Mashandiro anoita Mahormone
Mahormone zvinhu zvakakosha muhurongwa hwemahormone emuviri, zvichishanda semakemikoro. Anogadzirwa nemahormone uye anotakurwa nemuropa kuenda kunhengo kana tishu. Mahormone anodzora mabasa akasiyana-siyana emuviri, anosanganisira kukura, metabolism, kubereka, uye kushushikana. Muchinyorwa chino, tichaongorora mashandiro anoita mahormone uye kukosha kwawo mukuchengetedza kuenzana kwemuviri.
1. Nhanganyaya kuMahormone
Homoni imwe neimwe ine chimiro chayo chemakemikari uye inokanganisa masero chaiwo nenzira dzakasiyana. Kune mapoka matatu makuru emahomoni zvichienderana nechimiro chawo: mahormone epeptide, mahormone esteroid, uye mahormone eamine.
– Mahormone ePeptide: Ane macheni mapfupi epolypeptide, ndiwo mhando yehomoni inonyanya kuwanikwa. Mienzaniso inosanganisira insulin neglucagon.
– Mahormone eSteroid: Akagadzirwa necholesterol uye anonyungudika mumafuta. Mienzaniso inosanganisira cortisol, estrogen, uye testosterone.
– Mahormone eAmine: Akagadzirwa kubva kumaamino acids akagadziriswa, akadai seadrenaline nethyroxine.
2. Kugadzirwa uye Kuburitswa kweMahormone
Maitiro ekugadzirwa nekuburitswa kwemahormone anotanga nekukurudzira kwekunze kana kwemukati, zvakaita sekuchinja kwehuwandu hweropa. Mahormone anobatanidzwa anosanganisira:
– Hypothalamus nePituitary: Inodzora mamwe mabasa akawanda egland kuburikidza nekuburitswa kwemahormone akadai seACTH, TSH, uye GH.
– Gland reGyroid: Rinogadzira thyroxine iyo inotonga metabolism.
– Adrenal Glands: Inogadzira cortisol neadrenaline zvinobatanidzwa mukupindura kwekushushikana.
Kugadzirwa kwemahormone kunogona kudzorwa kuburikidza nemaitiro asina kunaka, uko kuwedzera kwemazinga ehormone muropa kunoderedza kukurudzira kwegland rinoigadzira, nokudaro zvichideredza kugadzirwa kwehormone iyoyo.
3. Kutakurwa kweHormone
Kana mahormone angoburitswa, anopinda muropa kuti asvike kumasero anotarisirwa. Mahormone anogona kutenderera akasununguka kana kusungirirwa kumapuroteni eplasma:
– Mahormone anonyungudika mumvura (peptides nemapuroteni): Anowanzo tenderera muchimiro chakasununguka nekuti anogona kunyungudika zvakananga muplasma.
– Mahormone Anonyungudika Mafuta (MaSteroid neTyrosine Derivatives): Anowanzo batana nemapuroteni nekuti haanyungudike muropa, izvo zvinoadzivirirawo kubva mukuora nekukurumidza.
4. Mahormone Receptors uye Signal Transduction
Mahormone anoda mareceptor chaiwo pamasero anotarisirwa kuti ashande. Mareceptor aya anogona kuwanikwa pamembrane yesero kana mukati mesero:
– Masero Ekugamuchira Makero: Kune mahormone asingakwanise kupinda muplasma membrane, akadai semahormone epeptide. Kana akabatana, anotanga masisitimu ekutumira masaini mukati memasero akadai semapuroteni eG, ayo anokonzera maitiro akasiyana-siyana mukati mesero.
– MaReceptors emukati memasero: Mahormone mazhinji esteroid anokwanisa kupinda mumembrane yesero uye anosunga kune mareceptor ari mu cytoplasm kana nucleus, ayo anozodzora kunyorwa kwemajini muDNA.
5. Mhedzisiro yeMahormone paMasero
Mahormone anogona kuratidza mhedzisiro dzakasiyana pamasero anotarisirwa, zvichienderana nerudzi rwesero uye hormone iri kusanganisirwa. Heano mamwe maitiro ayo mahormone anoshanda nawo:
– Inodzora Metabolism uye Simba: Zvakadai se insulin inobatsira masero kutora glucose kubva muropa kana thyroxine iyo inowedzera chiyero che basal metabolic.
– Inodzora Kukura uye Kukura: Homoni yekukura inokurudzira kukura kwemasero emapfupa netsandanyama.
– Inodzora Kushanda Kwekubereka: Mahormone akadai seestrogen ne testosterone anodzora kukura kwepabonde uye kushanda kwekubereka.
– Mhinduro yeStress: Adrenaline inowedzera kurova kwemoyo uye kuyerera kweropa kuenda kutsandanyama panguva yekushushikana, ukuwo cortisol ichidzora metabolism yeglucose uye mhinduro yemuviri kumuviri.
6. Kutsauka muMaitiro eKushanda kweHormone
Kusagadzikana mukugadzirwa kana kushanda kwemahormone kunogona kukonzera zvirwere zvakasiyana-siyana. Hypothyroidism inoitika kana gland re thyroid rikasagadzira mahormone akakwana, zvichikonzera zviratidzo zvakaita sekuneta uye kuwedzera uremu. Kusiyana neizvi, hyperthyroidism, inokonzerwa nekugadzirwa kwakanyanya kwemahormone e thyroid, inogona kukonzera kudzikira kwehuremu uye kurova kwemoyo nekukurumidza. Chirwere cheshuga chimwe muenzaniso apo kusashanda zvakanaka kwe insulin kunotungamira mukusashanda zvakanaka kwe glucose metabolism.
7. Kurapa neMahormone
Kurapa matambudziko emahormone kunosanganisira kurapwa kwekutsiva mahormone kana kushandisa mishonga inochinja kugadzirwa kana kushanda kwemahormone. Semuenzaniso, kurapwa ne insulin kuvanhu vane chirwere cheshuga cherudzi rwekutanga kana kushandiswa kwe levothyroxine kurapa hypothyroidism. Uyezve, mune dzimwe nguva, kuvhiyiwa kana kurapwa nemwaranzi kunogona kutariswa kurapa maronda kana bundu rinoita basa zvakanyanya.
8. Tsvagiridzo neKubudirira Mumunda weMahormone
Tsvagiridzo yemahormone iri kuramba ichienderera mberi, ichipa kunzwisisa kwakadzama kwekuoma kwemaitiro emahormone. Semuenzaniso, kugadzirwa kwemishonga inokanganisa mahormone receptors kune mukana wekuderedza mhedzisiro yekurapwa nemahormone. Zvidzidzo zveEpigenetic zvinopawo nzwisiso itsva yekuti mahormone anogona sei kukanganiswa nezvinhu zviri munharaunda.
Mhedziso
Mahormone anoita basa guru mukuchengetedza homeostasis yemuviri. Kuburikidza nenzira dzakaoma uye dzakananga dzekuita, anogonesa muviri kupindura zvinobudirira kushanduko dzemukati nedzekunze. Kunzwisisa kwakakwana mashandiro anoita mahormone kwakakosha kwete chete kune sainzi yekurapa asiwo pakukura kwekurapa mune ramangwana. Mhinduro iyi inopindirana inoratidza kukosha kwekuenzanisa kwemahormone pahutano hwedu nekugara zvakanaka. Mukupedzisa, kuti mahormone aite mabasa awo emuviri zvakanaka, zvakakosha kuchengetedza mararamiro ane hutano, kusanganisira kudya kwakaringana uye kurovedza muviri nguva dzose.
