Lawv qee zaum hu ua fibers. Dendrites feem ntau, tab sis tsis yog ib txwm, luv luv thiab branching, uas ua rau lawv cov cheeb tsam saum npoo kom tau txais cov cim los ntawm lwm cov neurons. Tus naj npawb ntawm dendrites ntawm cov neuron sib txawv. Lawv hu ua afferent processes vim tias lawv xa cov impulses mus rau neuron cell neuron cell Ib hom cell uas tau txais thiab xa cov lus ntawm lub cev mus rau lub hlwb thiab rov qab mus rau lub cev. Cov lus xa los ntawm cov hluav taws xob tsis muaj zog. Kuj hu ua neuron. https://www.cancer.gov › mob cancer-terms › def › paj hlwb

Puas afferent neurons muaj dendrites?
Afferent neurons yog pseudounipolar neurons uas muaj ib qho axon tawm hauv lub cev ntawm tes faib ua ob ceg: qhov ntev mus rau lub cev, thiab qhov luv mus rau hauv nruab nrab lub paj hlwb (xws li qaum qaum). Cov cells tsis muaj dendrites uas feem ntau muaj nyob hauv cov neurons
Cov neurons twg txuas afferent thiab efferent neurons?
Ib yam thib peb ntawm neuron, hu ua tus interneuron lossis koom haum neuron, ua ib hom neeg nruab nrab ntawm cov afferent thiab efferent neurons. Cov neurons no nyob rau hauv nruab nrab lub paj hlwb (lub hlwb thiab tus txha caj qaum).
Dendrites yog dab tsi?
Dendrites yog appendages uas tau tsim kom tau txais kev sib txuas lus los ntawm lwm lub hlwbLawv zoo ib yam li tsob ntoo zoo li cov qauv, tsim cov phiaj xwm uas ua rau muaj zog los ntawm lwm cov neurons thiab ua tus nqi hluav taws xob rau lub lub cev ntawm tes (los yog, tsis tshua muaj, ncaj qha mus rau axons).
Dab tsi yog qhov ua haujlwm ntawm dendrites hauv neuron?
Feem ntau cov neurons muaj ntau yam dendrites, uas nthuav tawm sab nraud ntawm lub cev ntawm tes thiab tshwj xeeb kom tau txais cov cim qhia tshuaj los ntawm axon termini ntawm lwm cov neurons. Dendrites hloov cov teeb liab no rau hauv cov hluav taws xob me me thiab xa mus rau sab hauv, nyob rau hauv kev coj ntawm lub cev ntawm tes
