Title: Anat & Phys 8/30/06 Objectives: Class Topics Chapter 1 Test 11/23/2018 Title: Anat & Phys 8/30/06 Objectives: To assess knowledge of preliminary information and begin learning about histology Class Topics Chapter 1 Test Histology Epithelial tissue Keep on beginning and failing. Each time you fail, start all over again, and you will grow stronger until you have accomplished a purpose - not the one you began with perhaps, but one you’ll be glad to remember Anne Sullivan Friday, November 23, 2018 6:54 AM
