Chii chinonzi uropi hwomunhu? Kuti hukuru hwehuropi hunokanganisa sei kufunga

Uropi hwedu chinhu chinoshamisa. Inotungamirira mabasa ose anokosha emuviri, uye inokwanisawo kuona nekugadzira huwandu hwehuwandu hwemashoko. Chii chinokanganisa kuwanda kwouropi hwemunhu? Ndezvipi zviyero zvaro?

Kurema nekukura kwehuropi hwevanhu

Uropi ndeyomutambo wepamusoro wemagetsi. Inosanganisira zvikamu zvishanu uye yakafukidzwa nemabhomba matatu. Chikamu chemukati chinomiririrwa nemiti yakarurama uye yakasara hemispheres, iyo, zvakare, yakafukidzwa ne bark.

Zvechokwadi zviito zvedu zvose zvakagadziriswa nebasa reropi. Tinofunga, kuongorora, kufamba, kudya, kurara, kuvonga kwaari. Paanofa, tinofa zvakare. Uropi hunochengetedzwa zvakajeka muhenya redu kuderedza dambudziko rekukuvara.

Inokura uye inokura nesu. Pakuberekwa, kuyerwa kwake 300 gramu, uye nenguva iyi nhamba inowedzera kanenge kaviri. Iko yehuropi hwemazuva ano inosvika kusvika ku95% yehenya, iyo inotora mairi sezvainokura. Sezvo mutemo, uropi hunorema kubva pa1 kusvika pa2 kilogram, uye huwandu hwahwo mumunhu wepamusoro hunosvika 1200-1600 cubic centimita. Madzimai, hukuru hwayo hudiki kupfuura hwevarume.

Vanhu vekare

Zvisikwa zvokutanga zviviri zvine maronda zvakanga zviri Australopithecus. Mumaketani ekushanduka-shanduka, vakanga vari pedyo nemabhesi anthropoid, kusanganisira ukuru hwehuropi, iyo yakasvika mumavhumu asingadariki mazana matanhatu masendimita masendimita.

Makore anopfuura mamiriyoni maviri akapfuura, imwe yemiganhu yemajaya makuru (hominids) yakatanga kuchinja. Kunyanya, huropi hwavo hwakatanga kuwedzera. Masayendisiti anoratidza kuti izvi zvinokonzerwa nekuchinja kwehupenyu uye kushandiswa kwechigadzirwa chekutanga chebasa. Saka, ikozvino kune vanhu vekare kare yakanga yakakura kudarika iyo yemadzitateguru.

Vakatsiviwa nevanhu vekare - Neanderthals, uyezve Cro-Magnons. Zvakanakira kuti ivhu rehuropi hwevanhu vekare rakapfuura hukuru hwechimiro muvanhu vemazuva ano kusvika 20%. Chikonzero chechiitiko ichi hachisati chajekeswa.

Masayendisiti anoratidza kuti kuderedzwa kweuropi kunogona kutsanangurwa nemari yekuchengetedza. Chimwe chemashoko kwatiri mukufarira ndechokuvandudzwa kwekufungidzira kusinganzwisisiki. Achitenda kwaari, pfungwa dzakawanda dzakagamuchira zvinoreva zvizere, uye ruzivo rwakawanda "rwakasimbiswa" uye runotora nzvimbo shoma muuropi.

Iko ukuru hunoenderana nei?

Pane nharo yakajairika yokuti ivhu hwehuropi hwemunhu hunofungidzira pane mano ake ekufunga. Asi hupenyu hwezvinhu zvipenyu hwakanga hwakaoma kunzwisisa. Kuongororwa kwakasiyana-siyana kwave kuchiratidza izvi pfungwa kwenguva refu, zvichiratidza kuti izvo zvinokosha hazvirevi hukuru hwehuropi sezvinopindirana nechiyero chemuviri.

Chimwe chinhu chinonyanya kukosha uyewo chiyero cheuropi uye rwonzi rwomukona. Muvanhu i1:50. Kuenzanisa, mune kati chiratidzo ichi chinokwana 1: 1, mumonke - 1:16. Masayendisiti anogutsikana kuti ukuru hwehuropi hunovhiringidzwa nehutano hwemhizha dzakasiyana siyana. Iyo inobatanidzwawo nekuwedzera kana kuduku kusimbiswa kwemamwe mapurisa anoronga mabasa anoshanda mumuviri. Semuenzaniso, shiri dzine ruzivo rwakawedzerwa huropi, izvo zvinokonzera kuona uye kuenzanisa.

Kune humwe huripo huripo, zvakakwana kuva nehupfungwa hwakakura. Icho hachizokanganisa kubudirira kwepfungwa. Zvikuru zvikuru kana zviduku zvingave zvinoratidza kudarika. Iyo inocherechedza kuti uropi hwehutano hwemunhu ane autism hunogona kunge hwakangofanana nehuya hwakanaka, asi huchave husingafadzi uye husingaenzaniswi. Chirwere cheAlzheimer chinowedzera nokukurumidza kune vanhu vane uropi hudiki kudarika huwandu hwemazana.

Chokwadi chinofadza

• Maererano nekuongorora kwechangobva kuitika, huwandu hwehuropi hwakatemwa nokukurumidza nemanomwe ejeni.
• Pakati pevhesi, urefu hwacho hahupfuuri masendimita gumi nemashanu.
• Ukuru hwehupombwe hwevakadzi hwakaderera kune hwemurume nekuda kwezvikamu zvakaderedzwa izvo zvinokonzerwa nepfungwa. Kusiyana kunogona kusvika kusvika 150 gramu.
• Huwandu hukuru hunenge makore makumi maviri. Kukura kwakanyanya kunowanzoonekwa kubva kumakore manomwe kusvika ku11.
• Kuwanda kwe "thinker" yedu kunochinja nezera. Mucheche, inenge 300 gramu, muhukuru-kusvika pa2 kilogram, asi mushure me50 inorasikirwa nemagiramu makumi matatu nemakore gumi.
• Uropi hwepamusoro-soro emakumbo emhawi - sperm whale - inorema anenge makirogiramu manomwe, nzou ine 5.

• Pakati pevakadzi, chiremera chakakura zvikuru chaiva 1565 gm. Mune varume, yaiva 2850 gramu. Nhoroondo yakachengetedza yaiva murwere wepfungwa ne idiocy.
• Dinosaurs haina kudarika ukuru hwebhora nokuda kwepini-pong.
• Mumunyori wenhema Anatole France, uropi hwakayera 1017 g, Lenin's - 1340 g, Einstein's - 1230 g, uye Turgenev vakasvika muna 2012

Mhedziso

Uropi iko kakombiyuta duku inotungamirira zviito zvedu zvose. Iye ari pasi pekushanda zvakaoma uye mabasa. Mumarudzi akasiyana-siyana, zvepabonde zvakasiyana uye mapoka ezera, hukuru hwayo hwakasiyana. Saka, uropi hunokura patinenge tichikura, uye muhuchembera huri kuderera zvishoma nezvishoma.

Izwi rehuropi hwemunhu harina hukama hwakananga nehuchenjeri hwedu kana kuti zvisikwa. Mhuka dzakawanda, ukuru hweuropi hunopfuurira kupfuura munhu. Kuvandudza kwepfungwa uye kukwanisa kugadzirisa zvinetso zvakaoma kunotsanangurwa nehutano nekuvandudzwa kwezvikamu zvayo, uye kwete uropi huse.
