What cartilage covers the diaphysis of long bones?
Articular cartilage
Articular cartilage –a layer of hyaline cartilage covering the epiphyses for protection purposes . Periosteum – a layer fibrous connective tissue covering the diaphysis ; also involved in the formation and repair of a bone .
What is an example of diaphysis?
Diaphysis – Refers to the main part of the shaft of a long bone. Long bones, including the femur, humerus, and tibia, all have a shaft.
What part of the bone is covered by articular cartilage?
In a joint, hyaline cartilage is referred to as articular cartilage. This is because the cartilage covers bones’ surfaces where they articulate, or meet to form the joint. For example, at the knee joint, the top of the tibia, the bottom of the femur, and the back of the kneecap are covered with articular cartilage.
Which of the following is an example of a long bone?
Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges). Long bones function as levers; they move when muscles contract.
What type of cartilage is articular cartilage?
Articular cartilage is hyaline cartilage and is 2 to 4 mm thick. Unlike most tissues, articular cartilage does not have blood vessels, nerves, or lymphatics. It is composed of a dense extracellular matrix (ECM) with a sparse distribution of highly specialized cells called chondrocytes.
Where is articular cartilage found?
joints
Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction. Articular cartilage can be damaged by injury or normal wear and tear.
What is diaphysis of a long bone?
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow.
Which of the following bones contains a diaphysis?
long bone
Diaphysis. The diaphysis is the shaft of the long bone, the main body. The diaphysis is a tube with a hollow center called the medullary cavity (or marrow cavity). The wall of the diaphysis is made up of compact bone, which is dense and very hard.
What are the examples of cartilage?
Cartilage: The three types of cartilage
- Hyaline – most common, found in the ribs, nose, larynx, trachea. Is a precursor of bone.
- Fibro- is found in invertebral discs, joint capsules, ligaments.
- Elastic – is found in the external ear, epiglottis and larynx.
What is cartilage give example?
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.
What is an articular cartilage?
The bones that meet at synovial joints are covered with a thin layer of cartilage known as articular cartilage. (Articular simply means “having to do with joints.”) Articular cartilage forms a smooth, durable covering (almost the consistency of linoleum) at the end of each bone in the joint.
Where on a long bone is articular cartilage found quizlet?
Where is cartilage found on the surface of a long bone? Cartilage is found on the proximal and distal epiphysis of the bone where is articulates with other bones.
Why is articular cartilage an important part of long bone structure?
Why is articular cartilage an important part of long bone structure? Articular cartilage allows bones to rub together with reduced friction at joints. As a result of the increase of testosterone at puberty for males: appositional bone growth increases.
What are examples of three types of cartilage?
There are three types of cartilage:
- Hyaline – most common, found in the ribs, nose, larynx, trachea. Is a precursor of bone.
- Fibro- is found in invertebral discs, joint capsules, ligaments.
- Elastic – is found in the external ear, epiglottis and larynx.
What is the articular cartilage?
Articular cartilage is a thin layer of specialized connective tissue with unique viscoelastic properties. Its principal function is to provide a smooth, lubricated surface for low friction articulation and to facilitate the transmission of loads to the underlying subchondral bone.
