Hyaline Cartilage
People also ask which type of cartilage is the most common and also the weakest?
Hyaline cartilage has widely distributed fine collagen fibers (Type II) that strengthen it. The collagen fibers can hardly be seen in sections. It has a perichondrium and is the weakest of the three types of cartilage.
And where is hyaline cartilage found?
Hyaline cartilage matrix consists mainly of type II collagen and chondroitin sulfate, both of which are also found in the elastic cartilage. Hyaline cartilage is found on the ventral ends of the ribs, in the larynx, trachea and bronchi, and on the articular surfaces of bones.
Similarly, it is asked what do all types of cartilage have in common?
These tissues all have chondrocytes within lacunae within an extracellular matrix. This tissue provides support with flexibility and elasticity.
What types of cartilage are there?
There are three different types of cartilage: elastic (A), hyaline (B), and fibrous ( C). In elastic cartilage, the cells are closer together creating less intercellular space. Elastic cartilage is found in the external ear flaps and in parts of the larynx.
Where is bone found?
It consists mainly of compact bone with lesser amounts of marrow, within the medullary cavity and areas with spongy cancellous bone at the ends of the bones. Most of the bones in the limbs, including the fingers and toes, are long bones.
How is cartilage made up?
Cartilage is a group of tissues produced by chondrocytes characterized by a relative lack of vascularity. It consists of cells surrounded by a specialized extracellular matrix composed mainly of type II collagen and proteoglycans, often in the form of proteoglycan aggregates.
Why is cartilage important?
Cartilage connective tissue is important because it provides support but is less rigid than bone. It also allows for some flexibility of movement but has more stability than muscles. The extracellular cartilage matrix is produced by cells called chondroblasts.
What causes cartilage damage?
Articular cartilage can be damaged by accidents, such as a crash. B. a tear of the anterior cruciate ligament (ACL). ) or slowly degenerate over time, eventually leading to osteoarthritis. Poor joint alignment, excess weight, excessive activity, overuse, or injury can cause cartilage to wear down.
What is bone made of?
Composed primarily of collagen, bone is living , growing tissue. Collagen is a protein that makes the skeleton soft, and calcium phosphate is a mineral that gives strength and hardens the skeleton. This combination of collagen and calcium makes bones strong and flexible enough to withstand stress.
Where is areolar tissue located?
The areolar tissue found in the skin binds the outer layers of skin to the layers below lying muscles. Areolar tissue is also found in or around mucous membranes and around blood vessels, nerves, and the body’s organs.
What type of tissue is cartilage?
Connective tissue
Connective tissue
What is knee cartilage made of?
Articular cartilage is hyaline cartilage and is 2 to 4 mm thick. Unlike most tissues, articular cartilage has no blood vessels, nerves, or lymphatic vessels. It consists of a dense extracellular matrix (ECM) with a sparse distribution of highly specialized cells called chondrocytes.
What causes weak cartilage?
Causes. Direct hit – when a joint receives a strong impact, such as in a bad fall or a car accident, the cartilage can be damaged. Inflammation, breakdown and eventual loss of cartilage in the joints is called osteoarthritis. Sedentary lifestyle – joints need regular exercise to stay healthy.
How many types of cartilage are there?
three types
What do lacunae do?
Between the matrix rings are the bone cells (osteocytes) in spaces called lacunae. Small canals (canaliculi) radiate from the lacunae to the osteonic (Haversian) canal to provide passageways through the hard matrix.
What is cartilage, what is its function?
Cartilage is flexible connective tissue found in many parts of the body. It can flex slightly but resists stretching. Its main function is to connect bones together. It is also found in the joints, chest, ear, nose, throat and between the back bones.
What is the main difference between the different types of cartilage?
Elastic cartilage contains more and larger chondrocytes than hyaline cartilage. They are more densely packed and have only one chondrocyte per gap. The entire cartilage is covered by perichondrium. Shows less accumulation of glycogen and lipids than hyaline cartilage.
Does cartilage absorb shock?
Shock absorption.. Articular cartilage acts as a shock absorber that protects bones from impact during a weight-bearing activity such as walking or jogging.
Where is cartilage located?
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. Between the vertebrae in the spine.
How does cartilage grow?
Cartilage can grow in two ways: Interstitial growth – Chondrocytes grow and divide, depositing more matrix within the existing cartilage. Appositional growth – new surface layers of matrix are added to the already existing matrix by new chondroblasts from the perichondrium.
How does cartilage heal?
Although articular cartilage cannot regrow or heal itself, the one underneath does lying bone tissue can. Doctors make small cuts and abrasions on the bone under the area of damaged cartilage to stimulate new growth. In some cases, the damaged cartilage is completely removed to perform this procedure.
