Introduction:
              Oral cavity or mouth is that part  of body which is  present in cranial region. It is responsible for the digestion of food or it is the entrance for all type of nutrient that are requirement   for human body we ingest food with the help of our hand into the mouth where mouth cut the food into piece and transfer it toward the main functional area where it get further digested and absorbed in the body. Without entrance for food it is difficult to  set a goal for food to digest and absorption.
Anatomy
              It is started from lips it means lips are present Infront of the oral cavity and the behind of oral cavity oropharynx  a part of pharynx is present.
 When we talk about inferior and superior part of oral cavity on the superior area of oral cavity is hard and soft plate are present that make the roof of mouth. On its inferior area  tongue,

Mylohyoid muscle and  geniohyoid muscle are present.



That make the floor of oral cavity
layers of oral cavity
when we talk about the layers of oral cavity it has four layers.
1-      Serosa
It is the  most outer  layer of  oral cavity  which is make-up of skin that is responsible for providing protection to oral cavity through physically or chemically in physically protection it protect us from any type of sustainable trauma and also protect our mouth from foreign particle that are in the form of microorganism it traps them before attacking on our body. It defend us from microorganism through its defending system which is controlled by the immune system of human body.
2-      Muscularis
It is the second layer of oral cavity which is toward the inside of mouth that is made-up of muscle that provide a movement to mouth which help in digestion  and chewing of food with out these muscles it is totally difficult for us to chew food. The second thing is about muscles are it provide an attachment for the bones that are present around the mouth without there attachment it will be difficult for them to move and help in chewing food.
3-      Submucosa
It is the  third inner layer of oral cavity which contain blood vessels, lymphatic vessels and nerves that are responsible providing nutrient for the oral cavity, backflow of extra fluid and nutrient and last providing a control for that area respectively.
4-      Mucosa
It is the inner most layer of oral cavity which has further three sub-layers.
a-      Epithelium
It is the inner layer most layer  mucosa and oral cavity that contain Stratified squamous epithelium and  Keratinized or non-keratinized cells.
b-      Lamina propria
It is made-up of connective tissue which contain blood cells, immune cells and lymphatic cells.
c-       Submucosa
It contain salivary gland, blood vessels and nerve and also it is layer between mucosa and submucosa
 
What is stomatitis?
               It the inflammation of mucosal layer oral cavity which include tongue, soft plate, hard plate, cheeks, lips, gums and floor of the mouth. The inflamed area will be swollen, red and painful.

Diastolic blood pressure After contraction of ventricle during the relaxation time the remaining pressure of blood in blood vessel is called diastolic blood pressure. Introduction and stages of hypotension      If there is the presence of fluid in any system they have their own pressure such like human is a system and blood is a fluid it perform its function in its normal condition when it deviate from normal condition then it creates problem. When the blood pressure decreas...
