دراسة التركيب النسجي للطحال في طير السلوى Coturnix coturix coturnix L.

Abstract EN

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.
