The capsule of the spleen is a protective outer layer composed of dense fibrous tissue, elastic fibers, and smooth muscle.
Here's a more detailed breakdown:
-
Composition: According to references, the splenic capsule primarily consists of:
- Dense fibrous tissue: Provides strength and structural support.
- Elastic fibers: Allows for some degree of flexibility and expansion.
- Smooth muscle: Contributes to the spleen's ability to contract.
-
Outermost Layer: The outermost layer of the capsule is composed of mesothelial cells. These cells may not always be apparent in histological sections.
In essence, the capsule provides a structural framework and protective covering for the spleen's delicate internal tissues.
