Goblet hlwb: ntxwv nta, xaiv npe thiab qhov chaw ntawm localization

Cov tib neeg lub cev - yog lub tsheej lab ntawm hlwb ntawm ntau yam nrhiav, hom thiab ntau thiab tsawg. Lawv yog cov me me hais tias lawv xav txog thiab xyuas lawv xwb nyob rau hauv ib tug tshuab kuaj kab mob. Nyob rau hauv qhov tseeb, lub hlwb - yog lub me me lub tsev blocks ntawm ob sab phlu cov ntaub so ntswg, kabmob, tshuab thiab tag nrho kab mob. Dua li ntawm qhov sib txawv nyob rau hauv ntaub ntawv rau tag nrho cov hlwb yog ib tug general daim duab ntawm cov qauv. Lawv muaj xws li ib tug txheej membrane, lub hauv paus keeb thiab cytoplasm semiliquid. Hais txog qhov kev sib txawv ntawm cov hlwb yuav ua tau ib tug ntev tham, tab sis qhov no tsab xov xwm yuav muab suav hais tias tsuas yog ib hom, hu ua Goblet hlwb. Peb yuav sim kom to taub li cas lawv yog, qhov twg yog nyob thiab yuav ua li cas khiav lag luam.

Title xaiv

Tej hlwb paub nyob rau hauv ob peb lub npe. cov kab lus "enterocyte Goblet", "Goblet ekzokrinotsid" thiab "Goblet grandulotsit" yog feem ntau siv. Latin Goblet hlwb hu ua enterocytus caliciformis. Tej zaum lub sij hawm "cell goblets," uas kuj yog hais txog Goblet hlwb. Tag nrho cov ntsiab lus uas sib npaug rau txhua lwm yam thiab siv tau raws li txhais.

Lub npe reflected qhov txawv zoo ntawm lub hlwb. Lawv zoo li ib tug siab, nqaim iav me ntsis flared upwards.

Hlwb ntawm no hom yuav mus rau lub epithelium ntawm lub qog ua kua week thiab yog koom nyob rau hauv zus tau tej cov hnoos qeev. Lawv yog cov tam sim no nyob rau hauv lub cev tib neeg thiab tsiaj.

Localization. hnyuv

Goblet hlwb yog ib feem ntawm ob peb epithelial kabmob. Ib qhov chaw ntawm localization - cov hnyuv. plab hnyuv epithelium muaj ib tug es txoj kev teeb tsa. Nws combines ob peb hom enterocytes, nrog rau cov limbic, Goblet, acidophilus, beskaemchatye, endocrine, thiab lwm yam tsis zoo txawv. Tag nrho cov ntawm lawv yog cov ib leeg-celled qog nrog txawv zog. Piv txwv li, lub limbic epithelial hlwb muab kev koom tes nyob rau hauv parietal zom cov zaub mov thiab haum. Goblet lub luag hauj lwm rau zus tau tej cov hnoos qeev (saib hauv qab no tham ntau). Endocrine hlwb tsim cov tshuaj hormones huam, acidophilus hlwb Punnett tsim ntau digestive enzymes. Muaj nuj nqi undifferentiated hlwb - lwm ntawm lub epithelium.

Goblet hlwb ntawm txoj hnyuv yog muab tso rau hauv plab hnyuv villi. Lawv yog ua nyob rau hauv tib nruab nrab ntawm cov limbic hlwb. Nyob rau apical ib feem ntawm lub villi thiab nyob rau hauv tubular ua si nraum zoov ntawm lub qog ua kua membrane, hu ua liberkyunovymi qog los yog plab hnyuv crypts, Goblet hlwb tsis pom. Txawm hais tias muaj tsawg yam.

