A handy of free and printable mouth diagrams has been collected in the best resolution! When you want to be a dentist, nurse, or whatsoever it s, you need to learn the anatomy of the mouth. The mouth is lined by stratified squamous epithelium, from which oral smears may be taken for chromosomal studies. The temperature in the mouth is about 37 degrees. The oral cavity consists of two portions, the vestibule and the oral cavity proper. The vestibule is the cleft between the lips and cheeks externally and the gums and teeth internally. The parotid duct opens opposite the upper second molar. When the teeth are in contact, the vestibule and oral cavity proper communicate only by a gap between the last molars and the ramus of the mandible. Provided below is the detail anatomy of the human mouth.
As you can see in the mouth diagram above, at the entrance to the mouth are the lips, or labia. Their outer covering is skin, which transitions to a mucous membrane in the mouth proper. Lips are very vascular with a thin layer of keratin; hence, the reason they are “red.” Moving farther into the mouth, the opening between the oral cavity and throat (oropharynx) is called the fauces. The main open area of the mouth, or oral cavity proper, runs from the gums and teeth to the fauces. Below are the diagrams that will show you what are there above and beneath the tongue.
The throat, or pharynx, is a funnel-shaped tube located in the posterior of the mouth. The pharynx connects the nasal cavity and mouth to the esophagus and larynx in the neck. The region of the throat behind the mouth is known as the oropharynx and forms the posterior wall of the mouth. Food in the mouth is swallowed into the oropharynx and passed on to the esophagus and the rest of the gastrointestinal tract. Air inhaled through the mouth or nose also passes through the pharynx on its way to the larynx, and then passes through the pharynx on its way out of the body during exhalation. The tongue is attached to the mandible, the styloid processes of the temporal bones, and the hyoid bone. Many small salivary glands are housed within the mucous membranes of the mouth and tongue. Each of the major salivary glands secretes a unique formulation of saliva according to its cellular makeup.
From the diagrams above, it is pretty clear explained and illustrated the structure of the mouth anatomy. Get the diagram pictures for free and find other anatomy diagrams in the other posts in this site for free!
