Abstract
The present study revealed that the spleen of the quail is coated by afibrous capsule have two distinct layers , an outer and inner , the capsule being covered by athin layer of peritoneal membrane . The spleen comprises two distinct regions , the white pulp and red pulp in addition spares or trabecule . The white pulp represernt the major part of the organ , it is alymphatic tissue that could be differentiate into two forms : diffuse and nodular lymphatic tissue with medium and small size arteries represent the branches extend from the large trabecular arteries . Then these arteries branch into arterioles surrounded by sheath of reticular and lymphatic cells called Schweigger Sediel sheath . The red pulp has randomly distributed between the white pulp regions , it consist of cellular cord that surround the venous sinuses which had irregular shape lined endothelial cells separated by small gaps freely . The capsule consist of two layer , an outer layer that represent large collagen fiber while the inner layer represent large muscular fiber , thus the marginal zone between the white and red pulp is absent . the ellipsoid body was present in the white pulp more than the red pulp . In this study there are two type of nodules , type T nodule and type B were present . The percentage of the first nodular type is more than the second , which is the important character of the spleen of quail differ from other fowl .
