Final answer:
Musical sound travels from the outer ear through the auditory canal to the tympanic membrane, through the ossicles of the middle ear, and reaches the cochlea in the inner ear, where it is converted into neural signals sent to the brain.
Step-by-step explanation:
The region through which musical sound passes as it comes from the atmosphere and into our ear and then makes its way to the temporal lobe of the brain is known as the auditory pathway. This pathway starts with the outer ear, particularly the auricle and the auditory canal, where sound waves enter and travel to the tympanic membrane, or eardrum. The tympanic membrane vibrates in response to the sound waves. These vibrations then move through the ossicles of the middle ear, consisting of the malleus (hammer), incus (anvil), and stapes (stirrup), and enter the inner ear via the oval window. Within the inner ear, the vibrations reach the cochlea, which is filled with fluid and lined with tiny hair cells. These hair cells convert the vibrations into neural signals which are then transmitted to the brain through the auditory nerve. The temporal lobe of the brain processes these signals, allowing us to hear and understand sounds.
