Merocrine qog muaj peb lub luag haujlwm tseem ceeb: Thermoregulation. Cov hws ua kom txias ntawm daim tawv nqaij thiab txo lub cev kub. Qhov txias txias no yog lub luag haujlwm tseem ceeb ntawm kev hnov ntxhiab tsw, thiab qib ntawm secretory kev ua si yog tswj los ntawm neural thiab hormonal mechanisms.
merocrine secretion ua dab tsi?
Merocrine qog, xws li qog qaub ncaug, qog nqaij hlav, thiab cov qog hws eccrine, muaj cov cell secretory uas tawm cov khoom los ntawm exocytosis (rau hauv cov kab mob epithelial-walled ducts thiab tom qab ntawd rau lumen) tsis ua rau muaj kev puas tsuaj lossis poob hauv lub cell secretory.
Yuav ua li cas thaum lub zais zis tawm hauv lub qog merocrine?
Merocrine glands secrete khoom los ntawm exocytosis ntawm secretory vacuoles. Tsis muaj ib feem ntawm cov cell ploj hauv cov txheej txheem. Cov cheeb tsam apical (=deb ntawm lub hauv paus membrane sab) ntawm cov hlwb hauv cov qog apocrine tau pinched tawm raws li kev tso tawm, yog li cov hlwb ib nrab poob cytoplasm thaum lub sijhawm tso tawm.
merocrine caj pas hauv biology yog dab tsi?
Merocrine (los yog eccrine) yog ib lo lus siv los faib cov qog exocrine thiab lawv cov secretions hauv kev kawm txog histology. Ib lub xovtooj ntawm tes raug cais raws li merocrine yog tias cov khoom zais ntawm lub xovtooj ntawm tes raug tso tawm ntawm exocytosis los ntawm cov cell secretory mus rau hauv cov kab mob epithelial-walled ducts lossis ducts thiab tom qab ntawd mus rau ntawm lub cev los yog mus rau hauv lumen.
Dab tsi yog qhov txawv ntawm merocrine qog vs apocrineqog?
Qhov txawv ntawm merocrine thiab apocrine hws qog yog qhov merocrine hws qog tawm hws ncaj qha mus rau ntawm daim tawv nqaij qhib tawm los ntawm hws pore thaum apocrine hws qog tso tawm hws mus rau hauv pilary kwj dej ntawm cov plaub hau tsis qhib ncaj qha rau ntawm daim tawv nqaij.
