Vim li cas qee tus neeg txais yuav hloov pauv qeeb thiab lwm tus hloov pauv sai ? Ceev ceev kev hloov kho ceeb toom koj yog tias muaj yog kev hloov pauv ntawm qhov kev txhawb siab, zoo li qhov pib ntawm kov. Lawv yog rhiab heev rau cov kev hloov me me vim lawv tua hluav taws sai sai . Qeeb yoog raws hluav taws qeeb, thiab yog feem ntau koom nrog kev nkag siab zoo li qub (piv txwv li tuav ib qho khoom).
Xav txog qhov no, dab tsi yog adapting receptors hu ua sai?
Hloov kho sai : Hloov kho sai mechanoreceptors suav nrog Meissner lub cev kawg lub cev, Pacinian corpuscle kawg lub cev, cov hauv paus plaub hau cov receptors thiab qee qhov kawg ntawm lub paj dawb.
Kuj Paub, uas somatic sensory receptors hloov maj mam thiab qhov twg yoog sai? Ceev ceev kev yoog raws txhais tau tias cov tus txais yuav teb sai sai, tab sis yuav tsis muab cov lus teb ruaj khov. Ob lub mechanoreceptors muaj qhov chaw txais me me: merkel's discs thiab meissner's corpuscles. Merkel cov discs teb maj mam , thiab meissner lub cev tuag teb sai.
Hais txog qhov no, dab tsi yog qhov sib txawv ntawm kev hloov pauv sai thiab maj mam hloov pauv tus txais?
Maj mam hloov kho cov neeg kho tshuab txuas ntxiv teb rau qhov stimulus, whereas sai adapting receptors teb tsuas yog thaum pib (thiab feem ntau qhov offset) ntawm stimulation. Cov kev ua haujlwm no sib txawv tso cai rau cov kws kho tsheb muab cov ntaub ntawv hais txog (ntxiv)
Cov neeg txais khoom sib txawv hauv lawv lub peev xwm los hloov?
Receptors yuav txawv ntawm lawv lub peev xwm los hloov rau. Qhov kev saib ua ntej no qhia txog nplooj 5 - 8 ntawm 13 nplooj ntawv. Kev Hloov: A kev xav tus txais yuav tsum teb rau cov stimulus thiab hloov nws mus rau hauv qhov hu ua ib receptor los yog generator muaj peev xwm. Txhua tus txais muaj a tshwj xeeb mechanism rau kev tsim khoom ib receptor peev xwm.

Cov neeg txais khoom twg yoog sai?
Ceev nrooj hloov kho: Hloov kho tus neeg kho tshuab nrawm suav nrog Meissner lub cev qhov kawg ntawm lub cev, Pacinian lub cev qhov kawg ntawm lub cev, cov hauv paus plaub hau tau txais thiab qee qhov kawg ntawm lub paj dawb
Qhov twg yog tus kab mob sib deev ntau tshaj plaws uas yog tshwm sim los ntawm cov kab mob thiab qee zaum ua rau mob tso zis hauv tus txiv neej?
Epididymitis feem ntau tshwm sim los ntawm kev kis kab mob, suav nrog kev sib deev sib kis (STIs), xws li tus kab mob gonorrhea lossis chlamydia
Vim li cas cov hlwb hloov pauv hloov lawv cov duab?
Cov hlwb no hu ua kev hloov pauv vim lawv tuaj yeem hloov pauv hauv lawv cov duab thiab cov qauv. Tsis tas li ntawd, cov hlwb yog stratified, uas txhais tau hais tias lawv tsim ob peb txheej. Cov stratified cells ntawm kev hloov pauv epithelium muab kev tiv thaiv thiab tso cai rau cov hlab ntsha nthuav dav kom haum rau cov kua
Vim li cas qee cov neeg xaiv los hloov lawv lub siab?
Ntau yam kab mob tuaj yeem ua rau lub xeev tsis nco qab, xws li cov uas ua rau pw tsaug zog lossis oxygen deprivation.

Dab tsi yog qee txoj hauv kev uas tus kws pab kho hniav tuaj yeem pab ua kom lub qhov ncauj qhuav li sai tau thaum cov txheej txheem kho hniav?
Cov txheej txheem ib txwm uas siv cov txheej txheem tswj hwm kev kho hniav suav nrog kev tu hniav, sau ua ke, sib sau ua ke thiab cov hauv paus hniav. Cov txheej txheem tswj kev ya raws sib txawv suav nrog cov txheej txheem tshem tawm qhov ncauj, yaug qhov ncauj kab noj hniav, thiab cais cov hniav
