Elastic cartilage contains, in addition to collagen, fibers of the protein elastin. This makes it firm yet supple, giving support, for example, to the external ear and epiglottis.

Fibrocartilage is made up of tightly packed bundles of collagen fibers, making it resilient and able to withstand compression. Fibrocartilage lies, for example, between vertebrae.

types of bone cancer

Types of bone cancer

Mostly when someone with cancer in the bones this is called metastatic cancer. It can be seen in many types of advanced cancer such as breast cancer, prostate cancer and lung cancer. When these types of cancer in the bones are examined under the microscope, the tissue change observed. For example, if someone has lung cancer that has spread to bones, the cancer cells in bone are still and act as cells of lung cancer. They did not look or behave like cells from bone cancer, even if they are in the bones. Because these cells also act as cancer cells of lung cancer, they still need to be treated with drugs that are used for lung cancer.

cartilage 3 types

Cartilage, unlike other types of connective tissue, has no blood vessels. It is tough but pliant because the ground substance between the cells contains combinations of proteins and sugars. Cartilage is described as hyaline, fibrous or elastic, depending on the density and type of fibers present in its composition. Hyaline, the most abundant type of cartilage, is clear and glassy, with few cells and fibers in the ground substance. Hyaline covers the ends of bones at the joints, and also forms the rings which keep the trachea open. Fibrocartilage is made up of tightly packed bundles of collagen fibers, making it resilient and able to withstand compression. Fibrocartilage lies, for example, between vertebrae. Elastic cartilage contains, in addition to collagen, fibers of the protein elastin. This makes it firm yet supple, giving support, for example, to the external ear and epiglottis.

cartilaginous tissues

Cartilaginous tissues: Hyaline is characterized by:
* perichondrium
* homogeneous matrix
* chondrocytes are prepared individually or in groups.
* the chondrocytes are of a size in between.

The perichondrium has two layers.

cartilages and cartilage structures

Cartilaginous is a kind of tissue which is hyaline, trachea characteristics.
The hyaline cartilage is characterized by:
* perichondrium
* Matrix structure
* Chondrocytes are prepared individually or in groups.
* size of chondrocytes

The perichondrium has two layers: fibrous layer (collagen fibers, fibroblasts) and condrogena layer which is contains condroblasts.

Disease and damage to the cartilage

Disease and damage to the cartilage

When cartilage disorders, there is a deterioration of chondrocytes located between the matrix. There is talk of an unmasking of the cartilage. The surface is rough, which restricts the function of the affected joint, a developing osteoarthritis. Very often, the cartilage disease of the kneecap (patella Chondropathia) the relatively early, even in children, can lead to difficulties. It may be in the chest, on the border between the bony and cartilaginous rib, too bizarre calcifications come, they call the Chondrokalzinose.

Polychondritis (from "poly": Greek = much, "chondr": Greek chondros = cartilage and "ITIS" suffix for inflammatory diseases, in the English language Relapsing Polychondritis): The recurrent Polychondritis is an extremely rare disease with mostly Schubart, sometimes permanently persistent inflammation of the cartilage. Can be involved all the structures or institutions, which consist of cartilage or where cartilaginous elements are present.

The Chondrose is an expression of degenerative changes in the cartilage. When it comes slipped into a vortex Verschmälerung of the intermediate distance of one or more vertebral segments in comparison to the rest without Deckplattensklerosierung the vertebrae. The intermediate eddy amount of space decreases. For block vertebrae is the space between vertebrae repealed. Causally come congenital or acquired disorders (degenerative, inflammatory, operationally) in question. Chondrosen with the participation of the underlying bone is called osteochondrosis. Solve this piece of cartilage from the cartilage Association, will be designated as Osteochondrosis dissecans.

Cartilage structures can also be damaged. Such damage can be done by a variety of causes arise from an unfortunate traps or a sports accident (traumatic), previous knee injury (post traumatic) or wear with time revealed. The quiescence (immobilization) over time can also result in cartilage damage.

An injury to the cartilage, caused by a strain such as jogging, is often discussed but so far can not be demonstrated. Scientific studies show much more of a good adaptation of the human cartilage in chronic stress . For long distance runners shows a recovery of the cartilage structure a few minutes after the end of sporting activity. In recent decades have surgery to repair cartilage in place. The goal of articular cartilage repair treatment is to restore the surface of the hyaline articular cartilage.

Cartilages

Cartilage Free information center for cartilage structure and biology, histology for you. If wanna learn about cartilages , you need some search on google and wikipedia. following wikipedia info already presents to you. Thank you. Cartilages is a type of dense connective tissue. It is composed of collagen fibers and/or elastin fibers, and can supply smooth surfaces for the movement of articulating bones. Cartilage is found in many places in the body including the joints, the rib cage, the ear, the nose, the bronchial tubes and the intervertebral discs. There are three main types of cartilage: elastic, hyaline, and fibrocartilage. see more at wikipedia info.

Why is cartilage important in the human body? AS SUMMARY

The cartilage is a type of dense connective tissue.
It consists of collagen fibers and / or elastin fibres, and the so-called chondrocytes, all of a company gel earth as a substance called the matrix.
The cartilage is avasculaire (no blood vessels) and nutrients are distributed through the matrix. Cartilagine different functions, particularly by providing a framework in which deposits of bones and can be equipped with smooth surfaces available to monitor the movement of articulation of the bones.
The cartilage in many places in the body, including seals assembly, chest, ear, nose, bronchial tubes and spine.
There are essentially three types of cartilage: hyaline, elastic and fibrocartilage. There are three different types of cartilage, each with specific characteristics according to their function. Hyaline cartilage Hyaline cartilage is the richest type of cartilage.
Hyaline The name derives from the Greek word hyalos, glass effect. And 'the matrix or translucent material basic research. E 'avasculaire hyaline cartilage, primarily of type II collagen. Hyaline cartilage lining of the bones is located in the joints (or the articular cartilage, as a rule, Gristle) and is also inside the bones, as a center of ossification, or the growth of bones. In addition hyaline cartilage from most forms of embryonic skeleton.

