神经核团的立体定位与立体构形的实验研究

EXPERIMENTAL RESEARCH ON STEREO LOCALIZA TION AND STEREO FORMATION OF NERVOUS NUCLEUS

对树中缝背核（ＮｕｃｌｅｕｓＲａｐｈｅＤｏｒｓａｌｉｓ，ＮＲＤ）的立体定位、立体构形和细胞构筑进行研究，结果：ＮＲＤ在ＡＰＯ平面前（０．２７±０．０８）ｍｍ出现，至ＡＰＯ平面后（１．１２±０．０９）ｍｍ消失；ＮＲＤ背侧顶点在ＨＯ平面上（１．６８±０．０６）ｍｍ，腹侧低点在ＨＯ平面下（０．９７±０．０５）ｍｍ；ＮＲＤ左右侧最宽处在ＭＳ平面外（０．５０±０．０４）ｍｍ。根据树ＮＲＤ的形态变化，重塑了它的立体构形。树ＮＲＤ的细胞构筑与其它哺乳类动物的ＮＲＤ细胞构筑大体相似。

This experiment dealt with the stereo localization,stereo formation and cytoarchitecture of nucleus raphe dorsalis(NRD) in the brain stem of the tupaia The results were as follows:NRD appeared at(0 27±0 08)mm before the APO plane,and disappeared at(1 12±0 09)mm behind the APO plane;the most dorsal point of NRD was at(1 68±0 06)mm above the HO plane,while the most ventral point of NRD was at(0 97±0 05)mm below the HO plane;and the widest point was at(0 50±0 04)mm apart from the MS plane The stereo formation of tupaia's NRD was also made according to their changing shape The cytoarchitecture of tupaia's NRD was similar to those observed in other mammal animals
