Muyeso maselo: mbali structural, mungachite maina ndi malo kutanthauzira

Thupi la munthu - ndi miyandamiyanda ya maselo a mosiyanasiyana, mitundu ndi makulidwe. Iwo ali ang'onoang'ono kwambiri motero kuti tione ndi kukaziyesa yekha pansi simungathe kutiona. Ndipotu, maselo - ndi tosaoneka nyumba zidutswa za akalowa minofu, ziwalo, machitidwe ndi lonse chamoyo. Ngakhale kusiyana mitundu maselo onse ndi chithunzi ambiri dongosolo la. Iwo zigwirizana Kakhungu akunja, phata chapakati ndi cytoplasm semiliquid. Za mitundu yosiyanasiyana ya maselo kungakhale nkhani yaitali, koma m'nkhani ino tikambirana mtundu umodzi wokha, wotchedwa maselo muyeso. Tidzayensa kumvetsa chomwe iwo ali, kumene zili ndi momwe ntchito.

Zosintha Title

maselo amenewa amadziwika pansi maina angapo. mawu akuti "enterocyte muyeso", "muyeso ekzokrinotsid" ndi "muyeso grandulotsit" amagwiritsidwa ntchito. maselo muyeso Latin otchedwa enterocytus caliciformis. Nthawi zina akuti "selo zipanda," amene amatanthauza maselo muyeso. Onse oterewa ali ofanana ndi mzake ndi ntchito ngati ofanana.

dzina potengera mawonekedwe zachilendo kwa maselo. Iwo amayang'ana ngati wamtali, yopapatiza galasi pang'ono mudakhumudwapo oposa.

Maselo a mtundu uli ku epithelium wa nembanemba wa mucous ndi zikugwira ntchito yopanga ntchofu. Iwo ali pano mu thupi onse anthu ndi zinyama.

Kutanthauzira. matumbo

maselo muyeso ndi mbali ziwalo angapo zaminyewa. Amodzi mwa malo a kutanthauzira - matumbo. matumbo epithelium ali ndi dongosolo m'malo ovuta. Chili mitundu yambiri ya enterocytes, kuphatikizapo limbic, muyeso, acidophilus, beskaemchatye, endocrine, ndi zina bwino kusiyanitsidwa. Onsewo ali wosakwatiwa tating'ono zopangitsa zimagwira ntchito zosiyanasiyana. Mwachitsanzo, limbic maselo zaminyewa nawo parietal chimbudzi ndi mayamwidwe. Muyeso udindo yopanga ntchofu (onani m'munsimu nkhani zambiri). maselo Endocrine kutulutsa mahomoni thirakiti, acidophilus maselo Punnett kubala kwambiri m'mimba michere. Ntchito undifferentiated maselo - kusinthika kwa epithelium lapansi.

maselo muyeso wa intestine ndi anayikidwa pa villi matumbo. Nyumbazi zimamangidwa mofanana pakati pa maselo limbic. Pa mbali apical wa villi ndi zamkati tubular wa Kakhungu mucous, wotchedwa zopangitsa liberkyunovymi kapena crypts matumbo, maselo muyeso sapezeka. Ngakhale pali chosowa kuchotserapo.

Mu intestine ka mtundu wa maselo zikuluzikulu. 9,5% enterocytes - muyeso zaminyewa maselo. Komanso, chiwerengero chawo chinawonjezeka kwa m'matumbo wapotalikira. Iwo uniformly anagawira pamwamba pa m'munsi mwa crypts ndi villi, ang'onoang'ono kwawo pa villi okha.

Airways

Malo ena kutanthauzira muyeso maselo exocrine - mundawo kupuma. Pano ku maselo amenewa ndi pafupifupi 30% ya epithelium lapansi. maselo ndi analinganiza singly. Iwo ali vacuoles wodzazidwa ndi katulutsidwe mucous. Vacuoles kuwonjezera gawo apical. Khosi gawo la selo limapangidwa ndi Golgi zovuta mitochondria ambiri. Airway muyeso microvilli selo amaperekedwa, amene pambuyo ntchofu kukhala noticeable.

ntchofu ndi cyclical mu chilengedwe zomwe zimadalira zinthu zina, mwachitsanzo kutentha ndi chinyezi.

maselo Conjunctival muyeso

Malo otsatira a kutanthauzira maselo muyeso - maso conjunctiva. The mucosa conjunctival zambiri. Chinsinsi, tochoka ndi maselo amenewa ndi osiyana ndi ntchofu tochoka mu epithelium ziwalo zina. Conjunctival muyeso maselo ili pa wosanjikiza woyambira ndipo chowulungika ndi chingelengele. Ntchofu, amene iwo lithe ndi secrete womangidwa mu mtundu wa maukonde limene likuthandiza ndi nkhani matupi ena ndi mabakiteriya. Pa zikuthwanima, maukonde wasweka ndi ankatembenukira m'mphepete medial, kuchotsa maso kwa zinyalala ndi mabakiteriya.

maselo muyeso mu kapamba

maselo muyeso alipo mu kubwereketsa ducts a kapamba. Iwo ili pa kutalika lonse la ritsa, ndi gawo lawo linafalitsidwa kwambiri. Pali exocrine England anapanga mucosa.

Parotid England

The malovu England ndi olemera maselo muyeso. Iwo zili pafupi pakamwa ndi secrete ntchofu, kuthekera kupulumutsa mankhwala kumulepheretsa tizilomboto. Ndi zaka, chiwerengero cha maselo muyeso mu zopangitsa ndi malovu yafupika. Antimicrobial chotchinga imafoola.

Werengani zambiri za mbali

maselo muyeso kubala ntchofu insoluble wotchedwa mucin. Mucin kumalumikiza mucosa, nthawi zina kudziunjikira ndi makulidwe a 1.5 mm. Kupanga izo, mutsitogennye granules kuyamwa madzi ndi pathupi. Ntchofu maselo muyeso ali ntchito zingapo. Mmimba, kapamba ndi intestine mucosa moisturizes kuti matupi amalimbikitsa muzituluka ndi nkhani matumbo ndi mbali ya khoma chimbudzi. The conjunctiva kupatula humidification ali ndi ntchito zoteteza zopangitsa ndi malovu - chotchinga.

Chitetezo muyeso maselo

Bwinobwino chitetezo ku muyeso maselo ndi kwina magazi. Ngati kusanthula magazi kuchokera mu mtsempha wa kuzindikiridwa chitetezo izi zikutanthauza kuti wodwalayo anam'peza matenda a m'matumbo. Choncho, kwa chitetezo muyeso kusanthula selo Kwalamulidwa kwa masiyanidwe matenda a aakulu matenda yotupa matumbo.
