-
The aperture, formed by the iris, that allows light to enter the eye.
-
The collection of ganglion cell axons that extend from the retina to the optic chiasm.
-
The region of the retina devoid of receptor cells because ganglion cell axons and blood vessels exit the eyeball there.
-
The central region of the retina, which has a dense concentration of cones. Each central cone has its own ganglion cell.
-
The area where theses (along with the neural axons) enter and leave the retina forms the blind spot.
-
The receptive surface inside the eye that contains the rods and cones.
-
The circular structure of the eye that provides an opening to form the pupil.
-
A structure in the eye that helps form an image on the retina. Its shape is controlled by the ciliary muscles inside the eye.
-
This structure has a fixed curvature. It bends light rays and is primarily responsible for forming the image on the retina.
-
These control the shape of the lens.
