Lagena is #12, and is labeled at upper left and lower left.
In human anatomy of the ear, the extremities of the ductus cochlearis are closed; the upper is termed the lagena and is attached to the cupula at the upper part of the helicotrema; the lower is lodged in the recessus cochlearis of the vestibule.
In fish and amphibians
The lagena is part of the vestibular system in fish and amphibians. It contains the otoliths asterisci. In fish, the lagena is implicated in hearing and the registration of vertical linear acceleration, in amphibians in the latter only.