Cartilagine articular cartilage is a specialization of hyaline cartilage left at the end of long bones and not perichondrium. Cartilagine elastic Cartilagine elastic (also known as yellow cartilage) is located in the auricle of the tubes and varied as the walls of hearing loss (eustachian) tubes and larynx, and particularly in the epiglottis. The cartilage is to open the tubes. Cartilagine elastic is similar hyaline cartilage elastic, but contains packages (elastin), in the matrix. This follows a rigid structure, which is still elastic.

Cartilagine fibrous Fibrose cartilage (also known as cartilage and white) is a special type of cartilage in the difficult support, or a great force, such as the vertebral column, the public and other symphyses, and on the page or the connection tendons, ligaments to the bone. Rarely is clear dividing line between the neighbours and fibrocartilage hyaline cartilage and connective tissue. The fibrocartilage found in the spinal column contains more collagen hyaline. In addition to type II collagen found in hyaline cartilage and elastic, fibrocartilage contains collagen type I, not on the form fibrés light under the microscope.

Fibrose cartilage seems to be missing, a perichondrium, because it can not be because of collagen type I. If hyaline cartilage at the end of long bones like the femur is damaged, is often replaced by fibrocartilage not reduce the weight of forces and

B. Elastic Cartilage:

ØElastic cartilage is yellowish when fresh. It is more Rexible than hyaline cartilage .

Ø1. Composition and organization. Elastic cartilage is structurally identical to hyaline cartilage except that it contains, in addition to type II collagen fibers, a dense network of branching and anastomosing elastic fibers. This network is densest at the core of the cartilage mass and when stained with elastic stains tee, Verhoeff's or Weigert's), may obscure the organization of the tissue. The chondrocytes characteristically occur in isogenous groups. A perichondrium surrounds the elastic cartilage mass.

Ø2. Histogenesis and growth, Elastic cartilage develops from a primitive connective tissue containing wavy bundles of fibrils that differ in protein composition from both elastin and collagen. Fibroblasts eventually secrete elastin, and the fiber bundles are transformed into branching elastic fibers by an unknown mechanism. The development of chondrocytes and production of the other matrix materials is the same as in hyaline cartilage. Further growth resembles that of hyaline cartilage. 3. Function and location. Elastic cartilage provides flexible support. It occurs alone and with hyaline cartilage; the two may grade into each other in a single cartilage mass. In humans, elastic cartilage is found in the auricle of the external ear, the walls of the external auditory canals and auditory tubes, the epiglonis, and the corniculate and cuneiform cartilages of the larynx.

Hyaline Cartilage

5. Repair. Repair of cartilage fractures involves invasion of the breach by mesenchymal stem cells from the perichondrium, which then differentiate into chondrocytes. If the gap is large. a dense connective tissue scar may form.


6. Function and location. Its ability to grow rapidly while maintaining its rigidity makes hyaline cartilage an ideal fetal skeletal tissue. As fetal cartilage is replaced by bone, hyaline cartilage remains in the epiphyseal plates at the ends of lone: bones, allowing these bones to lengthen between birth and adulthood. At all ages, hyaline cartilage without a perichondrium (articular cartilage) covers the articular surfaces of bone, where its resistance to compression and its smooth texture make it a good cushion and low-friction surface. Hyaline cartilage is the most abundant and widely distributed cartilage type in the body. The costal (rib) cartilages, most of the laryngeal cartilages, the cartilaginous rings supporting the trachea, and the irregular cartilage plates in the walls of the bronchi are hyaline cartilage.

GENERAL FEATURES OF CARTILAGE

Cartilage is a skeletal connective tissue characterized by firmness and resiliency. It forms most of the fetal skeleton and persists in sites where its mechanical properties are needed
Most fetal cartilage eventually becomes bone.
A. Composition: Like all connective tissues, cartilage is composed of cells, fibers, and ground substance. The extracellular matrix predominates and determines cartilage's mechanical properties. Type II collagen is a characteristic cartilage matrix component, and the abundant ground substance is firm and gellike. Cartilage cells are termed chondrocytes.
B. Vascular Supply: Most cartilage is enveloped by a layer of dense connective tissue, the perichondrium, which contains the vascular supply and tibroblastlike stem cells from which additional chondrocytes may arise. Few blood vessels (or nerves) are found within cartilage; thus the composition of the ground substance is crucial to the percolation of nutrients and oxygen to chondrocytes from the surrounding vessels.
C. Cells: Under the light microscope, chondrocytes appear rounded, with an eccentric nucleus, a prominent nucleolus, and basophilic cytoplasm. With EM, chondrocyte surfaces exhibit charac teristic projections and infoldings. The RER and Golgi complex are well developed; the Golgi complex enlarges as the cell grows, and its cisternae fill with secretory material. Some lipid droplets are typically found in the cytoplasm.

Chondrocytes synthesize and secrete the fibers and ground substance of the extracellular matrix: collagen is synthesized on the RER, and GAGs are assembled and sulfated in the Golgi complex.
Because of their meager oxygen supply, chondrocytes produce much of their energy by anaerobic glycolysis
