mastication

Examples of mastication in the following topics:

• Ingestion

  • Once in the mouth, the teeth, saliva, and tongue play important roles in mastication (preparing the food into bolus).
  • Mastication, or chewing, is an extremely important part of the digestive process, especially for fruits and vegetables, as these have indigestible cellulose coats which must be physically broken down.
  • Ingested food must be broken down into small pieces by mastication, or chewing.

• Chewing Muscles

  • Mastication, or chewing, involves the adduction and lateral motions of the jaw bone.
  • Mastication, or the act of chewing, involves adduction and lateral motion of the jaw bone.
  • Masseter - The most powerful muscle of mastication.
  • It covers the other muscles of mastication.

• Vertebrate Digestive Systems

  • Birds have developed a digestive system adapted to eating un-masticated (un-chewed) food.
  • The teeth play an important role in masticating (chewing) or physically breaking down food into smaller particles.
  • They do not have teeth, so their digestive system must be able to process un-masticated food .

• Fibrous Joints

  • It also pumps blood and lymph from the periodontal membrane into the dental veins and lymph channels and stimulates sensory nerve terminals in the membrane to send signals to the brain centers that control the muscles of mastication.

• Digestive System: Mouth and Stomach

  • The food is broken into smaller particles by mastication, the chewing action of the teeth.
  • Food is masticated by teeth and moistened by saliva secreted from the (b) salivary glands.

• Temporomandibular Joint Syndrome (TMJ)

  • Temporomandibular joint disorder (TMD or TMJ) syndrome is an umbrella term covering acute or chronic pain primarily in the muscles of mastication, and/or inflammation of the temporomandibular joint, which connects the mandible to the skull.

• Trigeminal (V) Nerve

  • The motor component of the mandibular division (V3) of the trigeminal nerve controls the movement of eight muscles, including the four muscles of mastication: the masseter, the temporal, and the medial and lateral pterygoids.

• Processes and Functions of the Digestive System

  • The organs in the alimentary canal include the mouth (the site of mastication), the esophagus, the stomach, the small and large intestines, the rectum, and the anus.
  • Saliva moistens the food, while the teeth masticate the food and make it easier to swallow.

• Digestion in the Mouth, Pharynx, and Esophagus

  • When food enters the mouth, digestion begins with the action of mastication, a form of mechanical digestion, and with the contact of saliva.

• Organs of the Digestive System

  • The chewing process here is also known as mastication.
