用扫描电子显微镜对鸡胚睫状神经节内的突触前神经末梢进行了三维观察。不发达的神经末梢附着在纤毛细胞的外侧，呈勺状，表面纹理不规则，边缘轮廓多，有许多细长的突起和毛孔。发达的神经末梢包裹着纤毛细胞表面的一半以上，呈杯状，表面纹理光滑，边缘线形，很少有细长的突起和毛孔。细长的突起在勺状神经末梢的边缘相互亲密接触，或穿过毛孔，似乎扩张和平滑神经末梢。纤毛细胞的胞质突起也被描述。
Presynaptic nerve endings in the ciliary ganglia of chick embryos are 3-dimensionally examined by scanning electron microscopy. Underdeveloped nerve endings attached to the lateral side of the ciliary cells are spoon-like, and show an irregular surface texture and marginal outline with many slender processes and pores. Well-developed nerve endings embracing more than half of the surface of the ciliary cell are cup-like, and show a smooth surface texture and a linear marginal outline with few slender processes and pores. The slender processes come into intimate contact with each other at the margin of the spoon-like nerve endings or cross the pores, seemingly expanding and smoothing the nerve endings. Cytoplasmic processes of the ciliary cells are also described.
