Journey through the ear

The video explains how ears function to enable hearing. It starts with the outer ear capturing sound waves, which are then transmitted by the eardrum to the ossicles in the middle ear. These bones pass the vibrations to the cochlea in the inner ear, where tiny hairs send signals to the auditory nerve. The brain interprets these signals, allowing us to hear. The video concludes by emphasizing that all ears, regardless of their shape or size, perform the same essential function.
