Key Difference – Nerve vs Vein
Peb lub cev muaj kev sib txuas uas yog lub luag haujlwm thauj khoom ntawm ib qho mus rau lwm qhov. Txawm hais tias cov khoom no muaj lub hom phiaj zoo sib xws hauv cov kab mob lom neeg, lawv cov qauv sib txawv vim lawv cov haujlwm sib txawv. Cov hlab ntsha thiab cov hlab ntsha yog ob feem ntawm cov tes hauj lwm uas thauj cov hlab ntsha thiab cov ntshav raws. Qhov sib txawv tseem ceeb ntawm cov hlab ntsha thiab cov hlab ntsha yog tias lub network ntawm lub paj hlwb yog tsim los ntawm cov hlab ntsha thaum lub circulatory system yog tsim los ntawm cov leeg. Muaj lwm qhov sib txawv ntawm cov hlab ntsha thiab cov leeg ntawm lawv cov qauv, kev ua haujlwm, thiab lwm yam., uas tau tham ntawm no kom ntxaws.
Nerve yog dab tsi?
Ib lub paj hlwb yog tsim los ntawm ntau txhiab lub paj hlwb uas nyob rau hauv ib qho kev sib txuas sab nraud. Cov paj hlwb txuas nrog cov paj hlwb hu ua neurons. Lub paj hlwb yog ib qho ntev axon lossis dendrite ntawm neuron. Nyob ntawm seb muaj lossis tsis muaj myelin sheath, muaj ob hom paj hlwb; uas yog, myelinated paj fibers thiab nonmyelinated paj fibers. Cov paj hlwb hloov hluav taws xob hluav taws xob hluav taws xob thoob plaws hauv lub paj hlwb thiab yog lub luag haujlwm rau kev hnov lus / lus teb hauv lub cev. Tsis yog tag nrho cov hlab ntsha yog interconnected. Cov paj hlwb pib feem ntau los ntawm lub hlwb thiab qaum qaum. Raws li qhov xwm txheej ntawm cov hlab ntsha impulse, cov hlab ntsha tau muab faib ua peb hom; cov paj hlwb, cov paj hlwb, thiab cov paj hlwb sib xyaw.
Sensory qab haus huv yog tsim los ntawm cov paj hlwb nkaus xwb thiab ua cov paj hlwb impulses los ntawm peripheral cov ntaub so ntswg mus rau hauv nruab nrab lub paj hlwb thiaj li tsim tau qhov kev xav. Lub cev muaj zog neurons tsuas muaj lub cev muaj zog thiab muaj lub luag haujlwm rau kev ua cov hlab ntsha ntawm lub hauv nruab nrab paj hlwb mus rau cov leeg lossis cov qog. Cov paj hlwb sib xyaw muaj ob qho tib si kev hnov lus thiab lub cev muaj zog paj hlwb, thiab ua kom pom lub cev thiab lub cev muaj zog.
Nervous System
Vim yog dab tsi?
Cov hlab ntsha yog cov qauv zoo li lub raj uas nqa cov ntshav mus rau lub plawv los ntawm thoob plaws lub cev. Tsis zoo li lub paj hlwb, tib neeg circulatory system yog ib tug kaw network thiab tag nrho cov hlab ntsha yog interconnected. Cov hlab ntsha tseem ceeb hauv tib neeg lub cev muaj xws li cov hlab ntsha jugular, lub raum cov hlab ntsha, cov hlab ntsha subclavian, cov hlab ntshav siab portal, thiab femoral leeg. Feem ntau cov hlab ntsha nqa cov ntshav deoxygenated tshwj tsis yog cov hlab ntsws pulmonary thiab umbilical vein.
Cov phab ntsa ntawm cov leeg tsis tshua muaj cov leeg thiab feem ntau pom ze rau ntawm daim tawv nqaij. Feem ntau, sab nrauv phab ntsa ntawm cov leeg yog tsim los ntawm cov ntaub so ntswg, hu ua tunica adventitia. Cov txheej hauv nruab nrab yog hu ua tunica media, uas muaj cov leeg du. Cov txheej sab hauv yog hu ua tunica intima. Tsis zoo li cov hlab ntsha, feem ntau cov hlab ntsha muaj ntau qhov kev hloov pauv ntawm lub cev. Qee cov hlab ntsha muaj li qub uas tiv thaiv regurgitation.
Venous System
Nerve and Vein yog dab tsi?
Txuas System:
Nerve: Nerves ua rau cov hlab ntsha ntawm lub paj hlwb.
Vein: Cov leeg ua rau cov hlab ntsha ntawm cov hlab ntsha.
qauv:
Nerve: Nerves yog tsim los ntawm axons thiab dendrites.
Vein: Cov leeg yog tsim los ntawm sab nrauv tunica adventitia, nruab nrab tunica media, thiab sab hauv tunica intima.
Function:
Nerve: Nerve yog qhov tseem ceeb rau kev ua haujlwm ntawm kev hnov lus.
Vein: Cov leeg nqa cov ntshav deoxygenated rau lub plawv.
Khoom thauj:
Nerve: Nerves thauj electrochemical pulses.
Vein: Veins thauj cov ntshav deoxygenated.
Kev sib txuas:
Nerve: Feem ntau cov hlab ntsha tsis sib cuam tshuam.
Vein: Txhua txoj hlab ntsha sib cuam tshuam.
