Organs specialized for the perception of stimuli such as sight, hearing, balance, taste, and smell, integrating multiple structural and functional components.

Optic Disc

The point of exit for ganglion cell axons leaving the eye, where the optic nerve begins, and notably lacks photoreceptor cells, creating a "blind spot."

Blind Spot

The point in the visual field that lacks light-detecting photoreceptor cells, located where the optic nerve exits the eye, creating a spot where no image is perceived.
