Halkee iyo sidee neurohormones waxaa la soo saaray? Waa maxay neurohormones iyo waxa ay tahay hawsha ay ku?

The qaab dhismeedka iyo hawlaha qanjidhada hormoonada jidhka waa barashada sayniska, sida endocrinology. Anshaxa kale uu qoraalkani qeexayaa kala duwan noocyada kala duwan ee hormoonnada, wada hadalka, Jidka ay formation iyo saamaynta on jidhka.

Waa maxay hormone ah?

xiriir Tani, gasho dhiigga iyo dhex gelin xubnaha kala duwan dhex. Sababo la xiriira waxqabadka maadooyinkaas waa la dhimay ama waxqabad ee unugyada kale, loo yaqaan diirada u kordhay. Hormoonnada iyada oo saamayn ku dhowaad dhammaan leeyihiin hawlaha muhiimka ah ee jidhka bini'aadamka. fiirsashada The xeryahooda ka soo saaray ku xiran tahay arrimo kala duwan. Gaar ahaan, markii ugu muhiimsan ee maalintii, da'da, dareenka iyo xaaladda jirka. hormoonnada ku dhex gasho dhiigga sida loogu baahdo, iyo reebay jidhka ka qaab oon doorsoomaynin in qiyaasta yaryar iyada oo bile ah ama kaadida. Waxaa jira noocyo kala duwan oo ah xeryahooda, kaas oo ay leeyihiin saameynta ay ku saabsan xaaladda aadanaha xad ka weyn ama ka yar. Qaar ka mid ah iyaga ka mid ah waa neurohormones. xeryahooda Kuwan waxaa soo saaray in meel gaar ah ee maskaxda. Maxay yihiin walxaha kuwanu? Sida hab neurohormones? Waa maxay saamaynta ay ku yeelanayso nidaamka ee jirka? On this ka dib.

Guudmarka

Inta aynaan u ogaato halka iyo sida ay u sameeyaan neurohormones, waa in ay fahmaan waxa walxaha kuwan oo dhan. Qeexidda laftiisa xidido ku leeyahay Greek. Waxaa la macno tarjumay sida neuron ah (neerfaha) + hormaino (abaari, riixay). Waa maxay neurohormones? Tani xarunta peptide bayoloji firfircoon. Waxay ku yimaadaan qanjirka pituitary iyo xeer u dhaqdhaqaaqa. Neurohormone sii daayay by hypothalamus ah. dhaqdhaqaaqa cadaalada sharci ah xeryahooda maaddo isgaarsiin hormoonada jidhka iyo nidaamka neerfaha kasta oo kale. Tan waxa u sabab xaqiiqada ah in unugyada neurosecretory leeyihiin dareen gaar ah neurotransmitters hawl - xeryahooda oo gudbin garaaca wadnaha inaad xubin ka shaqeeya ee dhammaaneysa dareemaha. Sidaas darteed, ay ka qayb kordhiyay in sharciyeynta waxqabad ee qanjidhada hormoonada jidhka inta lagu guda jiro horumarinta iyo kobaca ee u shaqeeyo.

kala soocidda

In category this, laba kooxood oo xeryahooda. Ka hore waa liberiny ah. Waxyaabahani waxay leeyihiin saamayn kobcinaya on saarka ee pituitary qarsoon tropic. In group this, gaar ahaan, iyo waxaa ka mid ah thyroliberin corticotropin, folliberin, lyuliberin, somatoliberin, melanoliberin, prolaktoliberin. The netsyrogormonov kooxda labaad - statins. Waxyaabahani soednieniya hakin qarsoon pituitary tropic. In kooxdan, gaar ahaan waxaa ka mid ah somatostatin, iyo prolaktostatin melanostatin. Sida ay natiijada waxbarashada, waxqabadka of neurohormones hypothalamus oo aan ku koobnayn oo kaliya kicinta ama Iscelin of-soo-saarka xeryahooda bayoloji firfircoon tropic. walxaha The awood u leeyihiin in ay saameyn ku geeddi socodka biosynthesis ah.

In taas oo meelaha waxaa lagu fuliyaa si ay u horumariyaan?

Waxaa la sheegay in kor ku xusan in wax soo saarka ee xeryahooda, kuwaas oo in aadanuhu waa la fuliyay in meel gaar ah ee maskaxda. Formation of walxahan waxay dhacdaa labadaba vertebrates iyo xawayaanka. Halkee iyo sidee neurohormones waxaa soo saaray in noolaha kale? In vertebrates, ku lug leh dheecaan ka mid ah xubno ka pinealocytes qanjirka pineal chromaffin unugyada ee medulla, ganglia iyo dareemaha dogob adrenal paraganglia autonomic iyo durugsan habdhiska. The neurohormones dhagaxyada secretory sida caadiga ah ku xidhaan in borotiinada side.

