What is the matrix composed of in elastic cartilage quizlet?

What is the matrix composed of in elastic cartilage quizlet?

cartilage is a connective tissue consists of dense matrix of collagen fibers and elastic fibers embedded in a rubbery ground substance (hyaluronic acid, proteoglycans and small amount of several glycoproteins). The matrix is produced by cells called chondroblast, which become embedded in the matrix as chondrocytes.

What is elastic cartilage composed of?

Elastic or yellow cartilage contains elastic fiber networks and collagen fibers. The principal protein is elastin. Elastic cartilage is histologically similar to hyaline cartilage but contains many yellow elastic fibers lying in a solid matrix. These fibers form bundles that appear dark under a microscope.

What is the solid matrix of cartilage composed of?

The matrix of cartilage is composed of specialized cells called chondrocytes. The biochemical compose the solid matrix of cartilage is proteins and sugar.

What is the matrix composed of?

Two main classes of extracellular macromolecules make up the matrix: (1) polysaccharide chains of the class called glycosaminoglycans (GAGs), which are usually found covalently linked to protein in the form of proteoglycans, and (2) fibrous proteins, including collagen, elastin, fibronectin, and laminin, which have …

What cell produces the cartilaginous matrix?

What cell produces the cartilaginous matrix? The mature cell in cartilage is a chondrocyte. It rests in a lacunae surrounded by matrix. A chondroblast is an immature cartilage cell which produces the cartilaginous matrix.

How is the matrix of elastic cartilage and fibrocartilage different from the matrix of hyaline cartilage?

Hyaline cartilage contains fibers made primarily of type II collagen only. Fibrocartilage contains type II collagen but also contains abundant type I collagen. Elastic cartilage contains type II collagen and elastic fibers.

What is the name of the cartilage between the vertebrae and what is it composed of?

Fibrocartilage is a tough and inflexible form of cartilage found in the knee and between vertebrae.

What is the matrix of bone and cartilage made of Class 9?

Bone:It is very strong, non-flexible tissue, porous, highly vascular, its matrix is made up of proteins, heavily coated with P,Ca and Mg salts. These minerals are responsible for hardness of the bone. 1)It forms endoskeleton of human being and other vertebrates.

Is cartilage a sugar matrix?

Cartilage is made up of a special type of cell – chondrocytes. The solid matrix of fibrous cartilage tissue is made up of proteins and sugars. The sharks and human embryos are composed of cartilage.

Is matrix and cytoplasm the same?

The fluid portion of the cytoplasm is called the cytosol. It is the liquid matrix that surrounds the organelles inside the cell. The cytosol is sometimes referred to as the cytoplasmic matrix, cytomatrix, or cell matrix.

What are the two part major components in the matrix?

Two major components of the matrix are ground substance and protein fibers. This ground substance is usually a fluid (water), but it can also be mineralized and solid, as in bones.

Which of the following is composed of cartilage?

Cartilage is a connective tissue found in many areas of the body including: Joints between bones e.g. the elbows, knees and ankles. Ends of the ribs. Between the vertebrae in the spine.

What makes up the matrix of the cartilage?

As in other connective tissues, its matrix is composed of fibers (collagenous or elastic) and a ground substance that is rich in extracellular glycosaminoglycans (particularly the chondroitin sulfates). Cartilage is avascular, but its matrix is permeable to tissue fluids carrying nutrients and waste products.

How is elastic cartilage different from other connective tissue?

A form of connective tissue, elastic cartilage is also recognized by its ability to snap back into an original form – or resting form – due to the addition of elastin fibers to the extracellular matrix. This fiber type distinguishes elastic cartilage from all other forms.

How many chondrocytes are there in elastic cartilage?

The above image, multiplied in size by 100, clearly shows one, two, and very rarely three chondrocytes within a single lacuna inside the elastic cartilage. These chondrocytes are surrounded by the extracellular matrix crisscrossed by a darker, fibrous network of collagen and elastin fibers.

What kind of collagen is in articular cartilage?

Collagen type II is the predominant collagen in articular cartilage and is responsible for its tensile strength; however, other minor collagens, such as collagen types V, VI, IX, and X, are also present.
