Description :
The present study shows the cyclical alternation in the activity of adrenal gland of the bat
Hipposiderous lankadiva
during sexually quiescence and sexually active period of the reproductive cycle.
The adrenal gland is made up of steroidogenic and chromaff
in cells. The gland during sexually quiescence
period is much smaller than that of sexually active period. The cortex is completely encircles the medulla
in
Hipposideros lankadiva.
The medulla in this species consists of epitheloid cells arranged in smalle
r
groups surrounded by blood capillaries. The Zona glomerulosa consist of numerous bulbous structures
which appear as acinus like group of cells. The Zona fasciculata is seen in the form of straight column;
one or two cells thick arranged radially that run
toward the center of the gland. These cords consist of
large polyhedral vacuolated cells. The Zona reticularis has the cells disposed in the form of anastomosing
cords and vary in shape and size. The cells are hypertrophied. Cytoplasm is eosinophilic with
darkly
stained nucleus and more vacuolated. Medulla is entirely surrounded by cortical zone it consist of groups
of chromatin cells separated by blood capillaries.
