HISTOLOGICAL STUDY OF PITUITARY GLAND IN TELEOST

Abstract

In teleost fish, the pituitary gland is essential for controllingin regulating growth, metabolism, reproduction, and osmoregulation through its dynamic endocrine functions.Adenohypophysis and neurohypophysis make up the pituitary gland, which is further divided into the pars and rostral pars distalis, pars intermedia and pars nervosa,which house specialized hormone-secreting cells. These regions exhibit significant species-specific structural and functional adaptations influenced by environmental factors, developmental stages, and reproductive cycles. These studies provide a deeper understanding of teleost endocrine regulation and its evolutionary adaptations.
