When compared to bone tissues, cartilage tissues are more flexible and elastic. Transcribed image text: 28. The perichondrium is a sheath of very dense connective tissue lining the outer part of the cartilage. Chondroblasts produces extracellular matrix composed of collagen fibers, abundant ground substance rich in proteoglycan, and elastin fibers. The elastic cartilage is one of the three types of cartilage that can be found in the human body. For example, the intervertebral disc of the spine has a thick circle of fibro-cartilage around the softer center of dense connective tissue, which is know as the nucleus pulposus. cellular matrix of elastic cartilage is predominantly made up of type II collagen, proteoglycans and elastin fibers [1]. ; The epiglottis projects upward beyond the larynx and well above the hyoid bone and is attached to the root of the .

Articular Cartilage is composed of cells called chondroblasts. Examples include adipose, cartilage, bone, blood, and lymph. Elastic cartilage is a structural cartilaginous tissue for non-load-bearing body parts, such as ears, nose, and epiglottis (Hutmacher et al., 2003). The elastin fibers are responsible for the yellowish appearance of the tissue and also provide it with high elasticity. 1.) Cartilage: It is tough, hard but a flexible connective tissue. But variations in the structure of each type of cartilage give them different characteristics. Blood Tissue The tissue present in the walls of the respiratory tract is another example of hyaline cartilage.

Thyroepiglottic Ligament, Hyoepiglottic Ligament, Glossoepiglottic Folds & Valeculae. Articular cartilage is just a type of tissue. It can act as a smooth surface for bone articulation within joints, play a role in bone formation, and also provide structural support, such as the cartilage rings in the trachea. It lines the bones in all joints, helping the body to move freely. The ears of most vertebrate animals contain this cartilage as do portions of the larynx, or voice box. Elastic cartilage: It contains elastin fibers, making it more flexible than other types of cartilage.

The meaning of ELASTIC CARTILAGE is a yellowish flexible cartilage having the matrix infiltrated in all directions by a network of elastic fibers and occurring chiefly in the external ear, eustachian tube, and some cartilages of the larynx and epiglottis. Fibrocartilage is tough and contains many more collagen fibers. It contains a large amount of elastin, which will give it a characteristic yellowish color and greater elasticity than hyaline and fibrous cartilage. Elastic fibres are found in the articular fibrous tissue of various joints, and in the fibrous perichondria of hyaline and fibrous cartilages. You'll find elastic cartilage in places like: The outer ear, The larynx or voice box, and The epiglottis, the movable flap that keeps food from entering the windpipe when swallowing. Locate the cartilage in this section of the epiglottis. Hyaline cartilage is flexible, elastic, and surrounded by a dense membrane called perichondrium. the elbows, knees, and ankles, ends of the ribs, Between the vertebrae in the spine, ears, and nose, Bronchial tubes or airways. The matrix of the hyaline cartilage consists of a translucent material called chodrin, which is mainly a mucopolysaccharide with combined sulphate groups. The example is from dog tissue. Supporting connective tissues have two types: cartilage and bone. The ground substance acts as a fluid matrix that suspends the cells and fibers within the particular connective tissue type. STRUCTURE: Elastic cartilage is histologically similar to hyaline cartilage but contains many yellow elastic fibers lying in a solid matrix. For example: nylon, latex, rubber, polyester. The Extracellular Matrix of Elastic Cartilage The ECM of elastic cartilage contains elastin, fibrillin, glycoproteins, collagen types II, IX, X and XI, and (predominantly) the proteoglycan Aggrecan. Elastic Cartilage: Characteristics, Histology, Functions. Moreover, the walls of the medial part of the auditory canal is made up of elastic cartilage. These components are produced by the chondroblasts at the inner edges of the perichondrium, and are located in an environment that is gel-like. Elastic Cartilage This is a section of epiglottis that has been treated with a special stain for elastic fibers, so the cells and tissues will have different color than in an H&E-stained sample. The overall elastic potential articular cartilage, seen as a composite with a continuous infinity of fiber families, is obtained via rule of mixture, i.e., . It is a mixture between dense regular connective tissue (similar in many respects to tendon or ligament) and hyaline cartilage. It is present in the outer ear or pinna, Eustachian tube, and epiglottis Which provides strength and maintain the shape. It is sensitive to heat and cold because the extracellular matrix does not have a high tolerance for temperature changes. (a) Hyaline cartilage provides support with some flexibility. The external ear is an example of elastic cartilage, and the meniscus and annulus fibrosus of the IVD, which will be discussed later, are examples of fibrocartilaginous tissues. The nose. 3. It is present in the ear pinna, external auditory meatus, Eustachian tubes, and epiglottis etc. In contrast, the fibrocartilage found in the glenoid or acetabular labra are more resistant to repetitious stress and provide strength and elasticity to the musculoskeletal attachment. .
