Qhov sib txawv tseem ceeb ntawm exteroceptors thiab interoceptors yog cov exteroceptors ntes stimuli los ntawm sab nraud ntawm lub cev thiab xa cov ntaub ntawv hais txog lub sab nraud ib puag ncig, thaum interoceptors tau txais stimuli los ntawm cov kab mob hauv nruab nrog cev (viscera) thiab cov hlab ntsha thiab xa cov ntaub ntawv hais txog sab hauv. lub xeev ntawm lub cev mus rau lub hauv paus paj hlwb.
Sensory receptors teb rau cov kev hloov pauv tshwm sim nyob ib puag ncig lawv. Hauv lwm lo lus, sensory receptors muaj peev xwm paub qhov kev hloov pauv hauv lawv ib puag ncig. Lawv activation ua rau paj hlwb impulses. Raws li qhov chaw stimulus ntawm receptors, muaj peb lub ntsiab ntawm receptors li exteroceptors, interoceptors, thiab proprioceptors. Exteroceptors nyob ze ntawm daim tawv nqaij, thiab lawv teb rau stimuli los ntawm sab nraud ntawm lub cev. Interoceptors yog nyob rau hauv lub cev, thiab lawv teb rau stimuli los ntawm sab hauv viscera thiab cov hlab ntsha. Proprioceptors teb rau cov kev txav los ntawm cov leeg nqaij, leeg, thiab cov leeg pob txha thiab kev ntxhov siab.
Exteroceptors yog dab tsi?
Exteroceptors yog cov receptors sensory uas ntes cov stimuli los ntawm sab nraud ntawm lub cev. Lawv tau tshwj xeeb los saib xyuas qhov chaw sab nraud ntawm lub cev. Raws li txoj cai, lawv yog cov paj hlwb afferent kawg (axons ntawm sensory neurons). Lawv muaj nyob ze rau ntawm daim tawv nqaij thiab kho qhov muag pom, suab, hnov tsw, thiab cov tsos mob ntawm daim tawv nqaij xws li kov, mob, vibration, kub, khaus, thiab tickling. Ib zaug tom qab tau txais kev txhawb nqa sab nraud, tus exteroceptor hloov nws mus rau cov hlab ntsha impulse thiab xa mus rau hauv nruab nrab lub paj hlwb thiaj li ua tiav thiab xa mus rau hauv cov nyhuv.
Daim duab 01: Mechanoreceptor
Mechanoreceptors yog ib hom exteroceptors tshwj xeeb rau kev nkag siab txog kev siv tshuab xws li kov, siab, ncab, thiab kev co, thiab lwm yam. Thermoreceptors yog lwm hom exteroceptors uas tshwj xeeb rau kev hloov pauv kub.
Dab tsi yog Interoceptors?
Interoceptors yog cov rhiab receptors uas ntes cov stimuli los ntawm cov kabmob sab hauv thiab cov hlab ntsha. Yog li ntawd, lawv teb rau stimuli tshwm sim hauv lub cev. Lawv sib sib zog nqus nyob rau hauv lub cev nyob rau hauv lub viscera. Visceroceptors yog lwm lub npe ntawm interoceptors. Interoceptors xa cov ntaub ntawv mus rau hauv nruab nrab lub paj hlwb txog lub xeev ntawm lub cev. Yog li, cov receptors no saib xyuas viscera, tshwj xeeb tshaj yog cov hlab plawv, plab zom mov, kev ua me nyuam, ua pa, thiab tso zis.
Daim duab 02: Interoception
Nrog ntau hom interoceptors, chemoreceptors, nociceptors, thiab stretch receptors yog peb hom. Lub cev carotid yog chemoreceptor uas kuaj pom CO2 qib hauv cov ntshav thiab xa cov ntaub ntawv mus rau CNS. Stretch receptors, ntawm qhov tod tes, kuaj pom cov hlab ntsha siab.
Dab tsi yog qhov zoo sib xws ntawm Exteroceptors thiab Interoceptors?
- Exteroceptors thiab interoceptors yog ob hom kev hnov qab pom hauv peb lub cev.
- Lawv koom nrog lub paj hlwb peripheral.
- Lawv tuaj yeem teb rau qhov stimuli thiab xa cov ntaub ntawv mus rau hauv nruab nrab lub paj hlwb.
- Cov receptors no muaj peev xwm hloov stimuli rau hauv paj hlwb impulses.
- Lawv yog cov hloov pauv.
Qhov txawv ntawm Exteroceptors thiab Interoceptors yog dab tsi?
Exteroceptors yog cov rhiab receptors uas teb rau stimuli los ntawm sab nraud ntawm lub cev. Nyob rau hauv sib piv, interoceptors yog cov sensory receptors uas teb rau stimuli tshwm sim nyob rau hauv lub cev los ntawm lub cev thiab cov hlab ntsha. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm exteroceptors thiab interoceptors. Exteroceptors saib xyuas qhov chaw sab nraud, thaum interoceptors saib xyuas qhov chaw sab hauv. Qhov no yog lwm qhov sib txawv ntawm exteroceptors thiab interoceptors.
Ntxiv mus, exteroceptors nyob ze ntawm qhov chaw ntawm lub cev, thaum interoceptors nyob tob hauv lub cev, nyob rau hauv lub viscera. Exteroceptors feem ntau yog kov, hnov tsw, kub, mob, suab, kev co, thiab lwm yam, thaum interoceptors kuaj ntshav siab, ntshav oxygen, ntshav CO2 qib, thiab lwm yam.
Daim duab hauv qab no nthuav tawm qhov sib txawv ntawm exteroceptors thiab interoceptors nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Exteroceptors vs Interoceptors
Sensory receptors teb rau stimuli. Exteroceptors thiab interoceptors yog ob ntawm peb hom tseem ceeb ntawm kev hnov lus receptors. Exteroceptors teb rau stimuli tshwm sim los ntawm sab nraud ntawm lub cev, thaum interoceptors teb rau stimuli los ntawm lub cev los yog viscera (hauv lub cev). Exteroceptors pom nyob ze ntawm lub cev, thaum interoceptors pom tob hauv lub cev. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm exteroceptors thiab interoceptors.
