BUCCAL CAVITY

What is Buccal Cavity?

The mouth is also called as the buccal cavity or the oral cavity. In the human digestive system mouth is the upper end or the beginning of the alimentary canal, which leads to the pharynx and to the esophagus. In humans, both the mouth or the buccal cavity and the nasal cavity are separated by the palate.

The buccal cavity mainly comprises the primary organ of the digestive system including the teeth, tongue and salivary glands.

The mouth is an opening through which the food is taken inside the body. It is bounded by lips and its inner parts comprise of the cheeks, tongue, upper jaw and lower jaw.

The upper jaw is fixed, which forms the roof of the mouth cavity and consists of palate, teeth, and gums surrounding the teeth. The lower jaw is movable and forms the floor of the mouth cavity, which consists of the tongue along with the teeth and gums surrounding them. The mouth plays an important role in speech, helps in breathing in certain cases, when the nose is blocked and during strenuous exercise. It is also the most important part of the human body, which permits us to enjoy the food we eat and also to communicate with the rest of the world.

The mouth or the oral cavity comprises of two parts:

The oral cavity proper — It mainly comprises of the tongue.
The oral vestibule – It is the slit-like space between the teeth and the buccal cavity and between the lips and cheeks.

TOPICS TAUGHT:

-- Saliva is a mixture of water, mucus, antibacterial substances, and digestive enzymes. One of the most recognizable digestive enzymes in human saliva is amylase. This enzyme is able to break down the starch in our food to simpler and more easily digestible sugars like glucose and maltose. Whenever we chew, we are activating salivary glands in preparation for the breakdown of our meal.
Salivary Glands Function
Briefly, saliva itself serves many uses. As the only secretion of our salivary glands, it is helpful in creating the food bolus, or the finely packed ball of food that we roll inside our mouths. This shape facilitates its safe passage through our alimentary canal. Saliva has lubricating properties that are protective, as well. Saliva protects the inside of our mouths, our teeth, and our throats as we begin to swallow the bolus. It also cleanses the mouth after a meal and dissolves food into chemicals that we perceive as taste.
