I-pituitary gland iyindawo ebalulekileyo yokulawula edibanisa i-endocrine kunye neengxaki zomzimba womntu. IiHormones ze-pituitary gland zihlala ziphuhlisa iimveliso zeprotheyini ezijongene neenkqubo ezininzi ezenzeka ngaphakathi kumntu.
Ziziphi i-hormone eziveliswa yi-pituitary gland?
Ukwahlula phakathi kwe-lobes yangaphambili nangemva kwesimo se-pituitary gland, bangakwazi ukudibanisa isahlulo esiphakathi, kodwa ngokuqinisekileyo asikho. Ezi ndawo zenzelwe ukwenza imisebenzi yazo.
Cinga ngama-hormone asele e-lobe yangaphambili:
- TTG. Ihomoni ye-thyroid-stimulating yenzelwe ukulawula umsebenzi we-thyroid gland kwaye ilawula ukuhlanganiswa kwezinto T3 kunye ne-T4 ezinxulumene neenkqubo zokuxilonga, ukugaya ukutya kunye nenkqubo yesistim, kunye nokusebenza kwenhliziyo. Isixa esiphezulu kwezi zinto zikhokelela kwi- thyrotoxicosis .
- ACTH. I-adrenocorticotropic hormone ithintela umsebenzi we-correnx ye-adrenal, kwaye nayo inefuthe elincinci kwi-hormone yesondo. Ngaphezulu, loo nto igalela kwinkqubo ye-oxidation ye-fat, isebenzise ukuhlanganiswa kwe-insulin kunye ne-cholesterol kunye nokwandisa i-pigmentation. Ukuba ngaphezulu kwe-ACGT kwafunyanwa ngexesha lokuhlalutya kwe-hormone ye- pituitary, ngoko isifo sika-Itenko-Cushing singahamba, sihamba kunye nomfutho wegazi ophezulu, i-deposit deposits kunye ne-immunity immunired. Ngenxa yokusilela, i-disabling disorder occurs.
- STG. I-hormone ye-pituitary somatotropin ithatha inxaxheba kwiindidi ezahlukahlukeneyo ze-metabolism, ngenxa yoko kuphuhliswa kwendalo. Umphumo wokuquletheka kwawo kubantwana kuba yi-gigantism, kwaye ukugqithisa kubantu abadala kubangela i-acromegaly (ukukhula kwezicubu kunye nokuqina kwamathambo). Ukungonakali kukubanjwa kokukhula kumzimba omncinane.
- Prolactin. Le hormone inendima enkulu ekuveliseni. I-hormone inefuthe elikhulu kumzimba wesetyhini. Ngombulelo kuye, i-mammary gland iyakhula kwaye oomama baqala ukukhulula ubisi. Amanqanaba angaphantsi kwama prolactin angabangela iingxaki ngokukhulelwa kunye nokugqithisa.
- FSH neLH. I-follicle-stimulating kunye ne-lyutenizing hormone isenzo kwizintlu zesini, ukuvelisa iindawo eziphambili zenkqubo yokuzala yeprogesterone kunye ne-estrogen.
Amahomoni anoxanduva lokwakheka kwithuba elingaphambili le-pituitary gland elijongene nalo libandakanya oku kulandelayo:
- Oxytocin. I-hormone ichaphazela umzimba wesetyhini, uvuselela abasebenzi kunye nokuthatha inxaxheba kwi-lactation. Indlela echaphazela ngayo amadoda ayibonakaliswa.
- Vasopressin. I-hormone ye-Antidiuretic ikwandisa umthamo womnzi emzimbeni, ivuselela ukuxutywa kwamanzi kwiintsana zengqondo. Ukongeza, i-hormone inciphisa i-arterioles, ebaluleke kakhulu ekulahlekeni kwegazi.
Ukulungiselela amahomoni e-pituitary
Xa utyhila iinkqubo ze-pathological, ukubonakala kwayo ehambelana nokungahambi kakuhle kwe-pituitary gland kunye nokuveliswa kweemveliso zeprotheni ezisisiseko, amayeza akhethekileyo anqunywe.
Ukulungiswa kwamahomoni e-lobe yangaphambili ye-pituitary:
- Ukulungelelanisa umsebenzi wee-adrenal glands, ngakumbi kwimveliso ye-glucocorticoids, sebenzisa i-Sinaten Depot, i-Corticotropin, i-Corticotropin-Zinc.
- Ukukhuthaza ukuphuhlisa i-thyroxine kwaye uphucule umsebenzi we-thyroid, iTyrothropin iyalelwe.
- Ukuqhelanisa ukukhula kwamathambo kwaye kusebenze uphuhliso lomzimba wonke uthatha iSomototropin, Size, Humatrop.
- Ukuntuleka kwehomoni ye-follic-stimulation hormone kuhlawulwa ngokusetyenziswa kwe-phallitropin alfa kunye ne-beta. Ngelixa linye kunye nehomoni LH ithatha i-Pergonal.
- Amachiza ukuhlawulela ukungabikho kweprolactin ayiphuhlanga. Nangona kunjalo, i-Bromocriptine isetyenziswe ukuyivimba.
Ukulungiselela amahomoni e-post lobe ye-pituitary:
- Ukuphucula ukutyunjwa kwezihlunu ze-uterine kunye nokwakhiwa kobisi, ezinjalo izidakamizwa zinokumiselwa iSynthofinon kunye ne-Oxytocin Dezaminokistocin.
- Ukunyangwa kwesifo sikashukela, iLysinvazopressin ilawulwa, i-Pitioutrin ibandakanyeka kunye ne-oxytocin kunye ne-vasopressin, ebangela ukuba kukhishwe i-uterine.
