Directions: Locate each of the listed structures on your bullfrog specimen. As you locate the structure,
put a checkmark next to the name of the structure. At the end of each section, you will see a signal to
STOP. When you reach this point, please raise your hand and Ms. Fisher will come over to your table.
At that time, you will need to quickly and efficiently show Fisher the structures on the specimen. Fisher
will stamp that section, indicating completion. Once the stamp is provided, please continue to the next
section. Please refer to the frog dissection handouts to help you identify the locations of the various
structures as well as their functions. By the end of the dissection, you should be familiar with not only
the location, but also the function of each of the structures you identify.
