Histological and histochemical studies on the olfactory rosette of Mugil parsia (Hamilton)

The structure and functions of the olfactory organs in Mugil parsia (Ham.) has been described. Histologically each lamella consists of supporting, olfactory receptor, basal, labyrinth and mast cells. The distribution and localization of acid and neutral mucins in the various cells of olfactory epithelium in M. parsia has been studied histochemically. Variations in the localization of glycogen in the different cells of the olfactory epithelium have been correlated with the functional significance of the region concerned in the fish studied.
