Abstract
The adrenal glands are enclosed in two-layered capsule; an outer fibrous and an inner cellular layers. The cellular layer haselongated spindle shaped connective tissue cells. Originating from the capsule C. T. trabeculae. Clusters of cells resembled the cortical cells are present in capsule and clusters of cells which looked-like
medullary cells sometimes were found within the adrenal cortex
and trabeculae. Their appearance was definitely related to the
advancing of age. Adrenal cortex is structured in three different layers. The zona glomerulosa; the outer most layer. The zona fasciculata; the middle
layer, and the zona reticularis; close to the adrenal medulla. The zona glomerulosa cells were large cuboidal and arranged ill subcapsular glomeruli. The zona glomerulosa and its
parenchymal cells did not show any age demonstrable related
alterations in their growth, with the exception of increase in
lipofuscin pigment and increase thickness of the connective tissue
fibers. It appeared more vascular in young age than in the old one.
The zona fasciculata revealed its cells were arranged radially
in cords and were polygonal in shape. Very often binucleate cells
could be seen in advanced ages. The cells have many small lipid
DROPlets and peripherally distributed lipid g1dbU1es. ”’W”ith afivanellig
age the fasciculata cells appeared larger and engorged with large
