The convex superior surfase of the tongue is called: the back (dorsum) #the fundus the apex the margin !2 The mucosa extending from the floor of the mouth to the inferior surface of the tip of the tongue forms on the midline: the frenulum of the tongue #the frenilum of the inferior lip the frenulum of the superior lip the lingual septum ! The muscles of the tongue are divided into: proper (intrinsic) and skeletal (extrinsic) #smooth and striated smooth and proper smooth and skeletal (extrinsic) !1 The palate forms the upper wall of the oral cavity and is divided into: the hard palate and the soft palate #the bony palate and the hard palate the muscular palate and the soft palate the superior palate and the inferior palate ! Each tooth consists of: the crown, the neck, the root #the body, the neck, the root the crown, the isthmus, the root the head, the neck, the root !1 The root of tooth sits in the dental alveolus and terminates in: the apex #the fornix the fundus the cupola ! The hard material of the tooth consists of: dentine, enamel, cement #dentine, pulp, connective tissue enamel, cement, elastic tissue dentine, cement, pulp ! The root canal of the tooth opens at: the apex of the root #the base of the root the crown of the tooth the neck of the tooth ! How many are the deciduous teeth? 20 #32 26 30 !
