What characteristics makes hyaline cartilage unique?

Hyaline cartilage, the most widely distributed form, has a pearl-gray semitranslucent matrix containing randomly oriented collagen fibrils but relatively little elastin. It is normally found on surfaces of joints and in the cartilage making up the fetal skeleton.

What are the characteristics of hyaline cartilage quizlet?

Match
  • Hyaline Cartilage- Structure. Glassy- appearing matrix, lacunae house chondrocytes, usually covered by perichondrium.
  • Hyaline Cartilage- Function. Smooth surfaces for movement at joints model for bone growth.
  • Hyaline Cartilage- Location.

What are functions of hyaline cartilage?

Hyaline cartilage is slippery and smooth which helps your bones move smoothly past each other in your joints. It’s flexible but strong enough to help your joints hold their shape. Hyaline cartilage locations in your body include: At the ends of bones that form joints.

What are the three characteristics of cartilage?

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 or nerves. Some fibrocartilage such as the meniscus of the knee does however have blood supply in part.

What is hyaline cartilage made of?

The matrix of hyaline cartilage is composed of type II collagen, proteoglycans, glycoproteins, and extracellular fluid. The semitranslucent blue-gray matrix of hyaline cartilage contains up to 40% of its dry weight in collagen.

What are the functions of hyaline cartilage quizlet?

Hyaline cartilage is the main type of cartilage found supporting and reinforcing body structures and joints. It covers the ends of long bones in joint cavities, it is found on the ends of the ribs that join the sternum, it supports the trachea, nose and most of the voice box or larynx.

How would you describe the structure of hyaline cartilage quizlet?

What is the structure of hyaline cartilage? It is made up of cells and a cartilage matrix. The matrix is made up of Type II collagen, GAGs, and water. (The GAGs will be the type that are hydrophilic.)

What is found in hyaline cartilage quizlet?

Terms in this set (2)

Hyaline cartilage is the most abundant type of cartilage. Although it contains large amounts of collagen fibers, THEY ARE NOT APPARENT and the matrix appears glassy.

What visual features sets hyaline cartilage apart from other types of cartilage?

What visual feature sets hyaline cartilage apart from other types of cartilage? Matrix appears transparent.

Where is hyaline cartilage found in the body?

Hyaline – most common, found in the ribs, nose, larynx, trachea. Is a precursor of bone. Fibro- is found in invertebral discs, joint capsules, ligaments. Elastic – is found in the external ear, epiglottis and larynx.

What cells are present in hyaline cartilage?

Chondrocytes are the only cartilage cells to be found in hyaline cartilage. These cells start as chondroblasts (or perichondrial cells) which produce the cartilaginous matrix, then get immobilized within it in small spaces called lacunae.

How is hyaline cartilage different from elastic cartilage?

Hyaline cartilage is a translucent white type of cartilage present in areas of the body such as the joints. The main difference between this type of cartilage and elastic cartilage is that elastic cartilage contains many elastic fibers, whilst hyaline cartilage contains a matrix of mainly collagen fibers.

How is hyaline cartilage different from elastic or fibrocartilage?

Hyaline cartilage is easily distinguished from elastic and fibrocartilage because of the homogeneous (no fibers are visible) extracellular matrix (ECM) .

Why is hyaline cartilage smooth?

The cells are called chondrocytes (ch) and the spaces in the cartilage in which they are found are called lacunae. Hyaline cartilage has very few fibers in its matrix, so the matrix usually looks smooth.

Is hyaline cartilage loose or dense?

Hyaline cartilage is flexible, elastic, and surrounded by a dense membrane called perichondrium. Fibrocartilage is the strongest type of cartilage and composed of hyaline and dense collagen fibers. It is inflexible, tough, and located in areas such as between vertebrae, in some joints, and in heart valves.

Why hyaline cartilage is glassy?

The staining of the matrix is variable. Remember that there are abundant type II collagen fibrils in the matrix. However, they are too small to be resolved in the light microscope, so the matrix has an amorphous, glassy (or “hyaline”) appearance.

Does hyaline cartilage have lacunae?

Chondrocytes occupy relatively little of the hyaline cartilage mass. They are embedded in an extensive matrix and are located in matrix cavities known as lacunae, which appear as tiny white lakes under a light microscope.

Is hyaline cartilage avascular?

Hyaline cartilage is avascular and aneural compact tissue with abundant extracellular matrix (1) with collagenous microfibrils. Chondrocytes are present in lacunas as isogenous groups (2).

Is hyaline cartilage dense connective tissue?

Surrounding cartilage is a multicellular layer of flattened cells called the perichondrium. The inner layers possess chondrogenic properties, thereby permitting the appositional growth of cartilage; the outer layer represents a covering of dense fibrous connective tissue (Hyaline Cartilage 2 and Hyaline Cartilage 3).

Where is hyaline cartilage not found?

So, the correct answer is ‘kidney‘

What do you mean by hyaline?

Definition of hyaline (Entry 2 of 2) 1 : something (such as the clear atmosphere) that is transparent. 2 or hyalin \ ˈhī-​ə-​lən \ : any of several translucent nitrogenous substances related to chitin, found especially around cells, and readily stained by eosin.
