Afferent neurons yog cov paj hlwb Lub cev tseem ceeb ntawm cov neurons afferent nyob ze ntawm lub hlwb thiab tus txha caj qaum, uas suav nrog lub hauv paus paj hlwb. Lub cev ntawm tes tseem ceeb ntawm afferent neurons nyob ze ntawm lub hlwb thiab tus txha caj qaum, uas suav nrog lub hauv nruab nrab lub paj hlwb.
Qhov twg afferent thiab efferent neurons nyob?
Lub ventral cag ntawm tus txha caj qaumnyob rau sab xub ntiag, thaum lub hauv paus dorsal nyob tom qab. Afferent neurons nkag mus rau tus txha caj qaum los ntawm dorsal cag, nqa cov cim ntawm lub cev mus rau lub hlwb. Efferent neurons tawm ntawm tus txha caj qaum los ntawm lub hauv paus ventral ua ntej cuam tshuam nrog lawv cov leeg lub hom phiaj.
Qhov twg afferent neurons efferent neurons thiab interneurons nyob hauv lub paj hlwb?
Ib hom thib peb ntawm neuron, hu ua interneuron lossis koom haum neuron, ua raws li tus neeg nruab nrab ntawm cov afferent thiab efferent neurons. Cov neurons no nyob hauv lub hauv nruab nrab lub paj hlwb (lub hlwb thiab qaum qaum).
Ib qho piv txwv ntawm ib qho afferent neuron yog dab tsi?
Neurons uas tau txais cov ntaub ntawv los ntawm peb lub cev hnov qab (piv txwv li qhov muag, tawv nqaij) thiab xa cov tswv yim no mus raulub paj hlwb hauv nruab nrab hu ua afferent neurons.
Yuav ua li cas yog efferent thiab afferent?
Tus afferent lossis kev sib faib kev hnov lus xa cov impulses los ntawm cov kab mob peripheral mus rau CNS. Lub efferent los yog lub cev muaj zog faib kisimpulses los ntawm CNS tawm mus rau cov kab mob peripheral ua rau muaj kev cuam tshuam lossis kev ua.

Kev tsis ncaj ncees nyob qhov twg yog qhov hem rau kev ncaj ncees nyob txhua qhov chaw?
Martin Luther King tau hais tias: “Kev tsis ncaj ncees nyob txhua qhov chaw yog kev hem thawj rau kev ncaj ncees nyob txhua qhov chaw. Peb raug ntes nyob rau hauv ib tug inescapable network ntawm kev sib nrig sib pab, khi nyob rau hauv ib lub tsoos tsho ntawm txoj hmoo.
Qhov twg yog qhov tsis txaus ntseeg nyob qhov twg?
Yuav muaj ob lub cev tsis zoo nyob rau hauv lub midbrain. Lawv yog symmetrically positioned, ib tug nyob rau ntawm ob sab ntawm lub midline ntawm lub hlwb, thiab lawv tsim ob lub pob nyob rau hauv lub posterior nto ntawm lub paj hlwb nyob rau hauv qab ntawm lub superior colliculi.
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.
Dendrites nyob qhov twg ntawm cov neuron?
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.
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.
