稳定蝇（Stomoxys calcitrans L.）的接触感受器位于跗骨和唇瓣上。在观察到的所有类型的接触化感受器中，远端神经纤维被包裹在从神经元附近延伸到丛集基部的角质层鞘中。一根远端纤维，假定为机械感觉纤维，终止于绒毛的基部，而其余远端纤维进入厚壁管腔并穿过乳头。所有的跗骨和唇瓣接触化学感受器检查显示，在作用部位的乳头上有一个孔，在这个孔下，远端神经纤维似乎未被修饰地终止。因此，神经纤维可能直接接触化学刺激。与两种跗接触化感受器相关的神经元数为5个。腹侧和内表面的唇瓣接触化学感受器分别由5个、4个或5个神经元支配。在每个跗骨和唇瓣接触化学感受器群和触觉毛的底部是一层围绕角质层鞘的膜，它可以作为角质层鞘的支撑或帮助检测敏感细胞的运动，或两者兼而有之。摘要作者：作者
The contact chemoreceptors of the stable fly, Stomoxys calcitrans L., are situated on the tarsi and labellum. In all the types of contact chemoreceptors observed, the distal nerve fibers were enclosed within a cuticular sheath which extends from the vicinity of the neurons to the setal base. On distal fiber, postulated as a mechanosensory fiber, terminates at the base of the seta, while the remaining distal fibers enter the thick-walled lumen and pass distad to the papilla. All tarsal and labellar contact chemoreceptors examined show a pore in the papilla at the site of action, beneath which the distal nerve fibers seem to terminate unmodified. It appears, therefore, that the nerve fibers may be exposed to direct contact with chemical stimuli. The number of neurons associated with 2 types of tarsal contact chemoreceptors of Stomoxys is 5. Labellar contact chemoreceptors in the ventral rows and on the inner surface are innervated by 5, and 4 or 5 neurons, respectively. At the base of every tarsal and labellar contact chemoreceptor seta and tactile hair is a membrane surrounding the cuticular sheath which may function as a support tor the cuticular sheath or aid in the detection of movements of the sensiilum, or both. || ABSTRACT AUTHORS: Authors
