THROWBACK: Layers of the Eye

Mr. Davoren’s anatomy class learned about the multiple layers of the eye through the dissection of a cow’s eye!

Students used surgical scissors to cut away the fat and muscle surrounding the eye in order to see better (slight pun intended). This was the fleshy, white layer responsible for eye movement.

Students then cut away at the cornea, the clear surface that protects the eye. In doing so, an oozy fluid flowed! This fluid, called aqueous humor, gives the eye its shape and is made of water and protein.

Next, students cut the eye in half, through the sclera. This allows for the retina and lens to be easily seen.

Despite obvious physical differences between a cow eye and a human eye, this lab allowed students to learn about the multiple layers of the eye in addition to their functions. In turn, students gained knowledge about the human eyes thought this hands on experiment.
