In human anatomy, the eardrum, or tympanic membrane, is a thin, cone-shaped membrane that separates the external ear from the middle ear in humans and other tetrapods. Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea. Hence, it ultimately converts and amplifies vibration in air to vibration in fluid. The malleus bone bridges the gap between the eardrum and the other ossicles.
There are three main parts of the ear- the outer ear, the middle ear and the inner ear. The outer ear is just the pinna (the part that sticks out of the head) and the ear canal, which ends at the eardrum. The ear canal is where earwax accumulates. The middle ear is the space behind the eardrum. This space is drained and ventilated by a pathway called the Eustachian tube, which runs from the ear to the back of the nose. The inner ear is deep inside the skull, and is where the nerves and other structures controlling hearing and balance are located.
