Endocrine litsoelesa: sebopeho humoral molao oa tsamaiso tsamaiso e khopo

Boikarabelo bakeng sa tshebetso e nepahetseng ea tsamaiso ea tsohle le makala a monna jarelang boko, e leng setsi sa tlhōrōng ea hlahloba lesedi o tlang 'me sebaka sa tswakana ea ka matshwao a medumo e rometsoe ke lisele tsa shebiloeng holimo tsamaiso ea tse peli. 'Me haeba ka tšusumetso ea methapo e ikitlaetsa ka maqhama a mangata ka mofuta inehetseng oa lesela, e aposredstvenno humoral hlokomela e loketseng ho tsamaisa limolek'hule bioactive khona ho activating le receptor mehahong ka lisele tsa makala phofung. Tabeng ena, litsoelesa le endocrine ba lokisetsa ka tsela e khethehileng, 'me ena ke feletseng fapaneng ho tloha exocrine ena. Pele, exocrine litsoelesa secrete limolek'hule tsa bona ka ntle, ke hore, ka tikoloho. Sena se hloka hore ducts khethehileng excretory, eo na le endocrine tšoelesa lisele tse secretory eo a tšolotsoeng li-hormone toba maling.

Ho ke ke bohlokwa hore setsi sa phahame humoral molao oa tsamaiso e bokong, e leng e hypothalamus. Hae dinama tse nyenyane tse glandular se hlahang ho yona neural synthesizes statins, thibela ho tswakana tsa li-hormone pituitary, le liberiny fapana hore ho modulate mosebetsi oa eona. Ke phello ea eona ena ntlhapedi fihlellwa taolo ya mesebetsi ka mose tsamaiso endocrine litsoelesa mele. Ka tsela eo hormonal molao oa tsamaiso ya mesebetsi e mong setsi ke pituitary - sebopeho, ke ba ka bang 20 ka makhetlo a e nyenyane ho feta hypothalamus le, empa o etsa mesebetsi e hlokahala. Hape ke habohlokoa ho hlokomela hore e joalo e tšoelesa nyane etsa tswakana tsa metsoako macromolecular ka bongata, e leng ba bitsoa li-hormone, ha sebopeho godimo-boemo ba hlahisa feela statin le liberinami tse haholo bonolo lik'hemik'hale sebopeho, e le ke dipeptide.

E mong endocrine tšoelesa feela ho laoloa ke pituitary le secretion potoloho e itšetlehile ka mosebetsi oa tswakana hormone Tropic. Ka tsela eo neurohypophysis mong tsa maiketsetso 'me Adh taolo reabsorption ea limolek'hule metsi ka a liphio bokella ducts tsa nephrons, le oxytocin, ea neng a okametse pelehi uterine nakong ea mosebetsi o boima,' me litsoelesa mammary ea secretion lebese.
