Interneurons yog nyob nkaus hauv CNS . Lawv tsim txog li 99% ntawm tag nrho cov neurons thiab muaj ob lub luag haujlwm tseem ceeb: Lawv yog nyob ntawm afferent thiab efferent neurons , thiab yog li ntawd ua hauj lwm los muab tag nrho cov ntaub ntawv thiab cov lus teb los ntawm cov no neurons ua ke.

Ib yam nkaus, tib neeg nug, cov paj hlwb twg tsuas yog nyob hauv CNS?

Interneurons , uas pom tsuas yog hauv CNS, txuas ib lub neuron mus rau lwm tus. Lawv tau txais cov ntaub ntawv los ntawm lwm lub paj hlwb (xws li lub paj hlwb lossis lossis interneurons ) thiab xa cov ntaub ntawv mus rau lwm cov neurons (ib yam nkaus lub cev muaj zog neurons los yog interneurons ).

Ib yam li ntawd, nyob qhov twg neuron cell lub cev pom hauv CNS hauv PNS? Thaum cov interneurons tag nrho nyob hauv lub CNS , feem ntawm afferent thiab efferent neurons qhov project tawm ntawm lub CNS thiab tsim cov hlab ntsha ntawm lub PNS . Cov cell cev ntawm afferent neurons nyob hauv cov qauv tsis sib xws hu ua ganglia nyob ze cov CNS.

Kuj Paub, pes tsawg tus neurons nyob hauv CNS?

Qhov nruab nrab tib neeg lub hlwb muaj txog 86 billion neurons (los yog paj hlwb ) thiab ntau ntau neuroglia (los yog glial hlwb) uas pab txhawb thiab tiv thaiv cov neurons (txawm hais tias pom qhov kawg ntawm nplooj ntawv no kom paub ntau ntxiv txog cov glial cells).

Cov neurons hnov qab nyob qhov twg?

Cov ntawm tes lub cev ntawm lub paj hlwb hnov nyob hauv qab daus ganglia ntawm tus txha nqaj qaum.
