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. The retina takes the light the eye receives and changes it into nerve signals so the brain can understand what the eye is seeing. A Muscle Makes It Work
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.
Unlike a bridge, a partial denture is a removable prosthetic solution. A partial denture can be, for example, a plate made of acrylic plastic or metal to which artificial teeth are fixed. When the partial denture is installed into the mouth, the gaps caused by missing teeth are covered by the teeth in the denture.
