The document summarizes key aspects of the digestive system, including its main divisions and functions. The digestive system breaks down food mechanically and chemically. Mechanical digestion increases surface area through processes like chewing, while chemical digestion involves enzymes that break molecules into simpler compounds. Digestion occurs along the alimentary tube from the mouth to anus, aided by accessory organs like the liver, pancreas and gallbladder. The end products of digestion, like carbohydrates, proteins and fats, are absorbed and used by cells.
Physiology of taste(It is the recognition of liquid phase stimuli and also detection of chemical to the taste buds where nerve axonal fibre present but only from taste bud required for carrying information from tongue to the cortical level.
Mineralization (calcification) is the process of deposition of insoluble calcium salts in a tissue. It is one of the important steps in the formation of hard tissues of the body that is enamel, dentin, bone, and cementum. The synthetic cells, along with the help of the enzyme alkaline phosphatase, aid the mineralization process. The mineral content (inorganic portion) of all the hard tissues of the body is mainly in the form of Calcium hydroxyapatite crystals, Ca10(PO4)6(OH)2.
When calcium phosphate deposition is initiated, the crux is then to control spontaneous precipitation from tissue fluids supersaturated in calcium and phosphate ions and to limit it to well-defined sites. Formative cells achieve this by creating microenvironments that facilitate mineral ion handling and by secreting proteins that stabilize calcium and phosphate ions in body fluids and/or control their deposition onto a receptive extracellular matrix.
The synthetic cells achieve this property by secreting proteins that stabilize Calcium and Phosphate in the body fluids and control their deposition onto the extracellular matrix. These proteins are:
1. Salivary proteins
2. Enamel matrix protein
3. Dentin, cementum, and bone matrix proteins.

Paralysis of Swallowing Mechanism
Damage to the 5th, 9th, or 10th cerebral nerve can cause paralysis of significant portions of the swallowing mechanism.
Diseases, such as poliomyelitis or encephalitis, can prevent normal swallowing by damaging the swallowing center in the brain stem.
Finally, paralysis of the swallowing muscles, as occurs in muscle dystrophy or in failure of neuromuscular transmission in myasthenia gravis or botulism, can also prevent normal swallowing
These results into
complete abrogation of the swallowing act so that swallowing cannot occur
failure of the glottis to close so that food passes into the lungs instead of the esophagus
failure of the soft palate and uvula to close the posterior nares so that food refluxes into the nose during swallowing.

THIS PRESENTATION INCLUDES DETAILED INFORMATION ABOUT ACCESSORY ORGANS OF DIGESTIVE SYSTEM..i,e TEETH, TONGUE, SALIVARY GLANDS, PANCREAS, LIVER AND GALL BLADDER
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
