Cov hlwb nyuaj kuj tseem yog cov neurons hauv V1 uas teb tau zoo rau qhov kev txhawb nqa nrog kev qhia tshwj xeeb. Tab sis, tsis zoo li yooj yim hlwb , lawv teb rau ntau yam kev txhawb nqa thoob plaws qhov chaw sib txawv. Piv txwv li, a cell nyuaj yuav teb rau qhov tsaus ntuj ntawm lub teeb tom qab thiab lub teeb ci ntawm qhov tsaus ntuj.
Ntxiv mus, dab tsi yog cov cell yooj yim thiab nyuaj?
Complex cell . Zoo li a yooj yim ntawm tes , ib complex cell yuav teb feem ntau rau cov lus taw qhia thiab txaus siab, txawm li cas los xij nws muaj qib ntawm qhov tsis sib xws. Qhov no txhais tau tias nws qhov chaw txais tsis tuaj yeem raug teeb tsa mus rau qhov chaw ua kom muaj zog thiab muaj kev cuam tshuam.
yam kev txhawb siab twg yuav txhawb nqa cov hlwb yooj yim hauv qhov muag pom? Txawm li cas los xij, peb nkag siab txog tus cwj pwm neuronal hauv tus tsiaj txhu pom kev lawv yog feem ntau yog raws li lawv cov lus teb rau yooj yim dag stimuli xws li qhov chaw ntawm lub teeb thiab sinusoidal gratings.
Raws li, cov cell yooj yim teb rau dab tsi?
Cov Cells Yooj Yim yog V1 neurons uas teb rau stimuli nrog kev taw qhia tshwj xeeb rau cov khoom hauv lawv qhov chaw txais. Zoo li hlwb nyob rau sab nraub qaum geniculate nucleus (LGN), lawv muaj thaj chaw ua kom pom tseeb thiab txwv tsis pub muaj.
Dab tsi yog qhov chaw txais tos?
Cov receptive teb yog ib feem ntawm qhov chaw hnov qab uas tuaj yeem nthuav tawm cov lus teb neuronal thaum txhawb nqa. Txais cov teb tau txheeb xyuas rau cov neurons ntawm lub kaw lus kaw lus, lub cev somatosensory, thiab lub kaw lus pom kev.

Dab tsi yog txheej txheem uas cov cell yooj yim dhau los ua cov cell tshwj xeeb?
Cell sib txawv yog li cas generic embryonic hlwb ua cov hlwb tshwj xeeb. Qhov no tshwm sim los ntawm cov txheej txheem hu ua noob qhia. Kev qhia cov noob yog kev sib xyaw tshwj xeeb ntawm cov noob uas tau qhib lossis tawm (qhia lossis thawb), thiab qhov no yog qhov qhia tias lub xov tooj ntawm tes ua haujlwm li cas
Dab tsi ntawm cov cell hauv qab no yuav raug suav hais tias yog cov kws tshaj lij APCs antigen nthuav tawm cov hlwb?
Cov hom tseem ceeb ntawm APCs yog dendritic cells (DC), macrophages, thiab B cells. Ib tus kws tshaj lij APC coj tus antigen, txheej txheem nws, thiab rov qab ib feem ntawm nws mus rau nws saum npoo, nrog rau chav kawm II loj histocompatibility complex (MHC). Lub T-cell tau qhib thaum nws cuam tshuam nrog cov txheej txheem tsim
Dab tsi yog cov txheej txheem uas tsim ntau cov cell los ntawm ib lub cell?
Lub cell tau txais ib hom kev faib cell hu ua mitosis. Hauv mitosis, ob lub hlwb hu ua tus ntxhais cell raug tsim, txhua qhov zoo ib yam rau niam txiv cell
Dab tsi yog txheej txheem uas lub cell faib ua ob lub cell ntxhais?
Mitosis yog txheej txheem tseem ceeb rau lub neej. Thaum lub sij hawm mitosis, lub xov tooj ntawm tes duplicates tag nrho nws cov ntsiab lus, suav nrog nws cov chromosomes, thiab sib cais los ua ob lub hlwb zoo tib yam. Vim tias cov txheej txheem no tseem ceeb heev, cov theem ntawm mitosis tau ua tib zoo tswj hwm los ntawm cov noob
ICD 10 tus lej yog dab tsi rau keeb kwm ntawm cell cell carcinoma?
Tus kheej keeb kwm ntawm lwm cov qog nqaij hlav malignant ntawm daim tawv nqaij Z85. 828 yog ib daim ntawv them nqi / tshwj xeeb ICD-10-CM code uas tuaj yeem siv los qhia txog kev kuaj mob rau kev them nyiaj rov qab. 2020 tsab ntawm ICD-10-CM Z85. 828 tau pib ua haujlwm thaum Lub Kaum Hli 1, 2019
