FIGURE 7 in Phylogenetic assessment of ultrastructural and histological characters of teeth in the Anostomoidea, Hemiodontidae and Parodontidae (Teleostei: Ostariophysi: Characiformes)

FIGURE 7. Caenotropus labyrinthicus (Kner, 1858) MCP 22515, 54.28 mm SL – A: Premaxilla, cross section (10x). Small arrow points the connective tissue surrounding each tooth. B: Replacement row teeth (20x). Small arrows points to the apical region of the replacement teeth. C: Replacement tooth (40x); D: Contact region of the functional teeth (20x). E: Premaxilla, cross section, functional teeth, showing that most of the tooth is embedded in epithelial tissue. AM=ameloblasts; DF=functional teeth; DN=dentin; DS=replacement teeth; ES=enamel; LP=periodontal ligament; OD=odontoblasts; PA= dental papilla; PO=pulp; PMX=premaxilla; TA=adipose tissue; TC=connective tissue; TE=epithelial tissue; TO=bone tissue.
