Copy the following:
Epi-
Hypo-
Derm-
Serous membrane-
Mucous membrane-
Synovial membrane-
Use your background knowledge and book to define these vocabulary words.

2. Unit 3 Test
No test corrections, so why should we reflect on what we missed?
These questions will likely be on the final and on the CAST test!
Unlike prior years the CAST now counts for 20% of your second semester grade.
