Isiseko izinto ezifanayo zenza iiseli chromaffin. Ezi seli uvumele ukuphunyezwa imisebenzi adrenal kuphuhliso ka emzimbeni catecholamine: dopamine, norepinephrine kunye epinephrine.

ixabiso adrenal ukuze yokucolwa emzimbeni womntu

Le adrenal cell eziliqela iincindi zamadlala elawula iinkqubo metabolic. Umzekelo, iihomoni glucocorticoid negalelo carbohydrate yokucolwa emzimbeni.

umsebenzi adrenal ekumiseleni eseleyo amanzi amtyuba

Ngenxa kwazo luqinisekisa ukuba ukuvelisa ulawulo yokugcina amanzi emzimbeni kunye nokuphunyezwa wezimbiwa ukutya. Le nkqubo ngokusondeleyo ukuya umsebenzi izintso kunye nezinto ukuba kuhlelwe kuzo.

umsebenzi adrenal Human zokuzilungiselela emzimbeni ukuba iimeko ezibangela

Le misebenzi ukuphuhlisa neurotransmitters ezithile (epinephrine, norepinephrine) ezichaphazela ukusebenza kwenkqubo onovelwano luvo, abathatha inxaxheba ekuqhubeni pulses. Ngaloo ndlela hormone data igalelo ngokutsha umzimba phantsi koxinzelelo. Bona ukwandisa izinga lentliziyo kunye noxinzelelo lwegazi, ukwanda ukubila, kuncitshiswa motility ye phecana zesisu kushukumisa bronchodilation.
