Hea a pehea e hua neurohormones? He aha te mea te neurohormones me aha e ratou mahi?

Kei te ako te hanganga me ngā mahi o te repe endocrine he pūtaiao, rite mātai repe. Ka torotoro hoki te ako ngā momo o hormones, ratou pāhekoheko, te ara o ratou hanganga me te mana i runga i te tinana.

He aha te mea he taiki?

Tenei hononga, tomo te bloodstream me tomo te ngā whēkau i roto i reira. Nā ki te mahi o enei matū heke te nui haere mahi o ētahi atu pūtau, tuku ki rite ngā taumata ranei. Hormones roto i to ratou mana i runga i tata katoa i mahi faufaa o te tinana tangata. Ko te kukū o te pūhui hua whakawhirinaki i runga i ngā āhuatanga. I roto i ngā, i te wa nui o te ra, tau, aronganui me te huru tinana. Ko te taiaki ô te toto rite tika ana, a ka whakakorea i te tinana i roto i te puka taui i roto i ngā pukapuka iti i roto i te ate mimi ranei. He momo rerekē o pūhui, e whai he whānuitanga nui iti ranei te pānga i runga i te huru tangata. Etahi o ratou he neurohormones. E whakaputaina ēnei pūhui i roto i te wāhi ngā o te roro. He aha e enei matū? Ka rite ki te ara o neurohormones? He aha te pānga e whai ratou i runga i te pūnaha i roto i te tinana? I runga i tenei i muri mai.

Overview

I mua i te kitea tatou i roto i te wahi a pehea ki te hanga i neurohormones, kia matau ki ta enei matū i te katoa. Ko te whakamāramatanga ano he pakiaka Kariki. Kei te mau iritihia te reira i rite te neuron (karere) + hormaino (kaha ai, hoe). He aha te mea neurohormones? Tenei pūhui peptide kaha biologically. haere mai ratou i roto i te repe, ka regulates tona mahi. Neurohormone tukua e te hypothalamus. mahi Nā nga pūhui kaupapa fetu'utaki endocrine me ngā pūnaha io ki ia atu. Ko e tika ana ki te meka i ngā pūtau neurosecretory whai te tūtohutanga ngā ki mahi neurotransmitters tenei - pūhui e tuku pini ki te mema e mahi o te whakamutunga karere. Ko te kupu, atu ratou whai wāhitanga ki te tikanga o te mahi o repe endocrine i roto i te whanaketanga me te tupu o te rauropi.

whakarōpū

I roto i tēnei kāwai, e rua ngā rōpū o ngā pūhui. Ko te tuatahi ko te liberiny. Ēnei matū i te pānga whakaongaonga i runga i te hanga o te rapae o ngaro Tropic. I roto i tenei rōpū, i roto i ngā, me ngā thyroliberin corticotropin, folliberin, lyuliberin, somatoliberin, melanoliberin, prolaktoliberin. Ko te netsyrogormonov rōpū tuarua - statins. Ēnei hua soednieniya pōturi ngaro rapae o Tropic. I roto i tenei rōpū, ngā ngā somatostatin, me melanostatin prolaktostatin. E ai ki nga hua o nga akoranga, e kore e te mahi o neurohormones o te hypothalamus iti ki te whakaongaonga anake inhibition o hanga o kaha biologically pūhui Tropic ranei. Ko te matū i te kaha ki te whakaawe i te tukanga biosynthesis.

I roto i nei kawea wāhanga e i roto i ki te whakawhanake?

I mea te reira ki runga ake i kawea te hanga o enei pūhui i roto i te tangata i roto i roto i te wāhi ngā o te roro. Hanganga o enei matū puta e rua i roto i vertebrates me i hātaretare. E hua hea me pehea neurohormones i roto i te tahi atu rauropi? I roto i vertebrates, whai wāhi i roto i te secretion o te pineal pinealocytes repe āhuatanga chromaffin kikokiko i roto i te adrenal medulla, ganglia me te karere kahiwi paraganglia io autonomic me piringa. Ko te granules secretory neurohormones te tikanga here ki pūmua kawe.

