What does hyaline cartilage look like under a microscope?
What does hyaline cartilage look like under a microscope?
2.5. 1 Hyaline cartilage. 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.
What is the size of chondrocytes?
High-magnification images of chondrocytes viewed by CLSM, but before thresholding, showed a surprising number of cells (∼40%) with cytoplasmic processes emanating from the cell body (Fig. 2). The processes were typically <1 μm in diameter and of variable length, but in extreme and rare cases were up to 80 μm long.
What shape are chondrocytes in hyaline cartilage?
round
Chondrocytes are important in synthesizing and maintaining components of the ECM. At the periphery, young chondrocytes (or chondroblasts) have an elliptic shape, with their long axis parallel to the surface. At the core, mature chondrocytes have a round shape and often appear as a group of up to eight cells.
Does hyaline cartilage have chondrocytes?
Hyaline cartilage is found in the synovial joints and assists the motion of joints. It is composed of chondrocytes and extracellular matrix.
What is the largest hyaline cartilage?
Hyaline cartilage is the glass-like (hyaline) but translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea….

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.
How big is a cartilage cell?
Results: The mean height of the hyaline articular cartilage layer was found to be 2.4mm, the volume density of chondrocytes therein being 1.65%, the number of cells per mm(3) of tissue 9626 and the mean cell diameter 13 microm.
What type of matrix does hyaline cartilage have?
collagen
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 is the matrix of hyaline cartilage?
Hyaline cartilage matrix is primarily made of type II collagen and chondroitin sulphate, both of which are also found in elastic cartilage. Hyaline cartilage exists on the sternal ends of the ribs, in the larynx, trachea, and bronchi, and on the articulating surfaces of bones.
What is the difference between hyaline and articular cartilage?
Hyaline cartilage provides support and flexibility to different parts of the body. When hyaline cartilage is on the articular surfaces of bones (the surfaces at joints), it is called articular cartilage. Articular cartilage functions as a shock absorber and also reduces friction between bones where they meet at joints.
What is hyaline cartilage classified as?
Hyaline cartilage is a type of connective tissue found in areas such as the nose, ears, and trachea of the human body. The word hyaline means “glass-like”, and hyaline cartilage is a glossy, greyish-white tissue with a uniform appearance.
When a thin slice of hyaline cartilage is examined under the microscope, it is shown to consist of cells (chondrocytes) of a rounded or bluntly angular form, lying in groups of two or more in a granular, or almost homogeneous matrix.
Where are chondrocytes found in the hyaline cartilage?
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. Chondrocytes are important in synthesizing and maintaining components of the ECM.
What is the difference between lacunae and chondrocytes?
Near the hyaline cartilage surface, these chondrocytes are small in size, and the lacunae are elliptical. But in the deep hyaline cartilage structure, the chondrocyte becomes larger and more polyhedral shaped. Lacunae are the oval or elliptical space like cavity in the matrix of hyaline cartilage.
What are the types of lacunae in hyaline cartilage?
These type of multicellular lacunae are also known as cell nest or isogenous cells groups. The extracellular matrix of hyaline cartilage histology is homogenous and glassy in appearance. The amorphous ground substance of a hyaline structure is generally firm and contains a collagen fiber network (type II).
