The Oral Cavity || PART - 1

The anatomy of the oral cavity is quite complex, as it consists of several parts. The functions and a description of each of these parts will be explored in this BLOG.
You all see how each part of the oral cavity  has developed and how each function.







THE PALATE 
The palate is often described as the "roof of the mouth." The palate itself is a long structure that is covered by several soft tissue components. The palate is divided into two major sections -- the hard palate and the soft palate.

THE HARD PALATE
The hard palate is located in the anterior portion of the mouth. A thin epithelial tissue, known as the oral mucosa, covers it. The oral mucosa is made of a dense, highly proliferating tissue that allows it to regenerate quickly.
There is an area in the anterior section of the hard palate that which is known as the palatine rugae. It is in the area where the mucosa folds into irregular ridges just behind the maxillary anterior teeth that the palatine rugae can be located. At the end of the palate is a common area that is utilized for both respiration and digestion. This area aids in both the passage of air for respiration and the swallowing of nourishment for digestion. This section is typically the beginning of the throat and is termed the pharynx.

THE SOFT PALATE
The soft palate is located posterior to the hard palate. It is made of soft tissue, including muscle and oral mucosa. The function of the soft palate is to aid in the process of swallowing. The soft palate actually moves up and back to cover the nasopharynx when we swallowing mechanism is initiated. This motion prevents food items from entering the airway, thus preventing choking or aspirating. The soft palate consists of two main parts -- the uvula and the tonsils. The uvula is located at the edge of the soft palate, at the center of the entrance of the throat. It consists mainly of lymphatic tissue and assists the body in fighting systemic infections. The tonsils are located near the soft palate on both sides of the pharoroynx. The oropharynx extends from the soft palate to the epigllotis, which keeps food from entering the larynx. The oropharynx is the part of the throat that you can see when you look into the mouth. The tonsils are also composed of lymphatic tissue and assist in fighting infections in the body.
