Hyaline cartilage is found around the bones of free-moving joints. This is known as articular cartilage. Another example of hyaline cartilage is the tissue found in the walls of the respiratory tract. This includes the bronchi, the nose, the rings of the trachea, and the tips of the ribs.
What type of cartilage is found in the nose?
hyaline cartilageHuman nasal cartilage is hyaline cartilage, although the function and loads placed on it are different depending on the location. We hypothesized that important differences exist between the nasal septal cartilage and lower lateral cartilage (LLC) ultrastructures.
What is the difference between elastic and hyaline cartilage?
Hyaline cartilage is a translucent white type of cartilage present in areas of the body such as the joints. The main difference between this type of cartilage and elastic cartilage is that elastic cartilage contains many elastic fibers, whilst hyaline cartilage contains a matrix of mainly collagen fibers.
What are the 3 functions of cartilage?
Cartilage has many functions, including the ability to resist compressive forces, enhance bone resilience, and provide support on bony areas where there is a need for flexibility. The primary cell that makes cartilage is the chondrocyte, which resides within the lacunae.
Is cartilage a type of bone?
It is a firm tissue but is softer and much more flexible than bone. Cartilage is a connective tissue found in many areas of the body including: Joints between bones e.g. the elbows, knees and ankles. Ends of the ribs.

Where is the cartilage found in the body?
Elastic. Elastic cartilage is found in the ear and epiglottis (located in the throat) as well as parts of the nose and trachea. This cartilage serves to provide strength and elasticity to organs and body structures, such as the outer ear.
What is cartilage in the body?
What is cartilage? Cartilage is a type of connective tissue found in the body. When an embryo is developing, cartilage is the precursor to bone. Some cartilage remains and is dispersed throughout the body, especially to cover the joints. Cartilage also composes most of the outer ear. Cartilage is a unique tissue type because it doesn’t have blood ...
What is the strongest cartilage?
Fibro or fibrous. Fibro cartilage is found in special pads known as menisci and in the disks between your spinal bones, known as vertebrae. These pads are vital to reducing friction in joints, such as the knee. Doctors consider it the strongest of the three cartilage types. It has thick layers of strong collagen fibers.
How to heal cartilage?
Examples include trying to use stem cells to grow into healthy cartilage and attempting to create a microgel like the matrix that nourishes cartilage.
How to stop cartilage breakdown?
Steps like maintaining a healthy weight, practicing flexibility and strength-training exercises, and avoiding overtraining may help to reduce the rate at which cartilage breaks down.
Why does my knee rub against my bone?
Factors such as injury, overuse, poor alignment, or muscle weakness can all lead to the condition. Chondromalacia can cause bone to rub against bone, which is very painful.
Which cartilage is the weakest?
Hyaline cartilage appears slightly glassy under a microscope. This cartilage type has many thin collagen fibers that help to give it strength. However, hyaline cartilage is considered the weakest of the three cartilage types.

Examples of tubes include the cricoid cartilage and carina of the trachea, the torus tubarius at the opening of the auditory tube, and the auricle/pinna of the ear.
What is the articular cartilage of the elbow?
Articular cartilage of the elbow (sagittal view) The function of articular cartilage is dependent on the molecular composition of the extracellular matrix (ECM), which consists mainly of proteoglycans and collagen.
Why is cartilage so slow to repair?
Moreover, cartilage has a very slow turnover and is difficult to repair due to the fact that cartilage tissue is avascular (and also aneural ). Its growth is not usually quantified by an increase in size or mass of the cartilage itself, but instead by its biomechanical properties. Chondrocytes (histological slide)
What are the cells that make up the cartilage matrix?
The chondroblasts that are caught in the matrix are called chondrocytes, and are the main type of specialized cells found in cartilage. Chondrocytes are responsible for producing large quantities of collagenous extracellular matrix and ground substance that is rich in proteoglycans and elastin fibers.
Why does cartilage breakdown occur?
Damage or injury can also happen through pathologic states, where ossification or breakdown of cartilage occurs due to dysfunction of cartilage-specific cells or synovial cells, or imbalances in the microenvironment surrounding the cartilage . Cartilage has limited reparative capacities for a number of reasons:
How does ECM affect cartilage?
Therefore, when this ECM is affected, it can lead to damage or injury. This can happen through physical mechanical forces, where excessive friction and applied forces wear down the cartilage (e.g. due to overuse or traumatic injury during athletics). Damage or injury can also happen through pathologic states, where ossification or breakdown of cartilage occurs due to dysfunction of cartilage-specific cells or synovial cells, or imbalances in the microenvironment surrounding the cartilage.
What is the most common form of cartilage?
The most common form of cartilage is hyaline cartilage. Hyalos is the Greek word for glass, which describes the appearance of this type of connective tissue – translucent, blueish-white, and shiny. Hyaline cartilage is usually only 2 – 4 mm thick (all cartilage must be thin, as there is no vascularization in this tissue type, ...
