The pfumbu nyaya uropi uye musana pfumbu nyaya

The nechepakati tsinga ndiye musana uye pfungwa. uropi fuma racho sezvamunoita yunifomu, chimiro chake chena uye pfumbu nyaya. White kumusoro tsinga fibers, avo pezvakaitwa, kuva, ukuwo, chena ruvara. Grey - nesumbu masero etsinga uye dzinotsanagura masero aya.

Spinal pfumbu

It akaumba yakakura kwazvo mhando nhatu Tutsinga tunofambisa mashoko utwu, izvo mumapoka chinoumba: radicular masero danda Tutsinga tunofambisa mashoko utwu masero yomukati. Zvayaiva mukati uye vakapoteredzwa chena nyaya. Inonyanya dzakabudirira dziri remuromo uye lumbar nomuzongoza, iyo chokuita kuwedzera motokari Tutsinga tunofambisa mashoko utwu.

Pakati pane huru mugero unomhanya yose kureba musana, uye zviri musimboti nawo. Huri chiteshi cerebrospinal mvura. It akapoteredzwa wachena nyaya, unonzi zvenguva. Pano, vachena nyaya inogona kupatsanurwa twin mberi, divi uye neshure aiwanzopiwa wokushanda mbiru. Nokudaro, muna muchinjikwa-chikamu nyanga nhatu: mberi, divi uye neshure.

Ectocinerea

musana rinopfuura pasina zvachinja medulla oblongata. Muganhu riri kuumbwa pakati elongated uye shure, inzvimbo dziri midzi wokutanga peya tsinga dzose musana. Madhipatimendi yokumusoro chikamu mukobvu kupfuura pasi. In uropi, elongated chinoumba vane basa nepakati, kufambisa, muviri, kufamba kweropa uye afemeruke. Hindbrain vanoumba zvikamu zviviri: zambuko uye cerebellum.

Bridge - chena chinotenderera riri pedyo mujinga uropi. Front unogona kuona muganhu pamwe makumbo uropi, uye shure - kusvikira medulla oblongata. A muchinjikwa chikamu vaiona chena nyaya uye ndachena musoro neerekitironi. Kuenderera medulla ndiye dorsal chikamu zambuko, sezvamakaropafadzwa chinoumba Switch hurongwa vanosarudzirwa uye cranial tsinga. Pano riri dzaitongwa pfumbu nyaya uropi. The cerebellum riri pasi seri uropi. Inoitwa hemispheres uye pakati chikamu - honye. Honye rinobatanidza hemispheres maviri. Cerebellum rukoko anofukidza pfumbu nyaya cortex pamusoro cerebellum izvo zvinoumba meanders. The chena fuma chinopinda gyrus. Above dzavo cover jena nyaya uropi. Mufananidzo-muchikamu zvakafanana zvikuru nomuti.

Pakati pfumbu nyaya nuclei inokosha uye chinokosha ndiko dzvuku musimboti kuti anoita rainyanya kukosha. Plumbing midbrain - rakamanikana mugero ane kureba masendimita maviri. It rinobatanidza ventricles, rwechitatu norwechina. mugero uyu runopoteredza pfumbu nyaya uropi, inova nechepakati uye rinoumbwa masero duku. The zvenguva pfungwa yacho ine nuclei enzvimbo kuti nzvimbo yaiva pasi goko, uye ndiye zvose zvamarudzi nehanya. Telencephalon, inoitwa zvikamu zviviri, kuti hemispheres maviri. Cerebral cortex uropi pfumbu nyaya muchimiro bwendefa. Zvinonzi inoumbwa masero etsinga vazhinji. Masero aya unogona kukamurwa akaturikidzana. Kuurungana, akavapindurawo, ane zvinhu chaizvo zvechiratidzo hwokuzvarwa mariri.

Saka, wachena nyaya - boka iyi Tutsinga tunofambisa mashoko utwu uye dendrites. Kuzara kunoitika nechepakati tsinga, izvo zvinoumba munhu musana uye pfungwa. Izvi zvinhu anoumba chepfungwa cortex uye subcortical nuclei. Fuma iri musana chakaumbwa masero etsinga, izvo pane vanenge mamiriyoni gumi. Vhoriyamu vachena nyaya iri muuropi anokwanisa kufurira pachiyero rezvedzidzo kukura. Zvinotarisirwa kuti kweimwe mari vachena nyaya yekudyidzana nokukurumidza kubudiswa mashoko.
