The olfactory lamellae of the channel catfish (Ictalurus punctatus) are composed of sensory and indifferent (non-sensory) epithelia organized into two distinct regions on both surfaces of each lamella. The smaller sensory region located adjacent to the midline raphe has fewer cilia per unit surface area than the indifferent epithelium and contains the olfactory neurons whose ciliated dendritic terminals occur at the epithelial surface. The indifferent epithelium, comprising the greater surface area of the olfactory lamella, is covered with a dense mat of non-sensory cilia. Fractured carbon dioxide critical point dried lamellar tissue revealed the underlying cellular structure. The lamellae are composed of two layers of epithelium enclosing a thin stromal layer. Olfactory receptors were observed in the fractured tissue only within the sensory epithelium.
沟鲶（斑点叉尾鮰）的嗅板由感觉上皮和无感觉（非感觉）上皮组成，在每个嗅板的两个表面上组织成两个不同的区域。位于中线缝附近的较小的感觉区域每单位表面积的纤毛比无感觉上皮少，并且包含其纤毛树突末端出现在上皮表面的嗅觉神经元。无感觉上皮占嗅板更大的表面积，覆盖着一层密集的非感觉纤毛。经二氧化碳临界点干燥的断裂嗅板组织揭示了其潜在的细胞结构。嗅板由两层上皮包围一层薄的基质层组成。仅在感觉上皮的断裂组织中观察到嗅觉受体。
