Ama-hormone egilo - izidakamizwa Indlala yegilo iyisitho inombolo amelwe umzimba womuntu thyroxin futhi triiodothyronine. Ngaphezu kwalokho, ezikhethekile izicubu nezindlala ukukhiqiza into okuthiwa calcitonin, okuyinto unomthwalo lokushintshisana kwe-calcium.

Ama-hormone egilo nemisebenzi yabo eyisisekelo. Ukuze ukwakheka compounds hormone kudingeka ethile iodine nama-amino acid ngokuthi tyrosine. Ukusebenzisa lezi peptides ethize hormone awela yangaphakathi lomzimba kanye, kanye ukusabalala samanje wonke okufiswa. Regulation of the zamagama hormone tireodnyh eyenziwa neurohormones kohlelo hypothalamic-pituitary.

Kuyaphawuleka ukuthi thyroxine, noma njengoba ibizwa, tetraiodothyronine, akakwazi ngokuthi esisheshayo, njengoba, ngokwesibonelo, triiodothyronine ekhuthele kakhulu. Phela, kwakheka ngobuningi kwale hormone is of thyroxine e namangqamuzana akhethekile izinso futhi isibindi izicubu.

Ukubaluleka la ma-hormone kunzima kakhulu overestimate, ngoba alawule cishe kuzo zonke izinqubo kungenzeka emzimbeni. Ngokwesibonelo, ubambe iqhaza ezinhlelweni zokwenziwa wokukhula kwamangqamuzana kwezicubu namaseli. Abakwazi kuthinte izicubu, okwandisa bayasidinga umoya-mpilo. Thyroxine ulawula umfutho wegazi futhi kungathinta amandla kanye nokuvama Kufinyeta of imisipha yenhliziyo. Ama-hormone egilo lokulondoloza ukushisa komzimba evamile, kodwa futhi kuthinte izinqubo ukubola bese zokwenziwa izinto.

Thyroxine futhi triiodothyronine ithonya isimiso sezinzwa. Ngokwesibonelo, ukwandisa umsebenzi locomotor, kanye ukulawula ezingeni sihlale siphapheme futhi ubuthongo. Laba basizi kakhulu ukwandisa umsebenzi womuntu engokwengqondo iphinde ibheke ijubane nenkambo izinhlangano engqondo.

Kepha calcitonin ke, njengoba kuye kwashiwo, inquma calcium evamile ne phosphorus in the ezicutshini zomzimba womuntu. Ikakhulukazi, le hormone izenzo ngqo ku osteoblasts, inkanuko umsebenzi wabo nokukhuphula izinga kwe-calcium uthwebule igazi labo kanye nezinye iziphuzo yasekhaya. Angase sikhuthaze umsebenzi osteoclasts. Yingakho indima yakhe ukwakheka nokukhula amathambo kubaluleke kakhulu.

ukwephulwa olungenzeka ibhalansi hormone. Ngeshwa, umzimba akuyona njalo wakwazi ukugcina izinga elithile -hormone. Ngakho-ke, kaningi iziguli kutholakala ukuthi uphethwe yini lesi sifo, okuyinto ngandlela-thile exhunywe ne kuphula umthetho we ngemuva kwama-hormone.

Ngokwesibonelo, cabanga ngokungahlonishwa kwama-hormone egilo kungaholela ukuthuthukiswa nesifo esibizwa ngokuthi myxedema. Kuvela elinye iqiniso elithakazelisayo wukuthi lokhu sifo ngokuvamile kutholakala insikazi, kuyilapho besilisa itholakala njalo.

Lesi sifo libhekene kahle amanzi ibhalansi emzimbeni. Abantu abagulayo akhononde ukuvuvukala njalo, nezinwele nobumpandla, abanye nokushintshashintsha kwezinga lokushisa komzimba izinkomba. Ngaphezu kwalokho, izimpawu myxedema kubhekwe ukukhuluphala okubi, ezinye izinkinga kwi yesimiso ngemilingo.

hormone okweqile namanje kakhulu ngcono ukugaya of amaprotheni compounds. Umphumela kwenhliziyo njalo, ukujuluka ngokweqile futhi ukushisa, kanye ebukhali kwesisindo.
