Lub paj hlwb peripheral (PNS), uas muaj cov neurons thiab qhov chaw ntawm cov neurons pom sab nraum CNS, suav nrog cov paj hlwb thiab lub cev muaj zog neurons.
Puas muaj cov neurons hauv PNS?
Nerves ntawm lub paj hlwb peripheral raug cais raws li hom neurons lawv muaj - hnov, lub cev muaj zog lossis cov hlab ntsha sib xyaw(yog tias lawv muaj ob qho tib si hnov qab thiab lub cev muaj zog neurons), xws li nrog rau cov kev taw qhia ntawm cov ntaub ntawv ntws - mus rau lossis deb ntawm lub hlwb.
Puas yog tag nrho cov neurons hnov qab hauv PNS afferent?
Structure of a Nerve
Ib paj hlwb muaj bundles ntawm paj fibers, xws li axons los yog dendrites, surrounded los ntawm cov ntaub so ntswg. Sensory qab haus huv tsuas muaj afferent fibers, ntev dendrites ntawm sensory neurons. Lub cev muaj zog paj hlwb tsuas muaj efferent fibers, ntev axons ntawm lub cev muaj zog neurons. Cov paj hlwb sib xyaw muaj ob hom fibers.
PNS puas muaj qhov hnov qab?
PNS yog lub network loj ntawm tus txha caj qaum thiab lub paj hlwb uas txuas rau lub hlwb thiab qaum qaum. Nws muaj sensory receptors uas pab ua kev hloov pauv hauv ib puag ncig sab hauv thiab sab nraud. Cov ntaub ntawv no raug xa mus rau CNS ntawm afferent sensory nerves.
Cov neurons nyob qhov twg?
Lub cev ntawm tes ntawm cov neurons hnov qab nyob hauv lub dorsal ganglia ntawm qaum qaum. Cov ntaub ntawv xav tau taug kev raws cov paj hlwb afferent hauv lub paj hlwb, mus rau lub hlwb ntawm tus txha caj qaum.
