Structure of a neuron. Ntawm ib kawg ntawm lub cev ntawm tes (thiab qhov tseeb, nyob ib ncig ntawm feem ntau ntawm nws cov periphery) muaj ntau yam me me, branching protrusions hu ua dendrites. Extending los ntawm lwm qhov kawg ntawm lub cev ntawm tes ntawm qhov chaw hu ua axon hillock yog lub axon, ntev, nyias, raj zoo li protrusion.
lub dendrite nyob qhov twg?
Dendrites (dendron=ntoo) yog cov ntoo zoo li cov ntoo membranous arising los ntawm lub cev ntawm cov neuron, txog 5–7 ib neuron nyob nruab nrab, thiab txog 2 μm nyob rau hauv ntev.. Lawv feem ntau yog ceg, tsim kom muaj qhov ntom ntom zoo li arborization hu ua tsob ntoo dendritic nyob ib ncig ntawm cov neuron.
cov dendrites nyob qhov twg thiab lawv ua dab tsi?
Dendrites yog tsob ntoo zoo li txuas ntxiv thaum pib ntawm cov neuron uas pab nce thaj tsam ntawm lub cev ntawm tes. Cov me me protrusions tau txais cov ntaub ntawv los ntawm lwm cov neurons thiab xa hluav taws xob stimulation mus rau soma. Dendrites kuj tau them nrog synapses.
Perikaryon ntawm neuron nyob qhov twg?
Txhua neuron yog tsim los ntawm lub cev ntawm tes (perikaryon) thiab cov txheej txheem ntawm tes. Lawv nyob hauv qhov teeb meem grey ntawm lub hauv paus paj hlwb, qhov muag (rods thiab cones), pob ntseg (organ ntawm Corti), olfactory mucosa, thiab ganglia. Nws suav nrog cov nucleus thiab nws nyob ib puag ncig cytoplasm.
Dendrites nyob qhov twg ntawm lub paj hlwb?
Cov dendrites ntawm ib lub paj hlwb pom tau sab nraumtus txha caj qaum nyob rau hauv daim tawv nqaij, cov leeg nqaij los yog caj pas ntawm lawv cov receptors tshwj xeeb. Lawv axons xaus rau hauv tus txha caj qaum uas lawv txuas nrog cov dendrites ntawm lwm cov neurons.

Leej twg nyob rau ntawm daim npog ntawm cov neeg nyob hauv lub zos phem?
Tab sis Ethan Winters, White systems engineer lub hnub qub ntawm "Resident Evil 8: Village," yog tib lub cim tseem ceeb hauv koob uas nws lub cev peb nyob. Vim peb saib los ntawm nws ob lub qhov muag, thiab qhov kev ua si insistence ntawm obscuring nws lub ntsej muag, peb ntxiv txheeb xyuas nrog nws.
Qhov twg tag nrho cov nqi hluav taws xob nyob ntawm qhov kev siv nyiaj siab tshaj plaws yog qhov twg?
marginal utility is zero. Tag nrho cov nqi hluav taws xob yog siab tshaj thaum marginal utility yog xoom. Qhov no yog vim muaj ntau txoj cai ntawm kev txo qis marginal utility uas hais tias tus neeg siv khoom noj ntau thiab ntau qhov zoo, qhov ntxiv rau tag nrho cov nqi hluav taws xob poob.
Nyob rau hauv ib lub neuron qhov twg voltage-gated calcium channel nyob?
Voltage-gated calcium channels (VGCCs), tseem hu ua voltage-dependent calcium channels (VDCCs), yog ib pab pawg ntawm voltage-gated ion channels pom nyob rau hauv daim nyias nyias ntawm cov hlwb excitable (xws li, cov leeg, glial hlwb, neurons, thiab lwm yam.
Ntawm cov neurons yog cov dendrites nyob?
Structure of a neuron. Ntawm ib kawg ntawm lub cev ntawm tes (thiab qhov tseeb, nyob ib ncig ntawm feem ntau ntawm nws cov periphery) muaj ntau yam me me, cov ceg ntoo hu ua dendrites. Txuas ntxiv los ntawm lwm qhov kawg ntawm lub cev ntawm tes ntawm qhov chaw hu ua axon hillock axon hillock Lub axon hillock yog ib feem tshwj xeeb ntawm lub cev ntawm tes (lossis soma) ntawm cov neuron uas txuas rau axon.
Qhov twg yog qhov kev sib raug zoo ntawm stereochemical ntawm ob khub ntawm cov molecules?
Enantiomers thiab diastereomers tsuas yog ob qho kev sib raug zoo stereochemical uas koj tuaj yeem muaj ntawm ob lub molecules. Cov stereoisomers yog ob lub molecules uas ua tiav ob qhov kev xav tau hauv qab no: Ob lub molecules yuav tsum muaj tib lub qauv molecular, thiab.
