The type of teeth used for tearing in man is labelled

Answer Details

The diagram shows the arrangement of teeth in the human jaw, with four distinct types labelled I through IV. Label I indicates the incisors, which are flat, chisel-shaped teeth at the front used for cutting and biting. Label II indicates the canines, the pointed, conical teeth located just behind the incisors. Label III indicates the premolars, which have two cusps and are used for crushing. Label IV indicates the molars, the broad, multi-cusped teeth at the back used for grinding.

The teeth used for tearing in humans are the canines. Canines have a single, sharp, pointed cusp that is well-suited for gripping and tearing food, particularly meat. They are the longest teeth in the human dentition and are homologous to the prominent fangs seen in carnivorous mammals. In the diagram, the canines are labelled II.
