How to write a lab report for eye dissection

Cow Eye Dissection Introduction: How do we see? The eye processes the light through photoreceptors located in the eye that send signals to the brain and tells us what we are seeing. There are two types of photoreceptors, rods and cones.

These photoreceptors are sensitive to the light. Rods are the most sensitive to light and therefore provide gray vision at night.

Cones are mainly active in bright light and enable you to see color. There are million rods compared to the 3 million cones located in your retina. The photoreceptors help you adjust to night and day. For example, if you walk inside from the sun, you can not initially see anything. This is due to the activity of the cones and the lack of activity of the rods.

The rods become activated and adapted to the dim light, resulting in gray images formed in the dark. The same thing happens when you leave a dark movie theatre during the day.

The rods are mainly activated and the cones have to adjust to sunlight when you leave the theatre. By dissecting the eye of a cow, which is similar to the eyes of all mammals including humans, you will gain an understanding of the structure and function of the parts of the eye.
