滑车神经的应用显微解剖研究

Microsurgical Anatomy of Trochlear Nerve

血管密度较高的核团有下丘核、动眼神经核、滑车神经核和红核；

The high density nuclei are inferior collicular nucleus , oculomotor nucleus , trochlear nucleus and red nucleus .

其中外展神经麻痹4例，不完全性动眼神经麻痹2例，滑车神经麻痹1例。

Of them had abducens paralysis ; 2 cases suffered from oculomotor paresis and 1 had trochlear paralysis .

滑车神经、额神经、泪腺神经及眼上静脉经外侧区穿行。

The lateral sector is pass by the trochlear , frontal and lacrimal nerves and the superior ophthalmic vein .

动眼神经、滑车神经和展神经各分支在神经干内定位的初步观察

Preliminary Observation on the Localization of the Branches of the Oculomotor Trochlear and Abducent Nerves in the Nerves Trunk

在窦的中部，位于滑车神经内侧4.5±2.1mm。

The nerve lay in 4.5 ± 2.1 mm medial to trochlear nerve in the middle part of cavernous sinus .

以及测量动眼神经、滑车神经、三叉神经、展神经、面神经脑池段。

And measure the cisternal segment of oculomotor nerve , trochlear nerve , trigeminal nerve , abducent nerve and facial nerve .

颈内动脉鞘亦可以作为动眼神经入口和滑车神经入口的标志点。

The sheath of internal carotid artery is also the landmark for the entrance site of the oculomotor and trochlear nerve .

用组织学方法对7只成年健康科尔沁细毛羊滑车神经核与动眼神经核的形态、位置和细胞构筑进行了研究。

Morphology and cytoarchitecture of nucleus nervi trochlearis and nucleus nervi oculomotorii of7 adult health Keerqin fine-wool sheep were studied using histological method .

后岩床皱襞与小脑幕缘的交点为标志点可定位滑车神经入小脑幕点。

The point of intersection of post bedrock folds and tentorial edge can be targeted the point of Trochlear nerve into the tentorial .

中等密度淡染的阳性神经元胞体、纤维和终末见于动眼神经核、滑车神经核和舌下神经核；
