Question
Chapter 17, Problem 17.5.2AYLO
Summary Introduction
To explain:
The formation of the structures of the outer and the middle ear from the first two pharyngeal arches and the first pharyngeal pouch.
Introduction:
The ear is related to the sensory function of hearing. It is divided into three regions, that is, outer, middle and inner ear. The first two regions perform only the conduction of the sound waves, and the latter one produces sound.
