Online Published on 18 December, 2023. Abstract Pituitary gland of Pangasius pangasius was examined through light microscope and transmission electron microscope (TEM). It is slightlyprotruding and forwardly directed. Hypophysis showed adenohypophysis and neurohypophysis. The adenohypophysis consists of three parts named viz. Rostral Pars Distalis (RPD), Proximal Pars Distalis (PPD) and Pars Intermedia (PI). Adenohypophysis exhibits lactotropic cells, adrenocorticotropic cells and somatotropic cells in RPD. In PPD, gonadotropic cells, somatotropic cells and thyrotropic cells were detected. Top Keywords Pituitary, Pangasius pangasius, TEM, RPD, PPD. Top |
