腹背的

Under the light microscope, the earliest TH-positivc cells at embryonic day 13 are localized at the ventral part of rostral midbrain. Later appearing TH-positive cells join the earlier ones dorsally and caudally.

最早的TH阳性细胞首先于胚胎13天在中脑吻端的腹侧出现；随后出现的TH阳性细胞从尾端和背侧逐渐加入早先出现的TH细胞。

First, the researchers assessed binocular vision. Using a dichoptic motion task to assess dorsal function and a dichoptic form task to assess ventral function, they were able to separate the signal and noise between the 2 eyes and to directly evaluate how well the organs combined the information. When comparable information was presented to each eye, amblyopic eyes made only a minor contribution to binocular performance.

首先，研究者评估双眼视力，使用双眼分开动作项目评估背侧功能，以双眼分开类型项目估计腹侧功能，可以在两眼之间分开讯号和噪音，直接评估器官如何合并讯息；当比较每个眼睛的讯息时，弱视的眼睛只是对双眼表现的镜象投射。

In addition, the South Korean researchers identified the maintenance of embryonic stem cells pluripotent Rap2GTPase gene in control of vertebrate dorsoventral axis structure of Nodal signal-regulated protein in the process of mechanism.

此外，韩国研究者查明了维持胚胎干细胞多能性的Rap2GTPase基因在控制脊椎动物背腹轴结构形成的Nodal蛋白质信号调节过程中的作用机理。

The dorsoventral movement of the tail produces the thrust, and bending of the anterior body in the horizontal plane enables turning maneuvers.

用一个串联的、多关节的上下摆动机构来实现背腹式运动，用左右摆动的转弯机构和两自由度运动的鳍肢机构来实现机动运动。

Analysis of PcG mutants shows that the PcG system represses genes required for anteroposterior, dorsoventral, and proximodistal patterning of imaginal discs and that it also represses cell cycle regulator genes.

对PcG突变体研究发现，PcG系统表达基因在幼虫发育的前端、背腹以及远端模式都是必须的，同时可抑制细胞分裂调节基因的活性。

The CGRP-positive fibers ran dorsoventrally in the MrD and formed a dense band. The CGRP-positive fibers were more densely and widely distributed in the caudal part of the MrD.

结果发现：（1）CGRP免疫阳性纤维在纹状体内存在于纹状体的中部和尾侧，位于尾壳核和苍白球之间，即相当于纹状体边缘区的部位，形成一条明显的背腹方向走行的带状。

Ovary with as many locules as sepals, rarely more, apex flat or conic, often with a depressed nectary surrounding base of each epipetalous stamen; stigma capitate or hemispheric, entire or lobed, upper 1/2-2/3 receptive.

子房室与萼片同数，很少更多，先端平或圆锥形，通常具一背腹扁平蜜腺围绕每个花瓣上着生的雄蕊的基部；柱头头状或半球形，全缘的或浅裂，上面的1/2-2/3有感受性。

The possible neurotransmitters mediating VLF-EPSPs were excitatory amino acids and non-NMDA receptors were critically involved in these synaptic transmissions,for both VLF-EPSP and glutamate-induced response were similary and almost completely abolished by kynurenic acid and DNQX.

提示VLF中的下行纤维可能与MN的胞体或近端树突形成突触，而背根或腹根中传入纤维与MN的远端树突联系。

The results show that the single-layered neural tube fails to form and the neural crest cells remain at the lateral regions in the explants with NTDs. However, the patterning of the neural tube is not affected as indicated by the normal expression of the preneural genes.

结果显示神经管闭合缺陷的移植体不能形成单层化的神经管，并且神经晴细胞滞留在侧面区域不能向背侧中线迁移，而对神经前体标记基因的检测显示神经管的背腹图式形成并未受到影响。

In addition to the pons positive neurons were also found in cerebellum, most nucleus of thalamus and hypothalamus, and corpus striatum of chicken.

鸡脑阳性神经元除广泛分布于脑干外，小脑、丘脑的多数核团、下丘脑的背侧核、腹侧核和后核以及大脑纹状体等多数脑区也有一定分布。
