Central tsinga

The nechepakati tsinga inosanganisira uropi uye musana. Anoratidzika yokutanga yakaita flattened musana tambo zvishoma. A uropi, iri cranial mhango, rinoumbwa hemispheres vaviri, cerebellum uye Upfu.

The physiology zvomusoro tsinga anodzora ukama pakati mumuviri uye zvakatipoteredza, munhu dzekukurira mikana yakawanda yokukurudzira siyana. Uyewo nemhaka yake chakazadziswa Kufambisa zvomukati uye dzomuviri. Kazhinji, kwayakaita kunobva hunenge, sezvo muviri ikasakendenga kuchangotanga kuchinja dzakapoteredza kana zvemukati ezvinhu.

Central tsinga tsinga anoitisa kutaura nhengo yose kuburikidza cranial tsinga (12 yegwara) uye musana Midzi (ya31 nomwe). Of tsandanyama, ganda, chikamu makumbo uye zvomukati kuti "mashoko" vari chinopfuudzwa kuburikidza musana afferent tsinga vachimhanya kubva posterior kumidzi. Uye "mashoko" kubva skeletal tsandanyama iri vaipa kwairi Via efferent tsinga vachimhanya kubva posterior kumidzi. Kuvapo kana kusavapo hunenge anoratidza kuti musana, kana achichengeta kushanda dzepanguva. kukuvadza kwayo rinobatanidza kuchinjwa zvose kutyora kodzero pulses (uye afferent uye efferent). Kubva musana kuuropi uye shure ndizvo Neural makwara kuti zvinodiwa uye kuburikidza uropi hunde, pane zvisina kukwana kuvhiringidzwa kana magumo. Oculomotor, auditory uye optic tsinga midzi muna midbrain. Yerera kuzvidzora nevasori, kufamba kweropa, simba rinowanikwa mune iri diencephalon Via kukurukurirana zvaanonzwisisa (zvemukati uye kwokunze) kushanda kwemakemikari anobudiswa uye zvemwoyo nehurongwa. The cortex zvinosanganisira vakawanda Tutsinga tunofambisa mashoko utwu. Ndivo masero maumbirwo siyana, izvo vanoda akaturikidzana akawanda uye vari interconnected pachishandiswa kwendangariro. Chikamu chimwe nechimwe chezvinhu goko ane zvakasiyana Zvinoumba masero, rine chokuita mashandiro kuti anoita.

Zvose nechepakati tsinga, zvose madhipatimendi ayo ose achiita maitiro evanhu anoshanda sezvo rimwe Unit, nokudaro wezvamatongerwe dzichipfekeka hurongwa. Mumaonero nokunzwisisa izvi zviri pachena kuti chero maitiro, chero dzepanguva iri pakurukurwa zvikuru basa. Chero nguva, musimboti tsinga kunobva muviri zvinodiwa. Kutanga vanokurudzirwa chinangwa chinodiwa - nokuchinja zvakatipoteredza mukati mumuviri. Kubva pfungwa nemaonero neurophysiology kuitika mashandiro uyu simba kuburikidza subcortical nzvimbo cerebral cortex. Vakatuma avo pulses umo muviri vanoshayiwa zvikuru panguva iyoyo. Central tsinga anotsvaka kugutsa chikuru kukurudzira. Kuti izvi zvidaro, izvozvo synthesizes ruzivo zvose zvinowanikwa pamusoro ezvinhu kwokunze uye munyika ezvinhu muviri, uye ipapo zvokurimisa ari zvounhu chiito.

Kuvadza nechepakati tsinga kunoitika pamusana pezvikonzero zvakawanda. Izvi pakupona, uye murombo wokufambisa matambudziko kunotevera, migumisiro bundu kana chokutsva. Uropi uye musana kukura pamwe kuremara kana mudumbu anotevera njodzi sei: kuchinjwa mai panguva pamuviri, zvirwere, pachake kukuvara, kugara nemwaranzi, vari izvo pachena kuti zvine chepfu, udhakwa vabereki vose kana mumwe wavo. Not mudukusa muchinangwa panowanikwa abnormalities uye nhodzera dambe.

Kunyanya kuoma zvikanganiso kuitika apo apa zvinoita sei fetus pakutanga mwedzi pamuviri. Pakati pavo, nzvimbo yokutanga inogarwa hydrocephalus (ari ventricles uropi rinoungana zvakawanda cerebrospinal mvura) uye microcephaly (imwe underdeveloped pfungwa uye dehenya). Simba kukunda maitiro uye malformations pamusoro nomuzongoza uye dehenya.
