There are medullary reticular nucleus, reticular gigantocellular nucleus, lateral reticular nucleus and raphe nuclei.The raphe nuclei can be divided into three subnuclei: nucleus raphe obscurus, nucleus raphe pallidus and nucleus raphe magnus. The reticular formation nuclei contain heterogeneous population of neurons, which vary in size and shape. Cells with abundant processes are in the shape of ellipse, fusiform, polygon and triangle. Small cells are little. Cell nucleus are in the middle or at the side of the cell appeared rotundity or ellipse. Nucleolus is clear. The results indicate that the reticular nucleus cytoarchitecture of medullary reticular formation of African ostrich is not much different from other birds, except relatively less nuclei, larger cell and more abundant processes; there are some differences in raphe nuclei.展开更多
