Ko te pewa pūpū

pewa kahuki - ko te ara e haere te hihiko karere ki te tinana e mahi i runga i te mau farii ohipa me hoki. Kei a ia ko e rua haurua. Te matatini pewa kahuki matatini hanganga me te mahi ko te mowhiti kati.

Hua i roto i te hawhe o reira ngā o neuron rongo piringa. puta tona pūtau i roto i te ganglia tuaiwi intervertebral ranei. te mawehe reira i te wehewehe ki pihi e rua ona peka. Kotahi wahi o reira ka rite ki te wahi o te io piringa haere ki te taha me te pito i roto i tetahi rohe o te kiri, kiko hohonu membrane mucous o te pūrere kāpeka ranei. Ko te peka tuarua he wahi, ngā i roto i te hikumārō pakiaka i roto i te ua.

Ko te neurons rongo i roto i reira e taea te mahi i te ara rerekē. Etahi tahuri ake a kahore tu, haere mai ratou ki te oblongata medulla. Etahi mutu i roto i te mea hina. I te wa ano i ia o te neuron tairongo i roto i te taonga ua haere i roto i ngā tohutohu rerekē manga collaterals ranei. E patua etahi o ratou i roto i te mea hina i roto i te pūtau pūkaha i roto i te haona me mutunga manga mārōrō,. Just mutu me te nekeneke neuron pokapū. e kore te mea hoapā poka noa te faitatau. Ko tenei e tika ana ki te meka i te pewa pūpū i roto i te wahi sentient o te tākaro i te tūranga rite ki te ara pyramidal.

E whakangau ke wahi ngā o piringa neuron nekeneke. takoto ana pūtau i roto i te haona he mārōrō, o te mea hina i roto i te ua. No reira e turai te tukanga ki te tuatahi i roto i nga uaua tuaiwi (nekeneke mua), ka i roto i te karere piringa.

Kaupapa pūpū pewa turi kahuki kau peia i hanga i roto i te hopearaa i memenge o neurons rite ki te hua o te pānga waho (pānga hama). Na roto i te ritenga o te karere femoral tomo te ua. Mai i tenei excitation tuku te i roto i te pūtau pūkaha o te mea hina, a atu - ki te uaua. Nā ki tona whakaiti puta te faaafaro i to'na waewae i roto i te tahi turi.

Rua haurua o e ngā pewa pūpū, i roto i te whakapā ki ia atu.

Ahakoa te meka e te mea te mahi pūpū ki kia motuhake, me te motuhake i roto i te pā ana ki te roro, e kore e pera. ara Pyramidal hipokina hoki perednerogovuyu manga whare herehere kāpeka. Ko te kupu, i roto i etahi ara kakapa atu ki te pewa pūpū, he reira i roto i te whakapā ki reira.

I roto i te pā ana ki ona ngā mahi mahi neuron pokapū te decelerating. I roto i ngā, āwangawanga reira nga reflexes iohere.

No te mea ko nga uaua i raro i te mana o te mau mana'o e ahu, e ngā te pewa pūpū, Na, i te wāhi ariā o te tirohanga, ia o ratou e taea e whakapataritari nekeneke kahuki. I tua atu timatanga, a pea ki reira he whakaiti whai wāhi tau tōpu matatini atu muskulaturnye rōpū.

Ko te kupu, kia waiho ai rawa he nui nui takahi whaihua reflexes nekeneke. Heoi, i roto i te mahi, e ratou nui iti. Mahalo he tika ki te inhibition nui (i roto i ētahi wā ki runga ki te whakangaromanga) e reflexes pyramidal tenei.

Ko te wāhanga o arcs pūpū e:

- receptor, Tārewa o whakaongaonga te taiao, me te tahuri i te reira ki ponana io;

- Ara afferent e rere i te mōhiohio tuatahi tukatuka wahi ki te CNS;

- Center "whakautu" (he huinga o neurons, i roto i nei tukatuka mōhiohio kei te ka hanga e pūpū);

- efferent ara ki te taha o te pūnaha io pokapū;

- actuator (rino uaua ranei);

- urupare.

Tei runga i te matatini, ka taea e te motini io hihiko kati kia ohie. I roto i tenei take wahi o te pewa pūpū, ngā o rua neurons (nekeneke me te mana'o). pūnaha Matatini i huaina pewa polysynaptic. Kei a ia ko e toru, neke atu rānei neurons.
