Ib feem ntawm neuron
Neurons sib txawv ntawm qhov loj me, cov duab, thiab cov qauv nyob ntawm lawv lub luag haujlwm thiab qhov chaw. Txawm li cas los xij, yuav luag tag nrho cov neurons muaj peb qhov tseem ceeb: a cev cell , ib axon , thiab dendrites.
Kuj nug, dab tsi yog cov qauv loj ntawm cov neuron?
Lub hauv paus tseem ceeb ntawm cov neuron yog cov soma ( cev cell ), cov axon (ib qhov ntev slender projection uas ua hluav taws xob impulses deb ntawm lub cev cell ), dendrites (tsob ntoo zoo li cov qauv uas tau txais cov lus los ntawm lwm tus neurons), thiab synapses (tshwj xeeb kev sib tshuam ntawm cov neurons).
Tsis tas li ntawd, lub hauv paus qauv thiab kev ua haujlwm ntawm neuron yog dab tsi? Yog li, los tshuaj xyuas, cov neurons yog cov hlwb tshwj xeeb ntawm lub paj hlwb uas xa cov cim thoob plaws lub cev. Neurons muaj cov ntawv txuas ntxiv uas nthuav tawm los ntawm ntawm tes lub cev hu ua dendrites thiab axons. Dendrites yog txuas ntxiv ntawm cov neurons uas tau txais signals thiab coj lawv mus rau lub ntawm tes lub cev.
Ib yam li ntawd, lub neuron yog dab tsi?
Ib qho raug neuron muaj ib lub cev ntawm tes (soma), dendrites, thiab ib qho axon. Lub soma feem ntau yog compact. Cov axon thiab dendrites yog filaments uas extrude los ntawm nws.
