinuses.

Wechina kumwedzi

Kubva makore 25 uye kusvika 45 hapana shanduko mapfupa musoro kukura. Panguva iyi, dehenya musono ossified. Mune zvisingawanzoitiki chaizvo zvinoitika, zvipfundo anogona kuramba muupenyu.

The wechishanu kumwedzi

Danho iri rinotora kwenguva imperforate musono kusvikira mukukwegura. It kunoitika pamwero mukuru anatomical kuchinja, uye STRUCTURAL. Nemaziso achinja chiso dehenya yakafanira mavende uye atrophy pakati ari alveolar kwendangariro. With zera, pakukora ipfupi cancellous uye chiine ndiro uye dehenya kunova nyore. Nokuda pfupa resorption uye mapfupa chicherwa achinje mamiriro ayo anova pfava, mutswe uye zororo.

mhedziso

Human dehenya - anonzi marangwanda musoro. Chimiro anatomical kunokosha zvikuru kwete chete kudzivirira uropi uye kutsinga dzinouya zvomukati. Rinoumba chitarisiko chedu (chiso).

The musono yeDehenya, sezvo chivakwa-yaishandiswa chikwata inoita basa rinokosha unobva dehenya mapfupa pamwe chete. In vana, navarairi vazvo vane zvikuru mukana wokushandiswa, asi nezera ivo ossify.

Zvokukura Kugadzirwa dehenya mapfupa vane zera nemiganhu. Nokudaro, neonatal nguva, kunyange kana mumabhatiri fontanels (membranous Danho), munhu shwashwa kuibvisa unobuda tichifambirana, uye ipapo kupinda mafupa.

Pakazosvika nguva yokuzvarwa haina rakapera uye paumbwe dehenya. Pane matanho mashanu ayo kukura. Saka, kubvira pakuzvarwa kusvika kuchikoro zera (makore 6-7) kuti dehenya inokura kunyanya kureba, anotevera mashanu makore manomwe ndiwo nekarunyararo akadzikama, uye kutanga kuyaruka uye kusvika makore 25 okuberekwa kuitika okunatsiridza kunyanya ayo nechemberi.
