Title: Anat & Phys 9/6/06 Objectives: Class Topics 11/24/2018 Title: Anat & Phys 9/6/06 Objectives: To assess knowledge of preliminary information and begin learning about histology Class Topics Histology Review Epithelial & Connective tissue Notes – complete connective tissue Histology Lab “Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination are omnipotent.” Calvin Coolidge Saturday, November 24, 2018 12:24 AM
