The extracellular matrix of elastic cartilage contains higher levels of type II. The extracellular matrix of elastic cartilage is less abundant than in hyaline cartilage.
Each serves specific functions within the musculoskeletal system.
Histology of elastic cartilage. In elastic cartilage histology you might describe the cells of elastic cartilage fibers and ground substance of elastic cartilage matrix of cartilage. Cells of elastic cartilage structure You will also find the same chondrocytes in the lacunae of the elastic cartilages matrix. Histology - Elastic cartilage View Related Images.
This section of elastic cartilage is from cartilage of the auricle external ear. Elastic cartilage consists of chondrocytes dispersed in a threadlike network of elastic fibers. It is a flexible tissue that can be easily deformed but.
In slide 053 the elastic fibers stain black whereas the rest of the matrix is yellow-brown. Elastic cartilage can be readily identified in routine HE sections as well as shown in slide 044H which is from the epiglottis. Look for the plates of elastic cartilage found just under the.
In elastic cartilage the chondrocytes are found in a threadlike network of elastic fibres within the matrix. Elastic cartilage provides strength and elasticity and maintains the shape of certain structure such as the external ear. It has a perichondrium.
This is a diagram of elastic cartilage. EC elastic cartilage. The Matrix of Elastic Cartilage is criss-crossed by numerous branched elastic fibers rich in the protein Elastin.
These elastic fibers lend a high degree of flexibility and resilience to the Matrix endowing it with what polymer chemists call memory When bent Elastic Cartilage will rapidly bounce back to its original form. Figure A is a low-magnification electron micrograph of a cross section cut through the external. Elastic cartilage contains collagen and an abundance of elastic fibres that are arranged into a threadlike network in which chondrocytes can be found.
It is resilient flexible and found in structures that are commonly deformed for example the outer ear larynx and epiglottis. Same except have more elastic fibers. GAG s PG gp - extensive cross-linking core proteins of PG linked to chains of hyaluronic acid - GAG chains of proteoglycan very hydrated tissue all water give resiliency.
Elastic cartilage Chondrocytes in elastic cartilage are larger and more numerous than in hyaline cartilage and form fewer isogenous groups. The extracellular matrix of elastic cartilage is less abundant than in hyaline cartilage. This special stain demonstrates the abundant elastic fibers in the matrix.
Histology of Elastic Cartilage. Elastic cartilage has elastic fibers in the matrix. Elastic cartilage is sometimes referred to as yellow cartilage.
Elastic cartilage is found in the external ear. Histology hint from Sarah Bellham. If you bend your ear forward it bounces back into its proper position.
This is due to the elastic cartilage. These images compare the appearance of elastic cartilage stained with hematoxylin and eosin left and hematoxylin and eosin plus orcein for elastic fibers on. Elastic cartilage sometimes referred to as yellow fibrocartilage is a type of cartilage that provides both strength and elasticity to certain parts of the.
The body is composed of three primary types of cartilage. Elastic fibro- and hyaline cartilage. Each serves specific functions within the musculoskeletal system.
Elastic cartilage is a structural cartilaginous tissue for non-load-bearing body parts such as ears nose and epiglottis Hutmacher et al 2003. It typically does not experience high mechanical loads for prolonged periods of time. Elastic cartilage Figure 8 is very springy and yellow and is found in the epiglottis the external ear and the larynx.
It consists of fiber bundles that appear dark under the microscope and has many disc-shaped cells interspersed throughout that are white in color. Elastic cartilage is similar in appearance to hyaline cartilage. The only way you can tell them apart is by staining the elastic fibres orcein stain.
Elastic fibres predominate in the ECM. Elastic cartilage is found in areas that require flexible support eg. Ear epiglottis nose etc.
It has a perichondrium. All the histological features of chondrocytes are similar to the chondrocytes of hyaline cartilage or elastic cartilage. You will find the similar size of chondrocytes and lacunae on the matrix in the fibrocartilage histology slide.
Matrix of fibrocartilage histology. Elastic cartilage is a structural cartilaginous tissue for non-load-bearing body parts such as ears nose and epiglottis Hutmacher et al 2003. It typically does not experience high mechanical loads for prolonged periods of time.
Histology of Elastic Cartilage How to Draw - YouTube. Step by step drawing of elastic cartilage how to Draw Elastic Cartilage histology journal if you like Elastic Cartilage. Cartilage is an avascular smooth and elastic tissue with various forms that allow it to function in a variety of ways.
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. Elastic cartilage - elastic fibers and type II collagen. Fibrocartilage - type I and II collagens.
Cartilage is avascular and its cells rely on diffusion for nutrients. Because of this damaged cartilage heals poorly after injury. Hyaline cartilage contains type II collagen fibers and a highly-hydrated ground substance.
It is the most common cartilage and is found on articular surfaces of bone walls of. Elastic cartilage looks very similar to hyaline cartilage under a microscope and special stains must be used to show the otherwise invisible elastic fibers that give this particular cartilage type its nameLike hyaline elastic cartilage also has single or multiple chondrocytes housed within spaces called lacunae. The extracellular matrix of elastic cartilage contains higher levels of type II.
