Qhov sib txawv tseem ceeb ntawm Optic Nerve thiab Optic tract yog tias Optic paj hlwb yog cov paj hlwb uas txuas koj lub qhov muag mus rau lub hlwb thaum Optic tract yog ib feem ntawm qhov pom ntawm peb lub hlwb.
Qhov muag yog lub cev ntawm peb qhov muag pom. Qhov muag tso cai rau pom kev rau txhua tus, thiab nws muaj cov khoom sib txawv. Ntawm lawv, optical paj hlwb yog ib feem. Optic tract yog lwm qhov tseem ceeb ntawm qhov pom ntawm peb lub hlwb, uas yog txuas ntxiv ntawm cov paj hlwb.
Dab tsi yog Optic Nerve?
Cov paj hlwb optical yog cov paj hlwb uas nyob tom qab ntawm koj lub qhov muag. Nws ua haujlwm tshwj xeeb los coj peb lub zeem muag. Ntxiv mus, cov hlwb tshwj xeeb hauv retina tau txais lub teeb thiab hloov lub teeb rau hauv hluav taws xob impulses. Tom qab ntawd cov paj hlwb optical nqa cov impulses mus rau lub hlwb kom yooj yim rau kev pom.
Daim duab 01: Optical Nerve
Vim li no, cov paj hlwb optical yog ib feem ntawm koj lub qhov muag uas txuas nrog lub hlwb. Nws xa cov teeb liab mus rau lub hlwb thiab ua rau koj pom tej yam. Yog li ntawd, lub zeem muag ntawm lub paj hlwb tau txais cov ntaub ntawv pom los ntawm retina los ntawm cov hlab ntsha optical.

Optic Tract yog dab tsi?
Optic tract yog ib qho txuas ntxiv ntawm cov paj hlwb. Yog li ntawd, nws yog ib feem ntawm qhov pom ntawm lub hlwb. Qhov chaw kho qhov muag muaj ob lub ntsiab lus ntawm tus kheej; uas yog, txoj cai kho qhov muag thiab sab laug kho qhov muag. Sab laug kho qhov muag nqa cov ntaub ntawv los ntawm sab xis pom qhov chaw thaum txoj cai kho qhov muag nqa cov ntaub ntawv los ntawm sab laug qhov muag pom.
Daim duab 02: Optic Tract
Ob qho tib si kho qhov muag xaus ntawm lub lateral geniculate nucleus hauv thalamus. Cov kab mob optic muaj fibers uas los ntawm ipsilateral temporal hemiretina thiab contralateral nasal hemiretina.
Dab tsi zoo sib xws ntawm Optic Nerve thiab Optic Tract?
- Optic paj hlwb thiab kho qhov muag yog ob yam ntawm peb qhov muag pom.
- Ob leeg nqa cov ntaub ntawv pom rau lub hlwb.
- Ob leeg Optic Nerve thiab Optic Tract yog qhov tseem ceeb heev rau kev pom.
Qhov txawv ntawm Optic Nerve thiab Optic Tract yog dab tsi?
Cov paj hlwb yog cov paj hlwb uas txuas koj lub qhov muag mus rau lub hlwb thaum lub qhov muag kho qhov muag yog qhov txuas ntxiv ntawm cov paj hlwb. Yog li ntawd, qhov kho qhov muag yog ib feem ntawm qhov pom ntawm lub hlwb. Qhov no yog qhov sib txawv tseem ceeb ntawm lub paj hlwb thiab lub paj hlwb. Tsis tas li ntawd, cov hlab ntsha kho qhov muag nyob hauv qab ntawm lub qhov muag thaum lub qhov muag pom nyob hauv lub hlwb.
Summary – Optic Nerve vs Optic Tract
