Equilibrium . Lub vestibule nyob nruab nrab ntawm cov kwj dej semicircular thiab cochlea. Nws muaj ob lub bulblike sacs, lub saccule thiab utricle, uas nws daim nyias nyias yog tas li nrog cov cochlea thiab semicircular kwj dej, feem. Lub saccule thiab utricle muaj cov receptors uas pab tswj kev sib npaug.
Thiaj li, hom neeg txais khoom twg yog qhov sib npaug?
Cov kwj dej semicircular, lub utricle, thiab lub pob ntseg ntawm lub pob ntseg yog koom nrog. kev sib npaug . Ob leeg hnov thiab kev sib npaug vam khom tshwj xeeb heev hom receptor hu ua plaub hau cell.
Ib tus kuj tseem yuav nug, qhov twg yog cov neeg txais khoom sib npaug nyob ntawm qhov lus nug? Hauv cov kwj dej semicircular thiab hauv vestibule ntawm pob ntseg.
Tom qab, lo lus nug yog, qhov sib npaug receptors nyob qhov twg?
Equilibrium receptors yog nyob nyob rau hauv ib feem ntawm sab hauv pob ntseg hu ua labyrinth.
Lub luag haujlwm ntawm equilibrium yog dab tsi?
Physiology ntawm kev tshuav: vestibular muaj nuj nqi. Lub vestibular system yog lub sensory apparatus ntawm lub pob ntseg sab hauv uas pab cov lub cev tuav nws postural equilibrium. Cov ntaub ntawv muab los ntawm cov kab ke vestibular tseem yog qhov tseem ceeb rau kev tswj hwm txoj haujlwm ntawm lub taub hau thiab kev txav ntawm lub qhov muag.

Dab tsi yog visceral receptors?
Visceral receptors feem ntau yog pub dawb cov hlab ntsha kawg (txawm hais tias Pacinian corpuscles muaj nyob hauv viscera). Kev hnov qab lub ntsej muag suav nrog qib kev puv thiab mob, qhov kawg yog feem ntau raug mob vim tias visceral thiab somatic afferent neurons feem ntau faib cov neurons
Peb hom cutaneous receptors yog dab tsi?
Cov cutaneous receptors 'yog hom kev hnov lus pom muaj nyob hauv dermis lossis epidermis. Lawv yog ib feem ntawm somatosensory system. Cov tawv nqaij txais cov tawv nqaij suav nrog txiav cov neeg kho tshuab lub cev, nociceptors (mob) thiab thermoreceptors (kub)
Dab tsi yog qhov ua haujlwm ntawm cov hlab ntsha receptors?
Tus neeg txais kev nkag siab yog tus qauv uas cuam tshuam rau lub cev kev txhawb nqa hauv ib puag ncig, tsis hais sab hauv lossis sab nraud. Nws yog qhov kawg ntawm lub paj hlwb uas tau txais cov ntaub ntawv thiab ua cov txheej txheem ntawm kev tsim cov paj hlwb kom xa mus rau lub hlwb rau kev txhais lus thiab kev nkag siab
Dab tsi yog qhov txawv ntawm metabotropic thiab ionotropic receptors?
Ionotropic thiab metabotropic receptors yog ob leeg ligand-gated transmembrane proteins. Ionotropic receptors hloov cov duab thaum lawv raug khi los ntawm ligand. Qhov kev hloov pauv hauv cov duab no tsim cov channel uas tso cai rau ions ntws los ntawm. Metabotropic receptors tsis muaj cov channel
Plaub receptors ntawm daim tawv nqaij yog dab tsi?
Cov txheej txheem no yog lub luag haujlwm rau txhua qhov kev xav uas peb xav tau - txias, kub, du, ntxhib, siab, zuam, khaus, mob, vibrations, thiab ntau dua. Nyob rau hauv lub somatosensory system, muaj plaub lub ntsiab receptors: mechanoreceptors, thermoreceptors, mob receptors, thiab proprioceptors
