Mhedziso

Tsinga dzetsinga dzinoumbwa nezvikamu zviviri. Chikamu chimwe nechimwe chine mabhiriyoni emauroni. Chikamu chekutanga ndiyo yepakati tsinga system. Ine huropi uye musana, inova tambo, yakaita senge tambo inomhanya nepakati pesipinha pasi nepakati pemusana.

Icho chimwe chikamu chikamu chekumusoro chetsinga. Inoumbwa nezviuru zvemitsipa zvinobatanidza musana wesipinha nemhasuru uye zvinogamuchirwa. Iyo yekunze yehutachiona system ndiyo inokonzeresa mafungiro, ayo anobatsira muviri kudzivirira kukuvara kwakakomba. Izvo zvakare zvine chekuita nekurwa kana kupindura kwendiza iyo inobatsira kukudzivirira iwe kana iwe uchinzwa kunetseka kana njodzi.

Ngatimboongororai mumwe neuron padyo.

Heino mhedzisiro yetsinga. Imwe yeimwe tsinga tsinga, kana fascicles, ine mazana etsinga dzemunhu.

Heino imwe neuron yemunhu, ine ayo madendrite, axon, uye sero muviri. Iwo ma dendrites akafanana nemiti-senge zvivakwa. Basa ravo kugashira masaini kubva kune mamwe mauroni uye kubva kune akakosha maseru enzwa anotiudza nezvezvakatipoteredza.

Sero muviri ndiro dzimbahwe reeuron. Ine DNA yemusero. Iyo axon inoendesa masaini kure nemuviri wesero kune mamwe mauroni. MaNeuron mazhinji akaputirwa sezvidimbu zvematare emagetsi. Kuputira kunovadzivirira uye kunotendera masaini avo kuti akurumidze kufamba achitevedza axon. Pasina iyo, zviratidzo kubva muuropi zvingangotadza kusvika mumapoka emhasuru mumakumbo.

Motokari mauroni anoitisa kutonga kwekuzvidira kwemhasuru kwese muviri. Iko kushanda kweiyo system yetsinga kunoenderana nekuti masururoni anotaurirana sei. Kuti chiratidzo chemagetsi chifambe pakati pemaviri mauroni, chinofanira kutanga chashandurwa kuita chiratidzo chemakemikari. Ipapo inoyambuka nzvimbo inosvika miriyoni yemasendimita yakafara. Iyo nzvimbo inonzi synapse. Iyo kemikari kemikari inonzi inonzi neurotransmitter.

Neurotransmitters inobvumira mabhiriyoni emauroni muhurongwa hwemitsipa kuti vataurirane. Ndozvinoita kuti tsinga dzive nyanzvi yekutaurirana yemuviri.
