Membrane-associated structures were studied in the cells of the basilar papilla, the hearing organ of a lizard, Calotes versicolor, by means of freeze-fracture. Zonulae occludents of an intermediate to tight type were found to join the apical membranes of sensory and supporting cells. Gap junctions were frequently observed between neighboring supporting cells. The size and shape of the gap junctions varied considerably. Their distribution was as follows: small junctions were seen apically, large ones basally. This finding suggests the existence of electrical coupling among the supporting cells. Only afferent synapses have been described in this organ. Aggregates of particles were found in the pre- as well as the post-synaptic membranes, similar to those described at synapses in the central nervous system.
利用冷冻蚀刻技术对变色树蜥听觉器官基底乳头细胞中的膜相关结构进行了研究。发现中间型至紧密型的紧密连接连接着感觉细胞和支持细胞的顶端膜。在相邻的支持细胞之间经常观察到缝隙连接。缝隙连接的大小和形状差异很大。它们的分布如下：顶端可见小连接，基部可见大连接。这一发现表明支持细胞之间存在电耦合。该器官中仅描述了传入突触。在突触前膜和突触后膜中都发现了颗粒聚集体，类似于中枢神经系统突触中所描述的那些。
