abstract: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.
The macula lagena is anotherotolithicorgan in the inner ear of non-mammals, and the lagena of more advaced birds develops better than that of lower animals.
