The histomorphological observations are made on the Mauthner cells in eight species of teleosts belonging to six different families. The cells are better developed in Channa punctatus, Heteropneustes fossilis, Labeo rohita, Danio, malabaricus and Puntius ticto. They are symmetrically situated in Nandus nandus and are found to be absent in Mastocembalus armatus. Their position, shape and size vary in different species. The axon cap is well developed in Channa punctatus, Heteropneustes fossilis and carps. The cell body sends lateral and ventral dendrites besides several small dendrites. The lateral dendrite emerges through the axon cap, turns dorsolateral and becomes myelinated to form Mauthner axon. The Mauthner axon extends in the spinal region upto the caudal peduncle and forms synapses with the spinal motoneurons of the front column. There are numerous synapses and end bulbs from the vestibular fibres and VIIIth nerve distributed on the perikaryan of the Mauthner cell body. It is suggested that the Mauthner cells are comparatively well developed in those species in which the tail fin is better utilized for swimming.
对六个不同科的八种硬骨鱼的Mauthner细胞进行了组织形态学观察。这些细胞在斑鳢、胡鲶、露斯塔野鲮、斑马鱼、马拉巴丽鱼和蒂氏无须魮中发育较好。它们在南鲈中对称分布，而在无斑长臀鮠中未发现。它们的位置、形状和大小在不同物种中有所不同。轴突帽在斑鳢、胡鲶和鲤科鱼类中发育良好。细胞体除了发出几个小的树突外，还发出侧向和腹侧树突。侧向树突穿过轴突帽，转向背外侧并髓鞘化形成Mauthner轴突。Mauthner轴突在脊髓区域延伸至尾柄，并与前柱的脊髓运动神经元形成突触。在前庭纤维和第VIII神经上有许多突触和终球分布在Mauthner细胞体的核周。有人认为，在那些更好地利用尾鳍游泳的物种中，Mauthner细胞发育得相对较好。
