Histochemical Localization of Alkaline and Acid Phosphatases in the Lateral Line Canal Organs of a Freshwater Teleost, Saccobranchus fossilis

In the present study, the significance of the presence of alkaline and acid phosphatases in the epithelial cells lining the pores and the lateral line canals and also the border of the sensory and supporting cells of the neuromast organs are linked with the permeability processes. The significance of the presence or absence of the phosphatases in various sites of the cells of the neuromast organs are discussed from the functional point of view of the elements composing the sense organs.
