运动神经元

Light and electron microscopy showed central chromatolysis of motor neurons in the lumbar cord from 1 week after the start of compression.

研究结果：光学和电子显微镜检查表明从压迫1周后出现腰髓运动神经元的中心染色质溶解。3周后，在前角可见到一些神经元的凋亡。

ABSTRACT The present study was performed to explore the effect of endogenous nitric oxide on synaptic transmission between neurons located in Forel′s field H and vertical oculomotoneurons innervating the inferior oblique muscle in cats.

本研究探讨内源性一氧化氮对猫中脑。间脑结合部Forel′s field H区神经元与下斜肌(inferior oblique， IO)眼球运动神经元(oculomotoneurons， OMNs)之间兴奋性突触传递的影响。

A way of blocking the activity of specific pain-sensing neurons without affecting other sensory or motor neurons could be used to create a more targeted form of local anaesthesia, and that is the prospect held out by Binshtok et al. in this issue.

一种阻断特定痛觉神经元的这种活性而又不影响其他感觉或运动神经元的方法，也许可用来创建一种目标性更强的局部麻醉方法，而这正是Binshtok等人在本期Nature上提出的一个观点。

GDNF has been reported to exhibit trophic actions on various neurons of central nervous system and peripheral nervous system .

GDNF对中枢及外周的多种神经元有神经营养作用，与目前已知的神经营养因子相比，GDNF对受到损伤的多巴胺能神经元和运动神经元的促存活作用最为显著。

Alpha motor neurons that innervate muscle fibers are located in the ventral horns of the spinal cord, and comprise the efferent limb of this reflex arc.

这是一个单突触反射通路，运动依赖感受器的反馈，间接的Ⅰa传入纤维也在后角与抑制的中间神经元突触，这就能通过依次激活与α运动神经元连接的拮抗肌来抑制主动肌的紧张。

Results Following HRP injection into uvala muscles, labeled motoneurons were located in the rostral section of nucleus ambiguus.

结果 悬雍垂肌的运动神经元位于同侧疑核中；切断一侧副神经延脑根后，疑核内的标记神经元消失。

There are several descending central nervous system pathways that synapse directly or indirectly on motor neurons and allow for suprasegmental control of movement .

这个通路考虑了对于精细动作和粗大动作来说协调主动肌和拮抗肌都是必须的，在下位中枢有几条直接或通过中间神经元与运动神经元突触的通路，考虑可能与跨节段控制运动有关。

Barrington's nucleus that located in the pontine dorsolateral tegmentum is an important site for controlling voiding in the mammalian brain and is often referred to as pontine micturition center. Barrington's nucleus sends direct projection fibers to the sacral parasympathetic nucleus in which parasympathetic preganglionic neurons innervating detrusor muscles of the bladder are distributed. Electron or chemical stimulation of Barrington's nucleus clicits bladder contraction and increases discharges of bladder postganglionic nerve. Conversely, lesion of the nucleus results in a permanent inability to empty the bladder. On the other hand, an area located just ventral to Barrington's nucleu has been reported to send projection fibers to the ventrolateral group of Onuf's nucleus in the caudal lumbar cord segments; the vetrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.

Barrington's核发出纤维投射至支配膀胱逼尿肌的骶髓副交感核，毁损该区可导致动物永久性失去排空膀胱的能力；而电刺激或化学刺激该区可引起支配膀胱的节后纤维放电增加和膀胱逼尿肌收缩。D区是紧邻Barrington's核腹侧的一团神经元，它发出纤维投射至腰骶髓Ounf核的腹外侧群，而Ounf核的腹外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

The MNs innervating homo-meridian have relative independent locations in spinal cord.

支配同一经络的运动神经元在脊髓中枢有相对独立的分布区域，沿脊髓长轴形成运动神经元柱。
