Parathyroid timadzi: ntchito, mmene pa thupi la munthu

zopangitsa Parathyroid, kapena molondola iwo adzatchedwa parathyroid - wodziimira wophatikizidwa chiwalo cha katulutsidwe mkati. Amakhala ndi mitundu iwiri iwiri ochepa zopangitsa endocrine chowulungika. Iwo ili kumbuyo padziko chithokomiro England, mitengo yake yonyamulira chapamwamba ndipo m'munsi.

Parathyroid timadzi (dzina)

Parathyroid timadzi synthesizes awiri. Parathyroid timadzi - ndi parathyroid timadzi (PTH) ndi calcitonin.

Parathyroid timadzi (PTH) - uyu ndi chinsinsi chachikulu cha thupi. Parathyroid timadzi nalo dzina lake pa limba la katulutsidwe mkati, umene umabala iwo, mwachitsanzo ku England parathyroid. A dzina calcitonin odziwikiratu - kuchepetsa ndende kashiamu mu seramu magazi.

Mahomoni, parathyroid , ndi mmene pa thupi la munthu

Ife tinapeza chimene mahomoni omwe apanga England parathyroid. Tsopano tiyeni tikambirane za ntchito imene ali ndi udindo. mahomoni Parathyroid zofunika m'thupi.

Parathyroid timadzi (PTH) ndi puloteni pawiri muli chitsulo, asafe ndi sulfure. timadzi Izi apanga mosalekeza.

• Pamene ikuchitika nawo mafupa ndi kudzikundikira kashiamu mu mafupa - chinthu chofunika kuti zipangitsa mphamvu ya fupa.
• Komanso, chinsinsi cha England parathyroid kumapangitsa osteoclast ntchito, omwe ali ndi udindo achire kashiamu fupa mu magazi. Zimenezi zimathandiza kuti akhalebe pa zinthu zoyenera kashiamu mu mafupa ndi magazi. Komanso, mu dongosolo chigoba lili 99% calcium, ndi seramu 1 yekha%.
• ayoni kashiamu zimakhudzidwa kufala kwa zikhumbo za mitsempha, ntchito minofu contractile. Kashiamu ndi yofunika zikuluzikulu za dongosolo coagulation magazi ndi imayendetsa zimene michere ena.

Calcitonin ndi udindo kuchepetsa woipa kashiamu m'magazi ndipo apanga si nthawi zonse koma hypercalcemia.

Choncho, mahomoni parathyroid ndi ntchito zawo zofunika m'thupi la munthu. Iwo nawo ndondomeko zofunika kagayidwe kachakudya.

Zimene timadzi parathyroid ziwalo zina

mahomoni Kodi parathyroid zofunika kuti fupa, ife tinapeza. Tsopano timaganizira za zotsatira zawo pa ziwalo zina.

• timadzi Izi ochitachita zotsatira zake pa dongosolo mkodzo. C excreted ndi impso anasonyeza kuchuluka kwa calcium. ndondomeko izi zikuchitika pansi pa ulamuliro wa timadzi parathyroid.
• Parathyroid timadzi amathandiza kashiamu mayamwidwe ku intestine kakang'ono mu magazi.
• timadzi Izi amachepetsa kashiamu mafunsidwe mu diso mandala.

Hypofunction ya England parathyroid

Parathyroid timadzi pa hypofunction ake opangidwa zedi osakwanira. ntchito Anazunzidwa ya England parathyroid ndi otchedwa tetany, khunyu kapena matenda. Choncho excitability ya ubongo ndi kwambiri kuchuluka. Mu ena minofu nthawi anati fibrillar chidule kutembenukira mu khunyu nthawi yaitali. Zikavuta, kupweteka ntchito kwa magulu onse a minofu, kuphatikizapo dongosolo kupuma, chifukwa mu mpweya mtima wa asphyxiation (suffocation).

