Lagena
Definition:
(n.) The terminal part of the cochlea in birds and most reptiles; an appendage of the sacculus, corresponding to the cochlea, in fishes and amphibians.
Example Sentences:
(1) The recess is an evagination of the lagena, and is invested externally by dense periotic connective tissue, except over a thin area of one wall abutting against a periotic diverticulum communicating with the periotic sac.
(2) Hair cell polarization patterns were investigated on the sensory macule of the sacculus and lagena of the lake whitefish.
(3) The results provide evidence that the neurones with periodic spontaneous discharge innervate the lagena and that this sense organ has no auditory significance in birds.
(4) The response dynamics of afferents in the utricle and lagena correspond with the macular locations of their peripheral arborizations.
(5) In Ancistrus afferents of sacculus and lagena terminate in an area which is distinct based on its cytoarchitecture.
(6) The otic relationships of the recess and papilla to the proximal part of the lagena and saccule are described, and new terminology is suggested for the periotic relationships of the basilar recess to a diverticulum of an intracapsular periotic sac.
(7) However, a far greater number of type A hair cells were found in high frequency sensitive sensory organs (sacculus, amphibian and basilar papillae) than low frequency sensitive vestibular sensory structures (canal cristae, utriculus and lagena).
