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. The central gelatinous nucleus pulposus is contained within the more collagenous anulus fibrosus laterally and the cartilage end plates inferiorly and superiorly. Wall of the medial part of the auditory tube. Cartilage is one of the four types of connective tissue in the body. Two main parts of the intervertebral discs are the outer ring (annulus fibrosus) and the inner gelatinous material. It’s the most rigid type of cartilage and can be found in intervertebral discs in the spine. (nucleus pulposus). It is extremely slippery and enables the joints to move smoothly. Matrix consists of lacunar capsule containing individual chondrocytes. Elastic cartilage makes up body parts such as the ears. Which type of cartilage forms the intervertebral disc? ; Elastic - is found in the external ear, epiglottis and larynx. 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. synchondrosis is made of hyaline cartilage; symphysis are made of fibrocartilage; Examples of synchondroses include joints between the ribs and sternum. Which type of cartilage forms the intervertebral disc? The outer layer of tough cartilage supports the stacked vertebrae while the central nucleus provides cushioning. 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. Cartilage: The three types of cartilage There are three types of cartilage: Hyaline - most common, found in the ribs, nose, larynx, trachea. Which type of connective tissue is found between the ribs and sternum, or supporting the trachea? In the present study, the occurrence of type X collagen in the intervertebral disc has been investigated. How are their locations linked to their functions? 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. [ Select ] A. Elastic Cartilage: Yellow cartilage. 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. A. Hyaline cartilage B. Fibrocartilage C. Reticular cartilage D. Articular cartilage E. Elastic cartilage. Expert Answer 100% (1 rating) It serves as a transitional cartilage. Fibrocartilage. (nucleus pulposus). "epiglottis, par of external ear, auditory tubes", B. … in the intervertebral discs and some ligaments. Fibro- is found in invertebral discs, joint capsules, ligaments. c. Cartilage: 3 types: i. Hyaline cartilage is found on the ends of bones and acts as cushioning in joints. Solution for Elastic cartilage can be found in (a) the pubic symphysis, (b) the external ear, (c) intervertebral discs, (d) the menisci of the knee, (e) the… 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. - Answers The type of cartilage found in the intervertebral discs is _____ cartilage. ii. Therefore, the damage of this tissue is not common or chronic, as compared to other types of cartilage found in the body. More recently, however, it has been found elsewhere, for example in articular cartilage. Is a precursor of bone. Two main parts of the intervertebral discs are the outer ring (annulus fibrosus) and the inner gelatinous material. 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). Synovial Joints. Hyaline cartilage provides more rigidity and strength and is found in the rib cage, immature skeleton, and joint surfaces of the bones. 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? Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis. types of cartilage are found in the following; articular surfaces of bone, between the intervertebral discs, is involved in endochondral ossification. a. Hyaline cartilage b. Fibrocartilage c. Elastic cartilage d. Both a and b e. Both a and c. 8. The function of the outer ring would be to keep the inner substance within the disc and resist the rotational and loading forces. It is found in symphysis, Intervertebral discs, public symphysis, articular disc of most of the joints and menisci of knee joint. The fibrocartilage is found in the pubic symphysis, menisci of the stifle joint, and the annulus fibrosis of the intervertebral discs. It is found in symphysis, Intervertebral discs, public symphysis, articular disc of most of the joints and menisci of knee joint. Fibrocartilage is found in the pubic symphysis, the annulus fibrosus of intervertebral discs, menisci, and the temporal mandibular joint. Symphyses examples are the joints in the intervertebral discs and the pubic symphysis. Elastic Cartilage Elastic or yellow cartilage contains elastic fiber networks and collagen fibers. 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). The second type of cartilage is fibrocartilage. It’s also the strongest type of cartilage. Epiglottis, corniculate, cuneiform and apical part of the arytenoids cartilages of larynx. So this is called articular cartilage. Describe each type of cartilage. iii. The short-chained type X collagen was once thought to be produced exclusively by hypertrophic chondrocytes during endochondral ossification. Calcification does not occur. Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space. Expert Answer In contrast to other cartilage types, collagen type I is dominant in fibrous cartilage. Fibrocartilage is the strongest of the 3 types and found between the vertebrae (intervertebral discs) and knee joints (meniscus). VII INTERVERTEBRAL DISCS. Which type of cartilage would be punctured if you chose to pierce the auricle of your ear? The intervertebral disc is a highly organized matrix laid down by relatively few cells in a specific manner. a. Hyaline cartilage b. Elastic cartilage c. Fibrocartilage d. All of the above e. None of the above. 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 annulus fibrosus consists of several layers (laminae) of fibrocartilage made up of both type I and type II collagen. Fibrocartilage lacks a perichondriumand, therefore, a This type of cartilage is found in structures such as the meniscus and intervertebral discs. Fibrocartilage provides cushioning between the intervertebral discs. Cartilage is found throughout the human body in areas such as the joints, nose, airway, intervertebral discs of the spine, and the ear. Elastic Cartilage Elastic or yellow cartilage contains elastic fiber networks and collagen fibers. What type of tissue makes up the "Adam's apple"? The "Adam's apple" is a nickname for part of the larynx formed by the thyroid cartilage. The thyroid cartilage is composed of hyaline cartilage. The inner material functions as shock absorber for axial loads. a) is named because it contains a larger amount of collagen fibres than other types of cartilage. This quality makes it a good connector in high-stress areas of the body, such as between bones and ligaments and tendons. With a pliable structure composed primarily of water, this tissue type is also extremely tough. Let’s first focus on hyaline cartilage, which is the most common type of cartilage. is typically found in relation to joints (forming intra-articular lips, discs and menisci) and is the main component of the intervertebral discs.

Articular cartilages of most synovial joints, Thyroid, cricoid and arytenoid cartilages, pharyngeal cartilages, parts of nasal septum, epiphyseal plate essential for bone growth. It is found … This is similar to hyaline cartilage except that elastic fibres are present instead of type II collagen fibres. b) is found in intervertebral discs and the pubic symphysis joint. 9. Intervertebral discs have a high collagen content together with hydrophilic glycosaminoglycans. Fibrous cartilage is … This is similar to hyaline cartilage except that elastic fibres are present instead of type II collagen fibres. What type of cartilage is the intervertebral disc? Cartilage is a semi-rigid but flexible avascular connective tissue found at various sites within the body. "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? 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. Fibrous cartilage has the fewest cells so it has the most intercellular space. d. Fibrocartilage is found in the pubic symphysis, the annulus fibrosus of intervertebral discs, menisci, and the temporal mandibular joint. 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? Hyaline cartilage is found in the nose, ears, trachea, parts of the larynx, and smaller respiratory tubes.
