Fibrous Shell

The fibrous membrane (tunica fibrosa; synonym fibrous capsule) is one of the membranes that forms the wall of a hollow organ. The fibrous membrane consists mainly of collagen and elastic fibers. It gives the organ strength and elasticity, and also determines its shape.

The fibrous membrane is the thickest part of the wall of organs such as the stomach, intestines, bladder, and uterus. In the heart, the fibrous membrane forms the fibrous rings to which the valve leaflets are attached. In the kidneys, a fibrous capsule covers the organ from the outside and sends deep into the septa that divide the parenchyma into lobules.

Thus, the fibrous membrane performs an important structural and protective function in the body, ensuring the integrity and normal functioning of internal organs.

The fibrous membrane is the dense connective tissue that surrounds and protects organs, blood vessels, nerve endings, and other structures within the body. It is important for maintaining the normal function of organs and systems.

Fibrous membranes are composed of collagen fibers, proteins that form the basis of connective tissue. They provide strength, firmness and elasticity to tissues, and also help maintain the shape and structure of organs.

Without sufficient fibrous lining, organs can become vulnerable to damage and infection. This can lead to various diseases, such as liver cirrhosis, ovarian cysts, appendicitis, myositis, etc.

Scientists have examined the functions of fibrous membranes in the body and found that they play a key role in maintaining normal metabolism, immune response and circulation. In particular, scientists focused on studying the fibrous membranes that surround the circulatory system.

Arterial fibrous membranes help maintain the elasticity and flexibility of the artery, allowing it to contract.
