Floor of mouth anatomy diagram.

Posterior to it lies the body which has ventral and dorsal surfaces. The major salivary glands three pairs in total are found in and around your mouth and throat. The floor of mouth is a u shaped space which extends and includes from the oral cavity mucosa superiorly and the mylohyoid muscle sling 2 3. Digestion receives food preparing it for digestion in the stomach and small intestine.

The tongue also helps to produce speech by altering or stopping the flow of air through the mouth to produce the sounds of many consonants. The major salivary glands are the parotid submandibular and sublingual glands the parotid glands are located in front and beneath the ear. Communication modifies the sound produced in the larynx to create a range of sounds. Posteriorly a gap in the free border of the mylohyoid muscle allows free communication between the floor of the mouth and the submandibular space.

The floor consists of the palatine process of the maxilla and the horizontal plate of the palatine bone. A duct called stensen s duct drains saliva from the parotid gland into the mouth at the area of the upper cheeks. Breathing acts as an air inlet in addition to the nasal cavity. Next comes the base which attaches the tongue to the floor of the mouth.

This wall is the nasal septum which is formed by the perpendicular plate of the ethmoid bone the vomer cartilage and the nasal crests of the maxillary and palatine bones. The bottom of your mouth located under your tongue is called the floor. The nasopharynx starts behind the nose and lies above the oropharynx located at the very back of your mouth. Anatomically you can distinguish between three tongue parts.

The nasopharynx the oropharynx and the laryngopharynx. The hard and soft palates form the roof of the mouth. Muscles of the mouth none of the functions of the mouth could be performed without the help of the mouth muscles. This wall is hallmarked by three nasal conchae superior middle and inferior.

In this article the surgical definition of the anatomy is used with the sublingual space defined as a part of the floor of the mouth figs 2 6. The major aspects of tongue anatomy are being explained below. It has three major functions. The tip is highly mobile anterior portion.

The pharynx or throat is a tube about five inches long composed of three parts. The floor of mouth is an oral cavity subsite and is a common location of oral cavity squamous cell carcinoma. On the anterior end of the mouth the hard palate is formed by the inferior surface of the maxillae and palatine bones.
