Zoo li lwm lub hlwb, soma muaj cytoplasm, mitochondria, nucleus, ntxhib endoplasmic reticulum, thiab Golgi complex. Floating nyob rau hauv lub cytoplasm ntawm lub cell lub cev yog irregularly zoo li tus hais tias Nissl cev ”, cov kws tshawb fawb xav tias lawv yog lub luag haujlwm rau sib sau ua cov protein.

Tom qab ntawd, nissl lub cev yog dab tsi?

Lub cev Nissl, tseem hu ua Nissl tshuaj thiab Nissl cov khoom, yog lub cev loj loj pom hauv cov neurons. Cov granules no yog ntxhib endoplasmic reticulum (RER) nrog rosettes dawb cov ribosomes , thiab yog qhov chaw ntawm cov protein synthesis.

Tseem Paub, vim li cas nissl lub cev tsis nyob hauv axon? Hauv lub cell lub cev lawv hla ib leeg los tsim lub network sib sib zog nqus, tab sis tsis muaj ib tus ntawm lawv tiag tiag ceg. Cov Nissl cev feem ntau loj nyob rau hauv lub cev muaj zog tshaj nyob rau hauv sensory hlwb thiab yog tsis nyob nyob rau hauv cheeb tsam ntawm lub cell lub cev hu ua ' axon hillock', uas ua rau nce mus rau axon.

Raws li txoj cai, nissl lub cev puas ua cov tshuaj neurotransmitters?

Nrog cov tshuab hluav taws xob me me lawv tau pom kom muaj cov granular (ntxhib) endoplasmic reticulum, pab pawg ntawm cisternae nrog txuas thiab pub dawb ribosomes uas muaj RNA thiab txhawj xeeb hauv kev tsim cov protein tsim nyog rau cov metabolism hauv xovtooj thiab kev saib xyuas cov qauv. Qee cov neurons synthesize peptide cov neurotransmitters los yog cov tshuaj hormones

Peb tuaj yeem nrhiav nissl's granules nyob qhov twg?

Nissl cov granules muaj nyob hauv cytoplasm ntawm lub cev cell ntawm cov neurons nrog rau lwm cov cell organelles zoo li Golgi apparatus, endoplasmic reticulum, mitochondria, nucleus, thiab lwm yam. granules muab cov tsos xim me ntsis rau cytoplasm ntawm lub cev ntawm tes. Lawv pab nyob rau hauv protein synthesis nyob rau hauv lub neurons.
