Qanjirka thymus - immunogenesis dawlad dhexe

xubnaha hormoonada - waa qanjidhada hormoonada jidhka oo aan laga shido excretory, waxa ugu muhiimsan oo iyaga ka mid yihiin: qanjirka pineal, qanjidhada adrenal, qanjirka pituitary, qanjidhada parathyroid, iyo sidoo kale galmada iyo xammeetida. Intaa waxaa dheer, waxaa jira bir ah, isku formation of hormoonnada hawlo kale hormoonada aan, waxaa ka mid ah hypothalamus ah, beeryarada, ugxan, mandheerta iyo thymus. Sidoo kale, marka lagu daro nidaamka hormoonada jidhka ah, awood u leh inay qarsan hormoonnada dhiiga, iyo xubnaha kale waa: qanjidhada dhareerka, qanjirka lacunar, kelyaha, beerka, caloosha iyo mindhicirrada.

Thymus, sidoo kale loo yaqaan thymus ama thymus, waa immunogenesis ah xubin maamulaha. Hawshoodu ugu weyn waa in nidaaminaya dhismaha iyo shaqada nidaamka difaaca jirka. Waxaa halkan waa in isbadal unugyada asliga hematopoietic galay T-limfosaytis.

qanjirka thymus wuxuu ku yaalaa ka dambeeya sternum ee xabadka sare, kor ku xusan waxay xidhmada vascular waxyaalaha qalbiga ku jira. Waxay leedahay laba dhafoorka dhisnayd sinnayn, daboolay by a kaabsal connective khafiif ah oo ka kooban walax cortical iyo cerebral. Saamiyada qanjirka thymus waa kala duwan yihiin baaxadda, waxaa jira xaalado marka birta lahaa share dhexe. qanjirka Fabric ka mid ah epitelioretikulotsitov mnogootrostchatyh taas oo samaysa saddex shabakad cabbir la limfosaytis dhacaan oo siddooyinkuna.

Markaasaa Ananiyas tegey thymus ku dhacdaa on bishii labaad ee uurka, iyo dhalashada qanjirka uu leeyahay size ugu badnaan ee la xiriirta aagga guud ee dusha sare ee jirka aadanaha. Sida ay weynaadaan ratio this hoos u da'da iyo waxa ku dhowaad si buuxda loo atrophied, iyo dhammaan unugyada ay functional waxaa lagu bedelaa unugyada dufanka leh. halbowlayaasha badan oo in soo jeedaan halbowleyaasha thoracic oo liita gudaha thyroid, oo dhiigga qanjirka thymus ku siiyo. socodka xididka Its galay feeraha iyo brachiocephalic xididka ugu hooseeyey, innervation dabacsanaadaan qaadeen saasuu geedcanab iyo dareemayaasha vagus.

Hababka ugu kalsoonaan karo oo wargelin ah ogaanshaha ka mid ah difaaca iyo baaritaan cytological, iyo sidoo kale hababka X-ray.

Haddii ay dhacdo in thymus waa curyaanimo sida aplasia iyo hypoplasia, waxaa jira ifafaale of hoos, kaas oo la Ulasocto calaamadaha Iscelin af badan ee habka difaaca jirka, iyo cudur mindhicireed barar soo noqnoqonaysa, iyo neef-mareenka. ifafaale Kuwani waa mid aad inta badan sababta dhimashada bukaanada. Sidaa darteed, haddii carruurta yaryar, cudur mindhicireed barar soo noqnoqonaysa, iyo neef-mareenka waa in ay daruuri tahay in la bartay thymus functional si looga hortago in la kordhiyo qanjirka thymus ee carruurta. Cilad-kororka this ayaa suuragal ah keliya iyadoo la kaashanayo waxbarashada X-ray. The calaamad weyn ee shucaaca ah ee joogitaanka sii kordhaya thymus yahay ogaanshaha ee astaan u gaar ah, loo yaqaan columnar ama wadnaha, malana, marka hooska sii korodhsan doonaa size qanjirka thymus ku biiro hooska waxyaalaha qalbiga ku jira, abuurista sawir caadi ah oo hoosku.

Calaamadaha ugu muhiimsan ee qanjirka thymus waa: in la kordhiyo inta badan qanjidhada, qumanka, adenoids, thymus, aan caadi ahayn koritaanka (barakacyo hip, syndactyly, Sheelada), hypotension, maqaarka marmar ah, rabshooyin garaaca wadnaha, hyperhidrosis, cayilka.

Daaweynta xaaladaha sababa cillad ah qanjirka thymus, waa ay ka saarida (thymectomy), Cuntada iyo therapy, daroogada tuubooyinka. Haddii kelyaha thymic jira ma laha daliilka caafimaad ee ka-qabashada caafimaad firfircoon ayaa loo baahan yahay.
