Abstract:
The cytoarchitecture of the parasympathetic oculomotor nucleus in the buffalo has been described by materials collected from eight buffalos. Serial and semi serial sections of brain stem were used for the study. The parasympathetic oculomotor nucleus was composed primarily of small and medium sized fusiform cells. The neurons had prominent nucleus with central or eccentric nucleolus and a small amount of cytoplasm. Coarse clumps of deeply stained Nissl substance was distributed in the scarce cytoplasm. The mean neuron population in the nucleus was 18,834. In the nucleus the mean diameter of medium sized neurons was 29.87 ± 0.41 μm and that of small sized neurons was 23.1 ± 0.29 μm.
