How does fibrocartilage get nutrients without perichondrium?

How does fibrocartilage get nutrients without perichondrium?

Instead, cartilage relies on two different sources. Synovial Fluid – this is found in joints and supplies nutrients to surrounding chondrocytes (cartilage cells) through diffusion. This is how articular cartilage (the cartilage in bones) receive nutrients, as they don’t have a perichondrium.

Which type of cartilage has a perichondrium?

Elastic cartilage
Elastic cartilage provides strength, and elasticity, and maintains the shape of certain structure such as the external ear. It has a perichondrium.

Why perichondrium is chondrogenic?

The perichondrium consists of an outer fibrous layer that contains fibroblasts and an inner chondrogenic layer that contains chondroblasts. The main functions of the perichondrium are to protect bones from injury and damage, nourish cartilage through blood vessels, and facilitate cartilage growth.

What is the importance of the perichondrium that surrounds cartilage?

What is the importance of the perichondrium that surrounds cartilage? It functions in growth and repair of cartilage. It resists outward expansion when cartilage is subjected to pressure. During intramembranous ossification, which of the listed types of tissue is replaced by bone?

What makes the fibrocartilage an ideal covering for the articular surfaces of the TMJ rather than with a hyaline cartilage?

Fibrocartilage is better able to withstand sheer forces than hyaline cartilage can, which makes it a superior material for enduring the large amount of occlusal load that is placed on the TMJ.

What is the perichondrium and why is it important?

Perichondrium tissue helps protect bones from injury, specifically those still growing or developing. The fibrous nature of perichondrium tissue allows blood flow to easily pass through your body. This steady blood flow helps distribute nutrients necessary to strengthen and nourish your cartilage.

Which surface is not covered by periosteum?

The periosteum is a membranous tissue that covers the surfaces of your bones. The only areas it doesn’t cover are those surrounded by cartilage and where tendons and ligaments attach to bone.

Is the perichondrium in hyaline or elastic cartilage?

Hyaline and elastic cartilage are surrounded by a connective tissue capsule called the PERICHONDRIUM that contains the capillaries from which the nutrients diffuse into the cartilage matrix. Articular hyaline cartilage and fibrocartilage do not have a perichondrium. More information on cartilage: Copyright R. Nims & S.C. Kempf 12/2000

Where does fibrocartilage occur in the human body?

Fibrocartilage does not contain a perichondrium. 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.

What is the difference between hyaline and fibrocartilage cartilage?

The hyaline cartilage is found in the nasal septum, trachea, ends of the growing bones, and in between the ribs and the sternum. The main difference between fibrocartilage and hyaline cartilage is that fibrocartilage is stiff and contains many collagen fibers whereas hyaline cartilage is a soft cartilage that contains fewer fibers.

What causes cartilage cells to be pushed apart?

The matrix secretion will cause the chondroblasts to be pushed apart. As this occurs, the cartilage cells will undergo divisions. This will result in small clusters of chondroblasts within the developing matrix which will also start to secrete matrix and be pushed away from each other.
