The basilar papilla of the chicken was studied by transmission and scanning electron microscopy. It is composed of two distinct types of hair cells, a tall hair cell (THC) and a short hair cell (SHC). Gradual transitions exist between these two forms. The THC occurs mainly in the anterior part of the neuroepithelium and is situated on the superior fibro-cartilagenous plate, while the SHC dominates in the posterior part and is found on the free basilar membrane. The THC is a tall columnar cell with an elongated hexagonal apical surface. One kinocilium and 150 to 220 stereocilia protrude from the center of its surface. The THC makes synaptic contact with several large afferent nerve terminals and with small bouton-shaped efferent terminals. The SHC is short and thick, having a much wider surface area than the THC. From the inferior part of the surface of the SHC 90 to 120 stereocilia protrude, whereas the kinocilium is lacking. The nucleus is located near the base of the cell. Small afferent nerve terminals and extremely large efferent nerve endings synapse with the SHC.
利用透射电子显微镜和扫描电子显微镜对鸡的基底乳头进行了研究。它由两种不同类型的毛细胞组成，即高毛细胞（THC）和短毛细胞（SHC）。这两种形式之间存在逐渐过渡。THC主要出现在神经上皮的前部，位于上纤维软骨板上，而SHC在后部占主导地位，位于游离基底膜上。THC是一个高柱状细胞，顶端表面呈拉长的六边形。一根动纤毛和150至220根静纤毛从其表面中心伸出。THC与几个大的传入神经末梢和小的纽扣状传出末梢形成突触联系。SHC短而粗，表面积比THC大得多。90至120根静纤毛从SHC表面下部伸出，而动纤毛则不存在。细胞核位于细胞基部附近。小的传入神经末梢和极大的传出神经末梢与SHC形成突触。
