which type of cartilage is found in the intervertebral discs?

The hyaline cartilage is found in the nasal septum, trachea, ends of the growing bones, and in between the ribs and the sternum. VII INTERVERTEBRAL DISCS. Intervertebral discs loose their water content with time and become narrower (the explanation behind the loss of height in elderly) as a normal aging process. (nucleus pulposus). Let’s first focus on hyaline cartilage, which is the most common type of cartilage. Fibrocartilage. Intervertebral discs consist of an outer fibrous ring, the annulus fibrosus disci intervertebralis, which surrounds an inner gel-like center, the nucleus pulposus. Fibrocartilage contains even more collagen fibers than hyaline cartilage. Intervertebral discs have a high collagen content together with hydrophilic glycosaminoglycans. Elastic cartilage is springy, yellow, and elastic and is found in the internal support of the external ear and in the epiglottis 3 Where can you find those types of cartilage? The short-chained type X collagen was once thought to be produced exclusively by hypertrophic chondrocytes during endochondral ossification. So, there are three main types of cartilage found within the body. This quality makes it a good connector in high-stress areas of the body, such as between bones and ligaments and tendons. This image is an example of hyaline cartilage on the articulating surface of a long bone, with the articulating surface located at the top of the image. The type of cartilage found in the intervertebral discs is _____ cartilage. The annulus fibrosus consists of several layers (laminae) of fibrocartilage made up of both type I and type II collagen. Elastic Cartilage: Yellow cartilage. Cartilage: The three types of cartilage There are three types of cartilage: Hyaline - most common, found in the ribs, nose, larynx, trachea. ; Elastic - is found in the external ear, epiglottis and larynx. It’s the most rigid type of cartilage and can be found in intervertebral discs in the spine. a. Hyaline cartilage b. Elastic cartilage c. Fibrocartilage d. All of the above e. None of the above. Fibrocartilage provides cushioning between the intervertebral discs. Epiglottis, corniculate, cuneiform and apical part of the arytenoids cartilages of larynx. With a pliable structure composed primarily of water, this tissue type is also extremely tough. The anulus consists of conce … Hyaline cartilage provides more rigidity and strength and is found in the rib cage, immature skeleton, and joint surfaces of the bones. On the other hand, fibrocartilage acts as a mechanical supporting tissue in the intervertebral discs of the spine, the temporomandibular joint (TMJ) of the jaw, and the meniscus of the knee (Palmer and Werner, 1981). Calcification does not occur. Is a precursor of bone. What type of tissue makes up the "Adam's apple"? a. Hyaline cartilage b. Fibrocartilage c. Elastic cartilage d. Both a and b e. Both a and c. 8. … c. Cartilage: 3 types: i. Hyaline cartilage is found on the ends of bones and acts as cushioning in joints. Synovial Joints. The outer layer of tough cartilage supports the stacked vertebrae while the central nucleus provides cushioning. In contrast to other cartilage types, collagen type I is dominant in fibrous cartilage. The outer ring consists of fibrocartilage (type I collagen), while the inner material shows many similarity to the articular hyaline cartilage both in its biochemical (type II collagen) and histological appearance. The first type is called hyaline cartilage. The intervertebral disc is a highly organized matrix laid down by relatively few cells in a specific manner. Expert Answer 100% (1 rating) Fibrous cartilage has the fewest cells so it has the most intercellular space. a. ligamentous b. hyaline c. osseous d. fibrous e. elastic. The outer ring consists of fibrocartilage (type I collagen), while the inner material shows many similarity to the articular hyaline cartilage both in its biochemical (type II collagen) and histological appearance. The fibrocartilage is found in the pubic symphysis, menisci of the stifle joint, and the annulus fibrosis of the intervertebral discs. So, you can find hyaline cartilage in the larynx and trachea in the throat portion of the body, and then also in all of the joints where the surfaces of bones are articulating each other. Which type of cartilage would be punctured if you chose to pierce the auricle of your ear? Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis. Which type of cartilage is found in the intervertebral discs? Cartilage is one of the four types of connective tissue in the body. (nucleus pulposus). in the intervertebral discs and some ligaments. Fibro- is found in invertebral discs, joint capsules, ligaments. types of cartilage are found in the following; articular surfaces of bone, between the intervertebral discs, is involved in endochondral ossification. a) is named because it contains a larger amount of collagen fibres than other types of cartilage. This is similar to hyaline cartilage except that elastic fibres are present instead of type II collagen fibres. Which type of cartilage forms the intervertebral disc? Cartilage is found throughout the human body in areas such as the joints, nose, airway, intervertebral