ACOUSTIC MEATUS Meaning and
Definition
-
The acoustic meatus, also known as the external auditory canal, is a passageway located within the human ear that connects the outer ear with the middle ear. It functions as a pathway for sound waves to enter the ear, facilitating the process of hearing.
The acoustic meatus is an approximately 3 centimeter long tube that begins at the visible external opening of the ear known as the ear canal. It then extends inward, gradually tapering in diameter until it reaches the tympanic membrane, also called the eardrum. The meatus is lined with skin that contains hair follicles, sebaceous glands, and ceruminous glands, which produce ear wax (cerumen). This wax helps to keep the ear canal lubricated and protected from foreign particles, preventing them from reaching the delicate structures of the ear.
The acoustic meatus plays a crucial role in the transmission of sound. When sound waves enter the ear, they travel through the ear canal and strike the eardrum, causing it to vibrate. These vibrations are then transmitted to the tiny bones of the middle ear, known as the ossicles, which amplify the sound and pass it on to the inner ear. From there, the sound signals are converted into electrical signals that are sent to the brain, where they are interpreted as sound.
In summary, the acoustic meatus is a vital component of the auditory system, serving as the gateway for sound waves to enter the ear and initiate the process of hearing.

Etymology of ACOUSTIC MEATUS
The word "acoustic" originates from the Latin word "acusticus", which means "pertaining to hearing". It is derived from the Greek word "akoustikos", meaning "of or for hearing".
The word "meatus" also comes from Latin and means "passage" or "channel". It is derived from the word "meare", which means "to go, pass, or flow".
Therefore, when combined, "acoustic meatus" refers to the "hearing passage" or the exterior opening of the ear canal, which leads to the middle ear.
