Editing Incisor (section)

==Function==
In [[cat]]s, the incisors are small; biting off meat is done with the [[canine tooth|canines]] and the [[carnassial]]s. In [[elephant]]s, the upper incisors are modified into curved [[tusk]]s (unlike with [[narwhal]]s, where it is a canine that develops into a straight and twisted tusk).<ref>{{cite journal|last=Nweeia|first=Martin|last2=Eichmiller|first2=Frederick C.|last3=Hauschka|first3=Peter V.|last4=Tyler|first4=Ethan|last5=Mead|first5=James G.|last6=Potter|first6=Charles W.|last7=Angnatsiak|first7=David P.|last8=Richard|first8=Pierre R.|last9=Orr|first9=Jack R.|last10=Black|first10=Sandie R.|title=Vestigial Tooth Anatomy and Tusk Nomenclature for Monodon Monoceros|journal=The Anatomical Record |date=30 March 2012 |volume=295|issue=6|pages=1006–1016|doi=10.1002/ar.22449|pmid=22467529|display-authors=8|doi-access=}}</ref> The incisors of [[rodent]]s grow throughout life and are worn by gnawing. In humans, the incisors serve to cut off pieces of food, as well as in the grip of other food items.
