Ground RulesGround Rules

This room is all we have. We need to find a way to make it work, so we can do what we're here to do.

1. Absolutely no food or drink consumption in the classroom.

2. No open liquid containers in the classroom. They must be kept outside.

3. No conversing during lecture.

4. If you can't hear the instructor or another student during lecture or question and answer, please politely say so.

5. If you're sitting in the back and having difficulty hearing, move to the front of the classroom next time.

6. Dial down your drama. If you're anxious about this class, find something constructive to do about it.

Blunt Trauma-most common cause of A deviated septum Any impact can potentially detach perpendicular plate of ethmoid bone from nasal septum wall, allowing septum to deviate from one side to other.
