2019年10月4日 · Mastication is the mechanical grinding of food into smaller pieces by teeth; it is essentially a technical word for “chewing”. Mastication breaks down food so that it can go through the esophagus to the stomach.

Chewing or mastication is the process by which food is crushed and ground by the teeth. It is the first step in the process of digestion, allowing a greater surface area for digestive enzymes to break down the foods. During the mastication process, the food is positioned by the cheek and tongue between the teeth for grinding.

2023年11月2日 · Origins, insertions, innervation and functions of the muscles of mastication. The muscles of mastication are a group of muscles that consist of the temporalis, masseter, medial pterygoid and lateral pterygoid muscles.

2024年10月1日 · The muscles of mastication are a group of muscles associated with movements of the jaw. There are four muscles - the masseter, temporalis, medial pterygoid and lateral pterygoid.

2020年1月26日 · Mastication involves the interplay of teeth, bones, muscles, and soft tissues. Soft tissues include the tongue, lips, and cheeks. The soft tissues keep food in the mouth and move it around so that it mixes with saliva and is presented to the teeth.

2023年6月5日 · The primary muscles of mastication (chewing food) are the temporalis, medial pterygoid, lateral pterygoid, and masseter muscles. The four main muscles of mastication attach to the rami of the mandible and function to move the jaw (mandible).

Mastication is one of the primary behaviors expressed by the organ systems of the oro-facial region. It is the process where food is split up into smaller pieces, thus making them available for further enzymatic handling in the gastrointestinal tract.

chewing, 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. In cats and dogs, food is reduced only to a size that permits easy swallowing.

Mastication significantly reduces food size, allowing for easier swallowing and further digestion in the stomach and intestines. The teeth play a vital role in mastication, with molars designed for grinding food while incisors are used for cutting.

2024年7月5日 · The process—known scientifically as mastication—varies widely across different groups such as mammals, reptiles, birds, and insects. Understanding these differences can offer insights into the evolutionary adaptations that allow each group to thrive on their respective diets.
