Abstract:
:The gross relationships and light microscopic anatomy of the suprarenal gland of a prosimian primate, Galago senegalensis, is described. The left gland is located medial to the pole of the left kidney in a fascial compartment of its own. The right suprarenal is located medial to the pole of the right kidney in intimate apposition to the liver and inferior vena cava. The capsule of the right gland blends with the capsule of the right lobe of the liver and is also contiguous with the adventitia of the inferior vena cava. The histologic appearance of the gland is similar to that of other primate genera. The zona glomerulosa is poorly developed; the zona fasciculata is composed of cell cords and is relatively well developed and the zona reticularis shows no unusual characteristics. The organization of the lipid content of the various cortical zones show a considerable different pattern than previously reported. The zona glomerulosa contains numerous large lipid droplets. In contrast to the bi-laminar pattern of lipid deposition seen in other primates, the Galgo shows three distinct layers of lipid droplets in the zona fasciculata. The zona reticularis has a moderate population of lipid droplets essentially similar to that reported in most other forms. The medulla, except for a sparse number of centrally displaced zona reticularis cells, is completely devoid of lipid deposits. The junction of the zona reticularis and medulla is distinct, although a connective tissue capsule is not present.
