Te roro tangata: hanganga

whakarato ruruku me te mana o ngā mahi tinana katoa e he nui mo te mahi noa te roro tangata, a ka mana ano whanonga. Hiahia, whakaaro, mana'o - hono katoa e ki te roro. Ki te te kore mahi tenei tinana, riro te tangata i te "tipu."

Te roro tangata: kiripuaki

Brain - hanganga hangarite, Heoi, rite maha atu whēkau. taimaha i whanau roro ko e pā ana ki toru rau karamu, i roto i te paariraa e ata reira kirokaramu kotahi me te hawhe. Whakaaro i te hanganga o te roro tangata, ka taea e tatou te kite tonu e rua tuakoi e kua huna i raro i te hanganga hohonu. hipoki Hemispheric convolutions moku,, fakalahi te medulla waho. Muri - te roro tuarongo, te raro - te kātua, e haere ki te ua. A i te kātua, me i te filosilivá raru ko aho manga i roto i, he reira hoki ia i te mōhiohio i te mau farii ohipa ki te roro e heke, he reira hoki ratou e tuku i te roro tangata tohu ki nga uaua me repe.

I roto i te roro kua he taonga ma whakatu muka io e hono wāhanga rerekē o te tinana, me te hanga i waenganui i a ratou ano raru whakawhānui ki ētahi atu whekau, me te taonga hina hanga i te uho kaka me ngā matua o te tinana karere pūtau. tiakina te roro tangata e te angaanga - take wheua. Matū e wātea ana i roto i te okana, me te wheua taiepa wehea e toru anga: te totoka (waho), ngohengohe (roto), me te pai arachnoid. ki tonu te wāhi hua i waenganui i te anga e ki te hanganga rite ki te toto wē, CSF (cerebrospinal) wai. whakaputaina te reira i te tino inu i roto i nga ventricles o te roro - te kōwhao roto reira, tona tūranga - ki te homai i te roro tangata ki ngā matūkai faufaa.

whakarato i te pera kakī te tohanga kaka, kua wehea ratou i te raro i roto i manga nui e whakawhānui ki rohe rerekē o te roro. Koinei, te roro tonu e tango 20 ōrau o te toto komuhumuhu i roto i te tinana, ahakoa ko te taimaha o te katoa taimaha o te tangata okana 2.5 anake ōrau. Fakataha ki te toto ki te roro tukua ki te hāora, te whakarato ratou tino nui, pera ake rāhui pūngao o te tinana, he tino iti.

pūtau Brain

O ngā pūtau, ka karanga neurons, ko reira te pūnaha io pokapū. Ko ratou kawenga mō te tukatuka mōhiohio. Kei roto i te roro tangata i 5 ki te 20 piriona neurons. Haunga a ratou, te whakaatu i te okana pūtau glial, i te mea e pā ana ki 10 ngā wā nui atu neurons. pūtau Glial te hanga i te kōhiwi o te karere kiko, me te whakaki i te wāhi i waenganui i neurons. Ka rite ki tetahi atu pūtau, neurons e karapotia e te membrane wē. O ngā pūtau whakawhānui tukanga - axons (tino maha i roto i te kotahi roa axon pūtau kotahi i o henimita te tokorua ki te maha mita) me dendrites (ia neuron maha dendrites, branched ratou me te poto).

Te roro tangata: tari

Conventionally, kua wehea te roro ki ngā wāhanga e toru: te roro mua, kakau, roro tuarongo. Kei te wehea te forebrain ki e rua tuakoi, thalamus (karihi rongo e tango mōhiohio i whēkau, me te whakawhitihia reira ki te uho tairongo) me hypothalamus (rohe whakahaere mahi homeostatic), rapae o - repe nui. Tuakoi - te wahi nui o te roro tuatihia te tahua io hono - axons kurupae. He nga matamata kōpako, kōpako, pae tino, me te frontal ia tuakoi. Ko te kātua ngā te oblongata medulla (te wahi o raro o te kātua, e haere ki te ua), te Pons (e pā ana ki te muka roro tuarongo io) me midbrain (i roto i ki te ua he nekeneke ara). Kei te roro tuarongo i raro i te matamata kōpako o nga tuakoi o te roro, whakahaere i te reira i te tūranga o te kātua, wahi, upoko, whai wāhi nui i roto i te whakaputa pūkenga nekeneke.
