REVIEW #21 - PART 1

     Part 1 of this review includes 20 views; the first 9 are assorted drawings or photographs of gross brains and the remaining 11 are brain sections. A number of structures are identified on each view and you are asked to identify each one. Questions alternate with answers as you scroll down. To keep yourself honest, narrow the height of the viewable window so you can't see the "answer" while you are working on the "question".
