Olfactory epithelium in Tiliqua scinoides is of a loosely packed pseudostratified type. It receives secretion from the supporting cells and the underlying glands of Bowman. Its surface bears microvilli and cilia from sensory cells and microvilli from supporting cells. The vomeronasal epithelium is also pseudostratified but higher and more closely packed. Its surface carries microville from sensory and supporting cells but lacks cilia. Vascular connective tissue penetrates it almost to the epithelial surface but is always outlined by basal cell processes and a basal lamina. There are no secretory cells in or under the sensory epithelium but some cells in the epithelium of the mushroom body contain secretion granules. Sensory cells of both epithelia are bipolar neurons. The perikarya of the vomeronasal cells are more neuronal in character. Axonic processes are similar in both, dendrites are distinctive. Olfactory dendrites end in rounded rods bearing microvilli and cilia of an unusual type. Microville with filamentous cores occur on vomeronasal dendrites. There are no cilia, but 2-6 centrioles appear below the cell surface. Basal cells are structurally similar in both epithelia, but axonic processes of olfactory cells are surrounded by supporting cell processes, while vomeronasal axonic processes are surrounded by basal cells before they leave the epithelium. The presence of cilia and microville on the surface of the sensory cells is discussed in relation to the physical conditions surrounding them.
蓝舌石龙子的嗅上皮是一种排列疏松的假复层类型。它接受支持细胞和鲍曼氏腺的分泌。其表面有感觉细胞的微绒毛和纤毛以及支持细胞的微绒毛。犁鼻上皮也是假复层，但更高且排列更紧密。其表面有感觉细胞和支持细胞的微绒毛，但没有纤毛。血管结缔组织几乎穿透到上皮表面，但总是由基底细胞突起和基膜勾勒出轮廓。感觉上皮内或其下方没有分泌细胞，但蘑菇体上皮中的一些细胞含有分泌颗粒。两种上皮的感觉细胞都是双极神经元。犁鼻细胞的胞体更具神经元特征。两种上皮的轴突过程相似，树突则不同。嗅树突末端呈圆形杆状，带有微绒毛和一种特殊类型的纤毛。犁鼻树突上有带丝状核心的微绒毛。没有纤毛，但在细胞表面下方出现2 - 6个中心粒。两种上皮的基底细胞在结构上相似，但嗅细胞的轴突过程被支持细胞突起包围，而犁鼻轴突过程在离开上皮之前被基底细胞包围。讨论了感觉细胞表面纤毛和微绒毛的存在与它们周围物理条件的关系。
