对14只鹿鼠（Peromyscus maniculatus）的鼻腔进行了组织学检查，以确定嗅上皮表面积的变化及其与鼻腔体积、非嗅上皮表面积和体型的相关性。被面积为129.8 mm 2的非嗅觉上皮覆盖的手形肌;上皮表面由从吻侧角化复层鳞状到尾侧纤毛假复层柱状的类型渐变组成。该上皮的大部分是无纤毛的，没有杯状细胞。位于非嗅上皮背尾侧的是嗅上皮表面，面积为166.8 mm 2 in。在包含两个亚种、两种性别和不同年龄的小鼠样本中，总的、非嗅和嗅上皮表面的面积高度可变。非嗅觉和嗅觉上皮的表面积测量值与体长、体重和鼻腔体积显著相关。P鼻腔上皮细胞面积与体积之比相对恒定。有毛的据推测，在一个物种中，空气中的分子与上皮面积的比例可能是稳定的。
The nasal cavities of 14 deer mice,Peromyscus maniculatus, were examined histologically to determine the variability in surface area of the olfactory epithelium and its correlation with nasal cavity volume, area of non‐olfactory epithelial surface, and body size.Forty‐four per cent of the nasal cavity surface ofP. maniculatusis covered by a non‐olfactory epithelium with an area of 129.8 mm2; the epithelial surface consists of gradations in type from keratinized stratified squamous rostrally to ciliated pseudostratified columnar caudally. An extensive portion of this epithelium is non‐ciliated and devoid of goblet cells. Situated dorsocaudal to the non‐olfactory epithelium is the olfactory epithelial surface measuring 166.8 mm2in area.The areas of total, non‐olfactory and olfactory epithelial surfaces are highly variable in a sample of mice containing two subspecies, both sexes and various ages. Surface area measurements of non‐olfactory and olfactory epithelia are correlated significantly with body length, body weight and volume of the nasal cavity. A relatively constant epithelial area to volume ratio is present in the nasal cavity ofP. maniculatus. It is surmised that a stable ratio of molecules in the air to epithelial area may occur within a species.