ētahi āhuatanga

Rerekē te ahua puāwaitanga o nga ngā pūtau io, e hua matū ponana foaki karere - kaitakawaenga, hua ngā pūtau neurosecretory i roto i te cytoplasm (i roto i wā onge, i roto i te karihi) pūhui motuhake. E kitea ana ēnei pūhui matua i te hopearaa karere (terminals) i roto i te toto, hemolymph, inu cerebrospinal me te kiko. Neurohormones i te pānga e fakatonutonu i runga i te mahi o nga whekau visceral (repe endocrine, i roto i ngā) me te pūnaha io pokapū.

He aha e nga mahi o ngā pūtau neurosecretory? whakahaeretia nga mahi o enei āhuatanga e neurons puāwaitanga. Ratou axons i hanga synapses maha i runga i te tinana, me te mau hu'ahu'a pūtau neurosecretory e whai i te kaha ki te whakaputa i tētahi pūmanawa mahi me te horapa o te pini haere nga axons.

Te wāhi me te kukū

E mohio ana rite te wahi me pehea ki te hanga i neurohormones, kia whakaaro ratou tohatoha i roto i te pūnaha io. I roto i te hātaretare e tohaina raro kaiao hononga diffusely. tohua phylogenetically kukū tinana pūtau neurosecretory i roto i te pokapū tēnā. Heoi, i reira he whakaeminga o waimāori i roto i te X-tinana, me i roto i ngā ngārara, hei tauira, i roto i te prototserebrume. I te wa taua ki reira neyrogemalnye tinana, me te ara neurosecretory. I roto i vertebrates, te arotahi hou i roto i te wāhi ngā o te diencephalon (me te ika ano hoki i roto i te rohe caudal o te ua - urofize). Ka rite ki te hua, i hanga e rua pūnaha neurosecretory matua: caudal (ika anake) me te hypothalamic-rapae o.

ngā wāhanga o te whakawhanake

Hea a pehea e hua neurohormones? Synthesis o pūhui e pā ana ki pūmua kawe e kawea, i runga i te ribosome. puta haaputuraa i roto i te tubules o te kiriuwhi. pire Elementary hopea i hanga i roto i te matatini Golgi. Ēnei wāhanga, ko tona diameter ko i 50 ki te 500 nm whai lipoprotein pūhera. Kei te wehea te reira i te pokapū irahiko-mātotoru. Ia, i roto i te tahuri, ngā o te pūmua kawe me te neurohormone. kawea Moving te granules te ki te axons. Ētahi axons i roto i te whakapā ki tōiti i roto i te neurohypophysis. Etahi - me ngā pūtau glandular i roto i te adenohypophysis (te nuinga tona wahi takawaenga). I roto i te ika, i te axons o te pūnaha neurosecretory caudal hanga aksoventrikulyarnye hoapā. kawea ihirangi kōwhiringa Direct o te granules i roto i roto i te pātengi raraunga whakapā i te exocytosis ranei tinana pärönaki neyrogemalnyh, precapillary wāhi intercellular me i te āputa i te taumata rāpoi.

māuiuitanga taea

E whai wāhi Neurohormones i roto i te pupuri hemostasis (te wai, me te tote, me ētahi atu), āhuatanga ngā o pākia, ture o te āhua uaua maeneene. I tua atu, e tika ana ki to ratou mahi whakarite mahi pūmau o ngā āhuatanga o te repe endocrine. Kei te whakaaro ano hoki te reira i te mahi o pūhui peptide whai wāhi ki te tauhohe tiaki, me te urutau o te rauropi. Tomo i te hemolymph ki te inu cerebrospinal kiko ranei, to ratou he pānga e fakatonutonu roa tawhiti. I roto i te take o maumaui nui o te mahi o te hypothalamus me hua, aua, neurohormones hypothalamic, i reira he raruraru i roto i te hanga o te hormones i roto i te repe, ka tahi atu repe endocrine. timata te tangata ki te whakawhanake i te whānuitanga o mate o te pūnaha endocrine. I roto i ngā, ngā enei te iti hoki hypothalamic-rapae o, mate o Cushing, acromegaly, hypothyroidism me ētahi atu mau ma'i.