Nyob rau hauv cov hnyuv ntawm no hom ntawm hlwb loj. 9.5% enterocytes - Goblet epithelial hlwb. Ntxiv mus, lawv muaj pes tsawg tsub kom ntawm lub distal nyuv. Lawv uniformly faib nyob rau sab saum toj ntawm lub hauv paus ntawm lub crypts thiab villi, lawv me npaum li cas rau lub villi lawv tus kheej.

tej hlab cua txhob

Lwm qhov chaw localization Goblet exocrine hlwb - cov pa ib ntsuj av. Ntawm no nyob rau hauv cov hlwb yog yuav luag 30% ntawm lub epithelium. Lub hlwb kuj txheej txheem singly. Lawv muaj vacuoles uas muaj cov qog ua kua secretion. Vacuoles nyob rau hauv expanding cov apical ib feem. Lub caj dab ntawm lub cell muaj lub Golgi complex thiab ntau mitochondria. Caj pas Goblet cell microvilli yog muab, uas, tom qab hnoos qeev ua hnov li cas.

hnoos qeev yog cyclical nyob rau hauv cov xwm, uas nyob ntawm seb lwm yam, piv txwv li kub thiab humidity.

Conjunctival Goblet hlwb

Cov tom ntej no qhov chaw ntawm localization ntawm Goblet hlwb - cov conjunctiva ob lub qhov muag. Lub conjunctival mucosa ntau ntau. Ntawm daim card, secreted los ntawm cov hlwb yog txawv los ntawm lub hnoos qeev secreted nyob rau hauv lub epithelium ntawm lwm yam kabmob. Conjunctival Goblet hlwb nyob rau ntawm lub basal txheej thiab yog dawb thiab yeej. Hnoos qeev, uas lawv coj los ua ke thiab paim, ua txhua yam nyob rau hauv ib yam ntawm cov network uas captures thiab sau txawv teb chaws lub cev thiab cov kab mob. Thaum lub sij hawm flashing, lub network yog lawm thiab txav mus rau nrub nrab ntug, tshem lub qhov muag los ntawm cov khib nyiab thiab cov kab mob.

Goblet hlwb nyob rau hauv lub pancreas

Goblet hlwb yog tam sim no nyob rau hauv lub qhov hluav taws xob ducts ntawm lub pancreas. Lawv tsis nyob rau hauv tag nrho ntev ntawm lub duct, thiab nyob rau hauv lawv cov widest ib feem. Muaj exocrine caj pas tsim mucosa.

Parotid caj pas

Cov muaj qaub caj pas yog kuj nplua nuj nyob rau hauv Goblet hlwb. Lawv nyob ze lub qhov ncauj thiab paim hnoos qeev, muaj peev xwm xa ib tug tshuaj barrier rau microbes. Nrog lub hnub nyoog, tus xov tooj ntawm Goblet hlwb nyob rau hauv lub muaj qaub ncaug yog txo. Antimicrobial barrier tsis muaj zog txog.

Nyeem ntxiv txog cov yam ntxwv

Goblet hlwb tsim insoluble hnoos qeev uas yog hu ua mucin. Mucin meem mucosa, tej zaum noog mus rau ib tug tuab ntawm 1.5 hli. Yuav kom tsim nws, mutsitogennye granules nqus dej thiab swell. Hnoos qeev ntawm Goblet hlwb muaj ob peb zog. Nyob rau hauv lub plab, pancreas thiab hnyuv mucosa moisturizes nws lub cev yeej txhawb pais plab thiab hnyuv txheem, yog ib feem ntawm cov phab ntsa digestion. Lub conjunctiva tsuas yog humidification muaj ib tug tiv thaiv kev ua nyob rau hauv lub muaj qaub ncaug - barrier.

Tshuaj Goblet hlwb

Feem ntau cov tshuaj rau Goblet hlwb yog tsis tuaj kawm ntawv nyob rau hauv cov ntshav. Yog hais tias tus tsom xam ntawm cov ntshav los ntawm cov hlab ntsha uas pom tias cov tshuaj, nws txhais tau tias tus neeg mob muaj ulcerative mob plab. Yog li ntawd, rau cov tshuaj Goblet cell tsom kws kho rau cov differential mob ntawm tus kab mob inflammatory plob tsis so tswj kab mob.
