Nyob zoo! Koj nyob li cas? Hnub no peb yuav tham txog ib txoj hlab ntsha uas tseem ceeb heev rau peb lub qhov muag, tab sis tej zaum peb tsis tau hnov ntau txog nws. Qhov no yog txoj hlab ntsha trochlear, lossis raws li nws hu ua lus Askiv '(Trochlear Nerve)'. Qhov no yog ib txoj hlab ntsha me me tab sis tseem ceeb heev uas pab peb lub qhov muag txav mus los, tshwj xeeb tshaj yog thaum saib mus rau hauv qab. Cia peb saib ntxiv txog qhov no, puas yog?
Lub paj hlwb Trochlear yog dab tsi?
Hais yooj yim xwb, cov hlab ntsha trochlear zoo li ib txoj hlua me me uas nqa cov lus los ntawm peb lub hlwb mus rau peb lub qhov muag. Koj puas paub tias muaj 12 pawg ntawm cov hlab ntsha hauv peb lub taub hau, uas peb hu ua cov hlab ntsha cranial? Cov hlab ntsha trochlear yog plaub ntawm kaum ob (tseem hu ua Cranial Nerve 4 lossis CN IV).
Qee cov hlab ntsha hauv peb lub cev pab peb hnov tej yam xws li kev kov thiab kub (kev xav), thaum lwm tus pab peb tswj kev txav mus los. Txawm li cas los xij, txoj haujlwm tseem ceeb ntawm cov hlab ntsha trochlear no yog tswj peb lub qhov muag txav mus los. Ntawd yog, nws yog cov hlab ntsha tsav tsheb, lossis cov hlab ntsha kinesthetic. Peb muaj ob lub hlab ntsha trochlear no, ib qho rau txhua lub qhov muag.
Cov hlab ntsha no ua dab tsi tiag?
Zoo, tam sim no cia peb saib seb cov hlab ntsha me me no ua dab tsi tiag. Cov hlab ntsha trochlear muaj ib txoj haujlwm tseem ceeb. Thiab qhov ntawd yog xa cov lus mus rau ib cov leeg tshwj xeeb hauv peb lub qhov muag, cov leeg nqaij sab saud, kom txav nws.
Cov hlab ntsha trochlear no, nrog rau cov leeg nqaij "superior oblique" uas kuv tau hais, ua ke tso cai rau peb ua cov no:
- Saib rau hauv qab: Ob qho no ua ke coj koj ob lub qhov muag mus rau hauv qab, xws li thaum koj nyeem phau ntawv lossis nqis ntaiv.

- Tig koj ob lub qhov muag deb ntawm koj lub qhov ntswg (sab nraud).
Puas yog nws tsis zoo kawg li? Lub npe "trochlea" los ntawm lo lus Latin "trochleae," uas txhais tau tias "pulley." Lub pulley yog ib yam dab tsi uas pab tsa lossis txo qee yam. Cov leeg nqaij sab saud, uas tswj cov hlab ntsha no, txuas nrog peb lub qhov muag ntawm sab saum toj ntawm pob muag. Cov leeg no khiav dhau ib txoj hlua ntawm cov ntaub so ntswg sib txuas, uas ua haujlwm zoo li lub pulley. Yog vim li ntawd nws thiaj li tau txais nws lub npe.
Xav txog seb, ib yam li ib txoj hlua khi hla lub pulley thiab rub ib qho hnyav, cov hlab ntsha thiab cov leeg no ua haujlwm ua ke los tig peb lub qhov muag mus rau hauv qab.
Muaj ob peb lwm cov hlab ntsha uas pab txav lub qhov muag:
- Cov hlab ntsha Oculomotor (CN III)
- Cov hlab ntsha Abducens (CN VI)
- Cov hlab ntsha ntawm lub ntsej muag (CN VII) (Qhov no kuj koom nrog rau tej yam xws li kaw qhov muag)
Koj puas paub qhov twg cov hlab ntsha trochlear nyob?
Cov hlab ntsha trochlear (CN IV) no tsuas yog tswj ib leeg xwb, tab sis nws yuav tsum taug kev ntev me ntsis kom mus txog cov leeg ntawd. Xav txog, txawm tias nws me me, nws yog ib txoj kev nyuaj me ntsis.
Cov hlab ntsha no pib hauv peb lub hlwb . Tom qab ntawd, ua ntej txuas mus rau cov leeg nqaij sab saud ntawm sab saum toj ntawm lub pob muag, nws hla dhau plaub qhov chaw tseem ceeb. Cov no yog:
1. Trochlear nucleus: Qhov no yog ib feem ntawm cov hlab ntsha trochlear uas nyob ze tshaj plaws rau lub hlwb. Nws nyob rau sab saum toj ntawm lub hlwb.
2. Ambient cistern: Thaj chaw no nyob ze ntawm daim nyias nyias uas nyob ib puag ncig lub hlwb (hu ua dura mater, ib feem ntawm peb cov meninges).
3. Qhov ntswg qhov quav: Qhov no yog qhov chaw zoo li qhov quav nyob hauv nruab nrab ntawm peb lub taub hau.
4. Lub voj voog: Qhov no yog qhov pob txha hauv lub taub hau uas peb lub qhov muag nyob. Tom qab dhau los ntawm lub voj voog, cov hlab ntsha trochlear txuas nrog cov leeg nqaij oblique sab saud.
Koj puas tau pom pes tsawg qhov chaw uas cov hlab ntsha me me no tau dhau los ua nws txoj haujlwm?
Yuav ua li cas yog tias cov hlab ntsha trochlear raug puas tsuaj?
Tu siab kawg li, yog tias muaj kev puas tsuaj rau cov hlab ntsha trochlear no, nws tuaj yeem cuam tshuam rau peb qhov muag pom kev thiab txoj kev uas peb txav peb lub qhov muag. Cov kws kho mob hu qhov no ua mob plawv thib plaub lossis mob plawv trochlear .
Nov yog cov tsos mob feem ntau ntawm tus mob no:
- Pom ob sab (diplopia): Pom ob yam tib lub sijhawm. Qhov no tuaj yeem ua rau mob hnyav dua thaum saib rau hauv qab.
