Cellular exploration of pars distalis adenohypophysis in mature and immature male and female rabbit (Oryctolaguscuniculus)

Abstract

To study the cellular details of Pars distalis adenohypophysis of pituitary gland twelve healthy immature and mature rabbits were utilized. The pars distalis adenohypophysis comprised of cells arranged in irregular cords, grouped as acidophils, basophil and chromophobes. Type I Acidophils were usually round or oval and rarely elongated with distinct outlines its rounded nuclei were eccentrically placed. Type II acidophils were rounded, irregular polygonal and rarely elongated with densely granulated cytoplasm. The cytoplasm of Type I Basophil found densely granulated with coarse granules. Type II basophils were irregularly rounded, oval or angular with rounded nuclei and cytoplasm showed fine granules. The chromophobes were weakly stained and sparsely distributed throughout the adenohypophysis pars distalis. The size of the cells was observed that Type I acidophils were largest followed by Type II aciodophil, Type I basophil and type II basophils. Sexual and age-related variations were not noticed.
