What is mastication process?
Mastication (chewing), in which food is crushed and mixed with saliva to form a bolus for swallowing, is a complex mechanism involving opening and closing of the jaw, secretion of saliva, and mixing of food with the tongue.
Why is it called masticate?
Masticate comes from the Late Latin masticāre, meaning “to chew,” from the Greek mastikhan, “to grind the teeth.” The English word mastic derives from the same Greek word and refers to a type of tree and the resin from it that’s used to make rubber and chewing gum.
What is mastication short answer?
Chewing or mastication is the process by which food is crushed and ground by teeth. It is the first step of digestion, and it increases the surface area of foods to allow a more efficient break down by enzymes.
Where does mastication occur in the digestive system?
Mastication is the first step of the digestive process. After food has been masticated in the mouth, it travels to the stomach, where it is macerated into semi-digested, partially liquid material called chyme. Nutrients from chyme are absorbed in the intestines, and the leftover material, fecal matter, is excreted.
What is mastication anatomy?
Mastication is defined as the act of chewing food (Fig. 8-2). It represents the initial stage of digestion. During mastication, the food bolus is broken down into small particles for ease of swallowing.

What is mastication and what muscles are involved?
Introduction and Overview The muscles of mastication are a group of muscles responsible for the chewing movement of the mandible at the temporomandibular (TMJ) joint, they enhance the process of eating, they assist in grinding food, and also function to approximate the teeth.
What is the process of chewing called?
chewing, also called mastication, up-and-down and side-to-side movements of the lower jaw that assist in reducing particles of solid food, making them more easily swallowed; teeth usually act as the grinding and biting surface.
What is deglutition in biology?
Deglutition is the transport of a bolus of food or liquid from the mouth to the stomach. 12. Normal deglutition requires precisely timed contraction and relaxation of numerous muscles of the oral and pharyngeal regions (Table 54-1).
