There are no glands in the mucosa of the oesophagus, epithelial surface of which is keratinized. The stomach consists of the following four compartments, forestomach, main stomach, connecting channel and pyloric stomach. The forestomach is a dilatant part of the oesophagus. The cardiac glands are found at narrow zone along the border line between the forestomach and the main stomach. The histologieal and morphological characteristic of the compartments have been interpreted in relation to feeding habits and function of Neophocoena phocaenoides. |
