 2Caution! 
- Do not use these PowerPoint images in lieu of 
going to lab! If you do not actually view the 
slides, models, dissections, and other lab 
materials first-hand in the lab your chances of 
doing well on the lab test are likely to be poor. 
  - The lab test will not be constructed using images 
of this PowerPoint presentation.  - This presentation does not necessarily review 
every aspect of the lab exercises on which you 
will be tested. Be aware of the objectives 
listed in the lab manual and any announcements 
made by your lab or lecture instructor as to test 
content.  - This should not be you only method of reviewing 
for the lab test. For example you should also 
reread all of the assigned exercises in your lab 
book.
