Studies on Tongue of Reptilian Species Psammophis sibilans, Tarentola annularis and Crocodylus niloticus

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...
