Human Ear and Range of Hearing

The video explains the structure and function of the human ear, highlighting its three main parts: the outer ear, middle ear, and inner ear. The outer ear includes the pinna and auditory canal, while the middle ear contains the eardrum and three bones. The inner ear features the cochlea. Sound waves are collected by the pinna, transmitted through the auditory canal, and cause the eardrum to vibrate. These vibrations are amplified by the middle ear bones and transformed into electrical signals by the cochlea, which are then sent to the brain via the auditory nerve for interpretation.
