A retinal ganglion cell (RGC) yog ib hom neuron nyob ze rau sab hauv (lub ganglion cell txheej) ntawm retina ntawm lub qhov muag. Nws tau txais cov ntaub ntawv pom los ntawm photoreceptors ntawm ob hom neuron nruab nrab: cov hlwb bipolar thiab amacrine cells.
Lub cev ntawm cov hlwb ganglion nyob qhov twg?
Sensory ganglia
Lub cev ntawm somatic sensory thiab visceral sensory neurons muaj nyob rau hauv lub hauv paus dorsal ganglia ntawm tus txha caj qaum, thiab ntawm ganglia ntawm xaiv cranial paj hlwb. Li no hu ua sensory ganglia.
Yuav ua li cas feem ntau cov kab mob qog nqaij hlav retinal txiav tawm qhov twg?
Ganglion cell axons xaus hauv lub lateral geniculate nucleus ntawm thalamus, superior colliculus, lub pretectum, thiab hypothalamus. Kom pom tseeb, tsuas yog hla axons ntawm lub qhov muag sab xis xwb.
Puas muaj pes tsawg lub hlwb retinal ganglion muaj?
Tseem muaj tshaj ib lab retinal ganglion hlwb hauv tib neeg retina, thiab lawv tso cai rau koj pom thaum lawv xa cov duab rau koj lub hlwb.
Yuav ua li cas yog tias tsis muaj cov kab mob qog nqaij hlav retinal?
Retinal ganglion cell (RGC) poob yog qhov pom ntawm optic neuropathies, suav nrog glaucoma, qhov kev puas tsuaj rau RGC axons tshwm sim ntawm theem ntawm lub paj hlwb. Hauv kev sim glaucoma, kev puas tsuaj raug soj ntsuam ntawm qib axon (nyob rau hauv cov paj hlwb retinal fiber ntau txheej thiab lub paj hlwb optic taub hau) lossis ntawm qib soma (hauv retina).
