Synapses Electrical me ratou āhuatanga

E motuhake Synapses hoapā mahi, e kua whakaritea i waenganui i ngā pūtau ka hikaka. tuku ratou ka whakaahua ke i te ngā tohu. puta Synapses i roto i te puka o thickenings i nga pito o muka karere. Ki te to ratou awhina ponana io tohaina ki ngā pūtau hoa. Ko te mahi matua o te synapse ko te tuku intercellular o ponana karere.

Whakarōpū me te whakamārama poto

E ai ki te momo o ngātere wa konatunatua, matū me synapses hiko. Chemical whakahaere tohu te tuku i roto i te kotahi aronga, ee faarahi ho'ii te reira, me te depolarize hyperpolarizes postsynaptic tuhaa ranei. faarahi Ki te awhina o synapses matū te plasticity i whakaoho, e ko, he tangata te whakapai ake mahara me te tere o te akoranga. kawea te roa tuimotu synaptic tuku hiko, me te tohu i roto i te rua ngā tohutohu. Ko motuhake i te pānga o te membrane presynaptic pini tuku. I tua atu, e ātete ki te pāmahana iti, me te etahi pānga i te rongoā synapses hiko. synapses momo whakauru i tetahi āhuatanga. He whakarara ki te matū me te kē hiko ratou.

He aha te mea he synapse hiko?

synapses Electrical - he hanganga intercellular roto i whakarite te tuku o te pini excitation. puta ana tēnei tukanga e tika ana ki te ahua o te nāianei hiko i waenganui i nga tari e rua i huaina presynaptic me postsynaptic. he maha nui o synapses hiko te pūnaha io o hātaretare he, i roto i ngā kararehe kei ratou tata ki reira. Fakataha ki te synapses hiko e tino noa i roto i nga kararehe teitei. I roto i te whānui, e ratou i roto i te ngakau, ate, uaua, me te i roto i te epithelium me kiko glandular. kapiti Synaptic i roto i synapses hiko he nui whaiti atu te matū. He āhuatanga nui o tenei momo o te synapse ko te meka e waenganui i nga kiriuhi mua- me postsynaptic te tīariari he piriti o ngā rāpoi ngota pūmua.

momo mahi synapses hiko nui

Āhuatanga o synapses hiko e whai ake nei:

• mahi nohopuku (nui mahi pai i roto i te momo synapses matū);
• pānga hemo Tuhinga (aofangatuku o ngātere whai o ngā kahore);
• tuku pono o te excitation;
• te kōngohe tiketike;
• whakawhiti ki tetahi me ngā taha e rua.

Āhuatanga o te hanganga

Ko te hanganga o te hihiko hiko haamata ki te membrane postsynaptic. Next Ko te kapiti synaptic kuiti, e ngā o tubules hake titoa o ngā rāpoi ngota pūmua. Muri te wāwāhi kei te membrane presynaptic. I roto i te waenganui ko te tohu synaptic ruawhetū. mutunga synaptic tapawhā - te huānga whakamutunga i roto i te hanganga o te synapse hiko. Nā ki te aroaro o te pūmua rāpoi takere i waenganui i ngā pūtau mua- me postsynaptic, katote pararopi me te rāpoi ngota iti e taea ki te neke i tetahi pūtau ki tetahi. Taua synapse he ātete hiko rawa iti. I raro i enei tikanga, te nāianei tono ki te pūtau postsynaptic presynaptic, me te tata tineia.

āhuatanga mahi motuhake

I roto i te synapses hiko, i reira e he maha o ahurei āhuatanga mahi. whakaroa Synaptic o tata kahore. mai hihiko ki te kāpeka presynaptic, a ka tīmata te tukanga pea tonu postsynaptic. Kei te ngaro te wā i waenganui i ēnei mahi. synapses Electrical whakarato tukanga tuku anake - o excitation. I roto i tenei momo o te synapse te pupuri më ahakoa te meka e tika ana ki te āhuatanga o te whakahaerenga stereometric i roto i te kotahi aronga tino tōtika. āhuatanga Various (pharmacological, waiariki, me ētahi atu) i tata kahore pānga i runga i nga synapses o te momo hiko.

Pehea he whakaongaonga i roto i synapses hiko? Ko te tukanga kaupae

A faatere mara (PD) - te mahi matua e tango te synapse hiko. Ko te tikanga o tenei tukanga ko rite ki te PDP i roto i synapses i roto i muka io. A, no te huri i te excitation ki te whakahaere i te whanaketanga taahiraa, he whakahokinga o te tiaki tīmata membrane presynaptic. Ka rite ki te hua, he nāianei hiko, e pā te membrane postsynaptic, irritating reira me faatupu te reira ki te whakaputa PD. Āriponga o excitation i roto i te synapse hiko ko te tukanga matatini whaiaroaro e puta i roto i te maha o ngā wāhanga. kiriuhi Presynaptic mahi te huringa o te pini hiko ki te matū, i te whiwhi i runga i paraharaha postsynaptic unu ano ki te tohu hiko.

Ētahi hē i roto i te synapses hiko

Ahakoa te meka e synapses hiko kawe i te tukanga tika ohie o whakawhiti excitation, to ratou etahi kohakore nui. A ki kupu i te stereotype o ratou mahi. Ko te taea o te whakawhiti tika ki tawhiti pūtau oaoa i reira. E hono pūtau mua- me postsynaptic synapses momo hiko, he tonu ratou i roto i te excitation taua. braking te ahua taea. Ka rite ki te hua o nga hē i runga ake katoa i roto i te roro tamaiti e kore ko te rota o synapses hiko, te mea i roto i te pakeke e tino he torutoru i roto i te etine o te kanohi, te kakau roro me pakiaka o te taputapu vestibular.

He rite, engari i roto i te puka o te huarahi pathological o excitation ko te hua o mate e kua pā ana ki tupu o nga rohe axon. Nō reira, ko te tukanga excitation "hūpeke" i tetahi ki tetahi axon, e kia arahi ki sensation teka. Hei tauira, te ahua o te sensation o te mamae, ahakoa te Karauna o receptors mamae piringa kia puta no te mea o "pekepeke haere" excitation.
