In Lytocestus indicus putative neurosecretory cells (pNSC) are recognized on the basis of phloxinophilic and fuchsinophilic nature of their cytoplasm. PNSC in L. indicus are dimensionally small. Morphologically, there are four types of pNSC: a-, uni-, bi-, and multipolar cells. They are found both in the cortical and medullary parenchyma of the neck and strobilar regions; in the latter the pNSC occur in close vicinity with the longitudinal muscles and components of the reproductive system.