Mu nkhani ya kupitilira pang'onopang'ono waulesi odwala tetany angakhale nayo matenda okhudzana ndi dongosolo m'mimba, mavuto mano, ndi kukula osauka tsitsi ndi misomali.

mahomoni Parathyroid kukhala yachibadwa magazi kashiamu ndende. Bwinobwino izo ranges kuchokera 2.1 kuti 2.5 mmol / l. Pamene tetany mu mlingo seramu kashiamu sasefukira pamwamba 2,12 mmol / l. Umboni osati kupotokola minofu, mantha, ndi odwalawo zambiri amadwala tulo.

Hyperparathyroidism

Parathyroid timadzi mu hyperfunction ake apanga owonjezera. Izi angayambe pamene overactivity ena zigawo zopangitsa za endocrine. Zimenezi zimabweretsa matenda aakulu kugwirizana ndi kashiamu vutoli mu seramu magazi. Chotero chikhalidwe wotchedwa hyperparathyroidism alandire njira pathological:

• Parathyroid osteodystrophy.
• Hypercalcemia.

Zizindikiro za hyperparathyroidism

Zizindikiro chachikulu hyperparathyroidism ndi nonspecific:

• Mphwayi, ulesi, ndi kufooka.
• Okwiya.
• Kunyansidwa ndi kuchepetsa kapena kukana kudya.
• Kudzimbidwa.
• Kupweteka kwa mfundo ndi mafupa.

mwina kungakhale aakulu hyperparathyroidism hyperfunction zopangitsa, mlingo wa kashiamu mafupa yafupika ndi magazi M'malo mwake, kuchuluka. Mafupa kukhala Chimaona odwala zimenezi, pali matenda a dongosolo m'mimba, ndipo pali mavuto a dongosolo mtima.

Hyperfunction angayambe chifukwa kuchuluka kwa parathyroid anagawa gawo. Mwazi wa odwala otere zimadaliranso owonjezera kashiamu ndi owonjezera ossification mafupa. Odwala kungakhale kudzimbidwa (m'mimba, kusanza). Kuyambira wamanjenje dongosolo pali wotsikirapo excitability, ulesi. Ndi chitukuko zina matendawa akhoza kuoneka mafupa curving (mapindikidwe wa thorax ndi msana). Odwala mu miyezi ingapo kwambiri kuonda - mpaka makilogalamu 10-15 miyezi 3-4. Pakhoza kukhala excitability osakhalitsa, amene Kenako anasiya ulesi. chikhalidwe ichi amafuna mankhwala mwamsanga chifukwa Anapezerapo mu Zikavuta, likhoza mu imfa ya wodwala. Mu nkhani ya zizindikiro zofanana ayenera kuvula kuwona dotolo, ndi bwino m'thupi yemwenso ndi.

Mankhwala a matenda a England parathyroid

Ife tinapeza chimene ntchito imagwiridwa ndi timadzi parathyroid. Malfunctions wa zopangitsa za endocrine anafunika kudzudzulidwa. Hypofunction ankachitira zosavuta. Wodwala ayenera perekani angapo mankhwala ndi zakudya zolondola ndi bwino sunbathing. Izi bwino mayamwidwe kashiamu ndi thupi, chifukwa pakuti ichi tiyenera vitamini D, amene amapanga khungu lathu poyera kuti kuwala ultraviolet.

Chithandizo hyperfunction za thupi zokha ndi opaleshoni. Zimenezi zimaphatikizapo kuchotsa okha kutupa gawo parathyroid. Kwathunthu kuchotsa thupi sizingatheke, chifukwa kungachititse kuti zopweteka kusalankhula ndi imfa ya wodwala.

Parathyroid timadzi, zotsatira zawo pa thupi ndi zofunika kwambiri. Nthawi kuzindikira mavuto kugwirizana ndi ntchito ya chithokomiro ndi parathyroid zopangitsa, kuthandiza mayeso njira zoona matenda. Ngati ndi kotheka, dokotala mankhwala ultrasound. Ndi kafukufuku amenewa kuzindikira vutolo nthawi katswiri sikovuta.