How many types of cartilage are there?
Types of Cartilage. There are three cartilage types in the human body. Although their components are very similar, the quantities of each component differ, providing different qualities to each type. Accordingly, each type has a particular location.
What are the main components of cartilage?
The Main Ingredients of Cartilage. Cartilage is made up of highly specialized cells called chondrocytes and chondroblasts (chondro refers to cartilage), and other extracellular material which forms the cartilage matrix. All connective tissue types within the human body are derived from the embryonal mesoderm.
Why does cartilage grow slowly in older people?
Because of this, there is little metabolic activity, and little to no new growth in cartilage tissue – one of the reasons the elderly commonly suffer from degenerative joint pain. Cartilage does continue to grow slowly, however. This can be seen in the larger ears and noses of older individuals.
What is the role of elastic cartilage?
Elastic cartilage’s role is purely structural, offering flexibility and resilience due to a mixture of elastic fibers and type II collagen fibers. It is yellow in color, and without the organized structure of fibrocartilage when viewed on a microscope slide. Types of Cartilage.
Which type of growth produces more matrix?
In interstitial growth, chondrocytes proliferate and divide, producing more matrix inside existing cartilage throughout childhood and adolescence. In appositional growth, fresh layers of matrix are added to existing matrix surface by chondroblasts in the perichondrium. The perichondrium is a dense layer of connective tissue which surrounds most ...
What is the role of cartilage in the body?
Cartilage is a supple tissue which allows for facial movement as well as providing a lightweight supportive structure in the external ear, and the tip and septum of the nose. In other regions it acts as a shock absorber, cushioning areas where bone meets bone and preventing abrasion and damage. A joint would also not be able to bend without ...
What is the third most common type of cartilage?
Hyaline Cartilage. The third and most widespread type of cartilage is hyaline. Bones develop from hyaline cartilage. The supporting skeleton of a fetus is actually hyaline cartilage that later becomes ossified into bone. This ossification process ends at puberty as the cartilage turns to bone, with the exception the joints.
What Are the 3 Types of Cartilage?
Although there are areas of overlap, the 3 types of cartilage in the human body are:
What is the C-shaped piece of cartilage that acts as a shock absorber in the knee joint?
The meniscus (the C-shaped piece of tough, rubbery cartilage that acts as a shock absorber in the knee joint), and. The temporomandibular joint (TMJ) or jaw joint. The toughness, flexibility, and extra fibers of fibrous cartilage makes it ideal for certain attachment points of ligaments and tendons.
What type of collagen is found in fibrous cartilage?
Like all cartilage, fibrous cartilage contains type II collagen. However, fibrous is the only one of the 3 types of cartilage that also contains type I collagen, which is the form of collagen found primarily in bones, skin, tendons, and ligaments.
What happens to cartilage as you age?
But as we age, it’s often a different story. If you have aches, pain, and stiffness regularly —particularly if it occurs at a specific joint—you are most likely starting to experience the effects of joint cartilage degeneration, a form of arthritis. Age takes its toll on all body tissues, including cartilage, which is a type ...
Why is cartilage unique?
All cartilage is unique in that it doesn’t have a blood supply, nerve connections, or connections to the lymphatic system like other structures in the body. This lack of blood and lymph supply makes the growth and healing of cartilage slow and challenging.
Where is fibrous cartilage found?
Fibrous cartilage is found in: The intervertebral discs (the cartilage cushions between each vertebral in the spine), The capsules that surround joints, such as the joint where the pelvic bones meet in front (the pubic symphysis), The meniscus (the C-shaped piece of tough, rubbery cartilage that acts as a shock absorber in the knee joint), and.
What is cartilage in joints?
Cartilage is a connective tissue that acts as a cushion between the bones to protect our joints by absorbing. Store. Locations.
Why does cartilage wear out faster?
A sudden traumatic event, such as a sports injury, can injure the cartilage surface and potentially cause a weak spot in the cartilage. If weak spots are present, cartilage can break down faster with normal forces. While the damage may be small, cartilage will wear faster with weak spots.
What Causes Joint Pain?
There are a number of structures that do cause pain. The lining of the joint (synovial lining) is rich in nerve endings that sense pain. This lining is responsible for producing healthy fluid and lubricating substances. In diseases such as arthritis, the synovial lining can become bumpy and painful. It will also produce abnormal inflammatory fluid that act as solvents, breaking down tissue, on the other structures in the joint. The secret may be in the sauce, figuring out what’s in that fluid and how to control the synovial lining is one of the keys to halting arthritis.
How do stem cells help cartilage?
