Hyaline, or articular, cartilage covers the ends of bones to create a low-friction environment and cushion at the joint surface . When cartilage in the joint is healthy, it effectively allows fluid bending/straightening motions and protects the joint against weight-bearing stresses.
What are three functions of cartilage?
- Cartilage gives shape, support, and structure to other body tissues.
- It also helps to cushion joints.
- Cartilage also smoothens the bone surfaces at the joints.
- It is essential for the development and growth of long bones.
What is bone cartilage?
Cartilage (cartilaginous tissue) is a resilient and smooth elastic tissue, rubber-like padding that covers and protects the ends of long bones at the joints and nerves, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components.
What is the function of cartilage and bone class 9?
Bone and cartilage are two specialized forms of connective tissues which are composed of cells embedded within an extracellular matrix. Both bone and cartilage play an important role in protecting the internal organs of our body, providing structural support and surfaces for muscle attachment .
What is cartilage short answer?
Cartilage is a flexible connective tissue found in many parts of the body. ... It can bend a bit, but resists stretching. Its main function is to connect bones together. It is also found in the joints, the rib cage, the ear, the nose, the throat and between the bones of the back.
How does cartilage turn to bone?
Over time, most of this cartilage turns into bone, in a process called ossification . ... Growth occurs when cartilage cells divide and increase in number in these growth plates. These new cartilage cells push older, larger cartilage cells towards the middle of a bone.
What is cartilage Class 5?
Answer: Cartilage is a strong, flexible type of connective tissue found within a body. ... Cartilage is connective tissue that is less rigid than bone and less flexible than muscles. Cartilage structure. Connective tissue is essential for our bodies to function properly.
What is cartilage Byjus?
Cartilage is defined as a type of connective tissue that provides structural support and protection for the body’s joints . It’s made from specialized cells called chondrocytes that produce a combination of collagen, proteoglycans and other non-collagenous proteins.
Which is a function of cartilage quizlet?

Where is your cartilage?
Cartilage is the tough but flexible tissue that covers the ends of your bones at a joint . It also gives shape and support to other parts of your body, such as your ears, nose and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other.
Can cartilage change bone?
The cartilage is not converted to bone , but is gradually replaced by it. The osteoblasts and blood vessels invade the area of degenerating cartilage.
Can cartilage cells turn into bone cells?
However, very recent studies in long bone suggest that chondrocytes can directly transform into bone cells . ... This transformation was initiated at the inferior portion of the condylar cartilage, in contrast to the initial ossification site in long bone, which is in the center.
What are the functions of ligaments and cartilage in a joint?
A ligament is an elastic band of tissue that connects bone to bone and provides stability to the joint . Cartilage is a soft, gel-like padding between bones that protects joints and facilitates movement.
What is the function of cartilage Class 10?
The tracheal cartilages help support the trachea while still allowing it to move and flex during breathing . Rings of cartilage are present in the throat as it helps the throat from collapsing when there is a low amount of air present. It also helps them to expand when food or water passes through it.
What is bone class 9?
Bones: It is also a connective tissue that forms the framework that supports the body . It is a strong and nonflexible tissue. Bone cells are embedded in a hard matrix that is composed of calcium and phosphorus compounds. Ligaments: Two bones are connected to each other by a connective tissue called the ligament.
What are ligaments?
A ligament is a fibrous connective tissue that attaches bone to bone , and usually serves to hold structures together and keep them stable.
What is a joint?
A joint is the part of the body where two or more bones meet to allow movement . Generally speaking, the greater the range of movement, the higher the risk of injury because the strength of the joint is reduced. The six types of freely movable joint include ball and socket, saddle, hinge, condyloid, pivot and gliding.
What is cartilage quizlet?
Cartilage tissue. One of the four classes of connective tissue . It is a firm, flexible tissue that contains no blood vessels or nerves.
What are ligaments Class 9?
A ligament is a fibrous connective tissue that connects bones to other bones . They are elastic with a poor blood supply.
What is the function of the cartilage located in the epiphyseal plates?
Epiphyseal cartilage is hyaline cartilage tissue with a gelatinous texture, and it is responsible for the longitudinal growth of the long bones in birds and mammals . It is located between the epiphysis and the diaphysis. Epiphyseal cartilage also is called a growth plate or physis.
What is the function of chondrocytes quizlet?
Resists compression; cushions and supports body structure . Description – Cartilage cells (chondrocytes) located within spaces (lacunae) in the tissue matrix.
What causes cartilage loss?
Cartilage is a tough, flexible tissue found throughout the body. It covers the surface of joints, acting as a shock absorber and allowing bones to slide over one another. It can become damaged as a result of a sudden injury , such as a sports injury, or gradual wear and tear (osteoarthritis).
Can you be born without cartilage?
The answer is yes and no . Babies are born with pieces of cartilage that will eventually become the bony kneecap, or patella, that adults have. Like bone, cartilage gives structure where it’s needed in the body, such as the nose, ears, and joints. But cartilage is softer and more flexible than bone.
Can cartilage break off in your knee?
Loose body is the term applied to small fragments of articular cartilage that break off in the knee joint as a result of a knee injury or degeneration. Loose bodies float around within the knee joint and cause pain, catching, locking, or swelling depending upon where the fragments migrate.
What is the function of cartilage for movement?
Cartilage is a flexible connective tissue that keeps joint motion fluid by coating the surfaces of the bones in our joints and by cushioning bones against impact .
What are five functions of bones?
The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis . Together, the muscular system and skeletal system are known as the musculoskeletal system.
What is only found in a child’s bone?
Some of a baby’s bones are made entirely of a special material called cartilage (say: KAR-tel-ij). Other bones in a baby are partly made of cartilage. This cartilage is soft and flexible. During childhood, as you are growing, the cartilage grows and is slowly replaced by bone, with help from calcium.
How do cartilage cells survive?
Chondrocytes rely on diffusion to obtain nutrients as, unlike bone, cartilage is avascular, meaning there are no vessels to carry blood to cartilage tissue. This lack of blood supply causes cartilage to heal very slowly compared with bone.
Why is yellow marrow yellow?
The color of yellow marrow is due to the much higher number of fat cells . Both types of bone marrow contain numerous blood vessels and capillaries. At birth, all bone marrow is red. With age, more and more of it is converted to the yellow type.
What’s the difference between joints and cartilage?
Joints are the areas where 2 or more bones meet. ... Joints consist of the following: Cartilage. This is a type of tissue that covers the surface of a bone at a joint.
Why do bones widen with age?
The body naturally removes old bone and replaces it with new bone. When you are young, bone is replaced much more quickly than it is lost. This is when you are building stronger and denser bones. Around age 30, most people reach their peak bone mass.
What are cartilage destroying cells called?
FMA. 66783. Anatomical terms of microanatomy. Chondroblasts, or perichondrial cells , is the name given to mesenchymal progenitor cells in situ which, from endochondral ossification, will form chondrocytes in the growing cartilage matrix. Another name for them is subchondral cortico-spongious progenitors.
How does cartilage grow?
Cartilage can grow in two ways: Interstitial growth – chondrocytes grow and divide and lay down more matrix inside the existing cartilage. ... Appositional growth – new surface layers of matrix are added to the pre-existing matrix by new chondroblasts from the perichondrium.
