Qhov sib txawv tseem ceeb ntawm kev sib txawv ntawm cov kab mob bipolar thiab unipolar neurons yog cov neurons multipolar muaj ntau dendrites thiab ib qho axon, thaum cov neurons bipolar muaj ib qho axon thiab ib lub dendrite thiab unipolar neurons tsuas muaj ib txoj kev protoplasmic xwb.
Ib neuron lossis lub paj hlwb yog cov qauv tsim thiab kev ua haujlwm ntawm lub paj hlwb. Nws yog ib qho hluav taws xob ua kom muaj zog ntawm tes. Neurons tau txais cov teeb liab los ntawm lub ntiaj teb sab nraud los ntawm cov khoom siv hauv nruab nrog cev thiab xa mus rau hauv nruab nrab lub paj hlwb kom ua tiav. Tom qab ntawd, cov neurons xa cov cim los ntawm lub hlwb thiab qaum qaum mus rau lwm qhov ntawm lub cev, tshwj xeeb tshaj yog rau cov leeg thiab cov qog hlwb. Ua li no, neurons pab kev sib txuas lus hauv peb lub cev.
Ib tug neuron muaj peb yam tseem ceeb: ib qho axon, dendrites thiab lub cev ntawm tes. Neurons tau txais cov cim los ntawm dendrites. Tom qab ntawd lub teeb liab taug kev ntawm lub cev ntawm tes mus rau axon. Los ntawm axon, lub teeb liab mus rau tom ntej neuron los ntawm lub synapse. Neurons tuaj yeem yog unipolar, pseudounipolar, bipolar lossis multipolar. Feem ntau cov neurons yog multipolar, hos ntau yog bipolar. Txawm li cas los xij, muaj unipolar thiab pseudounipolar neurons, ib yam nkaus.
Dab tsi yog Multipolar Neurons?
Multipolar neurons yog hom neurons ntau tshaj plaws, muaj peb lossis ntau dua cov txheej txheem protoplasmic. Feem ntau, cov neurons no muaj ib qho axon thiab ntau dendrites. Ntau tshaj 99% ntawm tag nrho cov neurons nyob rau hauv tib neeg yog multipolar. Yog li ntawd, lawv yog hom loj ntawm cov neurons pom nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab cov efferent faib ntawm lub paj hlwb peripheral.
Daim duab 01: Multipolar Neurons
Dab tsi yog Bipolar Neurons?
Bipolar neurons yog ib hom neurons uas muaj ob txheej txheem txuas ntxiv ntawm lub cev ntawm tes. Feem ntau, cov txheej txheem ob no khiav ntawm qhov sib txawv ntawm lub cev ntawm lub cev. Ib txheej txheem yog ib qho axon thaum lwm cov txheej txheem yog dendrite.
Daim duab 02: Bipolar Neuron
Hauv kev sib piv rau cov neurons multipolar, bipolar neurons muaj tsawg tus lej. Lawv pom nyob rau hauv lub retina ntawm lub qhov muag thiab lub olfactory system.
Dab tsi yog Unipolar Neurons?
Ib tug unipolar neuron yog ib tug neuron uas tsuas muaj ib tug protoplasmic txheej txheem. Yog li, unipolar neurons tsuas muaj ib qho qauv txuas ntawm lub cev ntawm tes lossis soma.
Daim duab 03: Unipolar Neuron
Feem ntau, unipolar neurons muaj nyob rau hauv cov pob txha tsis muaj zog, tshwj xeeb tshaj yog nyob rau hauv cov kab txhawm rau txhawm rau txhawb cov leeg lossis cov qog. Hauv cov tsiaj nyeg, lawv feem ntau pom nyob rau hauv kev faib tawm ntawm PNS.
Dab tsi yog qhov zoo sib xws ntawm Multipolar Bipolar thiab Unipolar Neurons?
- Multipolar, bipolar thiab unipolar neurons yog peb ntawm plaub hom neurons pom hauv peb lub paj hlwb.
- Lawv raug cais raws li cov txheej txheem uas nthuav tawm ntawm lub cev ntawm tes.
- Ntxiv mus, tsis muaj cov txheej txheem protoplasmic tawm los ntawm soma.
Qhov txawv ntawm Multipolar Bipolar thiab Unipolar Neurons yog dab tsi?
Multipolar neurons muaj peb lossis ntau dua cov txheej txheem protoplasmic, tshwj xeeb tshaj yog ib qho axon thiab ntau dendrites, thaum bipolar neurons muaj ob txheej txheem protoplasmic, tshwj xeeb tshaj yog ib qho axon thiab ib lub dendrite txuas ntawm soma thiab unipolar neurons tsuas muaj ib txheej txheem txuas ntxiv ntawm soma.. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm multipolar bipolar thiab unipolar neurons. Nyob rau hauv tib neeg, ntau tshaj 99% ntawm tag nrho cov neurons yog multipolar neurons, thaum bipolar neurons tsis tshua muaj thiab unipolar neurons tsawg heev.
Ntxiv mus, ntau lub paj hlwb pom muaj nyob hauv CNS thiab kev faib tawm ntawm PNS thaum lub paj hlwb bipolar pom nyob rau hauv retina ntawm lub qhov muag, thiab olfactory system thiab unipolar neurons muaj feem ntau nyob rau hauv afferent division ntawm PNS. thiab nyob rau hauv kab. Yog li, qhov no yog lwm qhov sib txawv ntawm multipolar bipolar thiab unipolar neurons.
Summary – Multipolar Bipolar vs Unipolar Neurons
Raws li tus lej ntawm cov txheej txheem protoplasmic tawm los ntawm soma, muaj plaub hom neurons xws li unipolar, bipolar, multipolar thiab pseudounipolar. Multipolar neurons muaj ib qho axon thiab ntau dendrites txuas ntawm lub cev ntawm tes. Bipolar neurons muaj ib tug axon thiab ib tug dendrite. Unipolar neurons tsuas muaj ib qho txheej txheem protoplasmic txuas los ntawm lub cev ntawm tes. Yog li nws yog qhov sib txawv tseem ceeb ntawm multipolar bipolar thiab unipolar neurons. Multipolar neurons yog qhov ntau tshaj thaum muaj ntau cov neurons bipolar. Txawm li cas los xij, muaj unipolar neurons tam sim no nyob rau hauv lub paj hlwb, tab sis lawv cov naj npawb tsawg heev piv rau lwm ob hom.
