Floor Of Mouth Anatomy Diagram

The major salivary glands three pairs in total are found in and around your mouth and throat.

Floor of mouth anatomy diagram.

The hard and soft palates form the roof of the mouth. The nasopharynx starts behind the nose and lies above the oropharynx located at the very back of your mouth. 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. Breathing acts as an air inlet in addition to the nasal cavity.

The tip is highly mobile anterior portion. 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. Anatomically you can distinguish between three tongue parts. The floor of mouth is an oral cavity subsite and is a common location of oral cavity squamous cell carcinoma.

It has three major functions. 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. Posteriorly a gap in the free border of the mylohyoid muscle allows free communication between the floor of the mouth and the submandibular space. Next comes the base which attaches the tongue to the floor of the mouth.

The major salivary glands are the parotid submandibular and sublingual glands the parotid glands are located in front and beneath the ear. Also learn about their function location in the body and conditions that affect the tonsils. Communication modifies the sound produced in the larynx to create a range of sounds. The oral cavity better known as the mouth is the start of the alimentary canal.

On the anterior end of the mouth the hard palate is formed by the inferior surface of the maxillae and palatine bones. The major aspects of tongue anatomy are being explained below. A duct called stensen s duct drains saliva from the parotid gland into the mouth at the area of the upper cheeks. Digestion receives food preparing it for digestion in the stomach and small intestine.

Posterior to it lies the body which has ventral and dorsal surfaces. The bottom of your mouth located under your tongue is called the floor. The floor of the mouth is formed by the tongue that covers most of it and mucous membranes that extend from the base of the tongue to the gums of the lower jawbone. This wall is hallmarked by three nasal conchae superior middle and inferior.

Muscles of the mouth none of the functions of the mouth could be performed without the help of the mouth muscles. The pharynx or throat is a tube about five inches long composed of three parts. The nasopharynx the oropharynx and the laryngopharynx.
