Articular cartilage locations are found throughout the body. The cells are called chondrocytes (ch) and the spaces in the cartilage in which they are found are called lacunae. of already knowing this is connective tissue, focus the groups of 2 to 4 cells (b) in the tiny space, surrounded by the homogeneous-looking matrix (c) without any visible collagen fibers. Bars of hyaline cartilage (the costal cartilages) connect ribs to sternum. Hyaline cartilage contains type II collagen fibers and a highly-hydrated ground substance. This fluid is moved into and out of the hyaline cartilage by movement of the joint that changes the pressures inside the joint, forcing the nutrients into the hyaline cartilage. Hyaline cartilage. Fibrous cartilage is … Elastic Cartilage - epiglottis - external ear - eustachian tube Hyaline Cartilage - thyroid cartilage of the larynx - tracheal rings - ends of long bones - nasal septum Fibrocartilage - intervertebral discs - articular surface in the knee (menisci) - pubic symphysis It can resist strain and can absorb mechanical shock.

Hyaline cartilage is a type of connective tissue found in areas such as the nose, ears, and trachea of the human body. It can be found at many places including: Nose Just below the thyroid cartilage, as a ring-shaped piece of hyaline cartilage called the cricoid cartilage Feb 25, 2013 - Cartilage types, their location, bone types, classifications and god knows what else More information three types of cartilage hyaline elastic and fibrocartilage Hyaline cartilage is a type of connective tissue which is typically flexible and whitish-blue in color. Fibrocartilage is a transition tissue that should be viewed as a blend between hyaline cartilage and dense fibrous connective tissue. Cartilage: Hyline cartilage, elastic cartilage and fibrous cartilage; Bone: spongy bone and compact bone; 1. Hyaline cartilage is the most prevalent type of cartilage. The word hyaline means “glass-like”, and hyaline cartilage is a glossy, greyish-white tissue with a uniform appearance. Luxury? [1] Hyaline cartilage is pearl-grey in color, with a firm consistency and has a considerable amount of collagen. Hyaline cartilage has very few fibers in its matrix, so the matrix usually looks smooth. *This is the most widespread type of cartilage—other locations include: ends of long bones; cartilages of the nose, larynx, and trachea. Generally, across various articulating surfaces it varies in thickness, going from an average thickness of 2 to 3 mm to 1 to 7 mm in thickness. It is a white, densely arranged, opaque, tufted tissue with a mixture of both chondrocytes and fibroblasts . Hyaline cartilage contains type II collagen fibers and a highly-hydrated ground substance. Hyaline cartilage A higher magnification of the junction of perichondrium with hyaline cartilage is shown in this image. In its fresh state, it is homogeneous and semi-transparent. Fibrocartilage is found in the menisci of the stifle joint, symphyses (e.g., the pelvic symphysis), the annulus fibrosis of the intervertebral discs, and where ligaments and tendons attach to hyaline cartilage surfaces of joints. There are lots of functions of hyaline cartilage according to its location. Fibrous cartilage has the fewest cells so it has the most intercellular space. In fact, fibrocartilage is the strongest cartilage while hyaline cartilage is the weakest cartilage. In histopathological medical usage, a hyaline substance appears glassy and pink after being stained with haematoxylin and eosin—usually it is an acellular, proteinaceous material. Hyaline Cartilage: Hyaline cartilage contains a perichondrium (except the hyaline cartilage at the end of the growing bones). Hyaline cartilage is a simple tissue, with no nerves or blood vessels attached to it. The cells are contained in cavities in the matrix, called cartilage lacunæ. The ends of the bones are covered with hyaline (articular) cartilage that protects the ends of the bones and allows them to glide over each other during movement. Even though it does not have blood supply or nerve communication, it … Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space. Articular cartilage is hyaline cartilage on the articular surfaces of bones,[3] and lies inside the joint cavity of synovial joints, bathed in synovial fluid produced by the synovial membrane, which lines the walls of the cavity. It is also most commonly found in the ribs, nose, larynx, and trachea. Elbow joint. Each lacuna is usually occupied by a single cell, but during mitosis, it may contain two, four, or even eight cells. Hyaline cartilage function. HYALINE CARTILAGE CONNECTIVE TISSUE What does the ground substance resemble? 