The spinal cord of goldfish (Carassius auratus) was examined in normal and experimental animals by light and electron microscopy. Comparisons of Golgi material and electron micrographs have shown the large ventral horn motoneurons to have dendrites with few spines. The axon may arise from a ventral dendrite. Synapses on the motoneuron may be chemical or combined electrotinic and chemical or electrotonic between dendrites. Transection of the cord produced degeneration of small boutons, but large boutons remained intact. Small boutons were found on dorsal root axons and large boutons on interneurons in Golgi preparations. Boutons en passant may arise from myelinated fibers.
通过光学显微镜和电子显微镜对正常和实验动物的金鱼（Carassius auratus）脊髓进行了检查。高尔基材料和电子显微照片的比较表明，大的腹角运动神经元的树突棘很少。轴突可能起源于腹侧树突。运动神经元上的突触可能是化学性的，或者是电突触和化学突触相结合的，或者是树突之间的电突触。脊髓横断导致小终扣变性，但大终扣保持完整。在高尔基制剂中，在背根轴突上发现了小终扣，在中间神经元上发现了大终扣。中途终扣可能起源于有髓纤维。
