Comparative Histomorphological Studies on Oesophagus of Catfish and Grass Carp
Figure 2
Photomicrograph showed the morphological characteristic features of the anterior part of oesophagus of catfish (a–e), posterior part of oesophagus of catFish (f–i), and oesophagus of grass carp (j–n). Highly folded mucosa (m); short mucosal folds (mf); wide channels of lumen (L); columnar epithelium (ep); goblet cells (gc); taste buds (Tb); club cells (cc). Notice the negative PAS reaction of club cells (cc), muscularis mucosa (mm), lamina propria (Lp), tunica submucosa (S), tunica muscularis (M), and adventitia (ad). The square indicated one mucosal fold. (a), (e), (i), (f), (j), and (n) ; (b), (c), (g), (k), and (l) ; (h) ; (d) and (m) .
