蝙蝠翅膀膜是由专门的皮肤，覆盖着小的感觉毛，这可能是机械感觉，并已被建议帮助蝙蝠在飞行过程中感觉气流。迄今为止，在世界各地1,400多种蝙蝠中，只有少数几种研究了这些感觉毛发。人们对整个蝙蝠发育过程中感觉毛网络的多样性知之甚少。在这项研究中，我们使用高分辨率的显微照片保存蝙蝠翅膀12个家庭的17个物种的特点感觉毛沿着翼和物种之间的分布。我们确定跨物种的感觉毛分布的一般模式，包括感觉毛的膜内翅肌，在翅膜的结缔组织网络，前肢的骨骼的明显关系。我们还描述了这些感觉结构在某些物种的独特集群。我们还量化了感兴趣的propatagium，plagiopatagium，和dacloppagatia的几个区域的感觉毛密度，发现感觉毛密度高于近端比远端。在比较的背景下，这种检查的感觉毛网络的解剖组织提供了一个框架，现有的研究感觉毛的功能，并强调进一步研究的途径。
Bat wing membranes are composed of specialized skin that is covered with small sensory hairs which are likely mechanosensory and have been suggested to help bats sense airflow during flight. These sensory hairs have to date been studied in only a few of the more than 1,400 bat species around the world. Little is known about the diversity of the sensory hair network across the bat phylogeny. In this study, we use high‐resolution photomicrographs of preserved bat wings from 17 species in 12 families to characterize the distribution of sensory hairs along the wing and among species. We identify general patterns of sensory hair distribution across species, including the apparent relationships of sensory hairs to intramembranous wing muscles, the network of connective tissues in the wing membrane, and the bones of the forelimb. We also describe distinctive clustering of these sensory structures in some species. We also quantified sensory hair density in several regions of interest in the propatagium, plagiopatagium, and dactylopagatia, finding that sensory hair density was higher proximally than distally. This examination of the anatomical organization of the sensory hair network in a comparative context provides a framework for existing research on sensory hair function and highlights avenues for further research.
