Damage To The Fibrous Tissues Is One Of The Reasons For Erectile Dysfunction
Fibrous tissues are mostly connective tissues which forms a continuous mesh around the endomysium of an individual’s muscle fibers to the larger layers of perimysium that delineate into bundles of muscle fibers. These bundles of muscle fibers are gathered and connected to the strong thick epimysium on the surface of the muscles. There are two types of protein fibers known as Collagen and Elastin in the muscles.
Damage to the fibrous tissues is one of the reasons for erectile dysfunction and it might warrant treatment with viagra.
Collagen is an elongated protein that forms extremely strong but very small fibrils. Lots of these collagen fibrils are bound together to form collagen fibers. Usually large amount of collagen are found in animal skin. Collagen is the most abundant protein in the animal body, and the collagen which occurs in meat may be an important source of meat toughness. These collagen fibers when form sheets or cables we can see them in the meat. Collagen fibers are connective tissue framework of meat range 1 to 12 micrometer in diameter. They do not often branch. Collagen fibrils are formed from long tropocollagen molecules which are staggered in arrangement but tightly bound laterally by covalent chemical bonds. Tropocollagen is a high molecular weight protein formed from three polypeptide strands twisted into a triple helix. This triple helix is responsible for the stability of the molecule. There are various types of collagen structures are useful in understanding the structure of the meat. Type 1 collagens are seen in blood vessel walls, tendon, bones, skin and meat. It may be synthesized by fibroblasts, smooth muscle cells and osteoblasts. Type 2 collagen fibers occur in hyaline cartilage and in intervertebral disc. It is synthesized by chondrocytes which are the cartilage forming cells. Type 3 collagen forms reticular fibers in tissues and seen in spleen, aorta and muscle. It is synthesized by fibroblasts and smooth muscle cells. Type 4 occurs in the basement membranes around any type of cells and may be produced by the cells themselves. Type 5 collagen is found in basement membrane and in the cultures of embryonic cells. Type 6 collagen is seen in muscles and skin.
All arteries from the aorta down to the finest microscopic arterioles rely on fibers which have elastic property and they are called as elastin fibers to accommodate the surge of blood from contraction of the heart. Elastin fibers may be stretched to several times their original length but rapidly resume their original length once released. It is found in all vertebrates except primitive jawless fish. Elastic fibers are made of the protein elastin. There are only few elastic fibers in muscles. The elastin fibers in muscles that are used frequently fro locomotion are larger and more numerous than those of less frequently used muscles. Elastin is synthesized by arterial smooth muscle cells, but the origin of elastin in non-vascular locations is not properly understood. Elastic fibers are usually pale yellow. Elastin filaments are bound by non-covalent interactions to form a three-dimensional network and elastic fibers are assembled in grooves on the fibroblast surface where initially rope-like aggregations of fibrils become infiltrated with amorphous elastin
