Whakarōpū o hormones. Ko te tūranga o hormones i roto i te tinana tangata

huaina hormones kaipōti matū o te pūnaha oti o ture o mahi tinana. Tenei matū ere rerekē ahei ki te tuku tohu pūtau. enei taunekeneke Ko te hua o te huringa i roto i te ahunga me te kaha o te ka pākia, tupu me te whanaketanga, te whakarewanga o ngā mahi nui ranei ratou pehanga me te ako.

Taiaki - Ko te kōtuitanga matū organic e puta i roto i repe endocrine wahi endocrine ranei konatunatua repe endocrine. E tohaina ratou tika ki te taiao ā-, i roto i nei te matapōkeretia tohaina, ka kawea ki te ngā whēkau. Here E taea e ki te faaitoito i te pānga koiora mohio nei e te tikanga o receptors ratou. No te mea ia taiaki he pū motuhake mo te receptor ngā. Tenei te tikanga e pā enei matū kotahi mahi tukanga ranei i roto i te tinana. whakaaturia Whakarōpū i te mahi o hormones, kiko tropism me ki te hanganga matū kei te mārama ake.

Ko te whakaaro whānui o te faufaa o hormones

whakarōpū Modern o hormones whakaaro enei matū i ngā maha o te tirohanga. A e tahoê ratou i te mea kotahi: he taiaki i huaina pūhui organic, puta noa i roto i te tinana nei kōtuitanga. He āhuatanga o te tata vertebrates katoa i roto i te mea ano hoki te ture o mahi tinana te humoral mahi pauna me ngā pūnaha io ratou aroaro. A puta reira i mua atu i roto i te phylogeny o te pūnaha ture humoral io. Ahakoa i roto i nga kararehe i tahito i ia, ahakoa ko ia te kawenga mō te mahi tino taketake.

Hormones me matū kaha biologically

Kei te whakapono te reira e te tino pūnaha o koiora matū kaha (BAS) me receptors motuhake hoki ratou he āhuatanga noa hoki ngā pūtau. Heoi, ko te ariā o "taiaki" me "BAS" e kore e ōrite. Taiki huaina BAS, e huna ana nei ki te taiao ā- me he te pānga o te rōpū tawhiti o ngā pūtau. BAS, i roto i te tahuri, mahi rohe. Tauira o matū kaha biologically, e kua kīia hoki ki rite matū taiaki-rite he chalones. E tukua ēnei matū taupori pūtau, Tautāwhitia uri ai me whakahaere i apoptosis. He prostaglandins hoki tētahi tauira o BAS. whakarōpū Modern o hormones tukuna ki a ratou i te rōpū motuhake o eicosanoids. 'Oku fakataumu'a ratou mo te ture rohe o mumura i roto i nga kopa, me te ki te kawe i nga tukanga hemostatic i te taumata o arterioles.

Matū whakarōpū o hormones

Hormones e wehea ki te maha ngā rōpū hanganga matū. wehe ratou ko te huarahi o te mahi tenei, no te mea i enei matū rerekē tropism mahi ki te wai me te lipids. Ko te kupu, ko te whakarōpū matū o hormones ko e whai ake:

• rōpū peptide (tohaina e te repe, te hypothalamus, nga repe taiaki, me repe parathyroid) ;
• rōpū pūtaiaki (tohaina endocrine wahi o gonads tane me ngā wāhi adrenaline);
• he rōpū o pärönaki waikawa amino (i hanga e te repe thyroid me apa roro adrenal);
• (E synthesized miramira pūtau i te waikawa arachidonic) rōpū o eicosanoids.

Ko reira taa'eraa e whakaurua hoki hormones sex wahine i roto i te rōpū pūtaiaki. Heoi, he e te steroids me kahore e nui: e kore e te mana o hormones o tenei momo e pā ana ki te pānga anabolic. Ko te kupu e kore e ratou pākia arahi ki te hanganga o te 17-ketosteroids. hormones ovarian, ahakoa te hanganga rite ki ētahi atu steroids, engari e kore e ratou. No te mea kei te synthesized ratou i cholesterol, ki faaohie whakarōpū taketake matū, e runga e ratou kia rite ki te toenga o steroids.

