Serous vs Mucus
Serous thiab mucus yog ob hom kua uas tsim los ntawm cov qog exocrine. Lawv raug tso tawm ncaj qha mus rau sab nraud ntawm cov qog los ntawm cov ducts. Cov kua dej no muaj qhov sib txawv ntawm lub cev nrog rau lawv cov keeb kwm, muaj pes tsawg leeg, feem pua dej thiab lwm yam. Txawm li cas los xij, ob qho tib si serous thiab mucus yog ib qho tseem ceeb hauv kev muab kev tiv thaiv rau cov txheej txheem ntawm tes thiab lub cev.
Mus
Mucus yog viscoelastic, nonhomogenous kua uas muaj dej matrix, glycoproteins, proteins, thiab lipids. Mucus yog tsim los ntawm mucous hlwb, uas zoo li ua mucous daim nyias nyias thiab mucous qog. Cov mucous daim nyias nyias tuaj yeem pom hauv ob sab phlu ntawm lub ntsws, digestive system, reproductive system, thiab urinary system. Lo lus 'mucosa' yog siv los txheeb xyuas cov mucous tshwj xeeb. Piv txwv li, ua pa mucosa kab kab mob ua pa, kab mob plab kab mob hauv plab, thiab plab hnyuv mucosa kab cov hnyuv me thiab loj. Mucus ua hauj lwm raws li ib tug lubricant thiab tiv thaiv cell txheej nyob rau hauv lub cev. Tsis tas li ntawd, nws pab tshem cov kab mob thiab lwm yam khoom txawv teb chaws los ntawm lub cev.
Serous
Serous yog cov kua dej uas feem ntau muaj dej thiab qee cov proteins xws li amylase enzyme. Nws yog tsim los ntawm serous hlwb, uas yog teem raws li pawg hu ua 'acini' nyob rau hauv serous qog. Cov qog ntshav muaj nyob hauv cov qog parotid thiab cov qog lacrimal. Serous kuj tuaj yeem tsim los ntawm cov qog sib xyaw xws li cov qog submaxillary. Cov qog ua kua ua kua ua kua thiab serous. Tsis tas li ntawd, serous tuaj yeem pom nyob rau hauv qhov chaw nruab nrab ntawm lub ntsws thiab pleural sac li 'pleural fluid', nyob rau hauv qhov chaw nruab nrab ntawm lub plawv thiab pericardial sac li 'pericardial kua', thiab nyob rau hauv nruab nrab ntawm txoj hnyuv thiab lub peritoneal sac li 'peritoneal kua. '. Lub luag haujlwm tseem ceeb ntawm serous yog los pab zom cov hmoov txhuv nplej siab, tso cai rau lub cev txav mus los, thiab tiv thaiv kev sib txhuam.
Qhov txawv ntawm Serous thiab Mucus yog dab tsi?
• Mucous cells nyob rau hauv cov qog mucous secrete mucus, thaum serous hlwb nyob rau hauv lub serous qog secrete serous.
• Pawg ntawm cov serous hlwb hu ua serous acini, whereas pawg ntawm mucous hlwb hu ua mucous acini.
• Mucous acini yog tsim los ntawm cov hlwb loj, whereas serous acini yog tsim los ntawm cov hlwb me.
• Serous acini muaj nqaim lumen thaum mucous acini muaj dav lumen.
• Nucleus ntawm serous cell yog spherical thiab muab tso rau hauv lub basal thib peb ntawm cell, whereas ntawm mucous cell yog flattened thiab muab tso rau ze ntawm lub hauv paus.
• Hauv H thiab E- stain, mucous cells tshwm xiav daj, tsis zoo li cov serous cells.
• Lub Golgi cell complex yog kom meej meej tshwm sim nyob rau hauv mucous hlwb, tsis zoo li nyob rau hauv serous hlwb.
• Mucus yog tuab thiab viscous kua, whereas serous yog ntau watery thiab tsawg thicker.
• Serous muaj amylase enzyme, whereas mucus muaj me me los yog tsis muaj enzymes.
• Serous pab zom cov hmoov txhuv nplej siab, qhov hnoos qeev tsuas yog ua cov roj nplua nyeem thiab tiv thaiv txheej.
• Serous yog tawm los ntawm exocytosis los ntawm serous hlwb, whereas mucus yog tso tawm los ntawm rupturing lub mucous membrane.
• Interdigitations ntawm cov mucous uas nyob ib sab yog ob peb, whereas Interdigitations ntawm cov serous cells uas nyob ib sab muaj ntau.
