Final answer:
The canine teeth, located immediately after the lateral incisors, are pointed teeth used for tearing food. Premolars follow the canines, with a flatter shape for mashing food, and molars are the furthest back for crushing food.
Step-by-step explanation:
The question refers to the arrangement and function of teeth in humans. Immediately posterolateral to the lateral incisors are the canine teeth, which are pointed and are used for puncturing and tearing food. Positioned next to the four sharp front teeth, known as incisors, the canine teeth have a pointed tip or cusp that make them ideal for this purpose. Behind the canines are the premolars or bicuspids, which have a flatter shape with two rounded cusps for mashing food. Lastly, come the molars with multiple cusps for crushing food so it's ready for swallowing.
