The development of the otic capsule and membranous labyrinth in the rats from the 18th day prenatal to the 5th day postnatal was studied.
The otic capsule was composed of mature cartilage and membranous labyrinth appears as a thickened pseudostratified layer. The epithelium of membranous labyrinth loses its stratification and become a simple columnar epithelium. Ossification of otic capsule was observed at the age of 2 days post natal.
The cristae ampullaris and macullae utriculi and succuli attain to mature form at the neonate and the greater part of the otic capsule is still consisted of cartilage in rats of 5 days of postnatal.
