2. Cartilage or cartilaginous tissue is a resilient and type of connective tissue of mesodermal origin that forms an integral part within the musculoskeletal system and as a structural component in other organs. Cartilage is an important structural component of the body. In fibrocartilage histology, you will find the same structure (cells, fibers, and ground substances) that you have seen in others cartilage histology.Here, I will enlist the important structures you might identify from the fibrocartilage histology slide under a light microscope. Hyaline cartilage which surrounds the articular surfaces and allows for painless movement of synovial joints by reducing friction is composed of chondrocytes embedded within an extracellular matrix made up of a macromolecular framework and water. Hyaline Cartilage: Present at the end of ribs and in the nose, it is the second most flexible type of cartilage. It contains no nerves or blood vessels, and its structure is relatively simple. Fibro- is found in invertebral discs, joint capsules, ligaments. Verified. Provides stiff, yet flexible support**. Elastic cartilage has a high concentration of elastin fibers arranged in an extracellular matrix structure, and unlike hyaline cartilage, it does not calcify for the formation of bones. It is the most widespread cartilage type and, in adults, it forms the articular surfaces of long bones, the rib tips, the rings of the trachea, and parts of the skull. The extracellular matrix of hyaline cartilage histology is homogenous and glassy in appearance. Aggrecan is the most abundant proteoglycan in hyaline cartilage; hundreds of these aggrecans are bound noncovalently by link proteins to long polymers of hyaluronic acid. Fibrous cartilage has lots of collagen fibers and is found in dense tendon and ligament tissue. Structure. It is 2 to 4 mm thick in people.

Draw a neat labelled diagram of Hyaline Cartilage. * This is the most widespread type of cartilage—other locations include: ends of long bones; cartilages of the nose, larynx, and trachea. #1. Hyaline cartilage is a kind of articular cartilage. It sometimes blends in with the following cartilage, depending on the structure of the trachea. Hyaline cartilage is found at this structure. Costal cartilages*. Cartilage is further classified into three main groups on the basis of the composition of the matrix. It is also most commonly found in the ribs, nose, larynx, and trachea. Chondrocyte. Functions of hyaline cartilage • Articular cartilage provides smooth surface for movement at joints • Though it is flexible, it provides support because of its firmness • Firmness of the cartilage keeps the lumen of trachea and bronchi patent 19. Fibrocartilage histology. Cartilage: The three types of cartilage There are three types of cartilage: Hyaline - most common, found in the ribs, nose, larynx, trachea. Hyaline Cartilage -. It is a strong but flexible tissue that is strengthened by fine collagen fibers (Cartilage Types 04/20/17). The initial generations of the bronchi are similar to each other in their histologic structure, except for the amount of hyaline cartilage. Description: This is a section of hyaline cartilage, the most abundant type of cartilage in the body. Depending on location, cartilage can have different ratios of collagen to proteoglycans. The bar shows you the extent of the cartilage in the tracheal wall. Depending on location, cartilage can have different ratios of collagen to proteoglycans. Joint and Structure and Function By Dave Fajardo, BSPT-2A • Joints are often used to connect different segments together and often allow movements between those segments • Follows the principle of: Form follows function • Object’s composition, its structure and a change in the structure of material can affect function Composition of joints is determined by factors … In joint: Articular cartilage. The extracellular matrix contains varying amounts and types of connective tissue fibers, giving rise to three main types of cartilage: hyaline, elastic, and … Hyaline cartilage. Additionally, it participates in the modulation of voice and serves as the attachment point for several ligaments and muscles of the larynx and neck. Cartilage is of three types: Elastic Cartilage: Found in the ear, as it is the most flexible type. Anatomy and Physiology questions and answers. outer covering of a chondrocyte. elastic cartilage. outer covering of a chondrocyte. Fibrous- outer, dense irregular connective tissue. #1. Hyaline Cartilage. The extracellular matrix (ECM) of hyaline cartilage is homogeneous and glassy, rich in in type II collagen, proteoglycans such as aggrecan, and structural glycoproteins such as chondronectin. It is predominately collagen and contains no nerves or blood vessels, and its structure is relatively simple. It is one of the most abundant types of cartilage found in the human body. Its collagen building blocks are mainly of the type II variety. Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis. Lacuna. Glassy and light blue in appearance , the articular cartilage layer is 2–4 mm thick contingent on its location. The articular cartilage interface can be divided into four zones: superficial, middle, deep, and tidemark. Costal cartilages*. fibrocartilage. Here we show that in conjunction with ultrastructural, and high-magnification … hyaline cartilage - hyaline cartilage stock illustrations. Nucleus. Hyaline cartilage is the most common kind, and forms fetal skeleton and joint surfaces. Hyaline cartilage. [1] Hyaline cartilage is pearl-grey in color, with a firm consistency and has a … Browse 9 hyaline cartilage stock illustrations and vector graphics available royalty-free, or search for elastic cartilage or fibrocartilage to find more great stock images and vector art. Hyaline cartilage 100X You can begin to see the details in hyaline cartilage (hc) structure in this image. It differs from normal hyaline cartilage in that the chondrocytes at the surface are flattened. a. Hyaline Cartilage. It is normally found on surfaces of joints and in the cartilage making up the fetal skeleton. As in the trachea, the cartilage helps keep the bronchial wall from collapsing. Read More. The cartilage and mucous membrane of the primary bronchi are similar to that in the trachea. The fibrocartilage is found in the meniscus (cartilaginous discs) between the joints and in ligaments. Cartilage can be generally classified into the following main types: hyaline cartilage. Due to its avascular, aneural, and hypocellular structure, its response to trauma is very restricted. This forms three categories of cartilage: hyaline cartilage, yellow elastic cartilage and white fibrous cartilage. 11 terms. Introduction: cartilage structure and function Cartilage is an avascular, aneural, alymphatic connective tissue found in the synovial joints, spine, ribs, external ears, nose, and airways, and in the growth plates of children and adolescents. Hyaline cartilage has a pearly bluish-white tinge and under a low-power microscope the matrix appears amorphous and translucent (semitransparent) as in Figure 11.Under a high-power microscope the matrix can be seen to consist of a dense network of very fine collagen fibrils and fibers embedded in proteoglycan gel (Setton et al., 1999).Most of the skeleton is preformed in … cartilage cell enclosed by lucana. Hyaline Cartilage. The cricoid is the Greek word for the ring. Deep to the mucosa is a layer containing smooth muscle fibers, hyaline cartilage, and scattered seromucous and mucous glands. The bronchial wall is made up of mucosa, lamina propria, smooth muscle, and submucosa with interspersed cartilage. Fibrocartilage histology. The word hyaline is taken from Greek word translucence, and cartilage is referred with this name because of its similar structure. Hyaline cartilage is covered externally by a fibrous membrane, called the perichondrium, except at the articular ends of bones; it also occurs under the skin (for instance, ears and nose). The membranes facilitate diffusion, and thus supply the cartilage with nutrients. The perichondrium surrounding the cartilage is composed of two layers: 1. Hyaline cartilage is a firm structure that has collagen. The amorphous ground substance of a hyaline structure is generally firm and contains a collagen fiber network (type II). However, cartilage is composed of type II. Perichondrium is mainly found on the surfaces of elastic and hyaline cartilage, which can be found in multiple locations of the body, such as in the ears, nose, joints and ribs. Cartilage is a specialized, semi-rigid connective tissue characterized by the predominance of a glycosaminoglycan and proteoglycan-rich ground substance that attracts water, giving this tissue a high degree of hydration. This type of elastic cartilage is seen in the ears and larynx (voice box). There are three unique types of cartilage in the body and they each serve a different functional purpose. The Articular Cartilage Of A Typical Long Bone Is Composed Of What Type Of Cartilage?hyaline cartilageWhat type of cartilage is articular cartilage?hyaline cartilageArticular cartilage is hyaline cartilage and is 2 to 4 mm thick. The nasal cartilages provide structure and support to the nose. It is a simple structure with no blood vessels or nerves. Types of Cartilage Hyaline Cartilage. Unlike most tissues, articular cartilage does not have blood vessels, nerves, or lymphatics. As mentioned before, hyaline cartilage contains a lot of collagen; it contains type II, specifically. forms tracheal rings, part of larynx, and surfaces of bones. This rapidly growing tissue forms the majority of the fetal skeleton and remains into adulthood as the smooth joint surfaces at the ends of moveable articulating bones. As