Complete this description of the eye. The eye has many structures built into it which enable us to see. It is composed of three layers. The outermost layer, composed of a fibrous material, is called the________ . This layer stretches around the front of the eye and becomes transparent. At this point it is called the___________ . The middle layer, the_________ , is made of a darkly pigmented tissue. The third or inner layer is responsible for the reception of the light rays and the translation of that stimulus into an impulse for the optic nerve, which takes it to the brain for interpretation of the image. This light-sensitive layer is called the___________ . Light enters the eye via a circular opening called the____________ . This eye part can be opened or constricted by a special colored part of the middle eye layer called the , which acts much as the shutter on a camera works. The light is focused on to the light-sensitive inner layer by the_____________ , which can be changed in shape by the ciliary muscle.
