Score: 4.7/5 (55 votes)
Articular cartilage is hyaline cartilage and is 2 to 4 mm thick. Unlike most tissues, articular cartilage does not have blood vessels, nerves, or lymphatics. It is composed of a dense extracellular matrix (ECM) with a sparse distribution of highly specialized cells called chondrocytes.
Is articular cartilage An example of hyaline cartilage?
Articular cartilage is a type of hyaline cartilage. It is different from usual hyaline cartilage as it has flattened chondrocytes near the surface. In humans, it is 2 to 4 mm thick. It does not have blood vessels, nerves, or lymphatics.
What is another name for articular cartilage?
arthrodial cartilage (articular cartilage) that lining the articular surfaces of synovial joints.
What is the articular cartilage?
Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction. Articular cartilage can be damaged by injury or normal wear and tear.
What is hyaline articular cartilage?
Articular cartilage is hyaline cartilage on the articular surfaces of bones, 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.
Types of Cartilage | Hyaline, Elastic, and Fibrocartilage
How is hyaline cartilage different from elastic cartilage or fibrocartilage?
Hyaline cartilage is easily distinguished from elastic and fibrocartilage because of the homogeneous (no fibers are visible) extracellular matrix (ECM) . ... Elastic cartilage (like hyaline cartilage) has chondrocytes located in lacunae and the tissue is surrounded by a perichondrium .
Is articular cartilage elastic?
The structure and organization of collagens and proteoglycans in articular cartilage have been studied extensively, but the existence of an elastic network has been ignored until very recently, mainly because a small number of earlier histochemical studies reported that little elastin was present in articular cartilage ...
How do you identify hyaline cartilage?
Hyaline cartilage. Cartilage is easy to recognize because it looks so much different from other tissues. This image shows a section of the wall of the trachea. You can feel the hyaline cartilage in your own trachea by pressing you fingers gently against the front of your throat and moving them slightly up and down.
Is articular cartilage the same as meniscus?
Articular cartilage forms the smooth layer of the joint that covers the ends of bones. A layer of this cartilage covers the end of the thigh bone, the top of the shin bone, and the back of the kneecap. The meniscus is a different type of cartilage. This type acts as a shock absorber between bones.
How does articular cartilage differ from other cartilage in the body?
How do articular cartilages differ from other cartilages in the body? Articular cartilages cover articulating surfaces of bones. They resemble hyaline cartilages elsewhere in the body, but they have no perichondrium, and the matrix contains more water than other cartilages have.
What joints have hyaline cartilage?
Hyaline cartilage is found in the synovial joints and assists the motion of joints. It is composed of chondrocytes and extracellular matrix. Chondrocytes plays a major role in the organization of extracellular matrix, which is responsible for the biomechanical properties of cartilage tissue.
What type of cell is hyaline cartilage?
The main cell types in cartilage are chondrocytes, the ground substance is chondroitin sulfate, and the fibrous sheath is called perichondrium.
Which of the following is found in hyaline cartilage?
Hyaline cartilage, the most common type of cartilage, is composed of type II collagen and chondromucoprotein and often has a glassy appearance. Note the numerous chondrocytes in this image, each located within lacunae and surrounded by the cartilage they have produced.
What replaces hyaline cartilage?
Endochondral ossification involves the replacement of hyaline cartilage with bony tissue. Most of the bones of the skeleton are formed in this manner. These bones are called endochondral bones. In this process, the future bones are first formed as hyaline cartilage models.
What is elastic cartilage?
Elastic cartilage is a structural cartilaginous tissue for non-load-bearing body parts, such as ears, nose, and epiglottis (Hutmacher et al., 2003).
Where is hyaline cartilage tissue?
Hyaline cartilage is the most widespread and is the type that makes up the embryonic skeleton. 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…
Is meniscus hyaline cartilage?
Unlike hyaline cartilage, meniscus cartilage has both bony attachments to the tibia and attachments to the surrounding joint capsule. The meniscus cartilage itself is made up of a softer fibrocartilage. The knee has two C-shaped meniscus structures made of a softer fibrocartilage.
What is the difference between articular cartilage and the meniscus quizlet?
Articular cartilage is the tough but smooth covering on the end of bones in most joints. It allows gliding without much resistance and works with the meniscus to cushion the ends of the bone. The meniscus is located between the femur and the tibia.
What type of cartilage is articular cartilage?
Articular cartilage is hyaline cartilage and is 2 to 4 mm thick. Unlike most tissues, articular cartilage does not have blood vessels, nerves, or lymphatics. It is composed of a dense extracellular matrix (ECM) with a sparse distribution of highly specialized cells called chondrocytes.
Why does articular cartilage not have Perichondrium?
Cartilage is devoid of blood vessels. Thus the nutrition of cells within the cartilage matrix is dependent on the diffusion of nutrients from blood capillaries in the perchondrium and/or adjacent tissues through the matrix. ... Articular hyaline cartilage and fibrocartilage do not have a perichondrium.
How is articular cartilage formed?
Cartilage is formed from the mesoderm germ layer by the process known as chondrogenesis. Mesenchyme differentiates into chondroblasts which are the cells that secrete the major components of the extracellular matrix. The most important of these components for cartilage formation being aggrecan and type II collagen.
What are the three types of cartilage and how do they differ?
Cartilage is classified in three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in relative amounts of collagen and proteoglycan. Cartilage does not contain blood vessels (it is avascular) or nerves (it is aneural).
Why is hyaline cartilage glassy?
This type of cartilage has a glassy appearance when fresh, hence its name, as hyalos is greek for glassy. ... Hyaline cartilage has widely dispersed fine collagen fibres (type II), which strengthen it. The collagen fibres are hard to see in sections.
Which type of tissue has an extracellular matrix?
Connective tissue is the most abundant and widely distributed of the primary tissues. Connective tissue has three main components: cells, fibers, and ground substance. Together the ground substance and fibers make up the extracellular matrix.
