Abstract
The present study revealed that the spleen of the quail is coated byafibrous capsule have two distinct layers , an outer and inner , the capsule beingcovered by athin layer of peritoneal membrane . The spleen comprises twodistinct 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 tissuethat could be differentiate into two forms : diffuse and nodular lymphatic tissuewith medium and small size arteries represent the branches extend from thelarge trabecular arteries . Then these arteries branch into arterioles surroundedby sheath of reticular and lymphatic cells called Schweigger Sediel sheath .The red pulp has randomly distributed between the white pulp regions , itconsist of cellular cord that surround the venous sinuses which had irregularshape lined endothelial cells separated by small gaps freely .The capsule consist of two layer , an outer layer that represent largecollagen fiber while the inner layer represent large muscular fiber , thus themarginal zone between the white and red pulp is absent . the ellipsoid body waspresent in the white pulp more than the red pulp . In this study there are two typeof nodules , type T nodule and type B were present . The percentage of the firstnodular type is more than the second , which is the important character of thespleen of quail differ from other fowl
Highlights
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 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, 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
Summary
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.
