GENERAL HISTOLOGY

Detailed explanation-1: -Mechanical digestion in the oral cavity consists of grinding of food into smaller pieces by the teeth, a process called mastication.

Detailed explanation-2: -The role of your teeth Teeth break down food for swallowing and further digestion. The incisors, located in the middle front of the lower and upper jaws, cut and gnaw pieces of food. The molars, in the back of the mouth, grind and chew.

Detailed explanation-3: -A digestive enzyme in saliva called amylase (pronounced: AH-meh-lace) starts to break down some of the carbohydrates (starches and sugars) in the food even before it leaves the mouth. Swallowing, done by muscle movements in the tongue and mouth, moves the food into the throat, or pharynx (pronounced: FAIR-inks).

Detailed explanation-4: -Ingestion – the taking in of food Food is taken into the mouth where it is physically broken down by the teeth into smaller pieces. The presence of food in the mouth triggers a nervous reflex that causes the salivary glands to deliver a watery fluid called saliva to the mouth.

Detailed explanation-5: -Mastication is a sensory-motor activity aimed at the preparation of food for swallowing. It is a complex process involving activities of the facial, the elevator and suprahyoidal muscles, and the tongue.
