The incus, also known as the anvil, is one of the three small bones in the middle ear called the ossicles. It is located between the malleus (hammer) and the stapes (stirrup). The incus plays a vital role in the transmission of sound vibrations. When the eardrum vibrates in response to sound waves, the malleus transfers these vibrations to the incus, which then passes them on to the stapes. This chain of transmission helps amplify and transmit sound from the outer ear to the inner ear, enabling the process of hearing.

The tympanic duct, also known as the scala tympani, is a fluid-filled chamber located in the cochlea of the inner ear. It is one of the three chambers of the cochlea, alongside the vestibular duct and the cochlear duct. The tympanic duct extends from the apex of the cochlea to the round window, which is covered by a membrane. The primary function of the tympanic duct is to transmit sound vibrations that have traveled through the cochlear duct. These vibrations are transmitted to the round window, causing it to move and allowing for the dissipation of the fluid's pressure. The tympanic duct plays a vital role in the process of hearing by helping to amplify and transmit sound signals for further processing by the auditory system.

The Eustachian tube, also known as the auditory tube, is a small passageway that connects the middle ear to the back of the throat. It plays a crucial role in equalizing the air pressure between the middle ear and the environment. The Eustachian tube is responsible for regulating pressure changes in the middle ear, allowing the ear to function properly. It opens during activities like swallowing or yawning, allowing air to enter or leave the middle ear and equalize the pressure. This action helps to protect the eardrum from damage and ensures optimal hearing. Additionally, the Eustachian tube serves as a drainage pathway for fluid that may accumulate in the middle ear, helping to maintain a healthy and balanced ear environment.

The round window is a small, membrane-covered opening located in the inner ear, specifically in the cochlea. It plays a crucial role in the transmission of sound waves and the maintenance of proper fluid pressure within the cochlea. When sound vibrations enter the cochlea, they cause the fluid inside to move. The round window acts as a pressure relief valve, allowing the fluid to move and preventing damage to the delicate structures of the inner ear. This dynamic function of the round window is essential for our ability to perceive and interpret sound.
