Nyob ib ncig ntawm lub cev ntawm tes yog cov paj hlwb hu ua axons thiab dendrites. Dendrites yog ntev, nyias kab laug sab-saib qhovIb lub paj hlwb yuav muaj ntau dua 10,000 dendrites. Lo lus dendrite los ntawm Greek lo lus txhais tau tias "ntoo." Nyob ib ncig ntawm lub cev ntawm tes kuj tseem ntev dua, me ntsis thicker qhov hu ua axon.

Puas yog dendrites paj hlwb Fibres?

neurons. …ntau ntawm cov fibers, hu ua dendrites, rau lub cev ntawm tes; Hauv cov hlab ntsha siab dua, tsuas yog ib qho fiber ntau, lub axon, nqa lub impulse tawm ntawm lub cev ntawm tes. Cov pob khoom ntawm cov fibers los ntawm cov neurons tau tuav ua ke los ntawm cov ntaub so ntswg thiab cov hlab ntsha.

Peb hom paj hlwb yog dab tsi?

Nerve fibers tau muab faib ua peb hom - pawg A paj hlwb, pawg B paj hlwb, thiab pawg C paj hlwb. Cov pab pawg A thiab B yog myelinated, thiab pawg C yog unmyelinated. Cov pab pawg no suav nrog ob qho tib si sensory fibers thiab motor fibers.

Puas yog dendrite ib leeg?

Dendrites (los ntawm Greek δένδρον déndron, "ntoo"), kuj yog dendrons, yog branched protoplasmic extensions ntawm paj hlwb uas propagate lub electrochemical stimulation tau txais los ntawm lwm cov neural hlwb mus rau lub paj hlwb. lub cev ntawm tes, los yog soma, ntawm cov neuron los ntawm qhov project dendrites.

Npaj Fibres yog dab tsi?

Axon, tseem hu ua paj hlwb, feem ntawm lub paj hlwb (neuron) uas nqa cov hlab ntsha tawm ntawm lub cev ntawm tesIb qho neuron feem ntau muaj ib qho axon uas txuas nrog lwm tus. neurons los yog nrog cov leeg nqaij lossis qog hlwb. Qee cov axons yuav ntev heev, ncav cuag, piv txwv li, los ntawm tus txha caj qaum mus rau tus ntiv taw.