you know that the it is the hyaline cartilage. It persists in human adults at the ends of bones in free-moving joints as articular cartilage, at the ends of the ribs, and in the nose , larynx, trachea, and bronchi. Hyaline cartilage is a vital component of epiphyseal growth plates, which regulates the growth as well as shape of long bones soon after birth till adolescence. It has a pale blue-white color and is smooth to the touch. Related Biology TermsCartilage – Tough but flexible connective tissue found in places such as the nose, ear, joints, and respiratory system.Collagen – A protein that is found in skin and connective tissue; it is the most common protein in the human body.Fiber ( anatomy) – An elongated filament found in connective tissue.More items... It also forms the skeletal framework of the larynx, the … It is also found in the rib cage, joints, nose, ear, and the pubic symphysis (joint). There are three major types of cartilage found in humans: hyaline, fibrous and elastic [1](seeFig. Here, it provides elasticity, protection, and stability. In the fetus, a provisional skeleton is created by hyaline cartilage, which during the process of endochondral bone formation is replaced by bone. Hyaline cartilage is the most abundant in the body and surrounded by perichondrium. As the branching continues through the bronchial tree, the amount of hyaline cartilage in the walls decreases until it is absent in the smallest bronchioles. Hyaline cartilage is a type of connective tissue found in areas such as the nose, ears, and trachea of the human body. sofievball_39. You will find the pericellular, territorial matrix and interterritorial matrix in the hyaline cartilage structure. Several types of cartilage are found in the human body, and their structure and relevant function depend on this variation. Lacuna. characteristics Hyaline cartilage contains a single type of cell made up of chondrocytes, while the matrix is made up mainly of type II collagen fibers and chondroitin sulfate. The name hyaline comes from the pearly coloration of the fabric and its appearance that resembles a frosted crystal. STRUCTURE: Hyaline cartilage is covered externally by a fibrous membrane, called the perichondrium, except at the articular ends of bones and also where it is found directly under the skin, i.e. Hyaline cartilage is the glass-like and translucent cartilage found on many joint surfaces. It is found in the embryonic skeleton, the cartilage of the ribs, joints, and nose, the large laryngeal cartilages, and the cartilages of the trachea (Fig. Hyaline cartilage is the most widespread and is the type that makes up the embryonic skeleton. It is mostly made up of collagen (type II) with relatively few elastic fibres and is surrounded by a perichondrium. The nasal cartilages provide structure and support to the nose. As the cartilage decreases, the amount of smooth muscle increases. The water bound to the structure enables the cartilage to act as a shock absorber. The chondrocytes are fixed in the lacunae and unable to migrate to repair damaged areasCartilage is avascular and relies on diffusion, so the deposition of new cartilage is often very slowDamaged hyaline cartilage is often replaced with fibrocartilage which is not as well suited to the function of cartilage at that site It contains no nerves or blood vessels, and its structure is relatively simple. Hyaline cartilage is the most copious type of cartilage in the human body. Hyaline cartilage is covered externally by a fibrous membrane, called the perichondrium, except at the articular ends of bones; it also occurs under the skin (for instance, ears and nose). Cartilage consists primarily of water, which accounts for its resilience, that is, its ability to spring back to its original shape after being compressed. Much of what is known regarding dynamics and function of cartilage constituents has been derived or inferred from biochemical and electron microscopic investigations. Cartilage is a soft, elastic and flexible connective tissue that protects the bone from rubbing against each other. Mobile PDFOptimized for tablets (5.5" x 8.5") Printable PDFOptimized for printing (8.5" x 11") Hyaline cartilage Forms canals for blood vessels Protects cortical bone Resists mechanical stress Stores bone marrow Weighs less Components of hyaline cartilage. With the use of an ample spectrum of strongly T1- to T2-weighted sequences, two zones of cartilage with different signal intensities were observed in all specimens. Hyaline cartilage is the most widespread type and resembles glass. The Hyaline cartilage is the most common type of cartilage and forms the cartilages of the ribs that join at the sternum (costal cartilages). In the embryo, bone begins as hyaline cartilage and later ossifies. It is primarily composed of type II collagen and proteoglycans. Found in adults in the diaphysis B.