discs of the spine, and the ear. It is associated with dense connective tissue with a gradual transition at the border between the two tissues. Each intervertebral disc has a: Tough outer shell of cartilage, which is known as the annulus fibrosus, and Soft, squishy centre known as the nucleus pulposus. iii. 8. Fibrocartilage is found in the pubic symphysis, the annulus fibrosus of intervertebral discs, menisci, and the temporal mandibular joint. "epiglottis, par of external ear, auditory tubes", B. [ Select ] A. Fibrous cartilage is … Therefore, the damage of this tissue is not common or chronic, as compared to other types of cartilage found in the body. Fibrocartilage is the strongest of the 3 types and found between the vertebrae (intervertebral discs) and knee joints (meniscus). The thyroid cartilage is composed of hyaline cartilage. d. How are their locations linked to their functions? Which type of connective tissue is found between the ribs and sternum, or supporting the trachea? The "Adam's apple" is a nickname for part of the larynx formed by the thyroid cartilage. b) is found in intervertebral discs and the pubic symphysis joint. The central gelatinous nucleus pulposus is contained within the more collagenous anulus fibrosus laterally and the cartilage end plates inferiorly and superiorly. Elastic Cartilage Elastic or yellow cartilage contains elastic fiber networks and collagen fibers. It is extremely slippery and enables the joints to move smoothly. Hyaline cartilage is found in the nose, ears, trachea, parts of the larynx, and smaller respiratory tubes. There are three types of cartilage: hyaline, fibrocartilage, and elastic. Expert Answer The normal human spinal column contains 23 fibrocartilage intervertebral discs (6 cervical, 12 thoracic, and 5 in the lumbar region), each a few millimeters thick, lying between adjacent surfaces of the vertebrae and making up roughly a quarter7to a third4of the height of the column. Under the age of 35 years, the intervertebral discs contain the more flexible collagen types II, IV, and IX, besides the ubiquitous type I collagen (70). This type of cartilage is found in structures such as the meniscus and intervertebral discs. Matrix consists of lacunar capsule containing individual chondrocytes. Wall of the medial part of the auditory tube. Fibrocartilage lacks a perichondriumand, therefore, a synchondrosis is made of hyaline cartilage; symphysis are made of fibrocartilage; Examples of synchondroses include joints between the ribs and sternum. More recently, however, it has been found elsewhere, for example in articular cartilage. Articular cartilages of most synovial joints, Thyroid, cricoid and arytenoid cartilages, pharyngeal cartilages, parts of nasal septum, epiphyseal plate essential for bone growth. It’s also the strongest type of cartilage. A. Hyaline cartilage B. Fibrocartilage C. Reticular cartilage D. Articular cartilage E. Elastic cartilage. It is found in symphysis, Intervertebral discs, public symphysis, articular disc of most of the joints and menisci of knee joint. So this is called articular cartilage. Two main parts of the intervertebral discs are the outer ring (annulus fibrosus) and the inner gelatinous material. Symphyses examples are the joints in the intervertebral discs and the pubic symphysis.

Though it is not strictly part of the usual diarthrodial joints, the structure of the intervertebral discs is shortly presented as its pathology is very common problem. "pubic symphysis, intervertebral discs, menisci, portions of tendons", C."most abundant cartilage in the body; ends of long bones; anterior ends of ribs, nose, parts of the larynx, trachea, bronchi, bronchial tubes, embryonic and fetal skeleton"] What is the function of this tissue? The function of the outer ring would be to keep the inner substance within the disc and resist the rotational and loading forces. is typically found in relation to joints (forming intra-articular lips, discs and menisci) and is the main component of the intervertebral discs. Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space. This is similar to hyaline cartilage except that elastic fibres are present instead of type II collagen fibres. - Answers Elastic Cartilage Elastic or yellow cartilage contains elastic fiber networks and collagen fibers. What type of cartilage is found in the external ear, the pubic symphysis, the intervertebral discs, the surfaces of long bones, the cartilage of the ribs? Fibrocartilage is found in the pubic symphysis, the annulus fibrosus of intervertebral discs, menisci, and the temporal mandibular joint. 9. What type of cartilage is the intervertebral disc? It is found in symphysis, Intervertebral discs, public symphysis, articular disc of most of the joints and menisci of knee joint. Cartilage is a semi-rigid but flexible avascular connective tissue found at various sites within the body. In the present study, the occurrence of type X collagen in the intervertebral disc has been investigated. This study compared the phenotypes of nucleus pulposus (NP), annulus fibrosus (AF) and articular cartilage (AC) cells using rat coccygeal discs and AC from both young and aged animals and a combination of microarray, real-time RT-PCR and immunohistochemistry.
