Neurons (paj hlwb) muaj peb ntu uas ua haujlwm ntawm kev sib txuas lus thiab kev koom ua ke: dendrites , cov axons , thiab axon cov dav hlau Lawv muaj ib feem plaub ntawm cev cell los yog tso , uas nqa tawm cov txheej txheem lub neej yooj yim ntawm neurons.
Tom qab ntawd, ib tus tseem tuaj yeem nug, dab tsi yog qhov ntawm cov neuron?
Taw qhia: Lub hlwb tau tsim los ntawm kwv yees li 86 txhiab lub paj hlwb (tseem hu ua "neurons"). Neuron muaj 4 ntu tseem ceeb: dendrites , cov cev cell (tseem hu ua " tso "), cov axon thiab cov axon davhlau ya nyob twg . Dendrites - Kev txuas ntxiv los ntawm neuron cev cell uas coj cov ntaub ntawv mus rau cev cell.
Ntxiv mus, qhov twg ntawm cov hauv qab no tsis yog ib feem ntawm neuron? Txhua lub neuron suav nrog a cev cell (tseem hu ua a tso ), dendrites thiab ib axon . Axons thiab dendrites yog cov hlab ntsha. Synapse yog, tsis raug, tus qauv uas tso cai rau lub neuron kom dhau qhov hluav taws xob lossis cov pa hluav taws xob mus rau lwm lub paj hlwb, yog li, nws tsis yog ib feem ntawm lub paj hlwb.
Kuj paub, 6 feem ntawm neuron yog dab tsi?
Cov qauv ntawm a hlwb : Cov duab saum toj no qhia txog cov txheej txheem yooj yim Cheebtsam ntawm qhov nruab nrab hlwb , suav nrog dendrite, lub cev ntawm tes, nucleus, Node of Ranvier, myelin sheath, Schwann cell, thiab axon davhlau ya nyob twg.
3 hom neurons yog dab tsi?
Txog rau tus txha nqaj qaum txawm li cas los xij, peb tuaj yeem hais tias muaj peb hom neurons: kev nkag siab, lub cev muaj zog, thiab kev ua haujlwm sab hauv
- Lub paj hlwb.
- Tsav tsheb neurons.
- Interneurons.
- Neurons hauv lub hlwb.

Yam twg ntawm cov hauv qab no feem ntau yog kab mob ntawm cov tsiaj muaj tsiaj?
Anthrax Ib yam li ntawd, koj tuaj yeem nug, yam twg ntawm cov hauv qab no tau txheeb pom tias yog tus pab txhawb rau mob plawv? Ntshav siab, haus luam yeeb, thiab ntshav siab tseem yog qhov tseem ceeb tus pab mus rau lub teb chaws kev kis mob ntawm kab mob plawv .
Yam twg ntawm cov hauv qab no yog daim ntawv feem ntau ntawm cov leeg nqaij hauv cov neeg laus?
Myotonic (tseem hu ua MMD lossis Steinert's disease). Feem ntau ntawm cov leeg nqaij dystrophy hauv cov neeg laus, myotonic musculoskeletal dystrophy cuam tshuam rau txiv neej thiab poj niam, thiab nws feem ntau tshwm sim txhua lub sijhawm txij thaum menyuam yaus txog rau neeg laus
Qhov twg ntawm cov hauv qab no suav tias yog cov qog ua haujlwm ntxiv hauv cov zom zaub mov?

Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Qhov twg ntawm cov hauv qab no yog qhov sib txawv loj ntawm cov pas nrig thiab lub khob hliav qab?
Cov pas nrig yog lub luag haujlwm rau qhov pom ntawm qhov tsis pom kev qis (scotopic vision). Lawv tsis kho qhov muag pom xim, thiab muaj qhov tsis tshua pom kev zoo. Cones yog nquag nyob rau theem siab dua (photopic vision), muaj peev xwm ntawm kev pom xim thiab muaj lub luag haujlwm rau siab spatial acuity