2.7). Hyaline cartilage is the vital substance lining the bones in your joints. This constitutes the so-called 'capsule' of the space. Fibrocartilage is a transition tissue that should be viewed as a blend between hyaline cartilage and dense fibrous connective tissue. The inter-territorial space between the isogenous cell groups contains relatively more collagen fibres, allowing it to maintain its shape while the actual cells shrink, creating the lacunae. Hyaline cartilage matrix is primarily made of type II collagen and chondroitin sulphate, both of which are also found in elastic cartilage. abundant in collagen fibers hidden in rubbery matrix. Its name derives from its translucent (hyaline) appearance. The exact position at which the chondrogenic layer becomes cartilage proper is difficult to pinpoint, however, … Hyaline cartilage is covered externally by a fibrous membrane known as the perichondrium or, when it's along articulating surfaces, the synovial membrane. Most of the image is occupied by a section of hyaline cartilage and its surrounding connective tissue proper, the … hyaline cartilage. Nucleus. Is a precursor of bone. Location Fibrocartilage: The fibrocartilage occurs in the pubic symphysis, menisci of the stifle joint, and the annulus fibrosis of the intervertebral discs. In its fresh state, it is homogeneous and semi-transparent. Hyaline cartilage provides support and flexibility to different parts of the body. On this website, you can find useful, updated information on specific cartilage-related conditions and possible treatments options, written by world-renowned experts in this field, helpful patient information to read and download, and other useful resources. Epiphyseal (growth plates of long bones)... 2. Greater alar cartilage is a flexible cartilage that forms part of the structure of the nostrils. Location Fibrocartilage: The fibrocartilage occurs in the pubic symphysis, menisci of the stifle joint, and the annulus fibrosis of the intervertebral discs. This membrane contains vessels that provide the cartilage with nutrition through diffusion. I made a cartilage histology ppt for you. Hyaline cartilage 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. Hyaline cartilage is the most common type of cartilage. Hyaline cartilage is found in the nose, ears, trachea, parts of the larynx, and smaller respiratory tubes. Elastic cartilage, which is yellow in appearance, is more pliable… A. Rat, Helly's fluid, Mallory's stain, 612 x. It also forms the temporary embryonic skeleton, which is gradually replaced by bone, and the skeleton of elasmobranch fish. Microscope at 400X: Cartilage cells (chondrocytes) secrete the fibers and ground substance that make up the cartilage matrix. Fibrous cartilage has the fewest cells so it has the most intercellular space. Loss of this cartilage can lead to osteoarthritis. In general, cartilage is a tough, fibrous and blood vessel-free connective tissue that forms flexible linkages (such as in the ribs), supporting structures (such as in the ears and nose), and acts as a shock absorber in joints such as the knee. The hyaline cartilage in the trachea is in the middle of the tracheal wall. Collagen fibers form an imperceptible network Elastic cartilage, which has elastic fibres that make the cartilage more flexible, is found in the ear, part of the nose and the trachea. The extracellular matrix of elastic cartilage contains … Hyaline cartilage has been given its name due to its glossy appearance, and is predominantly made up of collagen, although it displays few collagen fibers. Articular cartilage locations are found throughout the body. Hyaline cartilage found in the knees is bloodless; it receives nutrition from the synovial fluid (joint lubricant) that is normally in the joint. "epiglottis, par of external ear, auditory tubes", B. There are lots of functions of hyaline cartilage according to its location. I made a cartilage histology ppt for you. ... D."fibroblast"] What is the location of this tissue? Lacuna. Ground substance. Deep dissection. The articular cartilage extracellular matrix (ECM) has a highly specialized architecture that is zonally organized: the superficial zone consists mostly of collagen II fibers aligned parallel to the articular surface to resist shear forces, whereas the deep zone consists of the same fibers aligned perpendicularly to the bone interface to absorb compressive loads. It is the most common cartilage and is found on articular surfaces of bone, walls of the respiratory system (trachea and bronchi), and epiphyseal plates. 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.It is a glossy blue-white in appearance and very resilient. « Previous card | Connective main | Next card ».
