| posteriorly on thee dorsal surface of the base of the tongue is an irregualr mass of tissue called the | lingual tonsil |
| the side or lateral surface of the tongue has vertical ridges called the | foliate lingual papillae |
| the underside of the tongue is called the | ventral surface of the tongue |
| True or False the ventral surface of the tongue has small visible blood vessels, the deep lingual veins, which pass far from the surface. | Flase the ventral surface of the tongue has LARGE visible blood vessels, the deep lingual veins, which pass CLOSE to the surface. |
| lateral to each deep lingual vein are fringelike projections called | plica fimbriata (plural, plicase fimbriatae) |
| midline fold of tissue between the ventral surface of the tongue and the floor of the mouth is the | lingual frenum |
| joining the V-shaped configuration extedning from the lingual frenum to the base of the tongue, on each side of the floor of the mouth is the | lingual fold |
| small papila at the anterior end of each sublingual fold contains openings of the submandibular duct and sublingual duct are | sublingual caruncle |
| the muscular tube that serves both the repiratory and digestive systems is the | pharynx |
| The division of the pharynx that is superior to the level of the soft palate and is continuous with the nasal cavity is the | nasopharynx |
| the division of the pharynx between the doft palate and the opening of the larynx and is the oral part of the pharynx is the | oropharynx |
| True or False part of all three divisions of the pharynx are visible on an intraoral examination | False only part of the nasopharynx and the oropharynx are visivle on an intraoral examination |

| A normal variation noted usually on the facial surface of the alveolar process of the maxillary arch, and are localized developmental growths of normal bone with a possible hereditary etiology are | exostoses |
