Hey mate...
The tympanic membrane is commonly known as the eardrum, and separates the ear canal from the middle ear. It is about 1cm in diameter and slightlyconcave (curving inward) on its outer surface. It vibrates freely in response to sound. The membrane is highly innervated, making it highly sensitive to pain.The ear canal is roughly 3cm long in adults and slightly S-shaped. It is supported by cartilage at its opening, and by bone for the rest of its length. Skin lines the canal, and contains glands that produce secretions that mix with dead skin cells to produce Cerumen. Cerumen, along with the fine hairs that guard the entrance to the ear canal, helps prevent airborne particles from reaching the inner portions of the ear canal, where they could accumulate or injure the eardrum and interfere with hearing. Cerumen usually dries up and falls out of the canal. However, it can sometimes become impact and disrupt hearing.

The membrane is highly innervated, making it highly sensitive to pain. A retracted eardrum is thought to occur when there is negative pressure in the middle ear.