Stem cells can help cartilage to regrow but it is inconsistent and minimal at this time (despite what you may have heard). They can, however, improve the quality of the remaining cartilage, the strength of the bone, reprogram the synovial lining so that it produces healthy protective chemicals instead of destructive ones, and strengthen the ligaments and tendons so that there is better stability around the joint. Using stem cells in this way requires working with a highly trained physician who performs the proper analysis and creates and executes a procedure to precisely inject the tissues that are in most need of improvement. Receiving a stem cell injection blindly into a joint by someone who dabbles in this approach is not the way to go. To understand why Regenexx is different, click here.
How does synovial lining help the bone?
They can, however, improve the quality of the remaining cartilage, the strength of the bone, reprogram the synovial lining so that it produces healthy protective chemicals instead of destructive ones, and strengthen the ligaments and tendons so that there is better stability around the joint.
What is bone marrow lesions?
But there are times when the bone in areas of decreased amounts of cartilage begins to breakdown and become swollen representing little micro-breaks in the framework of the bone. This can be painful (not always) and can only be seen on an MRI. These areas are called bone marrow lesions (BML’s).
Why is it important to have stem cells around joints?
It is also important to make sure that there is stability around the joint – that is, the ligaments, tendons, muscles, and nervesare healthy and functioning normally and in a balanced way. Stem cells can help cartilage to regrow but it is inconsistent and minimal at this time (despite what you may have heard).
Overview
- Cartilage is a type of connective tissue found in the body. When an embryo is developing, cartila…
Cartilage is a unique tissue type because it doesn’t have blood vessels or nerves. Instead, cartilage cells (known as chondrocytes) are found in a gel-like “matrix” that provides nourishment to the cells. Cartilage has a unique structure that makes it a strong but flexible tissue. - What are the different types of cartilage?
Three types of cartilage exist in the body: hyaline, fibro, and elastic cartilage. Below is an explanation of each.
Elastic
- Elastic cartilage is found in the ear and epiglottis (located in the throat) as well as parts of the nose and trachea. This cartilage serves to provide strength and elasticity to organs and body structures, such as the outer ear.
Fibro or fibrous
- Fibro cartilage is found in special pads known as menisci and in the disks between your spinal b…
Doctors consider it the strongest of the three cartilage types. It has thick layers of strong collagen fibers.
Hyaline
- Hyaline cartilage is the most common type in the body. This cartilage type is found in the larynx, …
The term hyaline comes from the Greek word “hyalos,” which means glassy. Hyaline cartilage appears slightly glassy under a microscope. This cartilage type has many thin collagen fibers that help to give it strength. However, hyaline cartilage is considered the weakest of the three cartila… - How can cartilage become damaged?
Cartilage can become damaged after an injury or through degeneration, which is wearing down over time. Some of the common conditions related to cartilage degeneration include:
Chondromalacia patellae
- This condition, also referred to as runner’s knee, occurs when the articular cartilage over the kneecap breaks down. Factors such as injury, overuse, poor alignment, or muscle weakness can all lead to the condition. Chondromalacia can cause bone to rub against bone, which is very painful.
Costochondritis
- This condition occurs when the cartilage that connects the ribs to the breastbone becomes inflamed. While the condition is usually temporary, it can become chronic. The condition causes uncomfortable chest pain.
Herniated disk
- When the gel-like material inside the cartilage disk protrudes through the outer cartilage, it’s kno…
Unfortunately, cartilage breakdown can be a part of the body’s natural degenerative process. Steps like maintaining a healthy weight, practicing flexibility and strength-training exercises, and avoiding overtraining may help to reduce the rate at which cartilage breaks down.
Abrasion arthroplasty
- This procedure involves using a special high-speed instrument called a burr to create small holes below damaged cartilage to stimulate cartilage repair and growth.
Autologous chondrocyte implantation
- This cartilage repair technique requires two steps. First, a doctor removes a healthy piece of cart…
The person then goes to surgery where the damaged cartilage is removed and replaced with the newly grown cartilage. A surgeon also performs other repairs. Because this approach requires multiple surgical procedures, doctors usually only perform it on younger individuals who have a …
Microfracture
- This surgical technique involves removing damaged cartilage and then making small holes just beneath the cartilage in an area of bone known as the subchondral bone. This creates a new blood supply that will ideally stimulate healing.
Drilling
- The drilling approach is similar to microfracture. It involves making small holes in the subchondral area as a means of stimulating healing and new cartilage growth by increasing blood supply.
Osteochondral autograft transplantation
- This approach involves taking a piece of healthy cartilage from a non-weight-bearing area of the body and applying it to a damaged area. This type is usually only used on a small area of damage because a surgeon cannot take an excess of healthy tissue.
Osteochondral allograft transplantation
- Unlike the other tissue grafts, an allograft comes from a cadaver donor, not the person themselv…
Although doctors can perform these procedures to promote healing, the cartilage may grow at a slow rate. Doctors will likely recommend physical therapy and other techniques in the meantime to promote mobility. - Researchers are exploring new ways of healing and treating damaged cartilage besides increasi…
However, these approaches are still in the clinical trial stages and will take time and testing before new techniques emerge.
