The Three Types Of Carilage In The Human Body

12. What are the 3 types of cartilage and where would you find each type?

The musculoskeletal system provides support for the body as it provides protection, protecting the body from any possible damage. The limbs of the body, e.g. arms, legs, hips and shoulders help support and keep the body held up. Many other bones support different parts of the body such as the rib cage supports and protects all the organs which are located inside the rib cage, such as the heart, lungs, kidneys and others. The shape of the skeleton allows us to cope with

9. Hyaline cartilage is found on many joint surfaces, it has a very firm consistency. It contains no nerves or blood vessels, and its structure is relatively simple. Elastic cartilage, also called yellow cartilage, is present in the ears; it contains elastic fiber networks and collagen fibers. Fibrocartilage is found in the pubic symphysis, the annulus firbrosus of the intervertebral discs, menisci and the TMJ. During labor, the pubic symphysis is loosened to aid in delivery.

The second type of tissue found in the body is connective tissue. They lie beneath the epithelial tissue helping to connect different part of the internal structure, the cells are more widely separated from each other then in epithelial tissue. The intercellular substance known as the matrix is found in considerably large amounts. Within the matrix there are usually fibres which may be a jelly like consistency or dense and rigid depending on the type, function and positioning of the tissue. Theses fibres form a supporting system for cells to attach to. The major functions of connective tissue are to transport materials, give structural support and protection. The types of connective tissue that will be explained are blood, bone, cartilage, bone, areolar tissue and adipose tissue.

The articular cartilage is a connective tissue that covers the part of the epiphysis where the bone comes together to form a joint, also known as an articulation. Articular cartilage allows bones to glide over each other creating very little friction and also makes it easier for

Hyaline cartilage is the most common kind, and forms fetal skeleton and joint surfaces. It is a strong but flexible tissue that is strengthened by fine collagen fibers (Cartilage Types 04/20/17). Since it exists on joint surfaces, it helps cushion bone interactions and helps bear and distribute weight, thus making it most resistant to wear-and-tear. However, it has poor regenerative properties, and is the weakest of the three types. The second type of cartilage is elastic cartilage, which is more flexible than hyaline cartilage and found in the pinnae, Eustachian tube, larynx, and epiglottis (News Medical Cartilage 04/20/17). The chondrocyte cells in elastic cartilage create a threadlike network of elastic fibers, allowing it to provide strength and elasticity to maintain the structures it makes up. The last type of cartilage is fibrocartilage, which is the strongest out of the three. It is made up of alternating layers of hyaline cartilage matrix in addition to dense collagen fibers fixed in the direction of functional stresses (Cartilage Types 04/20/17). This kind of cartilage is found in between vertebral discs and the pubic

B) The cartilage protects from bones rubbing each other in the joints because if the bones rub against each other can hurt your hip joint.

Articular cartilage is organized into four different layers/zones: superficial (tangential), middle (transitional), deep (radial), and calcified. The cellular structure of each layer is slightly different and corresponds to its role and type of force that it can withstand; the superficial layer has parallel alignment to withstand shear forces, the middle layer begins to resist compressive forces with a more oblique orientation, and the deep layer has a perpendicular alignment that largely resists compression. The calcified layer is where the cartilage connects to bone tissue, and is separated from the deep layer by the tidemark, which is a region of parallel-oriented fibers to reduce shear force. Since grading of chondral lesions (commonly on a Grade 0-4 scale) is based upon the depth of injury, it is important to understand these specialized

4Epithelium tissue can comprise of diverse varieties of tissues. The varieties are cuboidal, squamous and columnar. Squamous epithelium tissue which are pictures 1 and 3, that are available in the alveoli and the throat's layering so as to cover, they are flat and are shaped of cells which. Essentially the columnar epithelium tissue which is picture 2 is likewise comprised of layer but the layers are segment shaped and are available in the pharynx's covering, anus, uterus and

The human skeleton has 6 main functions that provide the body with good health. They are as follows:

The articular cartilage of joints such as the hip and knee suffers both degenerative diseases, such as osteoarthritis, and trauma, for example in sports injuries. A great deal of attention has been paid to the replacement of diseased joints over the last several decades and medical device technology has produced a very effective portfolio of procedures and devices that are expected to give successful replacement of these joints in 90% of patients for at least ten years. It may well be that tissue engineering will enable the regeneration of diseased joints in the future, but this is not seen as either technically feasible nor economically viable as of yet. Of more importance in tissue engineering is the possibility of faster, effective treatment of small lesions arising from sports injuries, where both of these technical difficulties are more easily overcome and the economic equation is

The skeletal system of a grown human is made up of 206 different bones. The bones are attached together by tendons, cartilage, and ligaments. A bone is split into different layers. The outer layer of a bone is very sturdy and solid. The next layer is fairly malleable. The substance in the middle of a bone, is called bone marrow. Bone marrow is where blood cells are constantly being generated. If humans did not have bone marrow in their bones the tissues of the body could not generate ATP (Adenosine triphosphate). ATP is how energy is used and stored away. The skeletal system is very important for everyday functions such as movement, protection of internal organs, and support, which is needed for survival. Without the skeletal system we would

The skeletal system is made up of bones and joints. Bones are a dry dense tissue that is composed of calcium phosphorous and organic matter. The bones are protected and covered by a layer of fibrous connective tissue membrane called the periosteum (Brown, et al., 2015, p. 1547). There are two basic types of bone tissue: Compact Bone and Spongy Bone. Compact bones are dense smooth bones, while Spongy bones are composed of small needle-like pieces of bones and open space. Bones are then categorised according to the shape of the bone into four groups: long, short, flat and irregular. Long bones characteristically are typically longer then they are wide and generally have a shaft with heads at either ends e.g. the humerus. They are mainly compact bones. Short bones

Bone serves the organism at multiple levels: As a system, bones permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing rigid attachment sites for muscles and acting as a system of levers to amplify small movements. As an organ, bones protect the viscera and house the hemopoietic tissue (red marrow). As a tissue, bones serve as a reservoir of readily mobilizable calcium, an
