Puas mob receptors tsis muaj paj hlwb xaus?
Pain Receptors tseem hu ua free paj endings. Cov receptors yooj yim no muaj nyob rau hauv cov dermis nyob ib ncig ntawm lub hauv paus ntawm cov hauv paus plaub hau thiab ze rau ntawm daim tawv nqaij (epidermis) qhov twg cov plaub hau tawm ntawm daim tawv nqaij.
Yuav ua li cas cov paj dawb xaus pom qhov mob?
Nociceptors Tsim Kev Mob Ua Ntej thiab Thib ObPab dawb cov paj hlwb hu ua nociceptors hauv daim tawv nqaij muaj qhov pib siab rau kev siv tshuab, tshuaj, lossis thermal stimuli thiab teb tsuas yog thaum qhov kev siv ntawm cov stimuli no siab txaus ua rau cov nqaij mos puas. Peb pom cov tswv yim los ntawm cov receptors no ua mob.
Pob paj hlwb tsis muaj qhov kawg pom qhov siab?
qauv. Cov paj hlwb pub dawb tuaj yeem kuaj xyuas qhov kub thiab txias, txhua yam stimuli (kov, siab, ncab) lossis txaus ntshai (nociception). Yog li, cov paj hlwb sib txawv ua haujlwm raws li cov thermoreceptors, cutaneous mechanoreceptors thiab nociceptors.
Dab tsi yog cov haujlwm ntawm cov hlab ntsha xaus?
Koj cov hlab ntsha xaus yog ntau lab lub ntsiab lus ntawm koj lub cev thiab sab hauv uas xa lus rau koj lub hlwb thaum koj hnov zoo li cua sov, txias, thiab mob.

A neurosurgeon muaj peev xwm ua kev phais ntawm lub hlwb thiab tus txha caj qaum, qhov uas tus kws kho mob hlwb feem ntau ua tsis tau. Ntxiv nrog rau kev ua cov txheej txheem phais, cov kws kho mob neurosurgeons tseem tuaj yeem pab koj taug qab koj qhov kev kuaj mob, koj txoj kev npaj kho mob, qhov kev phais tiag tiag, thiab kev xaiv tom qab rov zoo .
Kev mob hlwb hauv kev kho mob hlwb?
Ischaemic strokes feem ntau tuaj yeem kho tau los ntawm kev txhaj tshuaj tshuaj hu ua alteplase, uas ua rau cov ntshav txhaws thiab rov ua kom cov ntshav ntws mus rau lub hlwb. Qhov kev siv tshuaj "clot-busting" no hu ua thrombolysis .
Puas tuaj yeem kuaj pom tus kab mob leukemia hauv kev kuaj ntshav?
kuaj ntshav. Los ntawm kev saib cov qauv ntawm koj cov ntshav, koj tus kws kho mob tuaj yeem txiav txim siab yog tias koj muaj qhov txawv txav ntawm cov qe ntshav liab lossis cov qe ntshav dawb lossis platelets- uas yuav qhia tau cov kab mob leukemia.
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
Puas yog lub tshuab kuaj kab mob kuaj pom lub teeb pom kev zoo?
Kev faib tawm thiab cov khoom siv lub teeb pom kev sib xyaw yog ob qho tib si optical microscopesuas siv lub teeb pom kev los tsim cov duab. … Qhov tseem ceeb tshaj plaws, kev tshuaj xyuas lub tshuab ntsuas hluav taws xob yog txhawm rau saib cov yam ntxwv saum npoo ntawm tus qauv, qhov sib xyaw microscopes yog tsim los saib los ntawm cov qauv .
