Two intranasal biopsies of human olfactory mucosa were studied with the electron microscope, after confirming with the light microscope that they were in fact from the olfactory region. It was noted that the end of the dendrite of the human olfactory cell is flat or dome-shaped, and is not a bulb-like projection (olfactory vesicle). Moreover, the cilia are in the long axis of the olfactory cell, perpendicular to the epithelial surface, and do not lie parallel to it as described in some species. The supporting cells had multiple long microvilli, and definite points of contact with the olfactory cells; they appeared to spread their secretion over the microvilli in a novel manner, producing a layer of regularly spaced, spike-like granules.
在通过光学显微镜确认取自人类嗅觉区域的两块鼻内嗅黏膜活检组织后，对其进行了电子显微镜研究。值得注意的是，人类嗅觉细胞树突末端是扁平或圆顶状的，并非球状突起（嗅泡）。此外，纤毛位于嗅觉细胞的长轴上，与上皮表面垂直，并非如某些物种那样与上皮表面平行。支持细胞有多个长微绒毛，与嗅觉细胞有明确的接触点；它们似乎以一种新的方式将分泌物散布在微绒毛上，形成一层规则间隔的、尖状颗粒。
