Abstract: Objective The macula lagena in birds is located at the apical end of the cochlea and contains many tiny otoliths. 摘要：目的 鸟类瓶状囊器官位于耳蜗的顶端，含有耳石并有神经支配，但其功能尚不清楚。
To clarify this issue, we carried out a study to determine whether or not otoliths in the lagena of homing pigeons are richer in magnetic elements than those in the saccule and the utricle. 为澄清这个争议，本研究分析成年信鸽瓶状囊耳石磁性元素的含量是否比内耳球囊和椭圆囊耳石更丰富。
vestibule A chamber leading into other cavities or passages, e.g. of the inner ear, of the utriculus, sacculus, lagena. 前廊一个腔室进入其他的洞或通道，例如内耳，椭圆囊，球囊，听壶。
(2)After transferred to spermatheca,the sperms stored in the utriculus in the form of sperm mass.No sperm was found in lagena; (2)精子转移至受精囊后只分布于主囊，成团聚集，副囊中没有精子；
lagena The lower, posterior and outer chamber of the inner ear projecting from the sacculus, probably responsible for hearing. 听壶内耳的下面的后部与外部腔室，从球囊突出，可能跟听觉有关。
