In the eye's case, however, the film screen is your retina. Your retina is in the very back of the eye. It holds millions of cells that are sensitive to light.

Dentures, also known as false teeth, are prosthetic devices constructed to replace missing teeth; they are supported by the surrounding soft and hard tissues of the oral cavity.
A partial denture is designed to fill in the gaps left by one or more missing teeth. It's a plastic, nylon or metal plate with a number of false teeth attached to it. It usually clips onto some of your natural teeth via metal clasps, which hold it securely in place in your mouth.