Whakarōpū i te wahi o te ariā

kia wehewehea āpiha hormonal me i te wahi o te ariā. Ētahi e hanga e i roto i te kopa piringa, i ētahi atu - i roto i te pūnaha io pokapū. I runga i tenei, tei te ara te secretion me tuku o te taonga e ai te iteraa ngā o ratou pānga. Whakarōpū o hormones i roto i te wahi rite tenei:

• hormones hypothalamic (tuku āhuatanga);
• rapae o (Tropic hormones, vasopressin me te oxytocin);
• thyroid (calcitonin, triiodothyronine me tetraiodothyronine);
• parathyroid (taiki parathyroid);
• nedpochechnikovye (norepinephrine, epinephrine, aldosterone, cortisol, androgens);
• sex (oestrogens, androgens);
• pancreatic (glucagon, taiāki huka);
• papanga (leukotrienes, prostaglandins);
• hormones With (motilin, gastrin, me ētahi atu).

e kore e matau tino te rōpū whakamutunga o matū hormonal. Kei te synthesized te reira i roto i te rōpū nui rawa o repe endocrine kei roto i te wāhanga o runga o te whēkau, ate me te taiaki. Ratou whakaaro, ko te ki te whakahaere i exocrine secretion o repe kūnatunga me te motility intestinal.

Whakarōpū o hormones i runga i te momo pānga

Various matū hormonal i ngā pānga rerekē i roto i te kopa koiora. E wehea ratou ki te rōpū e whai ake nei:

• tauwehe pūkoro (glucagon, triiodothyronine, tetraiodothyronine, cortisol, taiāki huka);
• mana mahi o ētahi atu repe endocrine (hypothalamus tuku āhuatanga, hormones rapae o Tropic);
• tauwehe o te konupūmā me te ūkuikui pākia (parathyroid taiki, calcitonin me calcitriol);
• tauwehe taurite wai-tote (vasopressin, aldosterone);
• tauwehe o te mahi whakaputa uri (hormones sex);
• hormones stressor (norepinephrine, epinephrine, cortisol);
• ngā mana me tauwhāiti te tere tupu o te wehenga pūtau (tupu taiki, taiāki, tetraiodothyronine);
• tauwehe o te io pokapū pūnaha, te pūnaha limbic (hydrocortisone, taiaki adrenocorticotropic, testosterone).

Ko te secretion o hormones me transportation

Secretion o hormones puta tonu i muri i to ratou kōtuitanga. hinga ratou tika ki te toto kiko ranei wai. wahi whakamutunga secretion āhuatanga o eicosanoids: e kore me ratou mahi atu i te pūtau, no te mea te mahi o ture te papanga katoa o te taupori. Na hormones ovarian, rapae o, repe taiaki, me ētahi atu i te horapa toto puta noa te tinana i roto i te rapu o te okana ūnga e whai receptors motuhake mo ratou. Mai i te toto whiwhi ratou i roto i te wai intercellular, e kua tonoa ki te pūtau o te okana ūnga.

whakawhiti Tohu i runga i te receptor

Ko te whakarōpū i runga o hormones whakaata te taonga o te pānga i runga i nga kopa me okana. Ahakoa he taea tenei i muri anake i te here o te matū ki te receptor. He rerekē Tata me e kei i runga i te mata o ngā pūtau, me i te cytoplasm, i runga i te membrane karihi, me te i roto i te karihi. No te mea te tohu huarahi e wehea matū tuku ki e rua momo:

• tikanga tuku wahopūtau;
• transduction tohu.

Tenei whakarōpū taketake o hormones taea ki te whakatau e pā ana ki te tere tohu tuku. Hei tauira, he tino tere atu i te intracellular i te huarahi wahopūtau. Ko reira huru o te Adrenaline, noradrenaline me ētahi atu hormones peptide. he angamaheni hoki steroids lipophilic tikanga Intracellular. Ano, hoki tutuki te painga o te kaiao te tere i roto i te kōtuitui o peptides he. I muri i hanga o hormones pūtaiaki, he nui pōturi me pōturi hoki ratou tohu transduction tikanga hei akiaki kōtuitanga pūmua me te matuatanga.

momo kē āhuatanga

He āhuatanga o hormones peptide, e kore e taea te i te tiki i muri te membrane cytoplasmic ki te cytoplasm kahore te pūmua taraka motuhake te tikanga wahopūtau. e kore te Mō se whakaratohia, ka tuku te tohu kei roto i te pūnaha cyclase adenylate mā te huri i te conformation o te complexes receptor hoki ia.

Ko nui ohie tikanga Intracellular. Kei te kawea te reira i roto i muri i te kătahi o matū lipophilic ki te pūtau, te wahi e tutaki ai ki te receptor cytoplasmic. Ki te a ia, hanga ana e ia te matatini taiki-receptor, e tomo te karihi, me te he pānga i runga i ngā ira motuhake. arata'i ratou whakahohenga ki te tīmata te kōtuitanga pūmua, i te mea te pānga rāpoi o tenei taiaki. Ko kē te pānga tūturu te pūmua e regulates te mahi e hiahiatia ana i muri i tona kōtuitanga me te mātauranga.
