Does articular cartilage covers the diaphysis of long bones?
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 does the articular cartilage of a long bone cover?
Articular cartilage (AC) is a connective tissue covering the ends of bones that functions as a load-bearing, low-friction, and wear-resistant surface to facilitate joint movement.
What is the diaphysis of a long bone covered by?
cortical bone
The outer walls of the diaphysis (cortex, cortical bone) are composed of dense and hard compact bone, a form of osseous tissue. Figure 6.3. 1 – Anatomy of a Long Bone: A typical long bone showing gross anatomical features.
Where is articular cartilage found on a long bone?
The diaphysis is the shaft of the long bone. It has compact bone with a central cavity. The articular cartilage is found on the ends of long bones.
What surrounds the diaphysis?
It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs….

Why doesn’t the periosteum cover the articular cartilage of a long bone?
The periosteum doesn’t cover the portion of bones that contains articular cartilage, which is the cartilage found in joints that keeps the bones from rubbing together. It is not as tightly packed and contains cells that help in bone growth and repair.
What is the diaphysis?
The diaphyses (singular: diaphysis), sometimes colloquially called the shafts, are the main portions of a long bone (a bone that is longer than it is wide) and provide most of their length.
What is diaphysis made of?
The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat).
What type of bone is found mainly in the diaphysis?
compact bone
The compact bone is a dense bone found in the diaphysis. Its repeated pattern is arranged in concentric layers of solid bone tissue.
Does periosteum cover articular cartilage?
What Is the Periosteum? The periosteum is a membranous tissue that covers the surfaces of your bones. The only areas it doesn’t cover are those surrounded by cartilage and where tendons and ligaments attach to bone.