Tilmaamo qaar ka mid ah

Si ka duwan qaab classical of unugyada dareenka, taas oo soo saari falalkooda laliska dareemayaasha kiimikada - dhexaadiyayaasha, unugyada neurosecretory saaraan in cytoplasm ah (marmar dhif ah, in xuduntii) Xarunta gaar ah. xeryahooda Kuwan waxaa ugu horayn kala duwanaayeen dhammaato ee dareemayaasha (boosteejada) ee dhiigga, hemolymph, dheecaanka lafdhabarka iyo unugyada. Neurohormones saamayn nidaminayo on waxqabad oo ka mid ah xubnaha visceral (qanjidhada hormoonada jidhka, gaar ahaan) iyo habka dhexe ee neerfayaasha ah.

Waa maxay hawlaha unugyada neurosecretory? The hawlaha walxahaasi uu gacanta ku neurons classical. Axon ay la aasaasay synapses badan oo jidhka ah iyo appendages unugyada neurosecretory in ay leeyihiin awood u leh inay curiyaan iman kara tallaabo ah iyo faafitaanka wadnaha weheliyaan Axon ah.

The meesha iyo ka-fiirsashada

Ogaanshaha sida saxda ah meesha iyo sida ay u sameeyaan neurohormones, waa in ay tixgeliyaan ay qaybinta ee habka dareemayaasha jirka. In xawayaanka hoose xiriir noolaha waxaa diffusely qaybiyey. Phylogenetically tilmaamay fiirsashada meydadka cell neurosecretory in xarumaha kala duwan. Sidaas, waxaa jira raasamaal ah crustaceans ee-X jidhka, iyo cayayaanka, tusaale ahaan, in prototserebrume. Isla mar ahaantaana waxaa neyrogemalnye jirkooda iyo hab neurosecretory. In vertebrates, diiradda ugu dambeeyay ee meel gaar ah ee diencephalon ah (iyo sidoo kale kalluumaysto ee gobolka caudal ee laf dhabarta - urofize). Sidaas darteed, la aasaasay laba nidaam ugu weyn neurosecretory: caudal (kalluun oo keliya) iyo ku-pituitary hypothalamic.

marxaladaha kala duwan ee soo koraya

Halkee iyo sidee neurohormones waxaa la soo saaray? Avv xeryahooda la xiriira borotiinada side, waxaa lagu fuliyaa on ribosome ah. Raasamaal dhacdaa tubules of reticulum ku endoplasmic. kaabsal Elementary ugu dambeyntii sameeyay adag Golgi ah. Qaybahaasi, kuwaas oo ballaciisu yahay 50 500 nm leeyihiin baqshadda lipoprotein. Waxaa laga soocay xarunta electron-cufan ah. Waxa uu, ka bacdi, waxay ka kooban tahay protein side iyo neurohormone ah. Guuritaanka dhagaxyada ah waxaa lagu sameeyaa xagga Axon ah. Axon Qaar ka mid ah xiriir la qalintaanka in neurohypophysis ah. Qaar kale - iyadoo unugyada jilacsan ee adenohypophysis ah (inta badan ay qayb dhexe). In kalluun, ee Axon nidaamka neurosecretory caudal abuurtaa xiriir aksoventrikulyarnye. content xulashada Direct of dhagaxyada ah waa la fuliyay in database xiriir ah by exocytosis ama jirkooda taagayo neyrogemalnyh, meel intercellular precapillary iyo farqiga heerka kelli.

cudurada suurto gal

Neurohormones ku lug dayactirka hemostasis (biyo iyo cusbo, iwm), dhinacyo kala duwan oo shiid, sharciyeynta ee cabirida xaalada muruqa siman. Intaa waxaa dheer, ay sabab u tahay waxqabad ay xaqiijisay hawlgalka deggan ee xubno ka mid ah qanjidhada hormoonada jidhka ah. Waxaa sidoo kale loo arkaa howlgalka xeryahooda peptide kordhinaya falcelinta difaaca iyo la qabsiga ee u shaqeeyo. Gelida hemolymph galay dareeraha lafdhabarka ama unug, waxay leedahay saamayn nidaminayo dheer fog. In the case of xadgudubyo halis ah ee waxqabadka ee hypothalamus iyo soo saaraan, siday u kala horreeyaan, neurohormones hypothalamic, waxaa jira rabshooyin in wax soo saarka ee hormoonnada ee qanjirka pituitary iyo qanjidhada kale hormoonada jidhka. Ninka bilaabay si loo horumariyo noocyo kala duwan oo cudurro nidaamka hormoonada jidhka ah. Gaar ahaan, waxaa ka mid kaafi ah hypothalamic-pituitary, cudurka Cushing ee, Acromegaly, hypothyroidism iyo cudurro kale.
