QHOV CHAW UA HAUJ LWM ua rau tag nrho UNICELLULAR EXOCRINE GLANDS tsim? Tag nrho cov unicellular exocrine qog secrete protein mucin (uas ua hnoos qeev ntawm kev sib tov nrog dej).
Ib yam nkaus, dab tsi ua rau cov qog nqaij hlav exocrine tsis sib xws?
Exocrine qog secrete lawv cov khoom mus rau ntawm daim tawv nqaij lossis hauv lub cev kab noj hniav. Unicellular exocrine qog ua Qhov no ncaj qha los ntawm exocytosis, thaum multicellular qog thauj lawv cov khoom los ntawm cov kav dej ntawm qhov chaw epithelial. Khoom zais cia los ntawm exocrine qog suav nrog hws, roj, mucous, kua tsib, thiab lwm yam.
Ib yam li ntawd, qhov tseeb ntawm unicellular exocrine qog yog dab tsi? Unicellular exocrine qog suav nrog ib lub xov tooj tshwj xeeb tshwj xeeb rau kev zais cia tawg ntawm lwm qhov tsis-secretory epithelial cells ntawm daim nyias nyias. Lawv tsis muaj ducts, tau kawg, tab sis lawv zais lawv cov khoom ncaj qha rau ntawm qhov chaw dawb ntawm qhib lub cev kab noj hniav thiab yog li, raug txiav txim siab. ua exocrine.
Tsis tas li ntawd, cov qog nqaij hlav qog ua dab tsi?
A qog yog ib pab pawg hlwb hauv tus tsiaj lub cev uas tsim cov tshuaj (xws li cov tshuaj hormones) tso rau hauv cov ntshav (endocrine) qog ) lossis nkag mus rau kab noj hniav hauv lub cev lossis nws sab nrauv (exocrine qog ).
Yuav ua li cas yog multicellular exocrine qog cais?
Multicellular exocrine qog yog cais los ntawm lawv cov duab ntawm secretory qhov chaw thiab los ntawm kev npaj ntawm lawv ducts. A qog nrog ib lub duct yog "yooj yim," whereas a qog nrog ib tug branched duct yog "compound" qog.

Puas yog tag nrho cov qog nqaij hlav qog noj ntshav?
Osteosarcoma thiab Ewing's sarcoma, ob qho ntawm cov qog nqaij hlav uas tsis zoo tshaj plaws, feem ntau pom muaj nyob hauv tib neeg hnub nyoog 30 lossis qis dua. Hauv kev sib piv, chondrosarcoma, cov qog ua qog uas loj hlob zoo li cov pob txha mos, feem ntau tshwm sim tom qab hnub nyoog 30. Cov qog nqaij hlav qog nqaij hlav muaj xws li: Chondrosarcoma
Dab tsi yog qhov txawv ntawm cov qog endocrine thiab cov qog exocrine?
Dab tsi yog qhov sib txawv ntawm cov qog endocrine thiab exocrine? Lub qog endocrine zais nws cov khoom, piv txwv li cov tshuaj hormones, ncaj qha rau hauv cov ntshav. Lub qog exocrine zais nws cov khoom piv txwv li cov enzymes, rau hauv cov ducts uas ua rau cov nqaij mos
Dab tsi yog cov piv txwv ntawm cov qog endocrine thiab cov qog exocrine hauv tib neeg lub cev?
Piv txwv ntawm cov qog exocrine muaj xws li hws, salivary, mammary, ceruminous, lacrimal, sebaceous, thiab mucous. Exocrine qog yog ib qho ntawm ob hom qog nqaij hlav hauv tib neeg lub cev, lwm qhov yog cov qog endocrine, uas tso lawv cov khoom ncaj qha rau hauv cov hlab ntsha
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Puas yog tag nrho cov qog hauv caj dab mob qog noj ntshav?
Cov caj dab los yog pawg tuaj yeem loj thiab pom tau, lossis lawv tuaj yeem ua rau me me. Feem ntau cov caj dab pob ntseg tsis muaj teeb meem. Feem ntau kuj yog benign, los yog noncancerous. Tab sis pob caj dab kuj tseem tuaj yeem yog ib qho cim ntawm mob hnyav, xws li kis mob lossis mob qog noj ntshav loj hlob
