Oral cavity
Oral Cavity (Mouth) Refers to the mouth. It includes the lips, the lining inside the cheeks and lips, the front two thirds of the tongue, the upper and lower gums, the floor of the mouth under the tongue, the bony roof of the mouth
Lips
Anatomically, the philtrum and its pillars are a part of the upper lip. The surface of the lip is comprised of four zones: hairy skin, vermilion border, vermilion and oral mucosa.
Uvula
During swallowing, the soft palate and the uvula move together to close off the nasopharynx, and prevent food from entering the nasal cavity
Vestibule
a chamber or channel communicating with or opening into another, in particular.
Lingual frenulum
a small fold of mucous membrane extending from the floor of the mouth to the midline of the underside of the tongue.
Oropharynx
the part of the pharynx that lies between the soft palate and the hyoid bone.
Larygopharnx
The laryngopharynx is where both food and air pass. It can be found between the hyoid bone and the larynx and esophagus, which helps guide food and air where to go. It is a part of the pharynx.
Esophagus
the part of the alimentary canal that connects the throat to the stomach; the gullet. In humans and other vertebrates it is a muscular tube lined with mucous membrane.
Stomach
the internal organ in which the major part of the digestion of food occurs, being (in humans and many mammals) a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine.
Cardioesophageal sphincter
The lower esophageal sphincter, or gastroesophageal sphincter, surrounds the lower part of the esophagus at the junction between the esophagus and the stomach. It is also called the cardiac sphincter or cardioesophageal sphincter, named from the adjacent part of the stomach, the cardia.
Pyloric sphincter
The pyloric sphincter is a band of smooth muscle at the junction between the pylorus of the stomach and the duodenum of the small intestine.
Rugae
Rugae is a term used in anatomy that refers to a series of ridges produced by folding of the wall of an organ. Most commonly the term is applied to the internal surface of the stomach
Greater curvature
the boundary of the stomach that forms a long usually convex curve on the left from the opening for the esophagus to the opening into the duodenum — compare lesser curvature.
Lessercurbature
the lesser curvature of the stomach, extending between the cardiac and pyloric orifices, forms the right or medial border of the stomach.
