LETS INVESTIGATE FURTHER.... Two major sections of the tooth Crown & Root Crown: the part of the tooth you are able to see Root: The part of the tooth that is embeded in the gums (similar to how you can t see a plants roots) Cusp- pointed or rounded elevation on crown of tooth Enamel- very hard tissue that covers the crown Dentin- ivory like substance that forms the body of the tooth

CONTINUED.... Pulp- center of tooth-contains nerves, blood and lymph vessels Cemetrum: bone like tissue that covers the root ( think cement because its hard like bone)

FLASH CARDS Using a blank sheet of paper you are going to create flash cards with the terms we have learned today in class. When writing out the flash cards, try to use different colors or types of handwriting to help associate the terms with their definition. Go through your set of flash cards a few times then work with someone to quiz them on these terms.
