Magetsi synapses ndi zizindikiro zawo

Synapses ali apadera ojambula zinchito, amene anakonza pakati pa maselo okonda. Iwo zimafalitsa ndi kusandutsa zizindikiro zosiyanasiyana. Synapses kuonekera mu mawonekedwe a thickenings malekezero ulusi mitsempha. Ndi thandizo lawo zikhumbo mitsempha kufalitsa maselo anzathu. Ntchito yaikulu ya synapse ali kufala intercellular kwa zikhumbo za mitsempha.

Gawo ndi kufotokoza mwachidule

Malinga ndi mtundu wa nyemba kulibe osokonezeka, mankhwala ndi synapses magetsi. Mankhwala amakhala kufala chizindikiro mu njira imodzi ndi amakulitsa izo, komanso depolarize hyperpolarizes postsynaptic kapena dera. Mothandizidwa ndi synapses mankhwala kumawonjezera plasticity mu kusonyeza, ndiyo munthu kusintha kukumbukira ndi liwiro la kuphunzira. The zamagetsi kufala olumikizidwa ku makina synaptic yomweyo, ndi chizindikiro ikuchitika mbali ziwiri. Kugunda HIV ndi palokha chifukwa cha nembanemba presynaptic. Komanso, synapses magetsi ndi kugonjetsedwa ndi otsika kutentha, komanso ena amadza kwa mankhwala a. mtundu synapses wosanganiza ndi mbali imodzi. Iwo kufanana kwa mankhwala ndi ma siginalo magetsi.

Kodi synapse magetsi?

synapses magetsi - ndi intercellular mapangidwe kudzera amene amaonetsetsa anamasulira malemeredwe zimachitika. ndondomeko izi zimachitika chifukwa maonekedwe a magetsi pakati m'madipatimenti awiri otchedwa presynaptic ndi postsynaptic. Mantha dongosolo la invertebrates ali ambiri synapses magetsi, pamene nyama pafupifupi kumeneko. Pamodzi ndi synapses magetsi ndi zachilendo nyama apamwamba. Ambiri, iwo ali mu mtima, chiwindi, minofu, komanso mu epithelium ndi minofu glandular. Synaptic mphanga mu synapses magetsi ndi kuchepera kwambiri kuposa mankhwala a. Chinthu chofunika kwambiri pa mtundu wa synapse n'chakuti pakati pa zi- ndi postsynaptic nembanemba kulibe mlatho wa zedi.

Zofunika magetsi synapses mtundu ntchito

Katundu wa synapses magetsi ali motere:

• kudya kanthu (kwambiri ntchito kuposa mu synapses mtundu mankhwala);
• kufufuza zotsatira kukomoka (chimangirizo za nyemba motsatizana pafupifupi ayi);
• odalirika kufala kwa malemeredwe;
• mkulu ductility;
• kusamutsa wina ndi mbali zonse.

Features dongosolo la

Kapangidwe ka kugula zamagetsi akuyamba ndi Kakhungu postsynaptic. Chotsatira ndi yopapatiza synaptic mphanga, chomwe tubules yopingasa wapangidwa zedi. Kumbuyo kudula ndi ili Kakhungu presynaptic. Pakati ndi semicircular synaptic zolengeza. Oblong synaptic kutha - amafotokozera yomaliza Kapangidwe ka synapse magetsi. Chifukwa kukhalapo kwa mapuloteni mamolekyulu njira pakati pa zi- ndi postsynaptic maselo, ayoni zochita kupanga ndi mamolekyulu zing'onozing'ono ndi amasamukira ku selo wina ndi mzake. synapse amakhala otsika kwambiri magetsi kukana. Pansi pa zikhalidwe izi, panopa ntchito kwa presynaptic maselo postsynaptic ndi pafupifupi kuuzimitsa.

Specific katundu zinchito

Mu synapses magetsi, pali mbali yapadera zinchito. Synaptic kuchedwa pafupifupi palibe. Apa pakubwera mu osachiritsika presynaptic, kenako ndondomeko akuyamba angathe yomweyo postsynaptic. The imeneyi pakati pa zimenezi akusowa. synapses magetsi kupereka HIV ndondomeko kokha - a malemeredwe. Mu mtundu uwu wa synapse wanyamula amgwirizano ngakhale kuti chifukwa cha makhalidwe a kuchititsa stereometric mu njira imodzi efficiently kwambiri. zinthu zosiyanasiyana (pharmacological, ikukhudzana etc.) ndi pafupifupi ziribe mphamvu pa synapses a mtundu magetsi.

Kodi chisangalalo mu synapses magetsi? masitepe ndondomeko

Kuchititsa munda (PD) - ntchito yaikulu yomwe akutenga synapse magetsi. Limagwirira cha ndondomekoyi ndi lofanana ndi PDP mu synapses mu ulusi mitsempha. Pamene malemeredwe masiwichi kuchita chitukuko sitepe, zosiyana mlandu akuyamba Kakhungu presynaptic. Chifukwa, zamagetsi, izi zimakhudza Kakhungu postsynaptic, kukhumudwitsa ndi amachititsa kuti kupanga PD. Conduction wa malemeredwe mu synapse magetsi ndi zovuta zokhudza thupi ndondomeko kuti kumachitika panthawi angapo. Kakhungu Presynaptic amachita kusintha kwa zimachitika magetsi kuti mankhwala, amene akupeza postsynaptic mbale kachiwiri kukopedwa mu mbendera magetsi.

Ena zopindika mu synapses magetsi

Ngakhale kuti synapses magetsi achite ndondomeko mwachilungamo yosavuta malemeredwe kutengerapo, iwo ndi zina zolakwika chachikulu. Ndipo mlandu stereotype zochita zawo. Kutheka kutengerapo mwachindunji maselo lakutali chisangalalo kumeneko. Zi- ndi postsynaptic maselo ogwirizana synapses magetsi mtundu, nthawi zonse mu malemeredwe chomwecho. braking maonekedwe zosatheka. Chifukwa cha kuperewera kwa onse pamwamba mu ubongo khanda si ambiri synapses magetsi, pomwe wamkulu ali angapo mu diso kwa diso, ndi tsinde ubongo ndi mizu ya zida za vestibular.

A ofanana, koma mawonekedwe a limagwirira pathological wa malemeredwe chifukwa cha matenda amene amagwirizana ndi alibe malire axon. Choncho, ndondomeko malemeredwe "kudumpha" kwa wina ndi axon wina, kungachititse kutengeka onyenga. Mwachitsanzo, maonekedwe a kumva kupweteka, ngakhale kuchotsa maselo ululu zotumphukira kumachitika chifukwa cha "Anakweranso" malemeredwe.
