Qhov Tseem Ceeb Qhov txawv - Glial Cells vs Neurons
Lub paj hlwb ntawm lub cev yog ntawm ob yam: hauv nruab nrab paj hlwb (CNS) thiab peripheral paj hlwb (PNS). CNS yog tsim los ntawm lub hlwb thiab tus txha caj qaum. Lub cev muaj zog neurons, autonomic paj hlwb, thiab enteric paj hlwb muaj nyob rau hauv PNS. Lub paj hlwb cuam tshuam nrog kev sib kis ntawm cov teeb liab, ob qho tib si hluav taws xob thiab tshuaj lom neeg, txhawm rau tswj hwm qhov sib txawv ntawm kev yeem thiab tsis ua haujlwm ntawm lub cev. Lub paj hlwb yog tsim los ntawm ob hom cell sib txawv: neurons thiab glial hlwb. Neurons yog cov qauv txheej txheem ntawm lub paj hlwb. Neurons koom nrog hauv kev sib kis ntawm hluav taws xob thiab tshuaj teeb liab raws li lub cev los tswj kev yeem thiab tsis ua haujlwm thaum lub sijhawm glial hlwb ua lub luag haujlwm hauv kev tswj hwm homeostasis ntawm lub paj hlwb uas muab kev tiv thaiv txaus thiab kev txhawb nqa hauv kev ua haujlwm ntawm lub paj hlwb. Qhov no yog qhov sib txawv tseem ceeb ntawm glial hlwb thiab neurons.
Glial Cells yog dab tsi?
Glial hlwb, tseem hu ua neuroglia, yog ib hom kev txhawb nqa hlwb hauv nruab nrab paj hlwb. Lawv yog cov hlwb uas tsis yog neural koom nrog hauv kev tswj hwm homeostasis hauv CNS thiab PNS thiab muab kev txhawb nqa thiab kev tiv thaiv rau kev ua haujlwm ntawm lub paj hlwb.
Glial hlwb muaj ob hom: microglia thiab macroglia. Microglia suav hais tias yog macrophages tshwj xeeb uas muaj peev xwm ua phagocytosis thiab rhuav tshem cov kab mob. Macroglia pab nyob rau hauv cov synthesis ntawm myelin thiab muab kev noj haus txaus rau lub paj hlwb. Microglia hlwb muaj xws li oligodendrocytes, astrocytes, ependymal hlwb, Schwann hlwb thiab satellite hlwb. Glial hlwb yog hom cell uas muaj ntau tshaj plaws nyob rau hauv CNS. Astrocytes yog ntau hom glial cell hauv lub hlwb.
Daim duab 01: Hom Glial Cells
Glial hlwb muaj cov haujlwm sib txawv hauv CNS thiab PNS. Lawv nyob ib puag ncig neurons thiab tuav cov neurons nyob rau hauv qhov chaw thiab muab cov as-ham txaus thiab oxygen rau lawv. Neuroglia kuj insulates cov neurons los ntawm kev tsim cov txheej txheem insulating nyob ib ncig ntawm lub axons, rhuav tshem cov kab mob thiab tshem tawm cov neurons tuag ntawm lub paj hlwb.
Neurons yog dab tsi?
Ib neuron yog lub tsev tsim qauv ntawm lub paj hlwb. Nws muaj peev xwm ua tau ob qho tib si hluav taws xob thiab tshuaj lom neeg impulses thoob plaws hauv lub cev txhawm rau tswj kev yeem thiab tsis yeem ua. Kev sib pauv ntawm cov teeb liab ntawm cov neurons tau ua tiav los ntawm qhov muaj cov qauv tshwj xeeb hu ua synapses, txuas nrog ib leeg los tsim ib lub network ntawm neurons. Ib tug raug neuron muaj ib lub cell lub cev hu ua 'soma,' dendrites thiab ib tug axon uas yuav ua tau myelinated nrog Schwann hlwb los yog unmyelinated. Cov neuron yog cov qauv tseem ceeb ntawm CNS thiab autonomic paj hlwb ntawm PNS.
Daim duab 02: Cov qauv ntawm Ib Hom Neuron
Neurons muaj ntau hom raws li lawv ua. Sensory neurons ua cov paj hlwb impulses los ntawm cov stimuli tau txais ntawm lub cev thiab xa mus rau lub hlwb. Lub cev muaj zog neurons ua cov cim ntawm lub hlwb mus rau cov leeg nqaij, lub cev lossis lub caj pas. Intermediate neurons txuas lwm cov neurons ua ke hauv lub hlwb thiab tus txha caj qaum.
Dab tsi zoo sib xws ntawm Glial Cells thiab Neurons?
- Ob leeg neurons thiab glial hlwb yog ib feem ntawm lub paj hlwb.
- Glial cells thiab neurons muaj peev xwm so.

Summary – Glial Cells vs Neurons
Lub paj hlwb yog tsim los ntawm ob yam: CNS thiab PNS. Neurons yog cov qauv txheej txheem ntawm lub paj hlwb thiab koom nrog kev sib kis ntawm cov paj hlwb thoob plaws hauv lub cev. Glial hlwb ua lub luag haujlwm txhawb kev ua haujlwm ntawm lub paj hlwb los ntawm kev tswj hwm homeostasis. Neurons ntawm peb hom: lub cev muaj zog neurons, cov neurons sensory, thiab nruab nrab neurons. Glial hlwb muaj ntau hom; oligodendrocytes, astrocytes, ependymal hlwb, Schwann hlwb, microglia, thiab satellite hlwb. Glial hlwb tsis xa cov paj hlwb, tab sis cov neurons xa ob qho tib si tshuaj lom neeg thiab hluav taws xob teeb liab thoob plaws hauv lub cev. Qhov no yog qhov txawv ntawm glial hlwb thiab neurons.
