Eye and Associated Structures

Eye and Associated Structures. 70% of all sensory receptors are in the eye Most of the eye is protected by a cushion of fat and the bony orbit Accessory structures include eyebrows, eyelids, conjunctiva, lacrimal apparatus, and extrinsic eye muscles. Eyebrows.

Unit 2: Chapter 5

Optical Systems make use of Mirrors and Lenses. Unit 2: Chapter 5. The Ray Model of Light. light is represented as a straight line or ray that shows the direction the light wave is travelling. Remember that light is made up of waves and can be described using wavelength and frequency.
