1 Chemical reactions are an integral part of technology, of culture, and indeed of life itself. Burning fuels, smelting iron, making glass and pottery, brewing beer, and making wine and cheese are among many examples of activities incorporating chemical reactions that have been known and used for thousands of years.
Not to be confused with the secondary tympanic membrane of the round window. 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.ts 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.

DEAR READER: Your eardrum is a thin membrane involved in hearing. It separates your ear canal (the part that is open to the outside) from your middle ear. The outer, middle, and inner ear. The outer ear consists of the parts you can see: the fleshy outer part (called the auricle), the ear canal, and the eardrum. The middle ear is an air-filled cavity containing the ossicles, three small bones (malleus, incus, and stapes) that transmit vibrations to the inner ear.
