Qhov sib txawv tseem ceeb ntawm mechanoreceptors thiab proprioceptors yog tias mechanoreceptors teb rau cov neeg kho tshuab sab nraud thiab tuaj yeem sib txawv hauv lawv qhov kev faib tawm, hos proprioceptors teb rau cov neeg kho tshuab stimuli thiab txwv rau cov pob txha thiab cov leeg.
Receptors yog ntau yam biomolecules feem ntau muaj nyob rau hauv cov ntshav plasma thiab teb rau ntau yam stimuli. Yog li, mechanoreceptors thiab proprioceptors yog ob hom receptors uas teb rau cov neeg kho tshuab stimuli. Lawv qhov kev txiav txim receptor yog kho los ntawm ion gated raws. Yog li ntawd, qhov ua kom ua rau muaj kev cuam tshuam txog kev ntxhov siab.
Mechanoreceptors yog dab tsi?
Mechanoreceptors yog ib pawg ntawm somatosensory receptors. Yog li ntawd, lawv cia siab rau cov teeb liab intracellular transduction mechanism tau txais los ntawm ionotropic raws. Cov stimuli tuaj yeem yog kov, siab, ncab stimuli, suab lossis txav. Cov mechanoreceptors no feem ntau muaj nyob rau hauv daim tawv nqaij ntawm daim tawv nqaij los yog cov khaubncaws sab nraud povtseg ntawm daim tawv nqaij. Txawm li cas los xij, nws kuj tuaj yeem nyob ze cov pob txha. Cov mechanoreceptors no tuaj yeem raug encapsulated lossis un-encapsulated.
Muaj ntau hom mechanoreceptors. Lawv yog Merkel's disks, Meissner's corpuscles, Ruffini xaus, thiab Pacinian corpuscles. Cov mechanoreceptors no qhia ntau yam kev faib tawm. Merkel's disks muaj nyob rau hauv cov lus qhia ntawm cov ntiv tes, sab nraud genitalia, thiab daim di ncauj. Meissner's corpuscles muaj nyob rau hauv lub epidermis ntawm daim tawv nqaij glabrous ntawm tus ntiv tes, xib teg, thiab ib leeg. Lub Ruffini xaus muaj nyob rau hauv daim tawv nqaij sib sib zog nqus, ligaments, thiab tendons, thaum Pacinian corpuscles muaj nyob rau hauv cov ntaub so ntswg subcutaneous ntawm daim tawv nqaij.
Daim duab 01: Mechanoreceptors
Mechanoreceptor muaj nuj nqi nyob ntawm qhov cuam tshuam los ntawm cov receptors thaum ntws ntawm ions. Tom qab ntawd nws yuav qhib lub cim ntawm qhov kev ua haujlwm muaj peev xwm, ua rau lub tshuab hloov pauv thiab pib ntawm cov neeg kho tshuab rog hauv kev teb rau cov stimuli. Cov receptors no feem ntau tshwm sim los ntawm cov hlwb neural crest. Lawv loj hlob thaum lub sij hawm embryonic txoj kev loj hlob thiab undergo tag nrho maturation nyob rau hauv lub post-natal lub sij hawm.
Proprioceptors yog dab tsi?
Proprioceptors yog hom mechano-sensory neurons. Lawv feem ntau muaj nyob rau hauv cov leeg, leeg, thiab pob qij txha. Muaj ntau hom proprioceptors uas tau qhib rau hauv ntau zaus. Nws tuaj yeem yog limb tshaj tawm thiab txav mus los, limb load thiab limb txwv. Qhov no yog hu ua proprioception los yog qhov thib rau kev nkag siab.
Proprioception feem ntau yog kho los ntawm lub hauv paus paj hlwb thiab cov stimuli xws li tsis pom kev thiab vestibular system. Proprioceptors raug faib thoob plaws hauv lub cev. Peb hom proprioceptors yog cov leeg leeg, Golgi leeg nqaij, thiab Golgi tendons.
Daim duab 02: Proprioception
Kev ua kom cov proprioceptors tshwm sim ntawm qhov chaw ib puag ncig. Lawv yog cov paj hlwb tshwj xeeb uas pab txhawb kev ua haujlwm ntawm proprioceptors. Lawv yog cov receptors tshwj xeeb rau siab, lub teeb, kub, suab thiab lwm yam kev xav. Cov receptors no kuj tau kho los ntawm ion gated channels. Cov proprioceptors kuj tsim thaum lub sij hawm embryonic kev loj hlob.
Dab tsi yog qhov zoo sib xws ntawm Mechanoreceptors thiab Proprioceptors?
- Mechanoreceptors thiab proprioceptors yog receptors teb rau cov neeg kho tshuab stimuli.
- Ob leeg yog sib kho los ntawm ion gated channels.
- Lawv pib lub paj hlwb xa mus raws li kev ua kom cov receptor tshwj xeeb.
- Ob leeg tsim thaum lub sij hawm embryonic kev loj hlob.
- Ntxiv mus, lawv muaj cov hlab ntsha xaus uas txhawb nqa lub receptor.
Qhov txawv ntawm Mechanoreceptors thiab Proprioceptors yog dab tsi?
Qhov sib txawv tseem ceeb ntawm mechanoreceptors thiab proprioceptors yog hom stimuli uas lawv teb. Mechanoreceptors teb rau sab nraud stimuli thaum proprioceptors teb rau sab hauv stimuli. Yog li ntawd, kev faib tawm ntawm cov receptors thiab cov subtypes sib txawv kuj txawv ntawm ob hom receptors. Mechanoreceptors muaj nyob rau hauv daim tawv nqaij los yog sib sib zog nqus txheej ntawm daim tawv nqaij thaum proprioceptors pom nyob rau hauv cov leeg nqaij los yog tendons. Yog li, qhov no yog lwm qhov sib txawv ntawm mechanoreceptors thiab proprioceptors.
Merkel's disks, Meissner's corpuscles, Ruffini kawg, thiab Pacinian corpuscles yog cov piv txwv ntawm mechanoreceptors thaum cov leeg nqaij, Golgi leeg nqaij, thiab Golgi tendons yog cov piv txwv rau proprioceptors.
Summary – Mechanoreceptors vs Proprioceptors
Mechanoreceptors yog ib pawg dav ntawm cov receptors uas teb rau cov neeg kho tshuab sab nraud. Proprioceptors yog ib pawg ntawm mechanoreceptors uas txwv rau cov leeg thiab cov leeg. Tsis tas li ntawd, proprioceptors teb rau sab hauv stimuli feem ntau thiab pab txhawb kev txav mus los. Mechanoreceptors tuaj yeem yog Merkel's disks, Meissner's corpuscles, Ruffini kawg lossis Pacinian corpuscles. Lub caij no, Proprioceptors tuaj yeem yog cov leeg leeg, Golgi leeg nqaij lossis Golgi tendons. Yog li, qhov no qhia txog qhov sib txawv ntawm mechanoreceptors thiab proprioceptors.
