Fig. 5 in Morphological analysis of the oviduct, oviducal gland and isthmus of the blue shark Prionace glauca (Linnaeus, 1758) (Elasmobranchii: Carcharhiniformes)

Fig. 5. Micrographs of the Baffle zone of Prionace glauca. (A): tubules that open between epithelial projections (pr) in the central lumen (L) of the GO; Terminal zone (T). SEM. (B): projections (pr) in greater increase, similar to the lamellae. SEM. (C): each epithelial projection (pr) is surrounded by short epithelial folds (ef). HE. (D): tubules are formed by cells ciliated columnar (c) and glandular (gc); connective tissue (ct); tubule lumen (tl). HE. Scale bars: 300 µm (A); 100 µm (B and C); 10 µm (D).
