Find a skull. Locate and identify the openings where the following structures pass into (or out of) the skull: Cranial nerve II: • Cranial nerve VIII: Auditory canal: • Spinal cord: Where is the gray matter located in the brain, relative to the white matter? Is this the same or different than the gray versus white matter of the spinal cord?

Now find the median brain model and identify the same structures on the model. SHEEP BRAIN DISSECTION • First examine the sheep brain from the outside, without dissecting anything. What do you see? • • Gently cut away the dura mater, so you can see the surface of the brain. Identify the cerebral lobes. • Identify the structures of the brain stem. • Identify as many Cranial Nerves as you can, based on the location where they are connected to the brain (use textbook Figure 14-5 as a reference). Make a sagittal cut to separate the right and left halves of the brain. Now identify the midline structures including ventricles. • • Make a frontal cut through the frontal lobes. Identify white and gray matter. Identify ventricles. ADDITIONAL QUESTIONS Find a skull.
