As a team, please complete the following surgical steps and answer the accompanying questions about the structures of the brain and their functions. When you are done, you will need to show Ms. Pember your finished product and submit this worksheet with your completed responses.

Checklist of Needed Items (these should be included in the bag you pick up or on the supply table):  Orange  2 raisins  1 Sour Brite Crawler  plastic knife  1 Sour Patch  1 Life Saver gummy  paper plate watermelon slice  1 Good n Plenty  8 colored toothpicks  1 Swedish fish  1 Sweet Tart small  plain toothpicks  1 candy orange slice round candy  Surgical Procedure 1) Carefully peel the skull from the brain. Do not puncture the white membrane, the meninges, that protect the brain.  2) You are now looking at the CEREBRAL CORTEX. Why is the cerebral cortex important?  ______ 3) Using the plain toothpicks, make two “eyes” with the raisins. Be sure to put them on the “end” of the brain (one of the sides with the stem “hole”). How do the eyes see in relation to the hemispheres of the brain?  ______ 4) With your knife, make a small incision, separating the cortex into two hemispheres, Remove a couple of segments of orange to expose the inner parts of the brain.  What are the specialized modes of thinking or functions of the RIGHT HEMISPHERE?  ______  What are the specialized modes of thinking or functions of the LEFT HEMISPHERE?  ______ ______5) Using your knife, carefully cut and remove the “CORPUS CALLOSUM” without cutting the brain in half. What is the function of the CORPUS CALLOSUM?  ______ 6) Using the Swedish Fish (Medulla) and Sour Patch watermelon slice (Pons) attach a MEDULLA and PONS to your brain (use plain toothpicks to attach).  What is the function of the MEDULLA?  ______ What is the function of the PONS?  ______ 7) Directly above and behind the brain stem, attach the candy orange slice to represent the CEREBELLUM. Use a plain toothpick to attach. What is the function of the CEREBELLUM?  ______ 8) Now divide the brain into LOBES. Mark the following using the toothpicks with colored tops. Remember to mark the lobes in both hemispheres.  FRONTAL LOBE—red—Function: ______ ______ PARIETAL LOBE—yellow—Function: ______ ______ TEMPORAL LOBE—green—Function: ______ ______ OCCIPITAL LOBE—blue—Function: ______ ______ 9) Where is the MOTOR CORTEX located? What does it regulate?  ______ 10) Where is the SOMATOSENSORY CORTEX located? What does it regulate?  ______ ______   11) Using the gummy Life Saver, place the THALAMUS in the brain (in the region you removed a few orange segments and the “corpus callosum” from earlier). What is the function of the THALAMUS?  ______ ______ 12) Using the Sweet Tart small round candy, place the HYPOTHALAMUS in the brain. What is the function of the HYPOTHALAMUS?  ______ ______ 13) Using the Good n Plenty, place the AMYGDALA in the brain. What is the function of the AMYGDALA?  ______ ______ 14) Using the Sour Brite Crawler, place the HIPPOCAMPUS inside the brain. What is the function of the HIPPOCAMPUS?  ______ ______ 15) What mid-brain system do the 3 structures above make up?  ______   Once you have completed the surgery, notify Ms. Pember so she can examine it and record a photo. Upon her approval, you can eat your brain and its parts, if desired.   PLEASE CLEAN UP YOUR MESS AND TURN IN THIS COMPLETED SHEET.              Orange (Brain) Surgery Model Support Station   Visual Depiction of End Result After Steps 1-4 and in the Process of Step 5:
