The nerves in and immediately under the epithelial layer of the trachea and primary bronchi of the cat are studied with the electron microscope. The axons are unmyelinated and contain microtubules and mitochondria. Epithelial axons are observed throughout the entire epithelial layer, but, are usually concentrated in the basal area immediately above the basal lamina. Most axons are near the basal cells; others are in the vicinity of granulated cells or occur in the intercellular spaces between other columnar cells. A few of the epithelial axons are large and crowded with axoplasmic mitochondria. The possibility that some epithelial axons may have sensory functions is discussed.
用电子显微镜研究了猫气管和初级支气管上皮层内及紧邻上皮层下方的神经。轴突无髓鞘，含有微管和线粒体。上皮轴突见于整个上皮层，但通常集中在基膜上方紧邻的基底部区域。大多数轴突靠近基底细胞；其他轴突位于颗粒细胞附近或在其他柱状细胞之间的细胞间隙中。少数上皮轴突较粗大，充满轴浆线粒体。文中讨论了一些上皮轴突可能具有感觉功能的可能性。
