What Is A Reticular Fiber In Human Anatomy?

What are reticular Fibres and what is their function?

Reticular fibers crosslink to form a fine meshwork (reticulin). This network acts as a supporting mesh in soft tissues such as liver, bone marrow, and the tissues and organs of the lymphatic system.

What is the purpose of reticular fibers?

Reticular fibers crosslink, forming a fine meshwork. The reticular connective tissues are found in the kidney, the spleen, lymph nodes, and bone marrow. Their function is to form a stroma and provide structural support, such as that in the lymphoid organs, e.g. red bone marrow, spleen, and lymph node stromal cells.

Where are reticular fibers?

Location. Reticular connective tissue is found around the kidney, liver, the spleen, and lymph nodes, Peyer’ patches as well as in bone marrow.

What characteristics are used to distinguish reticular fibers?

Reticular fibers are highly branched, delicate, argyrophilic fibers that stain with ammoniacal silver solutions. Electron microscopic studies have shown that they are young collagen or a small bundle of collagen fibrils.

What is the difference between collagen and reticular fibers?

Collagen fibers are the strongest and thickest protein fibers found abundantly in the connective tissue. Elastin fibers are thinner fibers which can stretch and recoil while reticular fibers are highly branched delicate fibers found in organs that have lots of mesh-like structures.

What does reticular mean?

1: reticulate sense 1 reticular connective tissue containing collagen fibers. 2: intricate.

What is meant by reticular fibers?

Reticular fibre, in anatomy, fine fibrous connective tissue occurring in networks to make up the supporting tissue of many organs. The reticular fibres are composed of randomly oriented collagenous fibrils lying in an amorphous matrix substance.

How are reticular fibers formed?

In almost all instances, reticular fibers and tissue are produced by fibroblasts. The exception are lymphoid organs and structures, in which reticular cells are responsible for the synthesis. They are a special type of fibroblasts with a variety of additional functions.

Is reticular fiber a protein?

Reticular fibers, the third type of protein fiber found in connective tissues, consist of thin strands of collagen that form a network of fibers to support the tissue and other organs to which it is connected.

What cells produce reticular fibers?

The cells that make the reticular fibers are fibroblasts called reticular cells. Reticular connective tissue forms a scaffolding for other cells in several organs, such as lymph nodes and bone marrow.

Are reticular fibers in cartilage?

Type II – found in hyaline and elastic cartilage and in vitreous body of eye. Type III – found in reticular fibers, healing wounds, smooth muscle, and fetal skin. Type V – found in placental basal laminae, tendon, and muscle sheaths. Reticular fibers – form network of fibers.

Is reticular tissue cartilage?

The major types of connective tissue are connective tissue proper, supportive tissue, and fluid tissue. Loose connective tissue proper includes adipose tissue, areolar tissue, and reticular tissue. Cartilage and bone are supportive tissue. Cartilage contains chondrocytes and is somewhat flexible.

What are 3 types of connective tissue?

There are three main groups of connective tissues: loose connective tissue, dense connective tissue, and specialized connective tissue.

What are the 7 types of connective tissue?

7 Types of Connective Tissue

  • Cartilage. Cartilage is a type of supporting connective tissue.
  • Bone. Bone is another type of supporting connective tissue.
  • Adipose. Adipose is another type of supporting connective tissue that provides cushions and stores excess energy and fat.
  • Blood.
  • Hemapoetic/Lymphatic.
  • Elastic.
  • Fibrous.

What do all connective tissues have in common?

Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of amorphous ground substance, and protein fibers.
