Raws li cov tib neeg endocrine system regulates lub internal dab nyob rau hauv lub cev.

Lub endocrine system yog ib tug neeg nrog rau lub paj hlwb ntawm lwm yam uas tseem ceeb heev dab nyob rau hauv lub cev, muab lawv nrog thiaj li hu ua humoral kev cai thiab kev tswj homeostasis nyob rau hauv nws, piv txwv li, puab tshuav nyiaj li cas. Tej nrog mechanisms rau hauv cov tshuaj tshuaj xyuas nyob rau hauv kom meej qhov kev kawm endocrinology. Lub peculiarity ntawm lub cev uas merged lub tswvyim ntawm "tib neeg endocrine system" yog hais tias lawv tsis muaj excretory ducts rau hauv lub cev muaj kab noj hniav. Lawv muab lub txiaj ntsim ntawm nws cov pa, los yog cov tshuaj hormones, ncaj qha mus rau hauv cov ntshav thiab cov qog kua, tsis zoo li lub exocrine qog, sib txuas lus nrog ib tug ntau yam ntawm lub cev muaj kab noj hniav thiab kuj rau lwm cheeb tsam.

Lub endocrine system ntawm tus txiv neej yog txawv los ntawm lwm yam systems ntawm lub cev ntawm nws "nyob deb". Qhov no txhais tau hais tias tswj nyob rau ib feem ntawm lub cev yog nqa tawm tsis nyob rau hauv lub qhov chaw ntawm zus tau tej cov xws active tshuaj, xws li cov tshuaj hormones, thiab deb heev deb ntawm lawv. Piv txwv li, lub antidiuretic lawm yog ua nyob rau hauv lub pituitary caj pas, uas yog nyob rau hauv lub pob txha taub hau, thiab lawv ua muaj nyob rau hauv lub raum tubules. Tib yam nrog oxytocin. Nws tseem yog ib yam khoom neurohypophyseal tsam nyob rau hauv lub cranial kab noj hniav, thiab lub ntsiab qhov chaw ntawm daim ntawv thov - nws uterine musculature.

Lub endocrine system, txhua tus neeg muaj ib tug hierarchical ntaiv. Tag nrho nrog qog tsim lawv cov tshuaj hormones, yog raug rau tus ntawm cov hypothalamic-pituitary system, uas yog nyob rau hauv tib neeg saib xyuas ntawm lub paj hlwb kev ua si thiab cortical hlwb lug. Pituitary caj pas - ib qhov txuas ntawm lub qog ntawm lub theem sab thiab lub hypothalamus. Cov yav tas, perceiving lub teeb liab los ntawm lub paj hlwb ua "tso cov tshuaj hormones" (statins thiab liberiny) uas muaj feem xyuam rau lub pituitary hlwb thiab ua rau lawv paim yog nce los yog txo lub tso pa tawm ntawm Tropic cov tshuaj hormones. Tropic cov tshuaj hormones ntawm lub anterior pituitary kuj ncaj qha kev cuam tshuam rau qhov kawg kev kho vajtse. Piv txwv li, cov thyroid-stimulating lawm muaj feem xyuam rau tsuas yog tus glandular cov ntaub so ntswg ntawm lub qog caj pas thiab hormone lactotropic rau lub mis. Lub xaus ntawm tsab cai no yog ib yam kev loj hlob ntawm uas tsim nyog cov tshuaj hormones, uas, los ntawm cov ntshav thiab lymph cuam tshuam rau cov metabolism hauv, kev loj hlob, kev noj haus thiab kev loj hlob ntawm lwm yam kabmob thiab tshuab.

Raws li lawv cov tshuaj qauv, tag nrho cov tshuaj hormones yuav tau muab faib mus rau hauv plaub lub ntsiab pawg: glycoprotein, protein-peptide, steroid thiab cov amino acid. Lawv muaj peev xwm kuj yuav (raws li hais saum toj no) muab faib los ntawm nws lub cev kev txiav txim. Hypothalamic thiab pituitary cov tshuaj hormones yog pib cov tshuaj hormones, thiab tag nrho cov so - mus rau lub ua yeeb. Pib tswj lub siv cov tshuaj hormones.

Endocrine system dramatically ua txhaum qhov nqi koj tshuav nyob rau hauv lub cev. Los ntawm cov theem ntawm cov lesion yuav yog nyob ntawm seb cov kev soj ntsuam daim duab. Nws tseem yuav muaj kev cuam tshuam ntawm qhov xwm ntawm qhov txawv txav secretion kev lom tshuaj. Endocrine Pathophysiology nyob rau hauv nws sib txawv cov kab mob xws li hais tias yog hais tias tus lub cev yog cim txo nyob rau hauv lub tso pa tawm ntawm ib yam tshuaj, ces clinically nws yuav muaj rau hauv daim ntawv ntawm nws mob tsis txaus, thiab, raws li, vice versa. Ib qho piv txwv yog myxedema los yog hypothyroidism, yog significantly txo thaum thyroid muaj nuj nqi thiab nws ncaj qha opposite thyrotoxic goiter nrog overproduction ntawm lub qog cov tshuaj hormones.

Lub endocrine system ntawm tus txiv neej, nyob rau hauv kev phem ntawm lub kev vam meej thiab sai kev loj hlob ntawm cov tshuaj thiab nanotechnology, yog tseem tsis tau qoos kawm lub cev thiab tej hlab ntshav. Txawm li cas los, yog dab tsi nws yog twb paub science, uas cov kws kho mob-endocrinologists nquag koom nyob rau hauv kev kho mob thiab kev tiv thaiv ntawm pathological tej yam kev mob ntawm nws ua cov neeg mob lub neej ntau heev thiab zoo dua.
