The synaptic morphology of inner and outer hair cells of the organ of Corti of the chimpanzee was evaluated by serial section electron microscopy. The morphology of nerve terminals and synapses at both sites was very similar to that of human and other mammalian species. Two types of nerve terminals, nonvesiculated and vesiculated, with distinct synaptic morphology were found. In addition, between some nonvesiculated endings and outer hair cells, a reciprocal synaptic relationship was seen. In such terminals there was morphologic evidence for transmission from hair cell to neuron and from neuron to hair cell between a single neuron and an outer hair cell.
通过连续切片电子显微镜评估了黑猩猩柯蒂氏器内、外毛细胞的突触形态。这两个部位的神经末梢和突触形态与人类及其他哺乳动物非常相似。发现了两种具有不同突触形态的神经末梢，即无囊泡型和有囊泡型。此外，在一些无囊泡末梢与外毛细胞之间，可见相互的突触关系。在这样的末梢中，有形态学证据表明在单个神经元与外毛细胞之间存在从毛细胞到神经元以及从神经元到毛细胞的传递。
