The starling cochlea was studied with TEM at four locations along the basilar papilla to investigate gradients in morphological features over the papilla's length and width. Hair cell shape changes continuously from neural to abneural and from basal to apical. Unlike the situation in mammals, there are no distinct populations of hair cells; the previously described types (tall hair cells and short hair cells) are merely extremes in a continuum. Contacts between THC are a normal feature. Except at the base of the papilla, SHC have very large cuticular plates, suggesting a micromechanical function for these cells. In contrast to the THC, the SHC normally completely lack afferent innervation; this indicates that their function is restricted to within the basilar papilla itself. © 1992 Wiley-Liss, Inc.
利用透射电子显微镜（TEM），在沿基底乳头的四个位置对欧椋鸟的耳蜗进行了研究，以探究在乳头长度和宽度上形态特征的梯度变化。毛细胞的形状从神经侧到非神经侧、从基部到顶部不断变化。与哺乳动物的情况不同，不存在明显不同的毛细胞群体；先前描述的类型（高毛细胞和短毛细胞）仅仅是连续统一体中的极端情况。高毛细胞之间的接触是正常特征。除了在乳头基部外，短毛细胞具有非常大的角质板，这表明这些细胞具有微机械功能。与高毛细胞相反，短毛细胞通常完全缺乏传入神经支配；这表明它们的功能仅限于基底乳头本身。© 1992威利 - 利斯公司。
