Gross and Micro-Anatomy of the Spleen of Adult Indigenous Fowl of Assam

Abstract

The present investigation was conducted on spleen of apparently healthy ten adult indigenous fowl of
Assam, irrespective of sex. The spleen was located on the right side close to the junction of pro-ventriculus and
gizzard. It was reddish brown and slightly elongated and ovoid. The capsule was thick without distinct
trabeculae. The parenchyma revealed intermingling of red and white pulps with a framework of reticular fibres.
The white pulp was diffusely scattered throughout especially around the arterial branches. The red pulp was
made up of loose spongy tissue arranged in anastomosing cellular cords of mainly reticular cells surrounded by
venous sinuses. Macrophages, lymphocytes and erythrocytes were also observed. The venous sinuses were
irregular passages within the red pulp lined by flattened and elongated endothelial cells. Sheathed arteries were
also found in the red pulp.
