Chemical bonds do not store energy. Chemical bonds certainly contain potential energy, and the atoms want to move to a lower potential energy (become more stable). When methane, #CH_4#, forms, the valence electrons end up in more stable (lower energy) C-H bonds. These bonds are fairly strong, so methane is relatively inert.
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.
Sound causes the eardrum and its tiny attached bones in the middle portion of the ear to vibrate, and the vibrations are conducted to the nearby cochlea. The spiral-shaped cochlea is part of the inner ear; it transforms sound into nerve impulses that travel to the brain.The fluid-filled semicircular canals (labyrinth) attach to the cochlea and nerves in the inner ear. They send information on balance and head position to the brain. Otitis media (middle ear inflammation): Inflammation or infection of the middle ear (behind the eardrum). 2  Usually, this is caused by an infection. 3  Swimmerâs ear (Otitis externa): Inflammation or infection of the outer ear (pinna and ear canal).
