Retinal ganglion cells txheej txheem cov ntaub ntawv pom uas pib thaum lub teeb nkag mus rau hauv lub qhov muag thiab xa mus rau lub hlwb ntawm lawv cov axons, uas yog cov fibers ntev uas ua rau lub paj hlwb. Muaj ntau tshaj li ib lab lub hlwb hlwb hauv tib neeg retina, thiab lawv tso cai rau koj pom thaum lawv xa cov duab rau koj lub hlwb.
Dab tsi yog ganglion hlwb kuaj tau?
Ganglion hlwb yog qhov kawg tso tawm neurons ntawm vertebrate retina. Ganglion cells sau cov ntaub ntawv hais txog ntiaj teb pom los ntawm cov hlwb bipolar thiab amacrine cells (retinal interneurons). Cov ntaub ntawv no yog nyob rau hauv daim ntawv ntawm tshuaj lom neeg cov lus pom los ntawm receptors ntawm lub ganglion cell membrane.
Dab tsi yog ganglion hlwb hauv kev puas siab puas ntsws?
Ganglion Cells yog neurons uas xa cov ntaub ntawv los ntawm retina mus rau lub hlwb ntawm lub paj hlwb. Muaj tsawg kawg peb chav kawm ntawm ganglion hlwb (midget, parasol, thiab bistratified), uas sib txawv hauv kev ua haujlwm thiab txuas mus rau cov chaw pom kev sib txawv hauv lub hlwb.
ganglion thiab bipolar hlwb ua dab tsi?
Raws li ib feem ntawm retina, cov hlwb bipolar muaj nyob nruab nrab ntawm photoreceptors (rod cells thiab cone cells) thiab ganglion cells. Lawv ua, ncaj qha lossis tsis ncaj, txhawm rau xa cov cim los ntawm photoreceptors mus rau lub hlwb ganglion.
Dab tsi yog ganglion hlwb tso tawm?
Retinal ganglion cell (RGC) pom nyob rau hauv lub ganglion cell txheej ntawm retina. Cov cell uas nyob hauv cov qog adrenalmedulla, qhov chaw uas lawv koom nrog hauv lub paj hlwb tso tawm epinephrine thiab norepinephrine rau hauv cov ntshav.
