Abstract

Two types of ganglion cells are present in the cochlear ganglion of the alligator lizard. Myelinated cells are the predominant type but a small population of unmyelinated cells is also present. Ganglion cells are reconstructed and morphometrically analyzed from serial light and electron micrographs. The results are interpreted to indicate that the unmyelinated ganglion cells are degenerating neurons. No normal population of unmyelinated nerve fibers was found. The anatomy of the cochlear nerve of the lizard is described and compared with the mammalian auditory nerve.

摘要

短吻鳄蜥蜴的耳蜗神经节中存在两种类型的神经节细胞。有髓细胞是主要类型，但也存在少量无髓细胞。从连续的光学和电子显微照片中重建神经节细胞并进行形态计量分析。结果表明，无髓神经节细胞是正在退化的神经元。未发现正常的无髓神经纤维群体。描述了蜥蜴耳蜗神经的解剖结构，并与哺乳动物的听觉神经进行了比较。
