The structure of the zona reticularis, medullary capsule, F-zone and medulla of the African elephant (Loxodonta africana) is described. Three types of cells, arranged as described in other mammals, are found in the zona reticularis. Organelles in this zone are as descibed for other cells that secrete steroids. The ultrastructure of the cells in the F-zone is very similar to that of cells that secrete steroids. Two types of cells, roughly similar to those of other mammals, are found in the medulla
