目的和方法 :应用 HRP逆行标记法和图像分析法 ,对大鼠展神经核运动神经元和核间神经元的分布、数量及形态、大小进行了观察。结果 :大鼠的展神经核间神经元主要集中在展神经核的吻侧 2 / 3,和腹外侧区 ;运动神经核则位于展神经核的背内侧区 ,仅在展神经核的中央 ,两种神经元有少量的混合。运动神经元和核间神经元的比例为 2∶ 1。大多数核间神经元呈小梭形 ,少数和运动神经元相似为较大的圆形或锥形。结论 :大鼠展神经核运动神经元和核间神经元具有特殊分布形形式
PURPOSE AND METHODS: The distribution, number, morphology, and size of motor neurons and nucleus neurons in the dorsal radicular nerve nucleus were observed using HRP retrograde labeling and image analysis. Results: The interneurons in the Spinal nerve of the rats mainly concentrated in the kyphosis 2/3, and the ventrolateral region of the Spinal cord nucleus. The motor nerve nucleus was located in the dorsal medial region of the Spindle, There is a small amount of mixing between the two neurons. Motor neurons and nuclear neurons in the ratio of 2: 1. Most of the nucleus neurons are fusiform, a small number and motor neurons similar to a larger circle or cone. Conclusion: The motor neurons and nucleus neurons of the SPF have a special distribution pattern
