What is the function of elastic connective tissue?
Elastic Connective Tissue The main fibers that form this tissue are elastic in nature. These fibers allow the tissues to recoil after stretching. This is especially seen in the arterial blood vessels and walls of the bronchial tubes.
What cells produce elastic fibers?
Elastic fibers (or yellow fibers) are an essential component of the extracellular matrix composed of bundles of proteins (elastin) which are produced by a number of different cell types including fibroblasts, endothelial, smooth muscle, and airway epithelial cells.
Why is collagen Acidophilic?
The matrix is acidophilic because of the large amount of coarse type I collagen fibers . Note that there are relatively few cells when compared with hyaline cartilage.
What are elastin Fibres?
Elastic fibres are essential extracellular matrix macromolecules comprising an elastin core surrounded by a mantle of fibrillin-rich microfibrils. They endow connective tissues such as blood vessels, lungs and skin with the critical properties of elasticity and resilience.
What is the function of connective tissue explain its types?
Tissue that supports, protects, and gives structure to other tissues and organs in the body. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue. Connective tissue is made up of cells, fibers, and a gel-like substance.
Why elastic fibers are yellow?
The main constituents of yellow elastic tissue are many freely-branching elastic fibres (which are responsible for the yellowish colour of the tissue). Chemically, the elastic fibres are elastin, which is composed of the amino acids glycine, valine, alanine, and proline.
What are elastin fibers made of?
In the body, elastin is usually associated with other proteins in connective tissues. Elastic fiber in the body is a mixture of amorphous elastin and fibrous fibrillin. Both components are primarily made of smaller amino acids such as glycine, valine, alanine, and proline.
What is the function of elastic fibers in the skin quizlet?
The collagen and elastic fibers provide strength, extensibility (ability to stretch), and elasticity (ability to return to original shape after stretching) to skin.
Is collagen Acidophilic or basophilic?
Collagen fibers (typically type I collagen) are acidophilic when stained with H & E, as seen in the dermis of skin. They tend to have a wavy appearance and may be sectioned obliquely, transversely or longitudinally. Nuclei of fibroblasts (fibrocytes) are numerous among the collagen fibers.
What is the function of fibrocartilage?
Fibrocartilage provides the tough material of the intervertebral discs; the intraarticular cartilages of the knee, wrist and temporo-mandibular joints; the articular cartilage of the temporo-mandibular joint and of the joint between the clavicle and the sternum.
Why is elastin elastic?
Elastin is a key extracellular matrix (ECM) protein that provides resilience and elasticity to tissues and organs. Elastin is roughly 1000 times more flexible than collagens; thus, the main function of elastin is the elasticity of tissues. Elastin monomers are crosslinked during the formation of desmosine molecules.
What is collagen elastin?
Elastin and collagen are both proteins found in skin. They work together to give skin its texture and shape. Skin with healthy levels of both collagen and elastin isn’t just more youthful; it’s stronger.
