Dissection

As part of the IB Biology Option A Neurobiology and Behavior unit, the 12th grade standard level biologists dissected pig eyes (obtained from a humane source).

 

The mammalian eye is a complex structure that evolved over millions of generations. The optic nerve was very visible during the dissection, as was the lens, iris, and retina. We do not often perform dissections in the lab due to the existence of sophistocated simulations that are more readily available. However, dissection activities provide a hands-on inquiry opportunity for students to explore what are often complex organs and organ systems.

After learning about the structure and function of each part of the eye, the biologists will move on to study the even more complex (!) way in which photoreceptors in the retina respond to light stimuli.
