Qhov Tseem Ceeb - Nerves vs Ntshav
Lub paj hlwb thiab cov hlab ntsha yog ob lub cev tseem ceeb hauv peb lub cev. Lub paj hlwb yog lub luag haujlwm rau kev xa cov hluav taws xob hluav taws xob los yog cov paj hlwb impulses thaum lub circulatory system yog lub luag hauj lwm rau kev thauj mus los ntawm cov ntshav sib xyaw nrog oxygen, carbon dioxide, as-ham, cov tshuaj hormones thiab cov khoom pov tseg thoob plaws hauv lub cev. Cov paj hlwb lossis cov neurons yog cov haujlwm tseem ceeb ntawm lub paj hlwb. Cov paj hlwb yog cov hlwb tshwj xeeb uas tau txais, txheej txheem thiab xa cov ntaub ntawv los ntawm lub cev mus rau lub hlwb thiab rov qab mus rau lub cev. Cov hlab ntsha yog ib feem ntawm peb lub ntsiab ntawm cov hlab ntsha. Cov hlab ntsha xa cov ntshav mus rau thiab los ntawm lub plawv mus rau thiab los ntawm tag nrho lub cev. Cov hlab ntsha ua lub network ntawm cov hlab kaw kom nqa cov ntshav hauv lub cev. Muaj peb yam tseem ceeb ntawm cov hlab ntsha uas yog, cov hlab ntsha, capillaries, thiab cov hlab ntsha. Qhov sib txawv tseem ceeb ntawm cov hlab ntsha thiab cov hlab ntsha yog tias, cov hlab ntsha xa hluav taws xob xaim hluav taws xob thaum cov hlab ntsha thauj cov ntshav thoob plaws hauv lub cev.
Nerves yog dab tsi?
Ib neuron yog lub luag haujlwm tseem ceeb ntawm peb lub paj hlwb uas nqa cov paj hlwb. Neurons yog cov paj hlwb tshwj xeeb uas tau txais, txheej txheem thiab xa cov ntaub ntawv los ntawm lub cev mus rau lub hlwb thiab rov qab mus rau lub cev. Muaj 10 txog 100 billion neurons hauv peb lub paj hlwb. Neurons tsis rov tsim dua. Kwv yees li 10000 neurons tuag txhua hnub los ntawm peb lub cev. Cov hlab ntsha yog tsim los ntawm peb lub ntsiab lus; cell lub cev, dendrites thiab axon. Dendrites tau txais cov lus los ntawm lwm cov neurons thiab dhau ntawm lub cev ntawm tes mus rau axons. Axons hloov cov teeb liab hluav taws xob rau hauv cov teeb liab tshuaj lom neeg thiab xa mus rau cov neuron tom ntej los ntawm cov synapse siv cov tshuaj hu ua neurotransmitters. Dendrites ntawm cov neuron tom ntej hloov cov teeb liab tshuaj ntxiv rau hauv cov teeb liab hluav taws xob thiab hla nws cov axon mus rau cov nyees khawm. Ib yam li ntawd, cov ntaub ntawv raug xa mus los ntawm cov neurons thoob plaws hauv lub cev mus rau hauv lub cev, cov qog, cov leeg thiab mus rau lwm cov neurons.
Daim duab 01: Nerves
Muaj peb hom hlab ntsha; cov paj hlwb, cov paj hlwb, thiab cov paj hlwb relay. Cov hlab ntsha ntawm lub paj hlwb nqa cov teeb liab electrochemical los ntawm cov kab mob hauv lub cev mus rau hauv nruab nrab paj hlwb. Relay paj hlwb nqa cov teeb liab los ntawm ib feem ntawm lub hauv nruab nrab paj hlwb mus rau lwm qhov ntawm nws. Lub cev muaj zog cov hlab ntsha nqa cov teeb liab los ntawm lub hauv nruab nrab lub paj hlwb mus rau lub cev muaj zog. Feem ntau ntawm cov hlab ntsha tau txhawb nqa los ntawm Schwann hlwb. Schwann hlwb nce qhov ua tau zoo ntawm cov hlab ntsha pulse kis mus rau cov paj hlwb los ntawm kev tsim cov khoom muaj roj hu ua myelin thiab qhwv ib ncig ntawm axons.
Cov hlab ntsha yog dab tsi?
Lub circulatory system yog ib qho ntawm peb lub cev tseem ceeb uas thauj cov ntshav, roj, cov tshuaj hormones, cov as-ham thoob plaws hauv lub cev. Lub plawv, ntshav, thiab cov hlab ntsha yog cov ntsiab lus tseem ceeb ntawm tib neeg cov hlab plawv, thiab nws yog lub kaw lus kaw uas cov ntshav ncig tsuas yog nyob rau hauv lub network ntawm cov hlab ntsha uas hu ua cov hlab ntsha. Cov hlab ntsha nqa ntshav mus rau lub plawv thiab thaum kawg mus rau txhua qhov ntawm lub cev. Cov hlab ntsha yog peb hom loj; Cov hlab ntsha, capillaries, thiab leeg. Cov hlab ntsha nqa oxygenated ntshav los ntawm lub plawv mus rau tag nrho lwm cov ntaub so ntswg ntawm lub cev. Capillaries yog cov hlab ntsha me me uas pab txhawb kev sib pauv ntawm oxygen, as-ham, thiab khib nyiab ntawm cov ntshav thiab cov ntaub so ntswg. Cov leeg nqa cov ntshav uas tsis muaj oxygen los ntawm cov ntaub so ntswg mus rau lub plawv.
Daim duab 02: Cov Ntshav
Cov hlab ntsha thiab cov hlab ntsha yog tsim los ntawm peb txheej ntawm tes hu ua tunica intima, tunica media, thiab tunica adventitia. Cov phab ntsa ntawm cov hlab ntsha yog tuab dua li cov phab ntsa ntawm cov hlab ntsha vim cov ntshav siab uas muaj nyob hauv cov hlab ntsha. Cov leeg muaj txoj kab uas hla loj dua cov hlab ntsha.
Dab tsi zoo sib xws ntawm Nerves thiab hlab ntsha?
- Ob leeg cov hlab ntsha thiab cov hlab ntsha yog ntev thiab nyias.
- Ob leeg ua haujlwm thauj.
- Ob leeg yog cov channel tseem ceeb hauv lub cev.
- Ob leeg hlab ntsha thiab cov hlab ntsha nyob thoob plaws lub cev.
- Cov hlab ntsha thiab cov hlab ntsha mus ua ke hauv yuav luag txhua cov ntaub so ntswg hauv lub cev.
- Ob leeg yog cov qauv uas muaj ceg tawv heev.

Summary – Nerves vs Blood Vessels
Nerves lossis neurons yog cov hlwb tshwj xeeb uas xa cov cim thoob plaws lub cev. Lawv yog cov yooj yim functional units ntawm lub paj hlwb. Cov hlab ntsha yog cov li qub uas xa cov ntshav thoob plaws hauv lub cev. Cov hlab ntsha thiab cov hlab ntsha khiav ua ke hauv tag nrho cov ntaub so ntswg hauv peb lub cev. Cov hlab ntsha xa cov teeb liab electrochemical thaum cov hlab ntsha xa cov ntshav sib xyaw nrog cov khoom noj khoom haus, cov tshuaj hormones, gasses, thiab cov khoom pov tseg. Qhov no yog qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha.
