Adult Hearing Embryonic Origins
Many different embryonic components contribute to the sensory structures required for hearing. It is always considered/divided in terms of the 3 main divisions (external, middle and inner), each of which have their own separate components from different embryonic origins.
The complexity and time course of development leads to many associated abnormalities.
