Otoconia biogenesis, phylogeny, composition and functional attributes

摘要: This work consolidates data about these interesting organic crystals of vertebrate inner ears. It addresses 5 aspects ear otoliths not completely understood to date: 1) embryological that explains the formation crystals, 2) significance and inorganic phase otolith changing patterns otoconia along evolutionary tree, 3) contribution for detecting linear acceleration, 4) effect altered gravity aminoglycosides have on development adult shape a from primitive forms (lamprey) high birds mammals is discussed, 5) functional attributes otolithic organs morphological modifications by physical chemical insults are presented with an extensive discussion most relevant literature published available us.
