  Instructions:

      Today’s lab includes a sheep brain dissection. Try to save the first six cranial nerves (or at least one of each pair). I will go around to help you. When finished, you should place the brain back into the jar and put your name, your partner’s name, and your class time or section on the jar. The sheep brains will be stored in the cadaver room. You cannot take them home because they are preserved and could be toxic. This is school policy!
