Digestion and Dental Anatomy

It is a cell of newel crest origin that is part of the outer surface of the dental pulp and whose biological function is dentinogenesis, which is the formation of dentin.

The hardest part of a tooth is the enamel. It forms the outer layer. Enamel is made up of a mineral called hydroxylapatile which is the name for crystallivl calcium phosphate.

The incisor tooth is meant for biting and cutting incisors are the front teeth present in most retardant mammals. They are located is the premaxilla above and on the moudible below. Humans have a total of eight.

Fluorine as it is the most reactive of all elements and no chemical substance is capable of freeing fluorine from any of its compounds. 

Among mammals, a herbivore hasflatter teeth than carnivore 

A digestive enzyme, salivary amylase, in the saliva begins digestion of nucleic acids. 

A person produce about 1500 ml of saliva day. It is a watery substance located in the mouths of animals. Secreted by the salivary glands the enzymes found in salina are essential is beginning the process of objection of dietary starches and fails.

Pepsin acts within the stomach so its optimum pH is around 2, an acidic pH. When the enzyme enters the duodenum, it comes in contact with a higher pH and its enzyme activity comes to and end. 

Pepsin digests the proteins in stomach. 

Ptyalin (Salivary amylase).It is found in saliva and breaks starch into maltose and dextrin. 

Trypsin enzyme in mammals is formed from the trypsinogen by the action of enterokinase. 

Zymogens require a biochemical change to become an actual enzyme.

Lipidis the most concentrated energy source. 

Pepsinogen is secreted by chief cells. The chief cells have an extensive network of landler rough endoplasmic reticulum organised around the nucleus. They also contain many large secretory vesicles filled with digestive enzymes in the pilar cytoplasm.

In the presence of lactase, lactose breaks down into molecules ofglucose and galactose, which can then be metabolised to produce energy. 

Rennin, protease found in rennet. It is produced by newborn ruminant animals in the lining of the fourth stomach to curdle the milk they ingest, allowing a longer residence in the bowels and better absorption. It is widely used in the production of cheese. 

Diastema is associated with absence of certain tooth. It is a space or gap between two teeth. Many species of mommals have distemata as a normal feature. It is a adjustable dental condition.

A bolus is a mass of food that (with animals that can chew) has been chewed at the point of swallowing. Under normal circumstances, the bolus then travels down the oesophagus to the stomach for digestion. 

If you chew on a piece of bread long enough, it will begin to taste sweet because amylase is breaking down starches to disaccharides. 

As, Glycoproteins are simply proteins with a sugar attached to them.
