The Supreme Courtâs conservative wing displayed skepticism about federal voting rights legislation when it struck down a key section of the landmark Voting Rights Act in 2013, so there are high stakes for the lawsuits in Ohio, North Carolina and elsewhere.
A retracted eardrum is a condition whereby the eardrum is sucked or pulled into the area behind it. This may arise due to low pressure in middle ear area. The eardrum is a thin flexible membrane that separates middle ear from outer ear. It is called the tympanic membrane. Infections may also cause a retracted eardrum.
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.
