is the first portion the digestive system. Horseshoe-shaped open back.
Inside the mouth there are two main parts: the oral vestibule (space between the lips and cheeks) and the dental arches. The second portion is the oral cavity, its anterior limit is the dental arches and posterior limit is the oropharyngeal isthmus which lies behind the pharynx. The rear wall of the oral cavity is the palate, which forms the upper limit. The soft palate is mobile and highlights the uvula, the hub of two extensions (the pillars of the veil). Palates are located between the palatine tonsils.
Occupying most of the buccal space is the language. It provides the lingual papillae. The tongue is a muscular organ covered with mucosa in addition to taste function, involved in the formation of the bolus and its passage into the pharynx. In the rear of the tongue papillae are arranged in a V calciformes is the V lingual.
In the oral cavity and implanted into dental alveoli are located teeth. There are 32 teeth (16 in each jaw): 4 incisors, 2 canines, 4 premolars and 6 molars.
Inside the mouth secretions drain into the salivary glands are:
sublingual gland:
secretion has several passages that drain directly to the floor of the mouth.
gland submaxillary:
The exhaust duct known as Wharton, drains through the oral mucosa, on both sides of the frenulum in the floor of the mouth.
parotid gland:
The exhaust duct is the tube that empties Stenon oral cavity near the second upper molar.
