Digestive system

Parotid salivary gland

Parotid salivary gland (glangula parotidea) is a paired, serous type of secretion. The gland has an irregular shape, outside it is covered with a thin capsule. Weight of the gland 20-30 g.

Salivary glands (glandulae oris) are divided into large salivary glands (parotid, submandibular, sublingual) and small salivary glands (glands of the oral cavity, pharynx, upper respiratory tract). The first - paired, the second - plural.

Language

Language (lingua) participates in the mechanical processing of food, in the act of swallowing, in taste perception, in the articulation of speech. The tongue is located in the oral cavity. It is a flattened, flattened muscular organ. The tongue tapers in front, forming the apex of the tongue (apex linguae). The apex of the back passes into the broad and thick body of the tongue (corpus linguae), behind which lies the root of the tongue (radix linguae).

Teeth

Teeth (dentes) are important anatomical formations located in the dental alveoli of the jaws. Depending on the features of the structure, position and function, several groups of teeth are distinguished: incisors, canines, small molars, or premolars, and large molar molars.

The cavity of the mouth (cavitas oris)

The cavity of the mouth (cavitas oris) is located in the lower part of the face, is the beginning of the digestive system. The oral cavity is limited from below by the maxillofacial muscles that make up the muscular base of the lower wall of the oral cavity - the diaphragm of the mouth (diaphragma oris). The upper wall of the oral cavity is formed by a hard and soft keb, from the sides - cheeks, in front - lips. Behind the oral cavity through a wide opening - fauces - communicates with the pharynx. The oral cavity is divided into a smaller front section - the vestibule of the mouth and the actual oral cavity.

Abdomen: Topographic Anatomy

The abdomen is part of the body, located between the chest at the top and the pelvis below. The upper border of the abdomen passes from the base of the xiphoid process along the costal arches to the XII thoracic vertebra.
