Indima ebalulekileyo ye-melatonin kulawulo lwesigqi se-circadian

I-Melatonin yi-hormone efihliweyo yi-pineal gland edlala indima ebalulekileyo ekulawuleni ubuthongo kunye neengqungquthela ze-circadian. indlela ye-melatonin kulawulo lwesigqi se-circadian.

I-Biosynthesis kunye nokukhutshwa kwemelatonin

I-Melatonin biosynthesis igqityezelwa ikakhulu kwi-pineal gland, kwaye inkqubo yayo yokudibanisa ichatshazelwa zizinto ezininzi, ezibandakanya ukukhanya, ubushushu kunye nezinto ze-neuroendocrine. umzimba ulala, ngelixa uncitshiswa emini ukugcina abantu bephaphile.

Indima yemelatoninkummiselo wesigqi esijikelezayo

Ungqamaniso lwe-melatonin kunye newotshi yomzimba: I-Melatonin inokunceda ukuhlengahlengisa iwotshi yethu yomzimba ukuyilungelelanisa kunye notshintsho lwemini yobusuku kwindawo engqongileyo.Ngale ndlela, isinceda siziqhelanise neendawo ezahlukeneyo zexesha kunye nemikhwa yokuphila.

IMelatonin kunye nommiselo wokulala wokuvuka: IMelatonin idlala indima ebalulekileyo kulawulo lomjikelo wokuvuka kokulala. ixesha elifanelekileyo kunye nokugcina amandla kunye nemveliso imini yonke.

Ukulawulwa kwemelatonin kunye nesigqi sobushushu bomzimba: IMelatonin ikwabandakanyeka kulawulo lwesigqi sobushushu bomzimba. inceda ekunyuseni ubushushu bomzimba kwaye igcine umzimba uphaphile.

Indlela ye-melatonin kulawulo lwesigqi se-circadian

Isenzo esithe ngqo se-melatonin kwinkqubo ye-nervous central: I-Melatonin inokusebenza ngokuthe ngqo kwinkqubo ye-nervous central, ngokukodwa i-nucleus ye-suprachiasmatic (SCN) ye-hypothalamus.

Indima yolawulo ye-melatonin kwinkqubo ye-endocrine: I-Melatonin inokulawula ukusebenza kwenkqubo ye-endocrine, ngakumbi ukukhutshwa kweehomoni ezifana nehomoni yedlala kunye ne-cortisol. ubushushu bomzimba, kunye nokulala.

Ingxelo yeMelatonin kwiretina: I-retina yezivamvo iyatshintsha ekukhanyeni kokusingqongileyo kwaye yondla olu lwazi ukubuyisela kwi-pineal gland kunye nobuchopho.Ukukhutshwa kwe-melatonin emva koko kuyatshintsha ukuziqhelanisa neemeko ezahlukeneyo zemini nobusuku.

Ukuqukumbela

I-Melatoninidlala indima ebalulekileyo kulawulo lwesigqi se-circadian. Isinceda ukuba siziqhelanise neemeko ezahlukeneyo zemini nobusuku kwaye sigcine iwotshi yomzimba esempilweni kunye nomjikelo wokuvuka wokulala ngokusebenza ngokuthe ngqo kwinkqubo ye-nervous central, ilawula inkqubo ye-endocrine kunye ne-retina. Nangona kunjalo, ngokugqithisileyo. ukuxhomekeka kwi-melatonin okanye ukusetyenziswa kakubi kwe-melatonin kunokukhokelela kuluhlu lweengxaki zempilo, ngoko kufuneka ulandele iingcebiso zikagqirha wakho kwaye ubeke ingqalelo kumgaqo wokumodareyitha.Ukuqonda okunzulu kwendima ye-melatonin kulawulo lwesigqi se-circadian kuya kusinceda siqonde ngcono indlela yokusebenza yewotshi yomzimba womntu kunye nokubonelela ngemibono emitsha kunye nezalathiso zophando lwebhayoloji kwixesha elizayo.
