Qhov sib txawv tseem ceeb ntawm telencephalon thiab diencephalon yog tias telencephalon yog qhov chaw sab hauv ntawm lub hlwb, uas tseem hu ua cerebrum, thaum diencephalon yog ib feem ntawm lub hlwb uas muab tso rau ntawm telencephalon thiab midbrain.
Lub hlwb muaj cerebrum, cerebellum thiab medulla oblongata. Lub cerebrum, tseem hu ua telencephalon, belongs rau anterior ib feem ntawm lub hlwb. Nws yog qhov loj tshaj plaws ntawm lub hlwb. Ntxiv mus, nws yog lub Uppermost cheeb tsam ntawm lub hlwb. Diencephalon yog ib feem ntawm lub forebrain nyob nruab nrab ntawm telencephalon thiab midbrain. Nws yog ib qho tseem ceeb kom nkag siab txog kev ua haujlwm ntawm telencephalon thiab diencephalon uas ua rau lub hlwb anterior.
Telencephalon yog dab tsi?
Telencephalon tseem hu ua cerebrum. Nws yog qhov loj tshaj plaws ntawm lub hlwb thiab kwv yees li ntawm 85% ntawm tag nrho qhov hnyav ntawm lub hlwb. Lub telencephalon muaj lub paj hlwb hemisphere: sab laug thiab sab xis cerebral hemispheres. Lub cerebellum nyob hauv qab lub telencephalon.
Lub telencephalon txhim kho thaum lub sij hawm 5th lub lim tiam ntawm kev loj hlob ntawm embryonic. Nws tsim los ntawm cov hlab ntsha neural, qhov kawg kawg ntawm cov hlab ntsha neural loj hlob mus rau hauv lub telencephalon. Thaum lub sij hawm kev loj hlob ntawm lub telencephalon, kev loj hlob ntawm sulci thiab gyri tshwm sim. Ntxiv mus, cerebral cortex pib tshwm, tsim ib thaj tsam rau lub telencephalon. Lub cortex nyob ib ncig ntawm lub telencephalon muaj lub prefrontal cortex, lub cev muaj zog cortex, somatosensory cortex thiab occipital cortex. Nws kuj muaj cov qauv subcortical.
Daim duab 01: Telencephalon
Lub luag haujlwm ntawm telencephalon sib txawv. Nws yog lub ntsiab lus tseem ceeb ntawm lub hlwb uas cuam tshuam nrog feem ntau ntawm lub hlwb ua haujlwm. Sib nrug los ntawm kev sib koom tes ntawm lub hlwb, nws tseem ceeb heev rau kev paub txog kev hnov lus, olfaction, lus thiab kev hais lus, kev kawm thiab kev nco.
Diencephalon yog dab tsi?
Diencephalon tsim ib feem ntawm lub forebrain. Nws nyob nruab nrab ntawm lub telencephalon thiab midbrain. Nws muaj ntau yam qauv hauv. Lawv yog cov thalamus, thiab hypothalamus nrog rau lub posterior pituitary, epithalamus, subthalamus thiab pineal lub cev. Tsis tas li ntawd, cov hlab ntsha optic tseem txuas nrog ntawm diencephalon. Thiab, nws yog cov hlab ntsha tseem ceeb uas koom nrog hauv kev pom, nrog kev pab ntawm cov pas nrig thiab cov pob txha hauv lub retina. Cov ntaub ntawv diencephalon thaum lub sij hawm 3 rdlub lim tiam ntawm kev loj hlob embryonic. Lub diencephalon kuj tshwm sim los ntawm neural raj.
Daim duab 02: Diencephalon
Diencephalon lub luag haujlwm tseem ceeb yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm. Yog li, hypothalamus yog qhov tseem ceeb hauv kev tswj hwm homeostasis. Lub thalamus ua haujlwm hauv kev sib txuas lus thiab lub cev muaj zog impulses ntawm tus txha caj qaum thiab medulla oblongata.
Dab tsi zoo sib xws ntawm Telencephalon thiab Diencephalon?
-
- Kev loj hlob ntawm ob qhov chaw tshwm sim thaum lub sij hawm embryonic kev loj hlob.
- Ntxiv mus, cov hlab ntsha neural tsim, thiab sib txawv rau hauv ob qho tib si.
- Ob leeg yog ib feem ntawm lub hlwb anterior.
- Lawv koom nrog kev paub paub thiab lub hlwb ua haujlwm.
Qhov txawv ntawm Telencephalon thiab Diencephalon yog dab tsi?
Telencephalon yog qhov loj tshaj plaws thiab thaj tsam sab saud ntawm lub hlwb. Meanwhile, diencephalon yog ib feem ntawm lub forebrain nyob nruab nrab ntawm telencephalon thiab midbrain. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm telencephalon thiab diencephalon. Telencephalon thiab diencephalon txoj kev loj hlob pib thaum lub sij hawm embryonic txoj kev loj hlob. Qhov ntawd yog; diencephalon loj hlob thaum lub sij hawm 3rd lub lim tiam thaum lub telencephalon loj hlob thaum lub sij hawm 5th week.
Tsis tas li ntawd, nyob ntawm cov qauv tsim txhua ntu muaj, kev ua haujlwm ntawm ob qho tib si telencephalon thiab diencephalon kuj txawv. Telencephalon yog ib qho tseem ceeb rau kev paub txog kev paub, kev paub, lus, kev hais lus, kev kawm thiab kev nco. Lub caij no, diencephalon tseem ceeb heev rau homeostasis, kev paub txog kev hnov qab thiab pom qhov pom. Yog li, qhov no yog lwm qhov sib txawv ntawm telencephalon thiab diencephalon.
Summary – Telencephalon vs Diencephalon
Telencephalon thiab diencephalon tsim lub hlwb lub cev nyob rau hauv kev sib raug zoo rau lub anterior ntawm lub hlwb. Lub telencephalon yog qhov tseem ceeb tshaj plaws ntawm lub hlwb, thiab nws tseem hu ua cerebrum. Meanwhile, lub diencephalon yog ib feem ntawm lub telencephalon thiab lub midbrain. Txawm hais tias ob qho tib si nquag koom nrog hauv kev sib kis ntawm kev hnov lus, lawv txawv ntawm lawv cov haujlwm tshwj xeeb raws li qhov sib txawv lawv muaj. Yog li, nws yog ib qho tseem ceeb kom nkag siab txog cov ntsiab lus ntawm ob qho tib si telencephalon thiab diencephalon kom nkag siab txog cov haujlwm tshwj xeeb ntawm txhua tus.
