What is the floors?
The word "floor" accepted various meanings in English, most of which had to do with food or drink. For example, cleaning someone's floor is a common proverb for cleaning the taste of the mouth; Similarly, something that is inedible is not suitable for eating. However, the anatomical purpose of the floor has little to do with taste. Palated is basically a roof of the mouth, divided into soft and hard parts. It separates the oral cavity of the mouth from the nasal cavity and cavities and creates a barrier between the inner functioning of the nose and the mouth.
In humans and most vertebrates are two parts of the floors. The hard floor is the largest part and sits directly above the tongue, between the upper row of the teeth. It is mainly made of bone. It is the basic part of the oral cavity and its shape often dictates how well the upper and lower teeth fit together.
On the other hand, the soft floor is fleshy and cumper. It is also called velum, is located behind the hard floor, almost to the neck, and its main function is to act as a physical barrier between the oral and nasal cavities. While the hard part of the departureIt lines the nose from the mouth of the bone, the neck and nasal cavities are still connected. The soft part limits and closes this connection when swallowing food or drink. Without velum, foods intended for the stomach could divert into the nasal cavity.
Speech sounds are also strongly affected by velum, as velum helps control the amount of air in the mouth and vocal tract. People form sounds and words in the vocal tract, which is a collective name for the larynx, pharynx, oral cavity and nasal cavity. Behind the nasal speech is often the blame of velum, which is under form or poorly created. Velum abnormalities were also accused of various speeches, such as stuttering, although the medical causes of most obstacles are not definitely known.both hard and soft portions are formed in fruits during the first trimester of pregnancy. In a small percentage of people estimated in 2010 per seven hundred, the floor is not fully interested. This leaves a gap or cleft in the middle of the mouth, which normally extends over the lips and nose. Unsured heels are commonly oznailed as clefts or split lips and affect people of all races in all countries.
Many scientific studies have combined splits with a lack of folic acid during pregnancy. However, adequate levels of folic acid do not guarantee the right floor formation and the condition is not a condition that can be prevented. Clefts can be repaired by surgery. Surgery can restore the physiological role of hard and soft palates, and usually also repairs any facial abnormalities caused by cleft.
