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.
The floor of the oral cavity consists of several structures.
The floor of the mouth is a horizontally aligned u shaped space situated in the part of the oral cavity that lies beneath the tongue.
The floor is formed by the mylohyoid muscles and is occupied mainly by the tongue.
Geniohyoid muscles pull the larynx forward during swallowing.
This region is divided into right and left halves by the lingual frenulum and contains the ostia of the submandibular and sublingual salivary glands.
It is bounded by a roof a floor and lateral walls.
Several submandibular and sublingual salivary glands secrete viscous and mucoid fluid to lubricate and keep the oral cavity moist.
The mylohyoid muscles constitute the floor of the oral cavity proper.
It provides structural support to the floor of the mouth and pulls the larynx forward during swallowing.
A mucous membrane the oral mucosa lines the sides and under surface of the tongue to the gums lining the inner aspect of the jaw mandible.
A mucous membrane known as the oral mucosa is composed of stratified squamous epithelium and forms the inner lining of the mouth.
These include the hard palate floor of the mouth buccal mucosa including the upper and lower gingivobuccal sulci retromolar trigone and anterior two thirds or oral portion of the tongue and lips figs.
The mylohyoid genioglossus and geniohyoid muscles comprise the muscular floor of the oral cavity.
For purposes of surgical planning the floor of the mouth is defined as the space between the mucosal surface and the mylohyoid muscle sling and comprising both structures 1.
The oral cavity proper is also surrounded by mucus membrane continuing from the vestibular walls 10.
The oral cavity is situated anteriorly on the face under the nasal cavities.
The oral cavity encompasses several relatively discrete regions.
