Qhov sib txawv tseem ceeb ntawm afferent thiab efferent neuron yog tias afferent neurons nqa cov paj hlwb los ntawm cov kab mob hauv lub cev mus rau lub paj hlwb hauv nruab nrab thaum cov paj hlwb muaj zog nqa cov hlab ntsha los ntawm lub hauv nruab nrab paj hlwb mus rau cov leeg.
Lub paj hlwb yog tus thawj coj ntawm txhua lub cev ua haujlwm. Nws lub luag haujlwm tseem ceeb suav nrog kev sib txuas lus ntawm lub cev thiab tswj lub cev. Tsis tas li ntawd, lub paj hlwb muaj ob lub hlwb loj xws li neuron thiab neuroglia. Lub neuron yog cov qauv thiab kev ua haujlwm ntawm lub paj hlwb. Lawv yog cov hlwb tshwj xeeb uas teb rau cov tshuaj lom neeg thiab lub cev stimuli thiab ua cov lus thoob plaws hauv lub cev. Feem ntau, tib neeg lub hlwb tuaj yeem tswj hwm ntau dua 10 billion neurons txhua lub sijhawm. Txhua neuron muaj peb ntu; uas yog, lub cev ntawm tes, ib qho axon, thiab ntau dendrites. Axon thiab dendrites yog cov txheej txheem ntawm cov neuron. Tsis tas li ntawd, nyob ntawm cov duab thiab kev ua haujlwm ntawm cov neurons, muaj peb hom neurons; uas yog, afferent neurons, interneurons, thiab efferent neurons. Peb hom no muaj cov yam ntxwv sib txawv thiab kev ua haujlwm. Ntawm no, cov neurons afferent yog cov neurons hnov mob thaum cov neurons efferent yog lub cev muaj zog neurons.
Dab tsi yog Afferent?
Afferent neurons yog cov neurons uas nqa cov ntaub ntawv hnov zoo li paj hlwb impulse los ntawm lub cev puas siab puas ntsws mus rau hauv nruab nrab lub paj hlwb. Cov kab mob hauv lub cev tau txais stimuli los ntawm ib puag ncig thiab xa cov teeb liab mus rau hauv nruab nrab lub paj hlwb ntawm kev hnov qab neurons. Cov neurons no yog cov hlwb tshwj xeeb, thiab los ntawm ntau qhov chaw ntawm lub cev, lawv nqa cov cim rau lub hlwb thiab qaum qaum. Txhawm rau piav qhia ntxiv, cov qauv ntawm lub cev xws li lub teeb, suab, qhov kub thiab txias, thiab lwm yam. qhib lub afferent neurons. Lub sensory receptors nyob rau ntawm lub cell membrane muaj peev xwm hloov cov stimuli mus rau hauv hluav taws xob paj hlwb impulses.
Daim duab 01: Afferent Neuron
Dhau li ntawm, afferent neurons yog pseudounipolar neurons uas muaj ib qho ntev ntev dendrite thiab luv axon. Lawv lub cev ntawm tes yog du, puag ncig zoo li tus thiab nyob rau hauv lub paj hlwb peripheral. Tsis tas li ntawd, lawv cov axons taug kev los ntawm ganglion mus rau ganglion thiab coj rov qab mus rau qaum qaum. Ib leeg ntev myelinated dendrite zoo ib yam li axon thiab yog lub luag haujlwm rau kev xa cov ntaub ntawv hnov lus lossis paj hlwb los ntawm kev hnov lus receptors rau nws lub cev ntawm tes.
Yuav Ua Li Cas Yog Dab Tsi?
Efferent neurons (tseem hu ua lub cev muaj zog neurons) tuaj yeem pom hauv nruab nrab lub paj hlwb (hauv qhov teeb meem grey ntawm qaum qaum thiab medulla oblongata), thiab lawv yog lub luag haujlwm tau txais cov ntaub ntawv los ntawm lub hauv paus paj hlwb thiab xa cov paj hlwb. impulse rau periphery ntawm lub cev xws li cov leeg, qog thiab lwm yam.
Daim duab 02: Efferent Neuron
Lub cev ntawm lub cev ntawm lub cev muaj zog neuron muaj cov duab satellite. Tsis tas li ntawd, nws muaj ib tug ntev axon thiab ob peb luv dendrites. Tsis tas li ntawd, axon tsim ib qho kev sib txuas neuromuscular nrog cov nyhuv. Li no, lub impulse nkag mus los ntawm dendrites thiab tso nws los ntawm ib qho axon mus rau lwm qhov kawg.
Dab tsi yog qhov zoo sib xws ntawm Afferent thiab Efferent?
- Afferent thiab Efferent yog cov paj hlwb ntawm lub paj hlwb
- Lawv muaj lub cev ntawm tes, dendrites thiab axon.
- Kuj, ob qho tib si txuas nrog lub hauv nruab nrab paj hlwb.
- Lawv xa paj hlwb impulses.
Qhov txawv ntawm Afferent thiab Efferent yog dab tsi?
Afferent neurons nqa cov hlab ntsha impulses mus rau hauv nruab nrab lub paj hlwb los ntawm lub cev. Nyob rau hauv sib piv, efferent neurons nqa paj hlwb impulses los ntawm lub hauv paus paj hlwb mus rau cov leeg. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm afferent thiab efferent neurons. Tsis tas li ntawd, afferent neurons yog cov neurons sensory nrog luv axon thaum efferent neurons yog lub cev muaj zog neurons nrog ntev axon. Li no, ib qho sib txawv ntawm afferent thiab efferent neurons yog qhov ntev ntawm axon. Ntawd yog, cov neurons afferent muaj luv axons piv rau efferent neurons, uas muaj ntev axons.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm afferent thiab efferent neurons nrog cov ntsiab lus ntxiv.
Summary – Afferent vs Efferent
Afferent thiab efferent neurons yog ob hom neurons loj nyob hauv lub paj hlwb. Afferent neurons coj cov paj hlwb impulses tsim los ntawm cov khoom nruab nrog cev mus rau hauv nruab nrab paj hlwb. Receptors ntawm lub cev hnov tsw tau txais sab nraud stimuli thiab tsim rau hauv cov hlab ntsha impulses thiab xa mus rau lub hlwb thiab tus txha caj qaum los ntawm afferent neurons, uas yog cov neurons sensory. Yog li ntawd, lawv xa cov teeb liab hauv ib qho kev taw qhia. Ntawm qhov tod tes, efferent neurons pib los ntawm lub hauv nruab nrab lub paj hlwb thiab nqa cov hlab ntsha impulses los ntawm lub hauv paus paj hlwb mus rau cov leeg thiab cov qog. Lawv yog lub cev muaj zog neurons. Qhov no yog qhov txawv ntawm afferent thiab efferent neuron.
