Reticular inotungamirwa. The ukama injini siyana

Brainstem reticular inotungamirwa ndiyo paumbwe plexiform, muzvizhinji pamusoro Neural zvivako, riri nechepakati zvikamu (thalami, midbrain uye medulla). Tutsinga tunofambisa mashoko utwu kuti kwayo, dzinosiyana kukura, neurite urefu, mamiriro. Vakapemberera zvavo batana ruka.

Mashandiro anoita mashoko reticular inotungamirwa

Órgãos yakabatana cerebellum, musana, cortex ari Hemisférios Cerebrais, chikamu ichocho ndicho chinoita (kupa siyana anokosha mumuviri) hurongwa. In paumbwe pajira riya dyidzana kukwira (afferent) nokuburuka (efferent) pulses. The pulses anogona kutenderedza uye yakavharwa Neural matunhu. Muchiitiko chino, kugara kushungurudzika inopiwa muna reticular nokuumbwa Tutsinga tunofambisa mashoko utwu dzimwe pamwero. Zvinoguma mumwe kuzvipira kuna mabasa akasiyana-siyana madhipatimendi ari nechepakati tsinga. Kugadziridza ukuru excitation pakati pajira riya inotungamirwa chiitwe kuhukura hemispheres.

Reticular inotungamirwa unotora nzvimbo vanokwanisa kupa kana kufambisa mashoko inhibitory nomugumisiro musana motokari zvavaifunga.

Kokutanga ukama pakati musana hunenge uye kweiyi munzvimbo dzakasiyana-siyana pajira riya inotungamirwa yakawanikwa I. M. Sechenovym. Zvadaro, neAmerican neurophysiologist Megounom pamwe kubatsirwa mudonzvo pachena nezvakaitwa Kuongorora Sechenov.

Saka, kana zvemagetsi kweiyi ari medial munda mu anesthetized tsoko nekatsi pane kumbomira zvakakwana kufamba, sezvo dzepanguva, uye anoita kweiyi injini munyika dzine ose cerebral cortex. Saka zvose akaputsa Fani kuti chinokurwadzai kuti reticular maumbirwo, kwave kuchiita nokushatiriswa muri bilateral zvakasikwa.

Kana pachena kune lateral reticular vakagadzira mapazi panguva arikunze, kushanda ane inhibitory mugumisiro nharaunda padzakacherechedza kufambisa sei musana motokari basa.

The reticular inotungamirwa anokwanisa kushanda musana dzidzo yakasiyana.

Zvinofanira kucherechedzwa kuti nzvimbo pajira riya inotungamirwa, tinazvo kufambisa zvazvinoita gwenya basa kunosvika anteriorly. Saka, vakafukidza kwete chete munzvimbo yacho medulla oblongata, asi kuti midbrain uye pons.

dzidzo Net zvinogona kukanganisa tsandanyama matauriro. Izvi rakavhurika nzvimbo R. girenayiti. neurophysiologist Swedish akaratidza kuti reticular nokuumbwa kunokanganisa basa wegamma injini Tutsinga tunofambisa mashoko utwu. axons dzavo napakati vanonzi "intrafuzarnym" tsandanyama fibers uye kushandisa basa rinokosha murau pamusoro chokutambudzika muviri kufamba uye postures.

munzvimbo dzakasiyana pamusoro reticular inotungamirwa vanogona kunobatsira simba pamusoro generalized hunhu cerebral cortex, vachiita zvose zviri munharaunda yacho.

Kuramba pajira riya inotungamirwa basa uye aikanganiswa siyana zvine maatomu akafanana achiparadzira muropa riri kuitwa humoral zvinhu (carbon dioxide, catecholamines, etc ..). Izviwo, zvinobatsira kuti kudyidzana pakati reticular inotungamirwa mu murau zvimwe autonomic mabasa.

Zvinofanira kucherechedzwa kuti adzidze ukama pajira riya inotungamirwa dzimwe subcortical zvivako, izvozvo akatibvumira kunatsiridza kuti zvivako zviri neurophysiological zvigadziriswe yezvakaita munhu inoti (marwadzo, kutsinzina, hope, kungwarira, mupfungwa uye motivational inoti nevamwe). Kushandiswa muna Medicine zveBhaibheri inoratidza nomumwe kwomuchipatara pamusoro CNS pathologies, ndeakaita nzira itsva zvimwe zvinetso dzokurapa.
