Cartilage Skeletal System Cartilage – Introduction, Structure, Formation And Types Of Cartilage . Choose from 425 different sets of function of elastic cartilage flashcards on Quizlet. Elastic or yellow cartilage contains elastic fiber networks and collagen fibers. temporal mandibular joint: A joint of the jaw that connects it to the temporal bones of the skull. For one, the primary cell types are chondrocytes as opposed to osteocytes. Elastic cartilage is similar to hyaline cartilage but also contains elastic fibers. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. There are three major types of cartilage: hyaline cartilage, fibrocartilage, and elastic cartilage. As animal gets old, hyaline cartilage loses water content and necrotic areas may appear in the central parts of the cartilage. It takes the form of a matrix and contains proteins, sugars and collagen. Its role is to give shape and support to these areas. Some lacunae are organised into pairs and are divided by a fine plate of matrix. Elastic cartilage. Elastic cartilage is springy, yellow, and elastic and is found in the internal support of the external ear and in the epiglottis. Cartilage types: Images of microscopic views of the different types of cartilage: elastic, hyaline, and fibrous. In the embryo, bones form first as hyaline cartilage before ossifying as development progresses. It is found in the epiglottis (part of the larynx), the pinnae (the external ear flaps of many mammals). Function: GIves support and maintains shape. Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. Watch the recordings here on Youtube! In contrast, fibrocartilage contains a large amount of collagen fibers, giving the tissue tremendous strength. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. Elastic cartilage locations are varied. In the embryo, bone begins as hyaline cartilage and later ossifies. hyaline cartilage: A type of cartilage found on many joint surfaces; it contains no nerves or blood vessels, and its structure is relatively simple. Elastic cartilage , sometimes referred to as yellow fibrocartilage, is a type of cartilage that provides both strength and elasticity to certain parts of the body, such as the ears. Elastic cartilage has to be specially stained to show the elastic fibers. Moreover, the walls of the medial part of the auditory canal is made up of elastic cartilage. Cartilage is one of the body's chief connective tissues. Articular cartilage function is dependent on the molecular composition of its ECM, which consists mainly of proteoglycans and collagens. Hyaline cartilage is the most widespread type and resembles glass. Elastic cartilage has a large amount of elastic fibers, giving it tremendous flexibility. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The elastic cartilage contains type II collagen fibers while the elastic connective tissue mostly contains type I collagen fibers. Elastic Cartilage What is its function? Elastic cartilage is springy, yellow, and elastic and is found in … The remodeling of cartilage is predominantly affected by changes and rearrangements of the collagen matrix, which responds to tensile and compressive forces experienced by the cartilage. Therefore to avoid confusion, a Verhoeff van Gieson stain is often used as this stains elastic fibers black. Have questions or comments? This plate can be clearly seen between the two lacunae. Read more. Elastic cartilage, sometimes referred to as yellow fibrocartilage, is a type of cartilage that provides both strength and elasticity to certain parts of the body, such as the ears. Elastic cartilage is found predominately in the external ear and as well as around the epiglottis. Elastic cartilage. Some specific stains include: Grounded on academic literature and research, validated by experts, and trusted by more than 1 million users. Elastic cartilage supports structures subjected to frequent deformation, including the larynx, epiglottis, and external ear. Unlike hyaline cartilage, which calcifies with aging, the matrix of elastic cartilage does not calcify during the aging process. When elastic cartilage is stained, you can see its elastic fibers.

In elastic cartilage, chondrocytes are organised into elastic fibers, which make up a threadlike network or matrix. In elastic cartilage, the chondrocytes are found in a threadlike network of elastic fibres within the matrix. If you really need it then let me inform or email me. When stained, the main components of elastic cartilage appear dark blue. CHAPTER 5: Cartilage.
