What is cartilage matrix made of?
Cartilage is made up of specialized cells called chondrocytes. These chondrocytes produce large amounts of extracellular matrix composed of collagen fibres, proteoglycan, and elastin fibers.
What are the predominant components of the cartilage matrix?
Cartilage is a group of tissues produced by chondrocytes that is characterized by a relative lack of vascularity. It consists of cells surrounded by a specialized extracellular matrix composed predominantly of type II collagen and proteoglycans, often in the form of proteoglycan aggregate.
How is cartilage made?
Cartilage is formed from the mesoderm germ layer by the process known as chondrogenesis. Mesenchyme differentiates into chondroblasts which are the cells that secrete the major components of the extracellular matrix. The most important of these components for cartilage formation being aggrecan and type II collagen.
How are cartilage formed?
Cartilage is formed from the mesoderm germ layer by the process known as chondrogenesis. [5] Mesenchyme differentiates into chondroblasts, which are the cells that secrete the major components of the extracellular matrix—the most important of these components for cartilage formation being aggrecan and type II collagen.
What is the composition of cartilage matrix class 9?
The matrix of cartilage is composed of Glycosaminoglycans, proteoglycans, Collagen fibers and elastin. Cartilage performs the function of smoothening the bone surfaces at joint. Cartilage is also present in the nose, ear, trachea, and larynx.
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.
What are the matrices of bone and cartilage made up?
extracellular matrix
Cartilage and Bone are specialised forms of connective tissue. They are both made up of cells embedded in an extracellular matrix. It is the nature of the matrix that defines the properties of these connective tissues. Cartilage is thin, avascular, flexible and resistant to compressive forces.
What compounds do the bone hard matrix contain Class 9?
Bone cells are embedded in a hard matrix that is composed of calcium and phosphorus compounds. These compounds are responsible for the hardness of the bone tissue.
What is the matrix composed of in cartilage?
The matrix of cartilage is made up of glycosaminoglycans, proteoglycans, collagen fibers and, sometimes, elastin . Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body. Examples include the rings of the trachea, such as the cricoid cartilage and carina .
What are three types of cartilage and their functions?
It’s softer and more flexible than bone. Cartilage gives support and structure to other bodily tissues. It also helps to cushion your joints. There are three different types of cartilage in your body: hyaline cartilage, elastic cartilage, and fibrocartilage.
Which cells make up cartilage?
Cartilage is made up of specialised cartilage cells called chondrocytes. In elastic cartilage, they are organised into elastic fibers, which make up a threadlike network or matrix.
What are the different types of cartilage?
The main cell types in cartilage are chondrocytes, the ground substance is chondroitin sulfate, and the fibrous sheath is called perichondrium. There are three types of cartilage: hyaline, fibrous, and elastic cartilage.
