Functional Anatomical, Histological and Ultrastructural Studies of three Chameleon Species: Chamaeleo Chamaeleon, Chamaeleo Africanus, and Chamaeleon Vulgaris 77
Fouda,Yosra A; Sabry,Dalia A; Abou-Zaid,Dalia F.
Three chamaeleon species including Chameleon Chamaeleo chamaeleon, Chameleon Chamaeleo africanus, and Chamaeleon vulgaris were collected and their tongue were dissected and examined morphologically and investigated using light and scanning electron microscopy. Both species showed similar histological manifestation of lingual papillae and tubular glands with dense mucous secretion especially in Chamaeleon vulgaris. There is no keratinization of lingual surfaces. Ultrastructurally, filliform represent the only pattern of lingual pappillae and take either cylindrical, conical and leaflet structure.Although the examined chalmaeleon species collected from different habitat, it shows almost similarities in their histological and ultrastructural structures.

Studies on Tongue of Reptilian Species Psammophis sibilans, Tarentola annularis and Crocodylus niloticus 77
El-Sayyad,Hassan I.H; Sabry,Dalia A; Khalifa,Soad A; Abou-El-Naga,Amora M; Foda,Yosra A.
Three different reptilian species Psammophis sibilans (Order Ophidia), Tarentola annularis (Order Squamata and Crocodylus niloticus (Order Crocodylia) are used in the present study. Their tongue is removed and examined morphologically. Their lingual mucosa examined under scanning electron microscopy (SEM) as well as processed for histological investigation. Gross morphological studies revealed variations of tongue gross structure being elongated with bifurcated end in P. sibilans or triangular flattened structure with broad base and conical free border in T. annularis or rough triangular fill almost the floor cavity in C. niloticus. At SEM, the lingual mucosa showed fine striated grooves radially arranged in oblique extension with missing of lingual...
