Why does an injury to cartilage heal much more slowly?
Why does an injury to cartilage, especially hyaline cartilage, heal much more slowly than a bone fracture? A layer of dense irregular connective tissue covers cartilage.
Why is fibrocartilage so tough?
Fibrocartilage is tough because it has thick bundles of collagen fibers dispersed through its matrix. Menisci in the knee joint and the intervertebral discs are examples of fibrocartilage. Elastic cartilage contains elastic fibers as well as collagen and proteoglycans.
What is the difference between cartilage and bone tissue?
Bone is a highly vascularized tissue. Unlike cartilage, bone tissue can recover from injuries in a relatively short time. Cancellous bone looks like a sponge under the microscope and contains empty spaces between trabeculae, or arches of bone proper.
What is an example of fibrocartilage?
A plate of hyaline cartilage at the ends of bone allows continued growth until adulthood. Fibrocartilage is tough because it has thick bundles of collagen fibers dispersed through its matrix. Menisci in the knee joint and the intervertebral discs are examples of fibrocartilage.
Does cartilage take longer to heal than bone?
There is a myth that cartilage injuries, like a tear, do not ever heal or grow back. The truth is that it can heal, but it's staggeringly more difficult — and significantly slower — to heal a cartilage injury than a muscle or bone injury. Seeking treatment when you suspect a cartilage tear or injury is important.
Why do bone injuries heal much more rapidly than injuries to cartilage quizlet?
Why do bone injuries heal much more rapidly than injuries to cartilage? Bones are much more well vascularized than cartilage so blood cells are able to carry in nutrients and facilitate healing.
Why does an injury to cartilage especially hyaline cartilage heal much more slowly than a bone fracture quizlet?
Injuries to cartilage heal very slowly because cells and nutrients needed for repair diffuse slowly to the injury site.
Why do bones heal better than cartilage?
Explanation: The reason that bone injuries heal faster than cartilage injuries is because of the ability of bone cells to respond to injuries and start dividing to repair the injury.
Why do bone injuries heal quickly?
"After breaking a bone, your body isolates the fracture site so that it's protected, and floods the area with the nutrients that promote healing," explains Dr. Dewan. "As healing progresses, your body begins to lay down new bone at the fracture site. This new bone hardens over the next several weeks.
Why does cartilage heal slowly?
The lack of active blood flow is the major reason any injury to cartilage takes a long time to heal. Cartilage has no nerve innervation, and hence there is no sensation when it is injured or damaged. When there is calcification of cartilage, the chondrocytes die.
Why does an injury to cartilage especially hyaline?
Answer and Explanation: An injury to hyaline cartilage heals much more slowly than bone because it is devoid of blood vessels. Sufficient blood supply is necessary to support the repair and replication of chondrocytes for cartilage to heal.
Which of these two connective tissues hyaline cartilage or bone osseous would you expect to heal more quickly if injured explain why quizlet?
which of these two connective tissues, hyaline cartilage or bone (osseous), would you expect to heal more quickly if injured? bone - bone cells have the ability to respond to injury and reproduce; cartilage hardly divide after growth is complete.
Why does cartilage heal slowly quizlet?
Why does damaged cartilage heal slowly? Cartilage is avascular, so nutrients and other molecules must diffuse to the site of injury.
Why does injured cartilage take a long time to heal quizlet?
It takes damaged cartilage so long to heal because there are no blood vessels in the inner perichondrium and therefore all of the nutrients and blood have to diffuse across the membrane which takes a longer time to get to the site.
What are the functions of cartilage?
Cartilage is a strong, flexible connective tissue that protects your joints and bones. It acts as a shock absorber throughout your body. Cartilage at the end of your bones reduces friction and prevents them from rubbing together when you use your joints.
What are the characteristics of hyaline cartilage quizlet?
surrounded by perichondrium - nourishes (except for articular surfaces)chondrocytes surrounded by territorial and interterritorial matrices containing type II collagen.homogenous, amorphous matrix.gross: white and translucent, firm and gel-like.forms temporary skeleton in the embryo and epiphyseal plates.
Which type of connective tissue connects bones together and withstands a lot of stress?
4.3 Ligaments connect bones together and withstand a lot of stress. What type of connective tissue should you expect ligaments to contain?
Why are cells not efficient in the elderly?
Because of alterations in cell membranes, transport of oxygen and nutrients into the cell and removal of carbon dioxide and waste products are not as efficient in the elderly. Cells lose their ability to function, or they begin to function abnormally, leading to disease and cancer. Upgrade to remove ads.
What is skeletal muscle composed of?
4.4 Skeletal muscle is composed of very hard working cells. Which organelles do you expect to find in abundance in skeletal muscle cell?
Which type of connective tissue has more collagen fibers?
Dense connective tissue contains more collagen fibers than does loose connective tissue. As a consequence, it displays greater resistance to stretching. There are two major categories of dense connective tissue: regular and irregular. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers in addition to collagen fibers, which allows the ligament to return to its original length after stretching. The ligaments in the vocal folds and between the vertebrae in the vertebral column are elastic.
What are the functions of connective tissue?
Connective tissues perform many functions in the body, but most importantly, they support and connect other tissues; from the connective tissue sheath that surrounds muscle cells, to the tendons that attach muscles to bones, and to the skeleton that supports the positions of the body . Protection is another major function of connective tissue, in the form of fibrous capsules and bones that protect delicate organs and, of course, the skeletal system. Specialized cells in connective tissue defend the body from microorganisms that enter the body. Transport of fluid, nutrients, waste, and chemical messengers is ensured by specialized fluid connective tissues, such as blood and lymph. Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body.
How many questions are there in the connective tissue quiz?
Visit this link to test your connective tissue knowledge with this 10-question quiz. Can you name the 10 tissue types shown in the histology slides?
Which two types of connective tissue are important for maintaining posture?
Two major forms of supportive connective tissue, cartilage and bone , allow the body to maintain its posture and protect internal organs.
Can you get tendinitis from repetitive motion?
Although repetitive motions are unavoidable in many activities and may lead to tendinitis, precautions can be taken that can lessen the probability of developing tendinitis. For active individuals, stretches before exercising and cross training or changing exercises are recommended. For the passionate athlete, it may be time to take some lessons to improve technique. All of the preventive measures aim to increase the strength of the tendon and decrease the stress put on it. With proper rest and managed care, you will be back on the court to hit that slice-spin serve over the net.
Can you tear a tendon?
In all cases, overuse of the joint causes a microtrauma that initiates the inflammatory response. Tendinitis is routinely diagnosed through a clinical examination. In case of severe pain, X-rays can be examined to rule out the possibility of a bone injury. Severe cases of tendinitis can even tear loose a tendon. Surgical repair of a tendon is painful. Connective tissue in the tendon does not have abundant blood supply and heals slowly.
