Abstract

Introduction: The ear, originates from the ectoderm, exhibits a complex structure that differs from species to species in terms of development.

Objectives: This study was conducted to describe the prenatal and postnatal development process of the organ of Corti in the iner ear using light microscopy.

Methods: In this study, Wistar Albino rats were used. The rats were divided into two groups as prenatal and postnatal groups. Prenatal groups consisting of embryos on day 17, 19, 21 and postnatal groups consisting of pups on days 1, 5, 10 and 15. The rats were sacrificed to investigate the cochleas by light microscopy.

Results: The lumen of the cochlear tunnel was lined with pseudostratified columnar epithelia throughout the prenatal period. The cochlear tunnel was not divided into scala media, scala tympani and scala vestibuli in the embryonic sections. Organ of corti hasn’t taken its final form until postnatal day 15.

Conclusion: In rats, formation of organ of Corti is completed in postnatal 15 day. Pups of rats are not able to hear in the embronic and early postnatal life.
