Mastication: The human teeth is designed for chewing and the anterior incisors are for cutting, posterior teeth or molars are grinding. The jaw muscles (masseter, medial pterygoid pterygoid, lateral pterygoid, temporalis) close the teeth with a force of 55 pounds for the incisors and 200 pounds for the molars. There is a chewing reflex which controls most of chewing. Chewing aids digestion by increasing the total surface area of food exposed to digestive secretions.
